title: Open activity as pop-up and not in other screen in Android?
body: <p>I am working with Bluetooth Chat sample code. In sample app the Device opens up in another screen but I have implemented the same code with the difference that <code>DeviceListActivity</code> is called as soon as the app is started but this opens it in another screen and I want that it should be opened as pop-up in Bluetooth chat sample code.</p>
  
  <p>Can someone let me know how to open Activity as pop-up?</p>
