You can use the GestureOverlayView, if you want to hide the lines it draws you can set the color to Transparent #00000000 so it doesn't show up, and then you can capture all touches, and gestures.

Found this documentation that pretty much states that it's not possible to do both:
<a href="https://stackoverflow.com/questions/8073803/android-multi-touch-and-type-system-overlay">Android : Multi touch and TYPE_SYSTEM_OVERLAY</a>

They discuss workarounds but I don't think any of them will actually work for exactly what I'm trying to do. Both given the events to the underlying app, and being able to snoop them to act upon them for myself.

<blockquote>
 To create an overlay view, when setting up the LayoutParams you need
 to set the type to TYPE_SYSTEM_OVERLAY and use the flag
 FLAG_WATCH_OUTSIDE_TOUCH. This presents a problem because as the
 Android documentation states: "you will not receive the full
 down/move/up gesture, only the location of the first down as an
 ACTION_OUTSIDE." In order to receive the full array of touch events
 you need to use the TYPE_SYSTEM_ALERT type, but this causes the
 overlay to take over the screen and stop interaction with other
 elements.
</blockquote>

Anyone wants to disagree I'd love to hear good news :-D

This is not the optimal solution but it works. Restart the service toggling the flag not touchable. put boolean extra to Intent
which is used to startservice to determine previous state toggle value. A better implementation would be to fire the intent on
touch when the window is listening and after a fixed period when not listening.

<pre class="lang-java prettyprint-override"><code>public class bleh extends Service {
 public void onCteqwer(int i) {

 Context context; Class &lt;bleh&gt; context1 = bleh.class;

 WindowManager.LayoutParams params = null;
 WindowManager mang = (WindowManager) getSystemService(WINDOW_SERVICE);

 //check previous state of service
 if(i==0)
 params = new WindowManager.LayoutParams(arg0,arg1,arg2,arg3,arg4,arg5);

 if(i==1)
 params = new WindowManager.LayoutParams(
 WindowManager.LayoutParams.FLAG_NOT_TOUCHABLE,arg0,arg1,arg2,arg3,arg4);

 LayoutInflater inflater = (LayoutInflater) getSystemService(LAYOUT_INFLATER_SERVICE);
 View mViw = inflater.inflate(arg, null);

 mViw.setOnTouchListener(new OnTouchListener() {
 @Override
 public boolean onTouch(View v, MotionEvent event) {
 return true;
 }
 });

 mang.addView(mViw, params);

 Intent z = new Intent(context, context1);

 if(i==0)
 z.putExtra("name", 1);
 if(i==1)
 z.putExtra("name", 0);

 stopSelf();
 startService(z);
 }

 @Override
 public IBinder onBind(Intent arg0) {
 return null;
 }

 @Override
 public void onStart(Intent intent, int startId) {
 super.onStart(intent, startId);
 Bundle i=intent.getExtras();
 int userName = 0;

 if (i != null)
 {
 userName = i.getInt("name");
 onCteqwer(userName);

I was looking for the same thing.

This flag does the trick for me FLAG_NOT_TOUCH_MODAL

Works on Android 7 and 8 setup as below.

The only action I've implemented so far is a touch to close the overlay window.

I also used code from here <a href="https://github.com/noln/system-alert-window-example" rel="nofollow noreferrer">Example System Overlay Code on Github</a> which was needed to get the events.

By the way Google Maps does a really nice job with this on Android 8. You can drag their overlay window around, resize it or close it. And all other apps work fine while it's up.

<pre><code> var type = 0

 if (Build.VERSION.SDK_INT &lt; Build.VERSION_CODES.O)
 {
 type = WindowManager.LayoutParams.TYPE_SYSTEM_ALERT
 }
 else if (Build.VERSION.SDK_INT &gt;= Build.VERSION_CODES.O)
 {
 type = WindowManager.LayoutParams.TYPE_APPLICATION_OVERLAY
 }

 var flags = FLAG_NOT_TOUCH_MODAL

 mOverlayLayoutParams = WindowManager.LayoutParams(WindowManager.LayoutParams.WRAP_CONTENT, WindowManager.LayoutParams.WRAP_CONTENT, type, flags, PixelFormat.TRANSLUCENT)
</code></pre>

I'm basically trying to get all touch event data from something like a system overlay, move my sprites around based on this touch data, then allow the OS/homescreen/browser to act upon the data as it should(or vice versa). I have found similar questions, but nothing that leads me anywhere I haven't already been:

<a href="https://stackoverflow.com/questions/6742177/getting-the-view-that-is-receiving-all-the-touch-events">Getting the View that is receiving all the touch events</a> 

(Implemented, with results below)
<a href="https://stackoverflow.com/questions/4481226/creating-a-system-overlay-always-on-top-button-in-android">Creating a system overlay window (always on top)</a> 

What I can do:

I can EITHER grab ALL the touch events and act upon them by moving my sprites and not allow the OS/homescreen/browser to see any of them, OR ELSE I can allow the touch events to pass through and only get a “TOUCH_OUTSIDE” for my app to act upon. 

My unattained goal:

I CAN NOT for the life of me figure out a way around getting BOTH to work with the data. The only methods I can think of, that I can't get implemented are:
Intercepting the data in my APP and passing it onto OS/homescreen/browser to work with
Allowing the OS/homescreen/browser to get the data first, and then getting a callback with information somehow
Allowing the OS/homescreen/browser to get the data, act on the data, and the poll them for what their scroll/location values are so as to act upon it in my APP.

I fear that this just isn't possible, I think I read somewhere in some documentation that I can't find now: 
“It's all or nothing, either your view gets all the events, or none of them”

(To avoid confusion, I don't mean I have two views. I mean I have one view controlled via activity/service overlaying the OS/homescreen/browser. Like a pane of glass if you will.)

Thank you for any helpful information you can offer, it's very much appreciated!

[UPDATE]
Posted my own documentation on the matter below, so as to not be confusing.

Android overlay to grab ALL touch, and pass them on?

Android

我基本上是试图从系统覆盖的东西中获取所有的触摸事件数据，基于这些触摸数据移动我的精灵，然后允许OS/homescreen/browser按照它应该的方式操作这些数据(反之亦然)。我也发现了类似的问题，但没有什么能让我找到我没有去过的地方：(已实现，结果如下) 我能做什么：我可以抓取所有的触摸事件并通过移动精灵来处理它们...
