Setup

Installing APK via GitHub Releases

This is the recommended installation option.

1. On the right-hand side of the GitHub page for ControlX2, select "Releases"
2. Under the most recent release, download the mobile-release.apk file for the phone application, and optional wear-release.apk file for the Wear OS application.
3. Install the APK file on your device(s).

Installing APK via GitHub Actions

1. Open this link to view the most recent GitHub Actions runs to the main branch.
2. Select the most recent entry from the list.
3. Download the mobile-release.apk file for the phone application, and optional wear-release.apk file for the Wear OS application.

4. Install the APK file on your device(s).

Building from source

Clone the repo, open in Android Studio, and build the module for:

• mobile - Android phone application
• wear - Android Wear OS application

Enable ADB debugging on your phone or watch and then select "Run" using the correct module:

Building with local PumpX2

Clone the PumpX2 repository and publish it to the local Maven repository. You can do this with:

$ git clone https://github.com/jwoglom/pumpx2
$ cd pumpx2
$ ./gradlew build
$ ./gradlew publishToMavenLocal 

The PumpX2 library files will be published to $HOME/.m2/repository/com/jwoglom/pumpx2/.

Then, set the use_local_pumpx2 Gradle property true in either your command-line execution with ./gradlew build -Duse_local_pumpx2=true, or edit your local.properties file for it to be reflected in Android Studio.

If the PumpX2 libraries are rebuilt, either bump the version number in both PumpX2 and ControlX2's gradle configurations or run ./gradlew build --refresh-dependencies in ControlX2. Otherwise, if the version number was not bumped, rebuilding ControlX2 may still use a cached version of the old code from that version.
