My windowManager code:

windowManager = (WindowManager) this.getSystemService(BackgroundVideoRecorder.WINDOW_SERVICE);
            surfaceView = new SurfaceView(this);
            LayoutParams layoutParams = new WindowManager.LayoutParams(
                1, 1,
                WindowManager.LayoutParams.TYPE_SYSTEM_OVERLAY,
                WindowManager.LayoutParams.FLAG_WATCH_OUTSIDE_TOUCH,
                PixelFormat.TRANSLUCENT
            );
            //layoutParams.gravity = Gravity.LEFT | Gravity.TOP;
            windowManager.addView(surfaceView, layoutParams);
            surfaceView.getHolder().addCallback(this);

Please help me.Thanks in advance.

Problem: Permission missing in maifest file.

Solution: Use following permission in AndroidManifest.

android.permission.SYSTEM_ALERT_WINDOW

    @MBH, maybe add permissions during runtime? http://stackoverflow.com/questions/7569937/unable-to-add-window-android-view-viewrootw44da9bc0-permission-denied-for-t – CoolMind Mar 10 '16 at 09:28
  • yup permissions has to be handled at runtime for marshmallow. This answer was posted for pre-marshmallow. Will update my answer in sometime. – Ritesh Gune Mar 15 '16 at 05:23
  • With marshmallo this issue persists. So to avoid please see the link http://stackoverflow.com/questions/7569937/unable-to-add-window-android-view-viewrootw44da9bc0-permission-denied-for-t#answer-34061521 – rajeesh Apr 28 '16 at 09:24
  • here is the latest working answer https://stackoverflow.com/questions/46208897/android-permission-denied-for-window-type-2038-using-type-application-overlay – Muhammad Natiq Dec 16 '18 at 17:44

if your application apiLevel >= 19, don't use

WindowManager.LayoutParams.TYPE_PHONE or WindowManager.LayoutParams.TYPE_SYSTEM_ALERT

you can use

LayoutParams.TYPE_TOAST

or

TYPE_APPLICATION_PANEL

now my code for LayoutParams is like,

WindowManager.LayoutParams params = new WindowManager.LayoutParams(
            WindowManager.LayoutParams.WRAP_CONTENT,
            WindowManager.LayoutParams.WRAP_CONTENT,
            WindowManager.LayoutParams.TYPE_TOAST,
            WindowManager.LayoutParams.FLAG_NOT_FOCUSABLE,
            PixelFormat.TRANSLUCENT);

    for Lollipop and lower I used WindowManager.LayoutParams.TYPE_PHONE, but It didn't work for Android M, then I used WindowManager.LayoutParams.TYPE_TOAST as you suggested and it works now, thanks! – Mu Sa Aug 08 '16 at 09:20

    Yes, `TYPE_TOAST` works when you are not using to draw on lockscreen – Hitesh Chavda Sep 14 '16 at 04:39
  • I have to use `android.permission.SYSTEM_ALERT_WINDOW` ? – t0m Feb 21 '17 at 12:30
  • 1
    t0m: if you use the TYPE_TOAST, no permission needed – Arkady Apr 27 '17 at 13:14
  • `LayoutParams.TYPE_TOAST` is deprecated from API 26. Use `LayoutParams.TYPE_APPLICATION_OVERLAY` instead and it is requires `android.Manifest.permission#SYSTEM_ALERT_WINDOW` permission => [See more](https://developer.android.com/reference/android/view/WindowManager.LayoutParams.html#TYPE_TOAST) – t0m Jan 04 '18 at 14:32
  • I get `android.view.WindowManager$BadTokenException: Unable to add window -- token null is not valid; is your activity running?` when using `WindowManager.LayoutParams.TYPE_TOAST` instead of `WindowManager.LayoutParams.TYPE_SYSTEM_OVERLAY` on Pixel emulator API 25, though it works ok for Android 23 emulator, weird... – user924 Apr 30 '23 at 10:29

Starting from marshmallow versions the permission approval is a little bit complex. So even after giving the above permission this issue is not resolved. Please see the following link.

Unable to add window android.view.ViewRoot$W@44da9bc0 -- permission denied for this window type
