loader - Android: LoaderCallbacks.OnLoadFinished called twice

Question

I noticed strange situation using Android Loaders and Fragments. When I invoke LoaderManager.initLoader() after orientation change onLoadFinished is not called (although documentation suggests I should be prepared for this) but it is called twice after this. Here is link to post in google groups which describe the same situation https://groups.google.com/forum/?fromgroups#!topic/android-developers/aA2vHYxSskU . I wrote sample application in which I only init simple Loader in Fragment.onActivityCreated() to check if this happens and it does. Anyone noticed this?

Answer 1

You can put the initLoader() method inside your Fragment's onResume() callback; then the Loader's onLoadFinished() will not be called twice anymore.

    @Override
public void onResume()
{
    super.onResume();
    getLoaderManager().initLoader(0, null, this);
}
