Download app if intent not installed

Question

I know I have seen a way of calling an Intent, and if it doesn\'t exist the function will redirect to market for download the application that has the intent.

Right

Answer 1

To check if some Intent is available:

String intentToCheck = "com.google.SCAN"; //can be any other intent
final PackageManager packageManager = getPackageManager();
final Intent intent = new Intent(intentToCheck);
List list = packageManager.queryIntentActivities(intent, PackageManager.MATCH_DEFAULT_ONLY);
final boolean isAvailable = list.size() > 0;

To open Google Market via Intent:

Intent marketIntent = new Intent(Intent.ACTION_VIEW, Uri.parse("market://search?q=pname:com.google.scan"));
startActivity(marketIntent); 

Answer 2

I haven't done this before but in theory it is just another Intent call with a view flag and the market://... URI pointing to the application.
