If i change my compileSdk 31 it gives me another error.

Could not resolve all files for configuration ':app:androidApis'.

Solution

Change your compileSdk 30 to 31.

It worked for me!

   compileSdk 31

    defaultConfig {
        applicationId "com.example.lifecycle"
        minSdk 21
        targetSdk 30
        versionCode 1
        versionName "1.0"

        testInstrumentationRunner "androidx.test.runner.AndroidJUnitRunner"
    }

This works for me, First download Android 12 (API 31), then change compileSdk and targetSdk to 31 and sync. It works for me. Thanks
