You need a context to call getPackageManager() on it. Get the context from an activity in your app:

in onCreate block of your main activity:

AppLauncher.setContext(this.getBaseContext));

in your Non-Activity Class (AppLauncher):

Context context;
public static void setContext(Context context) {
    this.context = context;
}

in your Non-Activity Class where you want to call getPackageManager():

context.getPackageManager();

Tip: if you are developing in eclipse on windows, always use Ctrl+Shift+O to automatically import missing and required packages.

Those methods (such as getPackageManager() or startActivity()) are members of a context. You need to pass either your main activity or its Context to the other class.

BTW I don't get why you need package manager to launch another application. What about calling startActivity() with the corresponding intent ? (but I guess there are good reasons for doing it your way)

Pass your activity context to non-activity class. And from that context call the different application.
