mService.consumePurchase(3, packageName, purchaseT

问题:

I'm always getting "RESULT_DEVELOPER_ERROR = 5 - invalid arguments provided to the API", when trying to consume a purchase with

String purchaseToken = "inapp:" + getPackageName() + ":" + productId;
int response = 0;
try {
    response = mService.consumePurchase(3, getPackageName(), purchaseToken);
} catch (RemoteException e) {
    // TODO Auto-generated catch block
    e.printStackTrace();
}

For that reason, I can always only make a purchase once. However, I need to be able to make the purchase much more often. I've been trying to fix this problem for 2 days now, no success. :/

Making and consuming purchases with SKU "android.test.purchased" works completely fine, however as soon as I export the .apk with the production key and add a live SKU, the purchase only shows up once and then never again.

Here some more details

1. The version code of the .apk in the play store and the exported .apk I'm using on my phone are the same and were signed with the same keystore
2. I've tried it for both managed and unmanaged products, however that shouldn't matter, because according to the latest in-app billing documentation, managed and unmanaged are treated as managed products and both have to be consumed
3. I only have 5 SKU items, so it doesn't hit the limit of 20, which was the problem here

The purchase token is different from the SKU itself, instead, you should retrieve the purchaseToken via code such as:

// Note the null is the continueToken you may not get all of the purchased items
// in one call - check ownedItems.getString("INAPP_CONTINUATION_TOKEN") for 
// the next continueToken and re-call with that until you don't get a token
Bundle ownedItems = service.getPurchases(3, getPackageName(), "inapp", null);
// Check response
int responseCode = ownedItems.getInt("RESPONSE_CODE");
if (responseCode != 0) {
   throw new Exception("Error");
}
// Get the list of purchased items
ArrayList<String> purchaseDataList = 
    ownedItems.getStringArrayList("INAPP_PURCHASE_DATA_LIST");
for (String purchaseData : purchaseDataList) {
    JSONObject o = new JSONObject(purchaseData);
    String purchaseToken = o.optString("token", o.optString("purchaseToken"));
    // Consume purchaseToken, handling any errors
    mService.consumePurchase(3, getPackageName(), purchaseToken);
}

I just found that if you add more than 20 items to ITEM_ID_LIST for getSkuDetails then it will return RESULT_DEVELOPER_ERROR too.
