android-service

There's a REST service that I use to populate info in my database, that is later used by my app. I've read several threads on the matter, and now have to decide how I want the sync between the REST service and my DB to work. Think of an app that gets info from google finance APIs about stocks and stores it in a DB, displays the information when the app is launched, and sends notifications when specific events happen in the stock price.

For studying the Android service, I wrote a test program that have three button "bind service", "unbind service" and "send echo" on the screen.

Try again. mGoogleApiClient.connect(); } } else { // Show dialog using GooglePlayServicesUtil.getErrorDialog() mResolvingError = true;
