- Include a notice releasing the code under an open-source license. If you haven’t already chosen one, we recommend the MIT License.
Once you’ve done that, please contact us to request a license key, giving the following information:
- Where the app’s source code is available.
- The application ID from your
build.gradlefile. This should be something unique to yourself, not a generic value like

Activating a license
Once you have a license key, activate it by adding the following line to the project’s
The notification and time limit will then be removed the next time you build your app.
