Android - Error when i'm trying to apply a custom layout on Navigation Drawers


The problem is that you are trying to fetch resources in the initializer of your fragment's sidebar_items array:

private String[] sidebar_items = {
    getString(R.string.title_drawer1),
getString(R.string.title_drawer2), 
    getString(R.string.title_drawer3),
getString(R.string.title_drawer4)};

The call to getString requires that the Fragment is already attached to an Activity. However, that doesn't happen until later.

You have a two options:

  1. Convert sidebar_items into an int array, like sidebar_images_on, and call getString when you access the array.
  2. Override onAttach(Activity) in your Fragment, and initialize sidebar_items there.
