片段未在Android 4.4.4中显示

Question

I tried with support Fragment as well as normal Fragment but nothing is displayed on the screen when I call launchAwesomeFragment() in (Nexus7 4.4.4). But in other phones the Fragment launches perfectly.

There was no errors or anything in logcat but sometimes the following log appers when I call launchAwesomeFragment() . What might be the problem here?

Could not find method android.support.v4.app.Fragment.performSaveInstanceState, referenced from method .AwesomeFragment

Here's my code of launchAwesomeFragment

private void launchAwesomeFragment() {
    FragmentTransaction transaction = getFragmentManager().beginTransaction();
    transaction.replace(R.id.container, AwesomeFragment.newInstance());
    transaction.addToBackStack(null);
    transaction.commit();
}

If you're using Eclipse, then you need to check if you've added the support library properly.

Project > Android Tools > Add support Library

Now clean and rebuild the application and then uninstall and reinstall to try again.

If you're using Android Studio, then you might try clean and build. But in Android Studio, this is not an usual case. Anyway, you might take a look at this answer here.

Generally these type of error log indicates the method is not found as the library is not referenced properly.

Hope that helps!
