docs: Change the operating mode for the given op in the given app package. You must pass in both the
  uid and name of the application whose mode is being modified; if these do not match, the
  modification will not be applied.
  
  <p>This method is public for testing {@link #checkOpNoThrow}. If {@link #checkOpNoThrow} is
  called afterwards with the {@code op}, {@code ui}, and {@code packageName} provided, it will
  return the {@code mode} set here.
  
  @param op The operation to modify. One of the OPSTR_* constants.
  @param uid The user id of the application whose mode will be changed.
  @param packageName The name of the application package name whose mode will be changed.
