to recreate this issue, update your project level gradle to as:

classpath 'com.android.tools.build:gradle:4.1.3'

and update your app level gradle as

implementation fileTree(dir: 'libs', include: ['*.jar']) implementation "org.jetbrains.kotlin:kotlin-stdlib-jdk7:1.4.10" implementation 'androidx.appcompat:appcompat:1.2.0' implementation 'androidx.core:core-ktx:1.3.2' implementation 'androidx.constraintlayout:constraintlayout:2.0.4' testImplementation 'junit:junit:4.13.2' androidTestImplementation 'androidx.test.ext:junit:1.1.2' androidTestImplementation 'androidx.test.espresso:espresso-core:3.3.0' implementation 'de.hdodenhof:circleimageview:3.1.0' // implementation project(':mlselfiecamera') implementation 'net.fitken:mlselfiecamera:0.1.2'

Hi @tahirghani9,

Thank you for using my small library. Currently, I'm too busy to check on this. I think you can add the library as a module like above ("mlselfiecamera") and then you can modify it to make it work.

Thank you again. I'll look into this when I have time.
