経過をフォローするには
Phabricator Epic として T273253 を作成、Android アプリのトークページに関して早期の改善を追跡し、本格的な分析につなげます. 来年いっぱい使って改善に取り組むため初期リリースに基づく開発を進め、2021年4月 – 6月には Android 機器を使ったコミュニケーションを掘り下げて調査する予定もあり、皆さんからのフィードバックをお待ちしています.

March 2022 – Sort and Search on Talk Pages, Starting Onboarding project, Testing Reading Focus Mode and Customizable Toolbar
During our March releases we started incremental updates to talk pages ahead of the refresh. The updates included search and sort at the topic level. Users are able to sort by Topic, date updated and date published.

In March the team started initial research to improve onboarding and guidance in the app. It was clear from our research for other features and requests made through the play store for features that existed in the app that improvements needed to be made to exposing features at the right time. Our first step for these improvements was to take stock of our existing onboarding prompts and tooltips.

In January we created the first version of Reading Focus Mode. Before releasing reading focus mode to production we wanted to ensure users were able to successfully turn reading focus mode off in order to edit. As we tested reading focus mode we also evaluated the usability of the customizable toolbar.

Observations

What works?
1. Onboarding / language - Tooltip is displayed for all participants - One candidate (FR) appreciated the full screen onboarding when editing article descriptions for the first time. This should be explored further in onboarding and guidance phase ([T301397](https://phabricator.wikimedia.org/T301397)) 2. Reading focus mode - Reading focus mode disabled by default as participants learned how it works - 4/5 understood what the reading focus mode setting does, understood differences when the mode is enabled - 5/5 had no issues going back to editing after turning on reading focus mode - 4/5 like the ‘Reading focus mode’ feature 3. Customize toolbar - Once arrived in the customization screen, 5/5 understood what the screen does. - 5/5 figured out how to drag&drop items (but 3/5 were dragging the labels first)

What doesn’t work?
1. General / Onboarding / Language - Tooltip wasn’t noticed by 4/5, participants scrolled and the tooltip disappeared 2. Reading focus mode - Likely related to the tooltip that disappeared → 3/5 participants had issues discovering the ‘Reading focus mode’ setting 3. Customize toolbar - Language: ‘actions and destinations’ in the task was confusing to almost all participants - All participants had issues finding ‘Customize toolbar’ - Interaction: 3/5 participants wanted to drag&drop the label on the customization screen in order to move items. - 3/5 had issues finding items in the overflow menu after moving them out of the toolbar (they had troubles making a connection between the toolbar and overflow menu) Based on the observations, we are considering the following changes to version 1 reading focus mode and customizable toolbar. 1. Onboarding / language - Keep onboarding tooltips visible when scrolling. Only proactively tapping “GOT IT” should dismiss the tooltip. 2. Reading focus mode - Make sure the Reading focus mode setting completely hides edit pencils, without having to refresh the screen (some participants experienced this) - `ADD ARTICLE DESCRIPTION`, `ADD IMAGE CAPTION`, `ADD IMAGE TAGS` CTA’s should be hidden when reading focus mode is enabled 3. Customize toolbar - Make sure the entire list item is draggable not only the icon on the right. Alternative concepts if this is not feasible: - Show a tooltip when users try to drag and drop the label instead of the icon - If tooltip does not improve the situation → consider moving towards a pattern that does not rely on drag on dropping - Terminology: Users don’t get the current wording ‘Actions and Destinations’, change the copy of the detail screen to: `Customize the bottom toolbar with 5 quick links you find most helpful.` - Discovery and usability (T302397) - Add an additional, sixth ‘More’ menu item to the bottom toolbar, since the feature is hard to discover within 'Theme' at the moment. - Move items from the overflow menu in the app bar (top right) to a bottom sheet that is triggered by the newly added sixth 'More' item in the toolbar. There were a number of bugs we fixed which included ensuring the content side bar reflected the proper positioning (T301074), showing the language code for language variants that are unnamed (T301919), long press menu not properly displaying "Define" and "Edit" (T302078z), and Wikibooks to Wikipedia works on mobile (T303123).

February 2022 – @Mentions, Native Revision history, Article and User Talk Page mockups, Customizable Toolbar and Reading Focus Mode Release
During our February releases we made minor improvements to talk pages for more and better functions.

The improvements includes a drop-down menu when users click a username that lets them choose if they want to go to a user talk page or user page.

We understand that some users may want to see who they are communicating with before sending a talk page message, whereas other users would like to go directly to a talk page; we hope that this release allows that flexibility.

Users are now able to edit talk pages as wikitext now, which is important for users that may post an error or typo in their talk page message and want to delete or modify it.

We also added a pattern to replies that pre-populates the user you are replying to on talk pages when hitting reply.

Users are also able to use the @ symbol to mention another user instead of having to use brackets and write out ping.

Additionally, when pressing @ and starting to type a name, the app provides a drop-down menu of user names.

We hope this change will make mentioning other users easier for Android users and also serves to ensure the person they are replying to receives a notification (T297912).

Last year the team released Watchlist, which introduced native diff views to the Android app. To build on this feature our designer created mockups for native revision history, something requested in the community wishlist. The engineers have started developing revision history. While we have started developing the feature we welcome feedback from the community regarding the latest designs of native edit history on our talk page or on Phabricator. We are especially interested to know if it would be helpful to allow filtering by tags, and how prominent the undo button should be. Please keep in mind undo is not the same as rollback, which means all users will see the undo button. We are also considering adding a rollback button for users that have those permissions.



In December 2021 we shared the mockups of Reading Focus Mode and the Customizable Toolbar. The team released both features in February and conducted user testing. The detailed results of the test can be found on Phabricator. The most notable results were:
 * Users understood how to turn reading mode off and on if they desired to make an edit
 * It was difficult to discover reading mode and the customizable toolbar with it being nested in Theme
 * Users had difficulty finding theme once they moved it out of the toolbar
 * It wasn't obvious to use the side icons to rearrange the toolbar

For that reason, the team will rethink our onboarding to these features through the next phase of our work, which is onboarding and guidance. Additionally we will add a more link in the toolbar, which is where users can access the customizable toolbar feature. We would also appreciate feedback on if we should use checkboxes to allow users to select what links are in their toolbar to address the difficulty people had with dragging an icon.



This month we took the feedback and learnings from previous months about how we should improve talk pages in the app and developed the following mockups:

One of the changes you will notice is that user talk pages and article talk pages are visually different. On the user talk page we display some of the most recent message at the subject view level and conversely for the article view we show the subjects and not any of the metadata from the message. The intention behind this difference is to make the user talk page feel more conversational and visually indicate the article topics are meant to discuss article edits. To further connect the article talk page topics to the article, we will display an image from the article in the header of article talk pages. User talk pages will show the name of the most recent person that has posted to indicate that the space is conversational amongst users and not necessarily article specific.

Previously there wasn't a visual distinction for template messages that often share helpful context and policy for article talk pages, in our proposed designs we drew inspiration from Desktop by distinguishing the top most template message from other talk page topics. In both article and user talk pages, users will be able to view archived messages in the app and subscribe to threads in order to receive notifications when someone has posted an updated to a talk page thread of interest.

We also changed the way users reply and read threads. Replies to a thread were at the same level and indicated with a reply icon. In our new designs, users can expand and collapse replies and we will now support inline replies. Additionally, whereas in the past users replied using a floating action button, with the addition of inline replies, reply actions will be under each post. This month we also fixed a number of bugs which included improving audio and media file support. There were also bugs fixed related to the article layout on this day and making the article doesn't close out when returning from webview. The confusion between Chinese language variant codes has been fixed in T298448. Long references on small screens are now fully viewable T298269.

Finishing our work on notifications, there was a back end issue where notifications weren't being properly associated with the right place in a talk page. As of February, talk page notifications take you to the right place in the discussion T296018.

January 2022 – Talk page discoverability exploration, exposing project talk pages and accessibility report
In January we continued our work on enhancing talk pages by exploring pathways to make accessing talk pages more discoverable without it being intrusive. Our explorations for discoverability took into consideration the feedback we received in November and December from new and experienced users. Now that the Android app has Reading mode, a feature where users can hide editing features, when reading mode is off, users will see a talk page bubble that shows the number of active discussions for an article. Once a user clicks the talk bubble they will view a preview in a side panel of the active discussion topics. Users will be able to expand the side panel or click a topic to see the full view of the article talk page. The work can be tracked at T298814and T299033.



As described in T295071, when a user clicked on a username that doesn't have a profile page an error message popped up reading "This page does not exist" with the option to dismiss, which wasn't helpful and was a different experience than Desktop. The team updated the error message to provide more context and it is now more aligned with Desktop experiences.



The team made various tweaks to the app to improve accessibility, which was written about in detail by one of the Android app developers, Cooltey Feng. One of the outstanding items to address as a result of the report is if our experience for users with screenreaders should be improved or standard. The team is looking to consult screenreader users to conduct an evaluation of the app experience and provide feedback. Please comment on our talk page or email android-support@wikimedia.org if you can provide feedback on the app experience while using a screenreader.

Previously when users navigated to project pages in the app, talk page links were broken. As of our January release project talk pages can be properly accessed in the app.

December 2021 – Talk page survey results (experienced users), IP notifications and reading focus mode
As a follow-up to the survey from new users the team investigated ways to improve. One investigation included investigating the possibility of not using the RestBase endpoint for retrieving talk pages and instead using the regular MediaWiki API to get better talk page performance. As detailed in T295687, our team is unable to do so at this time because it requires an improvement of the performance of change propagation and/or cache updates of the REST endpoint. We have put in a request for backend teams to pick this up with the hopes of faster talk page performance in the future.

The team discovered that talk page notifications do not always lead users to the right subject line, rather it takes them to the general talk page. This bug was caused by changes to the DiscussionTools project. The team has been collaborating with the Editing team to fix this bug and the work is documented in T296018. As of December 15, 2021, unregistered editors in the Android app will receive talk page notifications T291481, which is important for reaching anonymous editors.

Users are now able to filter notifications by Wiki and notification type in the home center T294035, while also accessing settings to update preferred language settings in the filter view.



To help collaboration, users can now see their notifications even while offline T287955.

In October the team launched a survey to learn about the desires of experienced users for their talk pages experience in the Android app. We specifically surfaced the survey in the app to English Wikipedia talk page users in Nigeria and India, Arabic and French Wikipedia talk page users in DR Congo, Mali, Morocco and Egypt, as well as Japanese Wikipedia editors and Hindi Wikipedia Editors and received responses from 54 participants. The full results can be found at the bottom of the protocol page. The key takeaways from this survey was that users believe talk pages need better onboarding and education on how to use them and the distinction between article and user talk pages. There were requests for comprehensive communication flows when edit changes occur, and easier ways for users to seek assistance. Users requested an ability to share talk pages, which has been implemented in T295808. The lack of talk page discoverability in the article view was further highlighted in this survey. Respondents to the survey expressed the importance of encouraging users to review an article talk page when making an edit. It was highlighted that users involved in a talk page message should be pinged when someone has replied to them, which doesn't currently happen unless the user replying puts in the ping command for the user they would like to reach. Further, positive reinforcement and support for deleting and archiving messages that are no longer relevant were also surfaced as desired features.

What was very evident in our research was the flexibility needed so that our users unique needs are met when they are reading an article and prefer not to see editing tools compared to when they may want to edit and have a desire for specific editing tools or talk pages. With the requests for flexibility in mind, the team will release and test a customizable toolbar, which will allow users to choose which quick actions appear in the bottom bar in article view versus which things should go to the overflow menu and reading focus mode, a feature that hides the bottom quick actions toolbar on scroll as well as the edit pencils and call to actions. Reading mode will be off by default but accessible via Themes. The team will ensure users are able to recall how to turn read mode off so that we don't impede anyone's ability to edit.

November 2021 – Talk page survey results (new users), EditNotices and release of notifications home center
Building on the work we did to notifications last month, our team improved the notifications home center by adding [phab:T288068|search and filter]] functionality. We also improved the readability of the home center and added a new tabs called mentions, which includes all notifications that are generated by an action from other users, the categorization follows the policy that defines mention notification types. The team ran T2933447a usability test of our existing talk page experience on usertesting.com with new users to understand how discoverable talk pages are and if users understand how to differentiate between user and article talk pages. Additionally, we wanted to know what elements work well even in low context. Finally, we hoped to identify possible opportunities for improvements that we could surface to experienced users in the survey we ran in app. Our test users edited on Arabic, French, Hindi, Indonesian and Japanese Wikipedia.

From the test we learned the following things worked:


 * Users understood how to create new topics and reply to threads
 * Participants mostly understood that the article messages were from other users.
 * Participants described what a revert is, in their own words, well
 * Link in the footer: Some participants accessed talk pages via the link in the footer intuitively
 * Discovery of notifications: the work on the new placement for notifications paid off, people had no issues discovering the bell icon

From the test we learned the following things do not work well in our existing experience:


 * Users had a difficult time finding the link to article talk pages in the overflow menu, some participants tapped the edit pencil to access talk pages
 * There was a slow performance when attempting to submit on when using talk pages on Japanese Wikipedia
 * Users didn't understand the distinction between how to use article talk pages and user talk pages
 * There was a disorientation when tapping items within notifications home and navigating to Commons talk pages
 * Lack of understanding for the diff view and of edit summaries
 * At times there were no active keyboard and the reply button was missing

Based on the results of the test, the team generated investigative tasks, which can be found linked to this epic on Phabricator.

We fixed some bugs which includes presenting edit notices and fixing a bug where users lost their open tabs.

October 2021 – Outcomes of the ABC test, more updates to notifications and the launch of talk pages work
Last month we conducted research to understand how to improve the notifications experience for our users. Our goal was to ensure people are accurately receiving important messages from other users and the system, and able to understand and engage with the messages they receive. In last month's update we shared the outcomes of our qualitative research. We now have the outcomes of our ABC test where we evaluated which iconography and placement of said iconography in the app would best improve discoverability of notifications.

By changing the placement of the notifications iconography from the overflow more menu to the top navigation bar we saw an increase in interactions by 121.4%. The activity data was isolated by a seven day average of daily unique users. We further evaluated the impact on our target user groups to ensure our decision making is equitable. Based on this evaluation we saw an increase in interactions by 102.19% for users in Nigeria and India using English Wikipedia, 108.90% for users in Morocco, Egypt, DR Congo, and Mali on French and Arabic Wikipedia, 77.23% for Hindi Wikipedia users, 74.07% for Indonesian Wikipedia users, 147.83% for Japanese Wikipedia users. Based on this information, we made a final decision of ensuring the notifications icon lived in the top bar.

Our next test evaluated if our existing more icon, bell icon or the inbox icon would yield more clicks. Our data indicated the inbox had the highest level of clicks overall and across user groups, the bell icon was the next most favorable icon, followed by more. However, within our target user groups, Indonesian Wikipedia editors and Hindi Wikipedia editors, marginally clicked the more icon over the bell icon. Although the inbox was most favorable, when compared to our qualitative feedback, we learned that users expected to enter an actual inbox when clicking an inbox, and the bell icon was more closely associated with notifications. Additionally, across other platforms, the bell icon is being used to indicate notifications, so for the sake of parity and to not confuse users, our team chose the bell icon.

The next phase of our communication work is to improve the talk page experience in the Android app. While we currently have talk pages, it is important that the experience graduates from functional for experienced users to easy to use by all users, especially those that may need to use them the most. In order to better learn what gaps exist, we are launching two surveys. One survey will be conducted on usertsting.com with new users, so that we may learn what gaps exist for users that may be new to the Android app. You can find that protocol on Phabricator. The other will be for more experienced users that have visited and used talk pages in the Android app before. You may view the survey for experienced users at Wikimedia Apps/Team/Android/Communication/UsertestingOctober2021 and answer questions on talk page.

We also made minor upgrades which included improving how we handle the topmost welcome message on user talk pages, which can be reviewed on Phabricator.

September 2021 - In-app notifications and survey results
The outcomes of the qualitative survey collecting feedback about Notifications can be found on the protocol page.

Through our qualitative research we learned:


 * The top right positioning of the notification icon was most popular
 * The bell icon was most closely associated with notifications. While the inbox tray was a popular choice, it was associated with messages and notifications span beyond human-to-human contact
 * Users were in favor of having a mention tab in the Notifications Home Center
 * Users generally found filtering capabilities within the notifications home center important
 * There was a request for more context for reverts

To compliment the qualitative feedback we've received, the team launched an ABC test to get the final quantitative confirmation of how the discoverability of notifications changes if a bell icon is used in the top right hand corner when compared to the more and inbox tray. The initial details are available in Phabricator via ticket T290995.

As requested by the community and based on the survey feedback the team made notifications more discoverable in the article view.

The final iconography will be decided in October after our ABC test.

In addition, the team released the following minor updates:


 * An ability to to delete individual items in recent searches T276770
 * Enable users to undo a talk page message a few seconds after posting and return to edit mode to make changes T287594
 * Expose the last time a talk page has been edited so that users can easily review the edit history T274836 and T287593

August 2021 - Minor bug fixes
In August, the engineers focused primarily on tech debt and bug fixes raised by users as the rest of the team processed feedback from the community to turn them into features.

26 July 2021 - User testing notifications placement and workflows
The team is requesting feedback about potential changes to notification placement in the Android app and the subsequent workflows. Please visit the user testing protocol on MediaWiki and share your feedback on the talk page.

2021年7月12日 - トークページの認識しやすさの向上
Android アプリでは現状、すべての通知と警告をサポートしています.

しかしながら、アプリ使用中に通知を探すのは簡単ではありませんでした. 2021-2022年会計年度の目標として、このユーザー体験を改善するつもりです.

2021年7月-同9月期の更新ではアプリ内の通知の探しやすさを高め、ロック画面で通知を表示できるようにします. 予定としては2021年12月までに通知ホームセンターを導入、直感的に使えるインボックスとインターフェースを設置します. Android のシステム要素との統合を意識し、プラットフォームに置く機能のなじみやすさと使いやすさを盛り込んで設計とビルドを実施します.

2021年7月から同12月期にフォーカスする対象はログイン利用者で1回以上の編集を行った人たちとしますが、以前の数ヵ月にわたり進めてきた作業を基盤に、ログアウトした利用者が警告に気づくよう2022年の年初実現を目指します. ログアウトした利用者には、（アカウント登録へ導くため）コミュニケーションツールにオンボード体験の取り入れを試みる予定です. これは他のログアウトした利用者を対象とする肯定的な定着促進と登録勧誘のワークフローに追加する位置づけです.

2021年5月10日 - エラー処理メッセージの更新
アプリ内のエラーメッセージ処理に関してチームでいくつか更新を実施、数週間後には製品に導入の予定です. 変更点の詳細はT170726、T276142、T276139を参照してください.

さらに改善をするべきと認識しており、現状でこれら改善点はリリースにふさわしいとのフィードバックを活用し、今後も Android のエラーメッセージの処理法とコミュニケーションシステムの改善を進めます.

2021年3月30日 - ネーティブのトークページならびにウォッチリストの更新
さまざまな役務者との協調により、最近の導入によるトークページとウォッチリストを評価、改善の可能性を探りました. 直近のリリースで下記の変更を実施しています.


 * 再読み込みしたとき、返信ボタンがメッセージ作成欄の邪魔にならないようにすること.
 * 記事のトークページへのリンクを記事の下部ではなくドロップダウンメニューに収容、記事のドロップダウンからウォッチリストが開くようにアクセスを追加
 * 「この記事について」欄の長さを調節、目次一覧でもっと目立つ長さにまとめる.
 * トークページの投稿の題名を囲み形式に

今後、改善を検討している対象は以下を含みます.


 * インラインな返信が節の最下部ではなく、その行に表示されるようにする.
 * 依存条件：API はバックエンドチームが担当
 * トークページの未読の項目を示す青い丸印のデザイン変更もしくは再検討.
 * 特定のトークページの最終の変更履歴を明示.
 * ウォッチリストならびにトークページの使い方入門を作る.

021年2月2日 - ウォッチリストとトークページの実装
Android 版ウィキペディア・アプリの最新版リリースはGoogle Play ストアに上がり、盛り上がっています (Google 未導入の機器向けにはスタンドアローンのダウンロードをご提供. ) この更新の主なハイライトは次の通りです.


 * ウォッチリスト：ログインするとメインの画面からウォッチリストを開けるようになりました. メイン画面下部の "More" メニュー > "Watchlist." と進んでください. アプリで多言語を選んである場合、複数言語のウォッチリストを1本にまとめて表示します. また画面上部のツールバーでアイコンをタップすると表示する言語版を指定できます. ウォッチリストの項目をタップ、その更新版の詳しい差分を閲覧できます. もちろん、閲覧中の記事をウォッチリストに追加するには、ツールバーの上段右上 > "ウォッチチリストに追加" で指定できます.
 * トークページ：記事トークページと利用者トークページの表示はネーティブになりました. 記事を閲覧したときトークページを開くには、ページ下部へスクロール > "トークページを表示"  と進みます. 他の利用者自身のトークページは利用者とのやりとりが発生するさまざまな場所からも開けるので、たとえば利用者自身のウォッチリスト、さまざまなプッシュ通知の受信時（例：利用者自身のトークページに誰かが投稿） 、あるいは記事トークページや他の利用者のトークページからも自分自身のトークページを開くことができます.

上記の大がかりな更新に加え、今回のリリースはバグ修正やデザインの手直し、パフォーマンスの最適化を多数盛り込みました. ぜひ実際に使って、毎度のことですがフィードバックをお待ちしています. 特にウォッチリストの反響は Phabricator のタスク T273254 で、同じくトークページ関連は T273253. で募集します. このトークページでも投稿を受け付けます.

特記事項：この更新版は私たちの同僚で友人の故ベルンド・シッツマンを追憶したものです. 故人は優れた開発者で人柄も素晴らしくアプリが今日の姿になり得たのもひとえに故人のおかげです. ご冥福を祈ります.

2018年12月 - Echo 通知を Android に導入
Android チームは2018年に、Echo 通知の導入に取り掛かりました. プロジェクト終了時期には、以下の種類の通知が実装されました.


 * システム- システム発の通知
 * マイルストン-  到達した編集回数
 * 感謝- 受信者の編集に対する感謝
 * 差し戻し- One- of 受信者の編集のうち、どれかが差し戻された
 * トークページ- トークページからの通知
 * ログイン- 受信者のログインの動き
 * 言及- 受信者がどこかのページで言及された

さらにくわえて、チームは投票の通知を実装、アプリが新規通知をバックグラウンドで確認するため、データの使用を許可しました. 2021年4月時点では、この機能は既定では無効です.

プッシュ通知の制限
本来の実施アプラーチでは、リアルタイムのプッシュ通知がうまく作動しない既知の問題があります. これらの制限が原因で、通知は最大10分遅延しています.
