Forks

Forks are allowed so long as they abide by the project's LICENSE.

When creating a fork, remember to:

• To avoid confusion with the main app:
  • Change the app name
  • Change the app icon
  • Change or disable the app update checker
• To avoid installation conflicts:
  • Change the applicationId in build.gradle.kts
• To avoid having your data polluting the main app's analytics and crash report services:
  • If you want to use Firebase analytics, replace google-services.json with your own
  • If you want to use ACRA crash reporting, replace the ACRA_URI endpoint in build.gradle.kts with your own
