Great God seeking advice! Urgent!

[Align = left] I want to be a reminder alarm clock, set the time to start the service in EssayActivity, gets the system time, the two are equal the alarm. But the service has been wrong (abnormal) Calling a method in the system process without a qualified user: android.app.ContextImpl.sendBroadcast: 1140 android.content.ContextWrapper.sendBroadcast: 345 com.android.settings.batterywarning.ReadCodeTask.sendWarningMessage : 59 com.android.settings.batterywarning.ReadCodeTask.run: 41 java.util.Timer $ TimerImpl.run: 284
Debugging has been off from timer.scheduleAtFixedRate (new TimerTask () {Skip to end}, 0,1000 * 60);
Attach the source code line and plane, the ball great God enlighten!
