[Résolu] Gérer les changements de configuration sous Android

Bonjour
Voici le code qui permet de gérer les changements de configuration sous Android:
private LruCache<String, Bitmap> mMemoryCache;

@Override
protected void onCreate(Bundle savedInstanceState) {
...
RetainFragment retainFragment =
RetainFragment.findOrCreateRetainFragment(getFragmentManager());
mMemoryCache = retainFragment.mRetainedCache;
if (mMemoryCache == null) {
mMemoryCache = new LruCache<String, Bitmap>(cacheSize) {
... // Initialize cache here as usual
}
retainFragment.mRetainedCache = mMemoryCache;
}
...
}

class RetainFragment extends Fragment {
private static final String TAG = "RetainFragment";
public LruCache<String, Bitmap> mRetainedCache;

public RetainFragment() {}

public static RetainFragment findOrCreateRetainFragment(FragmentManager fm) {
RetainFragment fragment = (RetainFragment) fm.findFragmentByTag(TAG);
if (fragment == null) {
fragment = new RetainFragment();
fm.beginTransaction().add(fragment, TAG).commit();
}
return fragment;
}

@Override
public void onCreate(Bundle savedInstanceState) {
super.onCreate(savedInstanceState);
setRetainInstance(true);
}
}
