yes I am using one custom ViewGroup & I am handling saveInstanceState
& restoreInstanceState in it.(I just forgot to think about this custom
view). So yup I understand the probability is the exception comes
here. I checked my code, it has only 1 state variable to store. So no
miss-order handling is there. When I write to parcel its size is 660 &
when read it size is 1013. here is the code snippet
protected Parcelable onSaveInstanceState() {
final SavedState state = new
SavedState(super.onSaveInstanceState());
state.currentState = this.currentState;
return state;
}
/**
* Restore the previous saved current screen
*/
@Override
protected void onRestoreInstanceState(Parcelable state) {
SavedState savedState = (SavedState) state;
super.onRestoreInstanceState(savedState.getSuperState());
if (savedState.currentScreen != -1) {
currentState = savedState.currentState;
}
}
// ========================= INNER CLASSES
==============================
public interface onViewChangedEvent {
void onViewChange(int currentViewIndex);
}
/**
* A SavedState which save and load the current screen
*/
public static class SavedState extends BaseSavedState {
int currentState = -1;
/**
* Internal constructor
*
* @param superState
*/
SavedState(Parcelable superState) {
super(superState);
}
/**
* Private constructor
*
* @param in
*/
private SavedState(Parcel in) {
super(in);
Log.d("------------", "parcelsize() in "+in.dataSize());
currentState = in.readInt();
}
/**
* Save the current screen
*/
@Override
public void writeToParcel(Parcel out, int flags) {
super.writeToParcel(out, flags);
out.writeInt(currentState);
Log.d("------------", "parcelsize() out
"+out.dataSize());
}
/**
* Return a Parcelable creator
*/
public static final Parcelable.Creator<SavedState> CREATOR = new
Parcelable.Creator<SavedState>() {
public SavedState createFromParcel(Parcel in) {
return new SavedState(in);
}
public SavedState[] newArray(int size) {
return new SavedState[size];
}
};
}
