## Build Instructions


1. Clone or Download the repository:

  ```shell
  git clone https://github.com/mozilla-mobile/focus-android
  ```

2. Import the project into Android Studio **or** build on the command line:

  ```shell
  ./gradlew clean app:assembleFocusDebug
  ```

3. Make sure to select the correct build variant in Android Studio:
**focusArmDebug** for ARM
**focusX86Debug** for X86
**focusAarch64Debug** for ARM64

## local.properties helpers
You can speed up or enhance local development by setting a few helper flags available in `local.properties` which will be made easily available as gradle properties.

### Building debuggable release variants

Nightly, Beta and Release variants are getting published to Google Play and therefore are not debuggable. To locally create debuggable builds of those variants, add the following to `<proj-root>/local.properties`:

```sh
debuggable
```

### Auto-publication workflow for application-services and glean
If you're making changes to these projects and want to test them in Focus, auto-publication workflow is the fastest, most reliable
way to do that.

In `local.properties`, specify a relative path to your local `glean` and/or `application-services` projects. E.g.:
- `autoPublish.glean.dir=../glean`
- `autoPublish.application-services.dir=../application-services`

Once these flags are set, your Focus builds will include any local modifications present in these projects.

See a [demo of auto-publication workflow in action](https://www.youtube.com/watch?v=qZKlBzVvQGc).

## Pre-push hooks
To reduce review turn-around time, we'd like all pushes to run tests locally. We'd
recommend you use our provided pre-push hook in `quality/pre-push-recommended.sh`.
Using this hook will guarantee your hook gets updated as the repository changes.
This hook tries to run as much as possible without taking too much time.

To add it, run this command from the project root:
```sh
ln -s ../../quality/pre-push-recommended.sh .git/hooks/pre-push
```

To push without running the pre-push hook (e.g. doc updates):
```sh
git push <remote> --no-verify
```

## Test Channel on Google PlayStore
To get Focus Nightly on your device, follow these steps:

1) Visit https://groups.google.com/g/firefox-focus-pre-release and join the Google Group
2) After you have joined the group opt-in to receive Nightly builds, again with the same Google account: https://play.google.com/apps/testing/org.mozilla.focus.nightly
3) Download Firefox Focus (Nightly) from Google Play: https://play.google.com/store/apps/details?id=org.mozilla.focus.nightly

Make sure you use the same Google Account for both steps.
