How to store sparsearray in bundle

I have a `SparseArray<myObject>` and want to store it in bundle in `onSaveInstanceState` method in my activity and restore it in `oncreate`. I found `putSparseParcelableArray` method for put SparseArray in bundle and did this in `onSaveInstanceState` method: ``` bundle.putSparseParcelableArray("mySparseArray", mySparseArray); ``` But eclips shows this error: ``` The method putSparseParcelableArray(String, SparseArray<? extends Parcelable>) in the type Bundle is not applicable for the arguments (String, SparseArray<myObject>) ``` And the quick fix is casting argument `mySparsArray` to `SparseArray<? extends Parcelable>`, but if I do so and get it in onCreate method: ``` mySparseArray = (SparseArray<myObject>) savedInstanceState.getSparseParcelableArray("mySparseArray"); ``` It gets this error: ``` Cannot cast from SparseArray<Parcelable> to SparseArray<myObject> ``` If this way is wrong, what is the solution for put mySparseArray in bundle? Any help would be much appreciated.
