Question

I am developing ui automation platform for android.

For some reason sometimes (very rare) click events can be dropped

When it happen I see in log

I/InputDispatcher( 2707): Dropped event because input dispatch is disabled.

Please advise what can be done to enable input dispatch.

Thank you in advance

It happened only when screen was off. Click event was turning screen on, but it event was quicker than turning screen on.

Now, I am checking if screen is off and turning it on

//Acquire wake lock in case screen is off
if (PermissionsUtil.checkSelfPermission(getContext(), Manifest.permission.WAKE_LOCK))
{
    PowerManager pm = (PowerManager)getContext().getSystemService(Context.POWER_SERVICE);
    if (pm.isScreenOn() == false)
    {
        wakeLock = pm.newWakeLock((PowerManager.FULL_WAKE_LOCK | PowerManager.ACQUIRE_CAUSES_WAKEUP), TAG);
        // 
        wakeLock.acquire();
        Log.d(TAG,"Acquiring wake lock");
     }
}

//Do my stuff

//Release wake lock in case it was acquire
if (wakeLock != null && wakeLock.isHeld())
{
    wakeLock.release();
    wakeLock = null;
    Log.d(TAG,"Releasing wake lock");
}
