1.Integrate the BlockStore API to your test app.
2.Use the test app to invoke the BlockStore API to store your data.
3.Uninstall your test app and then reinstall your app on the same device.
4.Use the test app to invoke the BlockStore API to retrieve your data.
5.Verify that the bytes retrieved are the same as what were stored before uninstallation.
