Wikimedia Apps/Android FAQ/ja

Where can I download the app?
You can find our app on the Google Play Store: open the Play Store app on your device and search for "Wikipedia".

If your device does not use Google services, you may also find the app on other third-party app stores such as F-Droid, or by downloading the latest APK directly.

Androidのアプリとモバイル版ウィキペディアとの違いは？
ウィキペディアアプリでは、コンテンツの検索・閲覧を最適かつ能率的に行うことができます. 専らこのアプリを使用することで、データ使用量を抑えた状態でさらに記事の読み込みを速くすることが可能となります. また、お好きなAndroidアプリとの間で、より信頼性が高く安定した連携を行うこともできます. 「後で読むリスト」にページを保存する、記事中のコンテンツや画像をお好きなソーシャルメディアアプリで共有するなどウェブ版ウィキペディアでは使えない機能も追加されています.

How do I donate to Wikipedia?
You can donate at any time by going to the "More" menu in the main screen and selecting Support Wikipedia. Unfortunately we cannot currently accept donations using Google Pay, or using your Google Store credits.

I already donated; why I am getting asked to donate again?
Due to our strict privacy guidelines, we don't actually connect your app usage or user account to your donation history. This means you may see a donation request in the app even if you have previously donated on the web.

Do I need to be connected to the Internet to use the app?
You do need a connection to download articles, and to use the Explore feed. However, if you save articles to your reading lists, they will be available for later reading, even without an internet connection.

サポートしているデバイスは?
このアプリはバージョン 5.0 (Lollipop) 以降の Android で使えます.

I see vandalism in an article. What should I do?
If you see text or images in an article that are clearly vandalism, you can always edit the article by tapping the "pencil" icon to the right of the article section that contains the vandalism. You can then remove the offending text and publish the edited content.

I see information that is biased or factually incorrect. What should I do?
If you see text in an article that may be incorrect, biased, or generally low-quality, you can join the discussion about that article on the corresponding Talk page for the article. You can access the Talk page by scrolling near the bottom and tapping the "View talk page" link.

How do I report a typo or other error in an article?
Wikipedia is the world's largest encyclopedia that anyone can edit! If you see a typo or other error in an article, click the "pencil" icon or highlight any text and tap "Edit here" from the popup menu. This will show the Wikitext of the article which you can then edit and save.

If you make lots of edits, we recommend you log in to your account, so that you can keep track of your work, talk to other editors and join the worldwide Wikimedia community.

Search
You can search Wikipedia from any of these locations in the app:


 * From the Explore feed in the main screen, by tapping the "Search Wikipedia" box at the top.
 * By tapping the "Search" icon in the bottom toolbar in the main screen.
 * While reading an article, by tapping the "Search" icon in the top toolbar.

Search within an article
From the top-right menu (three dots), select "Find in page". You will be able to type text to search within the current article, and the search results will be automatically highlighted and scrolled into view.

Explore feed
The home screen of the app features a feed of recommended content for reading. Each "card" in the feed represents a single article, or a short list of articles, for you to read. The types of cards you might find in the feed (depending on their language availability) include:
 * In the news: 直近のイベントの記事.
 * 話題の記事︰その日最も訪れられた記事(総閲覧回数に基づく).
 * 公開された記事︰その日ウィキペディアで公開された記事.
 * Featured picture: ウィキメディア・コモンズでその日公開された写真.
 * 続けて読む︰タブ内で開かれている記事をすぐに見返す.
 * Because you read︰最近読んだ記事に基づいて提案される短いリスト.
 * On this day: events in history on this day.
 * おまかせ表示︰ランダムに選ばれた記事を開く.
 * 今日の記事︰本家ウィキペディアのメインページを開く.
 * On this day: Events in history on this day.

How can I customize the feed?
If you don't want to see a particular card in the Explore feed, you can tap the overflow menu on that card (three dots at the top-right), and tap "Hide this card".

You may also tap the overflow menu on any card (three dots at the top-right) and select the "Customize the feed" option, which will allow you to choose which types of cards to show, the order in which they will appear, and the languages for which they will be shown.

Reading lists
You can add an article to a reading list, which acts as a sort of bookmark of the article. You can have more than one reading list so that you categorize the articles in your lists. Articles saved to a list are made available offline by default so that you can read them later. If you do not want certain articles to be available offline, you can go to the reading list, and press-and-hold the specific article. You will then see a list of options for that article, which includes an "Available offline" checkbox. You may access all of your reading lists by tapping the "My lists" button on the main screen.

When you are logged in to the app, your reading lists are automatically synchronized to your Wikipedia account, so that your lists will be restored if you install the app on a different device, or uninstall/reinstall it on the same device. Your reading lists will also be available if you log in to the iOS version of the app. However, at the moment your reading lists are not accessible from the desktop or mobile web version of the Wikipedia website.

Readability and themes
When reading an article, tap the "Theme" button in the bottom toolbar. There you will see numerous options, including:


 * Increase or decrease the text size for reading articles.
 * Change the color theme between Light, Sepia, Dark, or Black. (The Black theme is particularly useful for devices with an OLED display, since it will save battery power by keeping most pixels black.)
 * Whether to "Match system theme". Since Android itself now supports a light and dark theme, the app can automatically adjust to the system setting. If you do not want to match the system theme (i.e. if you want to use the Dark theme in the app, but keep the device in the Light theme, you'll need to unselect "Match system theme").
 * Whether to dim images. When using the Dark or Black theme, dimming images may be an additional benefit for distraction-free reading.

編集
記事の編集を始めるには、節のヘッダの隣にある 「鉛筆」をクリックします. ウィキペディアの記事は を使用してフォーマットされることにご注意ください.


 * 編集するにはログインが必要ですか?
 * 必要ありません. 利用者名を決めたりログインしたりしなくても構いませんが、編集すると IP アドレスがひも付けされ、そのページの履歴表示に公開されます.


 * 写真はアップロードできますか?
 * 現在のところできません.


 * ページの履歴やトークページを閲覧できますか?
 * 現在、アプリではこれをサポートしていません.

You can view links to the mobile web version of the history and the talk pages in the app.

Languages
Wikipedia content exists in more than 300 languages, and you can select one or more of those languages to be used in the app.

When the app is first installed, it defaults to the system language of your device. If you have more than one keyboard language installed, the app should automatically detect those languages and add them to its list of languages.

To change the Wikipedia language, go to the "More" menu in the main screen, tap "Settings", then select "Wikipedia languages". From there you can add, remove, and rearrange your preferred languages. (Your topmost language will be used by default when searching Wikipedia.)
 * ウィキペディアの言語を設定または変更

When reading an article, you can tap the "Language" button in the bottom toolbar to see other languages in which this article is available. (Note that not all articles will be available in all languages.)
 * 他の言語で読む

Does the app track me? Do you use my data?
Yes, some of your actions within the app are tracked, so that we can continue to improve our features. Sending usage reports can be deactivated by going to "Settings", which can be accessed from the "More" menu in the main screen, and unchecking "Send usage reports".

We also have crash reporting to help us fix bugs. This is separate from usage reporting. If a crash is detected, we automatically send reports to helps us find the reason and fix the issue (This really helps us a lot!). All collected data is anonymous. You can disable crash reporting by going to "Settings" and unchecking "Send crash reports".

What information do usage reports contain?
Various kinds of data are collected, the specifics of which can seen on the event logging page. For example, it records the average delay between typing a search term and receiving search results, or the number of times the Share button is clicked, or whether the font size was increased or decreased. We use a service called AppCenter to report crashes in the app. When you choose to send us a crash (which we're immensely grateful for!), it tells us where in our code the crash occurred (the stack track across all active threads), and other diagnostic information such as the Android version and device type. This data cannot be used to personally identify you. This is all used to better understand user engagement, and guides us to improving and enhancing the features that the app offers.

Why does the app need the Identity permission (GET_ACCOUNTS)?
This permission is required so that the app can integrate with your user account on Wikipedia, so that your preferences and saved pages will be synchronized between devices when you are logged in. （この機能は開発中です. ）

Why does the app need the Photos/Media/Files permission (WRITE_EXTERNAL_STORAGE)?
This permission is required because the app allows you to save images that you browse to your local device. It's also required so that the app can temporarily save images for sharing via other apps (as in Share a fact).

=== Why does the app need the Full Network Access permission (ACCESS_NETWORK_STATE, ACCESS_WIFI_STATE)? === This permission is used by the app to determine the state and quality of your network connection, and adjust certain aspects of its performance accordingly (e.g. loading lower-quality versions of images when on a limited connection).

Why does the app need the Startup (Boot Completed) permission (RECEIVE_BOOT_COMPLETED)?
The app provides a feature that lets you receive notifications on your device about your Wikipedia account.These can be notifications about articles that you've edited, messages on your Talk page, thanks from other editors, etc. This can be turned on if you login to your account and enable notification polling. The service that checks for notifications runs in the background, and needs to restart itself automatically if your device itself is restarted. This is why the app needs to receive an event when your device initially boots up. If you do not enable the Notification polling feature, then the Startup permission is not used for any other purpose.

Is the connection between the app and Wikipedia encrypted?
Yes, all network traffic from the app is performed over HTTPS.

I'm blocked from logging in or editing, what should I do?
If you have not made any edits to Wikipedia, but still find yourself blocked from logging in, creating an account, or making edits, it probably means that your IP address has been blocked, not "you" specifically. When you use your device on a mobile network, or on a shared WiFi connection, your IP address may be shared with many other users. These other users might have made unconstructive edits to Wikipedia, which resulted in blocking the IP address.

Note that the Wikimedia Foundation does not administer the blocking of IP addresses; instead, this work is done by a global community of volunteers.

For information about blocks and appealing a block on English Wikipedia, please see the information page at w:en:Help:I have been blocked.

My edits are being reverted / I disagree with certain administrative actions.
There is no central authority over Wikipedia. The Wikimedia movement is based in part on the premise that good articles are achievable through the checks and balances editors provide for each other. When editors disagree on how to achieve these goals, they must resolve disputes through consensus, drawing on the wider community where necessary. You can read more about the dispute resolution processes on English Wikipedia at w:en:WP:DR.

Reporting bugs

 * If the app crashes, it will automatically send a crash report to us, assuming you haven't disabled crash reporting in Settings.
 * If you see a bug (not a crash) or have a suggestion or feature request, you can send us feedback [mailto:android-support@wikimedia.org here].
