if(getPackageManager().hasSystemFeature(PackageManager.FEATURE_TOUCHSCREEN_MULTITOUCH)) {
        Toast.makeText(this, "support multitouch", Toast.LENGTH_SHORT).show();
    findViewById(R.id.cl_main).setOnTouchListener(new View.OnTouchListener() {
        @Override
        public boolean onTouch(View v, MotionEvent event) {
                int pointerCount = event.getPointerCount();
                Toast.makeText(FirstActivity.this, "number of fingers " + pointerCount, Toast.LENGTH_SHORT).show();
            return true;
        }
    });
}

if (getPackageManager().hasSystemFeature(PackageManager.FEATURE_TOUCHSCREEN_MULTITOUCH_JAZZHAND)) {
        Toast.makeText(this, "More than 5 fingers", Toast.LENGTH_SHORT).show();
    }
