android - How to store sparsearray in bundle -

i have sparsearray<myobject> , want store in bundle in onsaveinstancestate method in activity , restore in oncreate. found putsparseparcelablearray method set sparsearray in bundle , did in onsaveinstancestate method:

bundle.putsparseparcelablearray("mysparsearray", mysparsearray);

but eclips shows error:

the method putsparseparcelablearray(string, sparsearray<? extends parcelable>) in type bundle not applicable arguments (string, sparsearray<myobject>)

and quick prepare casting argument mysparsarray sparsearray<? extends parcelable>, if , in oncreate method:

mysparsearray = (sparsearray<myobject>) savedinstancestate.getsparseparcelablearray("mysparsearray");

it gets error:

cannot cast sparsearray<parcelable> sparsearray<myobject>

if way wrong, solution set mysparsearray in bundle? help much appreciated.

your class should implement parcelable , should have static final fellow member variable called creator of type parcelable.creator<myobject>.
