Your code is pretty much boilerplate, I don't see anything wrong.
Perhaps the state you're getting in restore is not the state you saved?
Do you have views that are dynamically instantiated?
Are all views in the activity assigned unique id values?
Other than that, I'd try debugging with framework sources.

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];
}
};
}

The error happens while restoring view states (as already pointed out by
Zsolt), do you have any custom views in this activity? Do they have
methods to save / restore instance state?
It's hard to be more specific. Since it happens on your phone, you could
try debugging this into the framework sources.

Latest observation, if I am on activity A& then I kill app with app
killer application& after that I try to relaunch my app, generally
here above mentioned exception comes.

@Kostya, thanks for replying...I am not overriding
onSaveInstanceState()& onRestroreInstanceState() methods. So whatever
super ie Activity class has it is getting executed. Thats why I am
surprised that I am using Intent extras for my purpose and not
touching above 2 methods still its throwing exception in that method.
Any clue?

Thetypecodeis a prefix in the data stream that tells Parcelable the
typeof data that follows.
See Parcel.java, method readValue(), around lines 1700-1800.
All the codes are small numbers, between -1 and 24. Thecodein your
logcat is much larger.
This can be caused by data being read in a different order than it's
been written. For example:
parcel.writeInt(...)
parcel.writeString()
...
parcel.readString()
parcel.readInt()
It can also be caused by data corruption of some sort, for some reason.
You don't seem to be using parcel directly, but still, maybe this can
give you some more ideas.
There is a call to Activity.onRestoreInstanceState, so there is a
parcelable (bundle) involved here.

The stack trace you are showing doesn't seem to involve your intent
extras. It appears to be restoring the state of your screen when it's
crashing.

Hi,
I have one activity A with requires few values passed in intent. Those
values are oftypeboolean& int array. I am passing these these
values from activity B in intent as intent.putExtra(key1, boolean)&
intent.putExtra(key2, int[]). In activity A I am reading it as
Intent i = getIntent();
Bundle b = i.getExtras();
boolean flag = b.getBoolean(key1);
int[] array = b.getIntArray(key2);
It works perfect all the time but there is one case where it throws
exception
