The method checkSelfPermission(Context, String) is undefined for the type ContextCompat

Question

Context context;

@Override
protected void onCreate(Bundle savedInstanceState) {
    super.onCreate(savedInstanceState);
    setContentView(R.layout.activity_main);
         


        

Answer 1

ContextCompat.checkSelfPermission() requires support library in version 23 or higher.

Add in dependencies block in lower-level build.gradle:

compile 'com.android.support:appcompat-v7:23.1.1' 

If you have previous version here (which you probably have), you should replace lane with provided by me.
