}
public void CancelAnAlarm(int id){
AlarmManager am = (AlarmManager) getApplicationContext().getSystemService(getApplicationContext().ALARM_SERVICE);
Intent i = new Intent(getApplicationContext(), SendSMSAlarmService.class);
PendingIntent pi = PendingIntent.getService(getApplicationContext(), id, i, PendingIntent.FLAG_UPDATE_CURRENT);
am.cancel(pi);
mDatasource.deletePendingIntent(id);
Intent refresh = new Intent();
refresh.setClassName("com.somitsolutions.android.smsscheduler", "com.somitsolutions.android.smsscheduler.CancelAnAlarmActivity");
startActivity(refresh);
}
public void DeleteAnForOnceAlarmEntryFromDatabase(int id){
mDatasource.deletePendingIntent(id);
/*Intent refresh = new Intent();
refresh.setClassName("com.somitsolutions.android.smsscheduler", "com.somitsolutions.android.smsscheduler.CancelAnAlarmActivity");
startActivity(refresh);*/
}
}
I'm getting the same type of warning message in my other java codes.

Answer 1

You have declared mDetailsButton as a field variable but you commented all the parts that contain this variable. That's why you got a warning of unused variable.
