Now, if you want to prevent this action for your application or any activity, then you just need a few lines of code in your activity. You can use FLAG_SECURE, and then the Notification will be "Can’t take screenshot…….". There is no application level protection. You have to add this code in all the activities that you want to protect.

You just need to add this line in the activity:

getWindow().setFlags(WindowManager.LayoutParams.FLAG_SECURE,
				WindowManager.LayoutParams.FLAG_SECURE);

FLAG_SECURE Indicates that the display has a secure video output and supports compositing secure surfaces. Secure surfaces are used to prevent content rendered into those surfaces by applications from appearing in screenshots or from being viewed on non-secure displays. Protected buffers are used by secure video decoders for a similar purpose.

This method required to import WindowManager class. After adding this class in your code for the prevents screen capture will be finished, you can see this example:

package com.legendblogs.demo;
import android.content.Context;
import android.support.v7.app.AppCompatActivity;
import android.os.Bundle;
import android.view.WindowManager;
public class MainActivity extends AppCompatActivity {
    @Override
    protected void onCreate(Bundle savedInstanceState) {
        super.onCreate(savedInstanceState);
        setContentView(R.layout.activity_main);
        getWindow().setFlags(WindowManager.LayoutParams.FLAG_SECURE,
				WindowManager.LayoutParams.FLAG_SECURE);
    }
}
