Get pointer absolute position

[BHznJNs]

I am trying to add a new function for the scrcpy-server, to get the absolute position of pointer.

I tried some ways:

• getevent: with getevent command, i can only get the relative movement of cursor
  • i also tried to calculate the absolute position by relative movement integral, but there is always some error so i think this approach might not be feasible.
• startActivityAsUser: i noticed that the scrcpy.wrappers.ActivityManager has a method startActivity, which calls the startActivityAsUser method. I tried to use it to create an activity from an activity class or a package name, but it seems i has no permission to do so.

Would there be any way to implement that? Thank you so much!

Maybe i found a possible way: change the HID_MOUSE_REPORT_DESC so that i can send the absolute position of mouse to server to move mouse

After some trial, the way to change the HID_MOUSE_REPORT_DESC seems not work.
I do not sure if the HID report decription is wrong or the HID input data writing is wrong, and
I also searched a forum posts that says, the android does not support the absolute positioning HID mouse
