title: Android windowManger remove flags
body: <p>I have a <code>WindowManger</code> in a Service and I add some flags:</p>
  
  <pre><code>params = new WindowManager.LayoutParams(
      WindowManager.LayoutParams.MATCH_PARENT,
      WindowManager.LayoutParams.WRAP_CONTENT,
      WindowManager.LayoutParams.TYPE_PHONE,
      WindowManager.LayoutParams.FLAG_NOT_FOCUSABLE|WindowManager.LayoutParams.FLAG_NOT_TOUCHABLE,
      PixelFormat.TRANSLUCENT);
  
      params.gravity = Gravity.TOP | Gravity.LEFT;
  
      params.y = 0; //topPadding
      params.x = 0;
      windowManager.updateViewLayout(view, params);
  </code></pre>
  
  <p>How can I remove <code>WindowManager.LayoutParams.FLAG_NOT_TOUCHABLE</code> later in another part?</p>
