Thanks Romain,
Did not work... still the exception...
It occurs on a View with an ID set to 'container'.
And i went into my View hierarchy to check. All looks fine.:
There is only one view with the id set to 'container'.
Every other view in the hierarchy has a unique name or no id at all.
And still i get the exception after my process is killed, restarted
and my view is about to be restored....
Doing super.onRestoreInstanceState(BaseSavedState.EMPTY_STATE); gets
rid of that exception.
Here's my code-snippet.
@Override
protected void onRestoreInstanceState(Parcelable parcelable) {
if (parcelable instanceof ViewBundle) {
final ViewBundle viewBundle = (ViewBundle)parcelable;
mSaveState = viewBundle.getBundle();
// Note that mRestoredBitmapOffFullSizedImage can be null!
// It won't be null on a configuration change, but it may be
// after this view's process/activity is restarted.
mRestoredBitmapOffFullSizedImage =
(Bitmap)viewBundle.getTransient
("bitmapholder");
super.onRestoreInstanceState(viewBundle.getSuperState());
}
else {
// TODO
// This exception can be thrown when:
// Do edit image (Effects)
// Open Dialer app, make sure process
smugdroid.process.pictures
is killed.
// Then return to SnapFX -->
// java.lang.IllegalArgumentException: Wrong state class --
expecting View Sate.
// Fixed it by always using BaseSavedState.EMPTY_STATE instead
of
'parcelable'....
super.onRestoreInstanceState(parcelable); // <-- Exception
happens
here when using 'parcelable'.
}
}
