Here is a sample code to disable pull notifications by using custom overlay. It works fine on Android versions below and 6+.
Permissions Required in Manifest:
<uses-permission android:name="android.permission.ACTION_MANAGE_OVERLAY_PERMISSION" />
<uses-permission android:name="android.permission.SYSTEM_ALERT_WINDOW" />
Disabling the pull notifications
private void disablePullNotificationTouch() {
try {
Log.v("App", "Disable Pull Notification");
private HUDView mView = new HUDView(this);
int statusBarHeight = (int) Math.ceil(25 * getResources().getDisplayMetrics().density);
Log.v("App", "" + statusBarHeight);
WindowManager.LayoutParams params = new WindowManager.LayoutParams(
WindowManager.LayoutParams.MATCH_PARENT,
statusBarHeight,
WindowManager.LayoutParams.TYPE_SYSTEM_ERROR,
WindowManager.LayoutParams.FLAG_NOT_FOCUSABLE |
WindowManager.LayoutParams.FLAG_LAYOUT_IN_SCREEN, //Disables status bar
PixelFormat.TRANSPARENT); //Transparent
params.gravity = Gravity.CENTER | Gravity.TOP;
WindowManager wm = (WindowManager) getSystemService(WINDOW_SERVICE);
wm.addView(mView, params);
} catch (Exception e) {
Log.v("App", "Exception: " + e.getMessage());
}
}
// code to post/handler request for permission
public final static int REQUEST_CODE = -1010101;
@RequiresApi(api = Build.VERSION_CODES.M)
public void checkDrawOverlayPermission() {
Log.v("App", "Package Name: " + getApplicationContext().getPackageName());
// check if we already have permission to draw over other apps
if (!Settings.canDrawOverlays(context)) {
Log.v("App", "Requesting Permission" + Settings.canDrawOverlays(context));
// if not construct intent to request permission
Intent intent = new Intent(Settings.ACTION_MANAGE_OVERLAY_PERMISSION,
Uri.parse("package:" + getApplicationContext().getPackageName()));
/ request permission via start activity for result
startActivityForResult(intent, REQUEST_CODE);
} else {
Log.v("App", "We already have permission for it.");
disablePullNotificationTouch();
}
}
@TargetApi(Build.VERSION_CODES.M)
@Override
protected void onActivityResult(int requestCode, int resultCode, Intent data) {
Log.v("App", "OnActivity Result.");
//check if received result code
// is equal our requested code for draw permission
if (requestCode == REQUEST_CODE) {
if (Build.VERSION.SDK_INT >= Build.VERSION_CODES.M) {
if (Settings.canDrawOverlays(this)) {
disablePullNotificationTouch();
}
}
}
}
Your code after modifications
public class MainActivity extends Activity {

//No need for Permission as less then M OS.
}

}
}
@TargetApi(Build.VERSION_CODES.M)

}
public boolean CheckPermission(Context context, String Permission) {

startActivityForResult will call onActivityResult if you call this from an activity and not from service. Read more about it here
