Service sharedpreferences updating value in activity

My service class can edit and store new value of sharedpreferences

so i want to retrieve it in another activity, its working fine.

Now what i would like to do, once service altered sharedpreferences, i want the sharedprefrences value to be updated in activity.

I used timer but it returns nullpointerexception. Any idea why?

Use an OnPreferenceChangeListener to monitor changes to your SharedPreference.

Not sure how a timer would help you in the scenario you've described. You may want to look into other options, such as:

  • Using a BroadcastReceiver
  • Binding the service to the activity & using the AIDL to define handlers.
