Android In-app billing : "RESULT_DEVELOPER_ERROR"

Question

I am unable to understand why i get a "RESULT_DEVELOPER_ERROR" in my implementation of "in-app billing".

What i've done :

• copy code from the sample application to my app
• android manifest contains the ""
• a test account declared in the Google Play console on a Xoom device under Android 4.0.4 with Google Play app version 3.5.19
• I am able tu use successfully the four reserved product ids : "android.test.purchased", "android.test.canceled", "android.test.refunded", "android.test.item_unavailable"
• declare my own product id
• my app is published on Google Play

The begining of exchanges with Google Play is :

• call "checkBillingSupported" from the service
• get a "onBillingSupported(true)" answer
• call "restoreTransactions" from the service
• get a "onRestoreTransactionsResponse" with "responseCode" equas to 5 (RESULT_DEVELOPER_ERROR)
• the UI says "This version of application is not configured for billing"

Then I am able to use the 4 reserved product id ?

Is there something i missed ?

The app needs to be signed with your production key and the one uploaded to Google Play should be the same version as the one you are testing with.
