Answer 1

The minCompileSdk (31) specified in a dependency's AAR metadata (META-INF/com/android/build/gradle/aar-metadata.properties) is greater than this module's compileSdkVersion (android-30). Dependency: androidx.appcompat:appcompat:1.4.0

The solution is in the error itself. There can be two solutions:

1. Use Android SDK version 31 in your project. Find compileSdkVersion 30 in your app\build.gradle file, and change it to compileSdkVersion 31.
2. Force gradle to use an older version of the dependency androidx.lifecycle:lifecycle-process:2.4.0. If you are not directly using this dependency, force gradle to use an older version like this:

android {
  defaultConfig {
       configurations.all {
          resolutionStrategy { 
            force 'androidx.lifecycle:lifecycle process:2.3.1'
            force 'androidx.appcompat:appcompat:1.3.1'
            force 'androidx.appcompat:appcompat-resources:1.3.1'  
            // force 'androidx.emoji2:emoji2-views-helper:1.0.0', This won't work, because it is made to work with Android SDK version 31 only
            force 'androidx.core:core:1.6.0'        
            force 'androidx.lifecycle:lifecycle-runtime:2.3.1'
         }
      }
   }
}

Force older versions of other dependencies causing errors like this only.

Follow only one out of these two steps

Look at the error message near what went wrong find "AAR metadata file: " copy the location and paste it on file explorer

manually change the minCompileSdk=31 to 30 save
