How to Send Mouse Movements and Clicks from Android to Desktop

I want to make an app (Android Studio and Java) that can control a desktop mouse cursor via Bluetooth.

How would I go about doing this? Are there any functions to control the cursor of a device connected via BT? Thanks in advance!

It is a late answer but one solution would be designing the architecture like:

  • An application that is capable of reading the touch input using the MotionEvent.ACTION_MOVE and recording the previous and current values and computing the difference sending it through a bluetooth UDP client to a server. 

    @Override
public boolean onTouch(MotionEvent e)
{

   switch(e)
   {     
        case MotionEvent.ACTION_DOWN:
            float initX = e.getX();        
            float initY = e.getY();
            return true;

        case MotionEvent.ACTION_MOVE:        
            float curX = initX - e.getX();
            float curY = initY - e.getY();
            sendThroughUDP(curX, curY);
            return true; 
    }
}

  • A Server running on your desktop capable of reading this. For example a simple java UDP server over bluetooth which is possible as given here. This will receive these values and then inject these values to the Robot class if Java. 

 //implement the UDP over the bluetooth stack.
 public static void main(String [] args)
 {
      UDPOverBluetoothServer UDPBT = new UDPOverBluetoothSever(socketInformation);
      int xValue = UDPBT.getX();          
      int yValue = UDPBT.getY();
      Robot robot = new Robot();
      Point mousePointer = MouseInfo.getPointerInfo().getLocation();
      robot.mouseMove(mousePointer.x - xValue, mousePointer.y - yValue); 
 }
