[android-developers] Re: Avoid restarting http request on orientation change

Depending on your specific needs, a service might make sense, but for simple cases, it's not strictly necessary. You can instead use Activity.onRetainNonConfigurationInstance(), which allows you to pass live Java objects to the new Activity instance - i.e., for example an AsyncTask object. Just mak

[android-developers] To save resources, should services use the android:process attribute?

I have a service that runs continuously. I opted to run the service in a separate process, communicating through IPC with the client activities, thinking this will help conserve memory. If the user is done interacting, Android could shut down the entire client side process. However, the protocol b

I had trouble with this too. The solution is to use support-screens to enable anyDensity=true. Simply setting "targetSdkVersion" to something >= 4 also works, since this makes anyDensity=true the default. I would have assumed that the SDK that you build against automatically is considered the targ
