How to get a list of installed android applications and pick one to run

I asked a similar question to this earlier this week but I'm still not understanding how to get a list of all installed applications and then pick one to run.

I've tried:

Intent intent = new Intent(ACTION_MAIN);
intent.addCategory(CATEGORY_LAUNCHER);


and this only shows application that are preinstalled or can run the ACTION_MAIN Intent type.

I also know I can use PackageManager to get all the installed applications, but how do I use this to run a specific application?

Answer

Following is the code to get the list of activities/applications installed on Android :

final Intent mainIntent = new Intent(Intent.ACTION_MAIN, null);
mainIntent.addCategory(Intent.CATEGORY_LAUNCHER);
final List pkgAppsList = context.getPackageManager().queryIntentActivities( mainIntent, 0);

You will get all the necessary data in the ResolveInfo to start a application. You can check ResolveInfo javadoc here.

HTH !
