You can distribute builds to testers using the Firebase CLI. The CLI tool lets you specify testers and release notes for a build, and distributes the build accordingly.
Before you begin
If you haven't already, add Firebase to your Android project.
If you aren't using any other Firebase products, you only have to create a project and register your app. However, if you decide to use additional products in the future, be sure to complete all of the steps on the page linked above.
1. Build your app
When you're ready to distribute a pre-release version of your app to testers, build an APK using your normal process. You must sign the APK with your debug key or app signing key.
2. Distribute your app to testers
To distribute your app to testers, upload the APK file using the Firebase CLI:
- Install or update to the latest version of the Firebase CLI (we recommend downloading the standalone binary for the CLI specific to your OS). Make sure to sign in and test that you can access your projects.
- In the App Distribution page of the Firebase console, select the app you want to distribute, then click Get started.
appdistribution:distributecommand to make the build available to testers. Use the following parameters to configure the distribution:
Required: Your app's Firebase App ID. You can find the App ID in the Firebase console, on the General Settings page.
Release notes for this build.
You can either specify the release notes directly:
--release-notes "Text of release notes"
Or, specify the path to a plain text file:
The email addresses of the testers you want to invite.
You can specify the testers as a comma-separated list of email addresses:
--testers "email@example.com, firstname.lastname@example.org, email@example.com"
Or, you can specify the path to a plain text file containing a comma-separated list of email addresses:
The tester groups you want to invite (refer to Manage testers). Groups are specified using
group aliases, which you can look up in the Firebase console.
You can specify the groups as a comma-separated list:
--groups "qa-team, trusted-testers"
Or, you can specify the path to a plain text file containing a comma-separated list of group names:
A flag you can include to print verbose log output.
firebase appdistribution:distribute test.apk \ --app 1:1234567890:android:0a1b2c3d4e5f67890 \ --release-notes "Bug fixes and improvements" --testers-file testers.txt
Testers who haven't been invited to test the app receive email invitations to get started. Existing testers receive email notifications that a new build is ready to test.
After you distribute a new build, you can monitor the status of each tester—whether they accepted the invitation and whether they downloaded the app—in the Firebase console.
