title: Android start intent to view apk
body: <p>In my application I am downloading and saving an apk to the SDcard and then I want to start the installation of the apk. I'm using the following code to attempt this:</p>
  
  <pre><code>Intent intent =new Intent();
  intent.setAction(Intent.ACTION_VIEW);
  intent.setDataAndType(Uri.parse(file), "application/vnd.android.package-archive");
  activity.startActivity(intent);
  </code></pre>
  
  <p>But when I do this it tells me there is no activity to start the intent. What I am attempting to do is install a new update for the currently running application. How do I start an Intent to run an apk file?</p>
