title: Android Marking an application installed
body: <p>I have a question for you: i have an application where some apks could be downloaded and installed. 
  I launch installation in this way:</p>
  
  <blockquote>
    <p>Intent myIntent = new Intent();<br>
                    myIntent.setAction(android.content.Intent.ACTION_VIEW);<br>
                    myIntent.setDataAndType(Uri.parse("file://" + getFilesDir() + "/" + m_sLastFileName ), "application/vnd.android.package-archive");<br>
                    startActivity(myIntent);</p>
  </blockquote>
  
  <p>Now i have this problem: i want to know which apks the user has installed, so the question is: can i mark the installed applications in a way that i can recognise them as "My App"?
  Or can you suggest me an alternative solution?</p>
  
  <p>thanks.</p>
