Can't use setForeground method on ImageView [duplicate]

Answer 1

You can either change

minSdkVersion 16

with

minSdkVersion 23

or import android.support.annotation.RequiresApi;
to your class and this statement

@RequiresApi(api = Build.VERSION_CODES.M)

to the activity you used setForground method in it.

Note that M in @RequiresApi(api = Build.VERSION_CODES.M) stands for API 23

and you can use each one of the items below that each one stand for a specific API instead of M
