  • When start building the app, pick the template “Empty View Activity” (Java) instead of “Blank Activity” (Kotlin).

  • If you encounter the following problem:
    An issue was found when checking AAR metadata: 1. Dependency 'androidx.activity:activity:1.10.0' requires libraries and applications that depend on it to compile against version 34 or later of the Android APIs. :app is currently compiled against android-33...
    replace the following command in the gradle file: 
       implementation("com.google.android.material:material:1.10.0")
    by 
       implementation("com.google.android.material:material:1.10.0")
