How to start an Intent from a ResolveInfo

Question

I'm trying to make a custom launcher for android, and I'm trying to figure out how to launch a different application form mine. I figured the way to do it was intents, and I've found a post on it here:

Open another application from your own (intent)

I don't really understand the answer though! Can someone give me a concise snippet or series of steps to go from a single ResolveInfo to launching the app represented by that ResolveInfo?

Answer 1

Given a ResolveInfo named launchable:

ActivityInfo activity=launchable.activityInfo; ComponentName name=new ComponentName(activity.applicationInfo.packageName,                                      activity.name); Intent i=new Intent(Intent.ACTION_MAIN);  i.addCategory(Intent.CATEGORY_LAUNCHER); i.setFlags(Intent.FLAG_ACTIVITY_NEW_TASK |             Intent.FLAG_ACTIVITY_RESET_TASK_IF_NEEDED); i.setComponent(name);  startActivity(i);
