I'm trying to purchase test item-id "android.test.purchased", to check my billing integration. But got the following error:

com.android.vending.api.ApiException: Error from backend. 
Request=com.android.vending.model.GetImageRequest, Response=BAD_REQUEST

To avoid this error you need to upload your application to google market. But you don't need to publish it, just upload. https://market.android.com/publish/Home
