Exception not properly handled in Android intent to uninstall package

The following code will uninstall a package on a device if I pass in a package name that exists on the phone. 

public static String Execute(Context myContext, String packageName){

        Intent intent = new Intent(Intent.ACTION_DELETE);
        intent.addFlags(Intent.FLAG_ACTIVITY_NEW_TASK); 
        try{
            intent.setData(Uri.parse("package:" + packageName));
            myContext.startActivity(intent);
        }catch(Exception e){
            System.out.println("package " + packageName + " not installed");
            return "Package was not uninstalled";
        }

        return "Package " + packageName + " uninstalled.";
    }

However if I pass in a package name that isn't on the phone, my exception isn't handled and I get an error that says

"Invalid packageName or componentName in [packageName]"

stack trace

and then the return statement "Package [packageName] uninstalled" is returned. What's wrong with my exception handling here? I want the code within the catch statement to be executed/returned if that error occurs, but it's not working.

my exception isn't handled

That is because it is not an exception and is not coming from your process.

Nothing, other than it not being effective for this case.

Use PackageManager to see if the package exists before attempting to delete it.
