问题 I am in the process of trying to get an email sent using BroadcastReceiver, the code is working correct using AsyncTask when using onClick but does not work when AlarmReceiver is being called.

It loads some settings and does some stuff in the background (it's a productivity tool/utility). This IntentService , when loading my, let's call it "stuff" , decides whether or not to add some alarms via AlarmManager .
