    StartActivity();

this code do so strange thing it return when go to this line intent.putExtra("sparsearray",sa); so if a toast under it toast never appear so strange really

Answer 1

Just wrap your SparseArray in a Bundle and it should work.

Intent intent = new Intent(context, Activity.class);
Bundle bundle = new Bundle();
bundle.putSparseParcelableArray("SPARSE_ARRAY_KEY",sparseArray);
intent.putExtra("BUNDLE_KEY", bundle);

to get the SparseArray back you will need to unwrap the Bundle again. Hope this helps.
