android - Can I get data from shared preferences inside a service?

Question

I'm developing an android application. I'm using android 2.2

In my application I am capturing GPS data and sending it to service with the 1 hour time interval. If user exits from application it's also working (it is required).

I'm using 2 services (User defined), one for capturing GPS data and other for sending to the server.

Here my doubt

• In service, can we use shared preferences.

• If we store any data in shared preferences in any activity of the application, will we be able to use that data in service with the help of shared preferences?

Answer 1

You can access the default shared preferences instance, which is shared across all your Activity and Service classes, by calling PreferenceManager.getDefaultSharedPreferences(Context context):

SharedPreferences preferences = PreferenceManager.getDefaultSharedPreferences(this);

This is great for storing simple primitives (like booleans) or serializable objects. However, if you're capturing a lot of location data, you might consider using a SQLite database instead.
