WordPress for Android

If you're just looking to install WordPress for Android, you can find it on Google Play. If you're a developer wanting to contribute, read on.

Build Instructions

1. Make sure you've installed Android Studio.
2. Install npm using Node Version Manager(nvm), as described in step one from the Block Editor Quickstart guide
3. cd WordPress-Android to enter the working directory.
4. cp gradle.properties-example gradle.properties to set up the sample app credentials file.
5. In Android Studio, open the project from the local repository. This will auto-generate local.properties with the SDK location.
6. Recommended: The CI uses JDK11 to build the app and run the tests. Some tests won't pass on the JDK embedded in Android Studio (JDK8). You might want to set JAVA_HOME and JDK location in Android Studio to JDK11.
7. Go to Tools → AVD Manager and create an emulated device.
8. Run.

Notes:

• To use WordPress.com features (login to WordPress.com, access Reader and Stats, etc) you need a WordPress.com OAuth2 ID and secret. Please read the OAuth2 Authentication section.
• While loading/building the app in Android Studio ignore the prompt to update the gradle plugin version as that will probably introduce build errors. On the other hand, feel free to update if you are planning to work on ensuring the compatibility of the newer version.

OAuth2 Authentication

In order to use WordPress.com functions you will need a client ID and a client secret key. These details will be used to authenticate your application and verify that the API calls being made are valid. You can create an application or view details for your existing applications with our WordPress.com applications manager.

When creating your application, you should select "Native client" for the application type. The "Website URL", "Redirect URLs", and "Javascript Origins" fields are required but not used for the mobile apps. Just use "https://localhost".

Once you've created your application in the applications manager, you'll need to edit the ./gradle.properties file and change the wp.oauth.app_id and wp.oauth.app_secret fields. Then you can compile and run the app on a device or an emulator and try to login with a WordPress.com account. Note that authenticating to WordPress.com via Google is not supported in development builds of the app, only in the official release.

Note that credentials created with our WordPress.com applications manager allow login only and not signup. New accounts must be created using the official app or on the web. Login is restricted to the WordPress.com account with which the credentials were created. In other words, if the credentials were created with [email protected], you will only be able to login with [email protected]. Using another account like [email protected] will cause the Client cannot use "password" grant_type error.

For security reasons, some account-related actions aren't supported for development builds when using a WordPress.com account with 2-factor authentication enabled.

Build and Test

To build, install, and test the project from the command line:

$ ./gradlew assembleWordPressVanillaDebug                        # assemble the debug .apk
$ ./gradlew installWordPressVanillaDebug                         # install the debug .apk if you have an
                                                                 # emulator or an Android device connected
$ ./gradlew :WordPress:testWordPressVanillaDebugUnitTest         # assemble, install and run unit tests
$ ./gradlew :WordPress:connectedWordPressVanillaDebugAndroidTest # assemble, install and run Android tests

Google Configuration

Google Sign-In is only available for WordPress.com accounts through the official app. Contributors can build and run the app without issue, but Google Sign-In will always fail. Google Sign-In requires configuration files which contain client and server information that can't be shared publicly. More documentation and guides can be found on the Google Identity Platform website.
