This is a Gradle project, and can be built via the provided gradlew or by using Android Studio.

1. Open the project in the IDE.

   1. From the "Welcome to Android Studio" menu, select "Open an existing Android Studio project" option, or
   2. If you already have an opened project, select "File > Open..."

2. If you want to test Google sign in, add the required metadata:

   1. Go to https://developers.google.com/mobile/add?platform=android

   2. Type in "Zulip" as "App name" and "com.zulip.android" as "Android package name".)

   3. Put the generated file in the "app/" directory of the project.

   4. Google app id. You will also get it from the above given link. This id should be written as the following string resource in app/src/main/res/values/strings.xml:

      <string name="google_app_id">GOOGLE_APP_ID</string>
      

If you have a device running Android go to the settings and enable USB debugging in developer options. Then plug your device in the computer and select "Run > Run...". You will be shown "Device chooser" window. Select your device in the given list and press "OK".

If you do not have an Android device you will have to run it on an emulator. Here are instructions for creating an Android virtual device (AVD):

1. Install the Android SDK including at least the API 23 (Android 6.0), Build Tools, API Platform, Google APIs, Google Play Services, Android Support Library, the Local Maven Repository for Support and the Google Repository.

   All of these can be installed, together with their dependencies, using the Android SDK manager.

2. Comment out or remove references to Crashlytics. The following are known references as at 5de0b0e. For future versions, grep -ir crashlytics . is your friend.

   If you do not remove Crashlytics then the app will crash on startup unless Crashlytics has been set up correctly as a member of the zulip team.

• In app/src/main/java/com/zulip/android/ZLog.java:
  • Line 5: import com.crashlytics.android.Crashlytics;
  • Line 13: Crashlytics.logException(e);
• In app/src/main/java/com/zulip/android/ZulipActivity.java:
  • Line 50: import com.crashlytics.android.Crashlytics;
  • Line 162: Crashlytics.start(this);

3. Run ./gradlew (or gradlew.bat on Windows). This should automatically build the application, downloading anything it needs to do so.

   If you get a failed build with A problem occurred configuring project ':app'. then you might not have all the required SDK libraries. Make sure that you have all the dependencies of the libraries listed above, and that all versions match precisely.

   If the appropriate tools cannot be found by gradle, make sure that ANDROID_HOME is properly set (this should point to the root directory for the Android SDK i.e. the one which contains the add-ons, build-tools, docs and other directories).

4. To build the APK, run ./gradlew assemble. Your APKs will be placed in app/build/outputs/apk.

   The app-debug.apk can be installed directly on the device, or loaded over USB using ./gradlew installDebug or adb install /path/to/app/build/outputs/apk/app-debug.apk.

   Note that app-release-unsigned.apk will not install by default because it is unsigned. You will be told the APK cannot be parsed.
