Error while using PackageManager in Android

Question

I got a problem in one Android Application which I am working in which I am getting error when I use PackageManager.

The Application is as follows:

Home.j

Answer 1

try this::

this.getPackageManager().getApplicationInfo(this.getPackageName(), 0);

Answer 2

Result doesn't extend Context like your Activity class does. So the method isn't available in that class. You need to call act.getPackageManager() inside there instead of this.getPackageManager().
