title: Shared preferences between two processes of the same application
body: <p>I'm writing an Android app that contains both UI and separate processes running.
  I want to share simple information between the main process and a service defined in my application that is executed in a different process.
  I find to messy to use AIDL for inter-process communication for this purpose.</p>
  
  <p>The question is: Is it safe to use Shared Preferences of the application for communicating between this two processes? This is: both read and write the same shared preferences.</p>
  
  <p>I'm wondering if it actually works. In android developers reference about shared preferences (http://developer.android.com/reference/android/content/SharedPreferences.html) they state: <em>Note: currently this class does not support use across multiple processes. This will be added later.</em> but I don't know exactly what does this mean.</p>
  
  <p>Thanks for your help</p>
