Hello, I'm facing this problem : I'm using Compatibility package to use fragment in android application (min SDK 2.1). An random exception occurs on fragment sometimes and I can't figure out why. This is the stack trace I receive: java.lang.IllegalStateException: Fragment FeedListFragment{438a54e8} not attached to Activity at android.support.v4.app.Fragment.getLoaderManager(Fragment.java:715) at com.myappli.ui.FeedListFragment.refreshUpdateDate(FeedListFragment.java:283) at com.myappli.ui.phone.FeedListActivity.onReceiveResult(FeedListActivity.java:277) at com.myappli.data.rssplayer.service.KTDetachableResultReceiver.onReceiveResult(KTDetachableResultReceiver.java:55) at android.os.ResultReceiver$MyRunnable.run(ResultReceiver.java:43) at android.os.Handler.handleCallback(Handler.java:587) at android.os.Handler.dispatchMessage(Handler.java:92) at android.os.Looper.loop(Looper.java:136) at android.app.ActivityThread.main(ActivityThread.java:4425) at java.lang.reflect.Method.invokeNative(Native Method) at java.lang.reflect.Method.invoke(Method.java:521) at com.android.internal.os.ZygoteInit$MethodAndArgsCaller.run(ZygoteInit.java:860) at com.android.internal.os.ZygoteInit.main(ZygoteInit.java:618) at dalvik.system.NativeStart.main(Native Method) Here is the corresponding code I'm calling in the Fragment class: public class FeedListFragment extends ListFragment implements LoaderManager.LoaderCallbacks<Cursor>, FeedListCursorAdapterListener { ... public void refreshUpdateDate() { getLoaderManager().restartLoader(LAST_UPDATE_CURSOR_ID, null, this); } ... } Here is the code of the activity that calls the fragment: private FeedListFragment mCursorLoaderListFg; if (!isFinishing()) { mCursorLoaderListFg.refreshUpdateDate(); mCursorLoaderListFg.refreshDisplay(); mCursorLoaderListFg.hideLoadi
