    The issue was that the “HelperActivity” was being allowed to have the Component set to 0, and it will cause the app to error when the user tries to open the app from the market, or from the app drawer. Also having the APEX intent, in the helper activity, was removing the Apex compatibility when the “HelperActivity” activity was no longer accessible.

    This thread is now answered.

    For a more suitable substitute, you would want to use the SET_COMPONENT_ENABLED flags with “KILL_APP” flags not enabled, but thats another situation all together.
