Running a task every few hours

Question

I have a method that I need to run every few hours even if the user didn't reopen the app. What is the best way to go? Should I use the Timer class or Alarm manager? Thanks!

Answer 1

Step 1: Define 'Service' class to define logic to be executed

Ste 2: Define BroadcastReceiver and add in manifest xml. This is responsible for calling 'Service' class to do the task.

May be you need add intent action <action android:name="android.intent.action.BOOT_COMPLETED"/> under in manifest xml

Step 3: Use 'AlarmManager' to schedule to repeat
