Androidmanifest.xml integration failed
my solution is:
build.gradle in the app

android {
    compileSdkVersion 30

    defaultConfig {
        minSdkVersion 21
        targetSdkVersion 30
        versionCode 202
   }
}

Build.gradle in the module, plus buildtoolsversion “29.0.0”

android {
    compileSdkVersion 29
    buildToolsVersion "29.0.0"

    defaultConfig {
        minSdkVersion 21
        targetSdkVersion 29
        versionCode 1
        versionName "1.0"
   }
}
