Starting android calculator programmatically

Here goes:

public static final String CALCULATOR_PACKAGE = 
 "com.android.calculator2";
public static final String CALCULATOR_CLASS = 
 "com.android.calculator2.Calculator";

public static void OpenCalculator(Context context) { 
 Intent i = new Intent();
 i.setAction(Intent.ACTION_MAIN);
 i.addCategory(Intent.CATEGORY_LAUNCHER);

 i.setFlags(
  Intent.FLAG_ACTIVITY_NEW_TASK | 
  Intent.FLAG_ACTIVITY_RESET_TASK_IF_NEEDED);
 i.setComponent(new ComponentName(
  CALCULATOR_PACKAGE, 
  CALCULATOR_CLASS));
 context.startActivity(i);
}
