Android YouTube app Play Video Intent

Question

I m working on a app where you can download YouTube videos for android. Now, I want if you play a video in the YouTube  app you can download it too. To do this, I need to know the Intent that the YouTube  app puts out in order to play the YouTube app.
my question is:
1. Can I download the YouTube app for my emulator, or...
2. What is the intent used when the user selects a video for playback.

Answer 1

The best way to run videos on a different app is by first trying to resolve the package, so something like this:

public void playVideo(String key){

    Intent intent = new Intent(Intent.ACTION_VIEW, Uri.parse("vnd.youtube:" + key));

    // Check if the youtube app exists on the device
    if (intent.resolveActivity(getPackageManager()) == null) {
        // If the youtube app doesn't exist, then use the browser
        intent = new Intent(Intent.ACTION_VIEW,
                Uri.parse("http://www.youtube.com/watch?v=" + key));
    }

    startActivity(intent);
}
