onclick - Use same method for all option menu in whole Application Android

Question

I have 10 to 12 Activity, All Activity has Help Menu as an Option Menu. I am succeed with following code to create it and showing help on click of them.

    Intent intent = new Intent();
    intent.addFlags(Intent.FLAG_ACTIVITY_NEW_TASK);
    intent.setAction(Intent.ACTION_VIEW);
    intent.setDataAndType(Uri.fromFile(new File(cacheDir, "HELP.pdf")),"application/pdf");

    context.startActivity(intent);

But I want to Reduce this code for all Activity, and for that i have created one class and make one method but still i want to reduce code.

I have searched and found that onClick attribute is available in OptionMenu but I didn't get how to use it.

Please Help..

Create a class, for example call it Helper, where you put a method called handleMenu(int id) and where you do all the work. Then, in every activity you call that method from onOptionsItemSelected(), passing the id of the item selected.
