Question

I am trying to create program that simply opens file on sdcard. I tried opening mp3, mp4, and apk – the code bellow always crashes unexpectedly.

  String _path = "file:///sdcard/1.apk";

     Uri outputFileUri = Uri.parse(_path);
    Intent intent = new Intent();
    intent.setAction(Intent.ACTION_VIEW);

Market links also crashes. But when I set _path=”http://google.com” – browser opens normally. How can I make this code work?

If you’re trying to install the apk, you need to use the following:

String fileName = Environment.getExternalStorageDirectory() + "/1.apk";
Intent intent = new Intent(Intent.ACTION_VIEW);
intent.setDataAndType(Uri.fromFile(new File(fileName)), "application/vnd.android.package-archive");
startActivity(intent);

If you’re trying to launch the app (after installing), then:

Intent intent = new Intent();
intent.setClassName("com.pkg.addr", "com.pkg.addr.MainActivity");
startActivity(intent);

If you’re trying to launch a player to play the mp3 file:

Intent intent = new Intent(android.content.Intent.ACTION_VIEW);
Uri data = Uri.parse("file:///sdcard/1.mp3");
intent.setDataAndType(data,"audio/mp3");
startActivity(intent); 

Hope that helps.
