Android InAppBilling getSkuDetails returns null

I've been working on IAB V3, and have been having trouble, when trying to get the sku details off the store. After cheking for result failure of the inventory query, I try to get the details with inv.getSkuDetails(MODULE).getPrice(); This always returns null, and when debugging I can see that the inventory object is empty.
However These requests always return null.
I am aware that google requires you to upload an apk to the alpha release channel (and release it) and have the InAppPurchase active (I also gave the store a few days to take over the changes). To test I used the same APK as uploaded to the alpha channel.
The IabHelper obviously managed to connect to the right app, as a test purchase was possible, and could be queried from the store.
Code:
`mHelper = new IabHelper(MainActivity.this, getString(getString(R.string.key1));
mHelper.startSetup(new IabHelper.OnIabSetupFinishedListener(){
#Override
public void onIabSetupFinished(IabResult result) {
if (!result.isSuccess()) {
Log.d(TAG, "Problem Setting up Billing" + result);
return;
}
IabHelper.QueryInventoryFinishedListener mQueryFinishedListener = new IabHelper.QueryInventoryFinishedListener() {
#Override
public void onQueryInventoryFinished(IabResult result, Inventory inv) {
if (result.isFailure()) {
Toast.makeText(getApplicationContext(), R.string.connectionFailed, Toast.LENGTH_SHORT).show();
Log.d(TAG, result.getMessage() + result.getResponse() + inv.toString());
return;
}
String modulePrice = inv.getSkuDetails(MODULE).getPrice();
String moduleTitle = inv.getSkuDetails(MODULE).getTitle();
String moduleDescription=inv.getSkuDetails(MODULE).getDescription();
}
}
ArrayList<String> skuList=new ArrayList<String>();
skuList.add(MODULE);
try {
mHelper.queryInventoryAsync(true, skuList, mQueryFinishedListener);
} catch (IabHelper.IabAsyncInProgressException e) {
e.printStackTrace();
}
}
});`
Ignore the wrong indentation and missing brackets, as i cut out some code.
I greatly appreciate any ideas as to what could be causing this problem.
Thanks

Error You Already Own This Item

I have a new android app in which I am adding in-app billing and I am tearing my hair out with frustration.
I have uploaded a signed APK and published to alpha. I created a set of in-app products and activated them all. I have created a new gmail account and defined them as a tester for the app on the app apk page.
I have factory reset my android phone and initialised it with the new gmail account. I have entered the /apps/testing link in to chrome and signed up as a tester. I then downloaded and installed my app. Inside my app I asked for the in app products that were available and was shown the set i created above. I selected one to buy and went through the following purchase process.
1. Screen shows product to be purchased and price and requests press continue which i do
2. Screen shows payment methods and I select redeem code
3. Screen shows redeem your code and I enter one of the promotion codes I set up in the developer console earlier (not mentioned above - sorry) and press redeem
4. Screen shows product again, this time with price crossed out and offers option to add item which I select (very strange being asked to add again buy hey ho)
5. Screen shows item added
6. After a fews seconds screen shows Error you already own this item.
How can this be, this user did not exist before ten minutes ago and has only used this app once as described above.
I have seen many questions in stack overflow and elsewhere similar to this and tried everything, clearing google play store cache, clearing google play store data etc. This sequence described above is my latest attempt with a completely clean user on a completely clean phone.
I could upload my app code used but that misses the point, which is how can this gmail account already own an item when this gmail account have never purchased anything before from anyone. Surely this is a bug.
All clues very welcome as to how to proceed. Code now added, note this is a hybrid android app, with the user purchase decisions code in javascript/html and the in app actions in the wrapper code below

String command = commandJSON.getString("method");

I have found that this error does not occur when using paypal (i.e. real money) to make the purchase, so I believe that this "Error you already own this item" message is in some way connected to using a promotion code for the test. And (so far) my paypal account has not been charged (as I am a resgistered tester for the app).

Android in App billing test purchase crashes Play store

I am currently developing an app with in App billing. all works fine. and I already published the app in Beta channel and tested it with test users with real items, and it works.
However while debugging, I am using the android.test.purchased item, my play store crashes when I press the buy button.
and I get the following error(s):

Purchase finished: IabResult: Null data in IAB result (response: -1002:Bad response received), purchase: null
Error purchasing: IabResult: Null data in IAB result (response: -1002:Bad response received)
sometimes the purchase continues after that, and other times, my app crashes.
I tested this on several devices (Nexus 7 with Android 6.0, Note 5 with Android 5.1.1, Galaxy S3 with Android 4.3, LG G3 with Android 4.4), all have the same behavior.
What makes me mad is that real in app items work flawlessly. which makes me think this means my code is fine. but having this happening with the test items, make me worried that it might be repeated with real items with real users when published.
I appreciate your assistance to let me know if I am doing something wrong leading to play store crashing, or this can happen?
please note that I am fairly new to Android development.
Thanks.

The problem was in Google Play v6.0.0, it is now fixed in v6.0.5 (confirmed both on a Samsung and a Nexus device).
If you didn't get the Google Play update automatically, you can download it manually from ApkMirror.com etc.

Google Play In-App Billing: Test purchase does not work + No product details available

I am trying to add Googles In-App Billing to my Android 4+ app. I have set up everything as described in "Preparing Your In-app Billing Application". Now I have uploaded the app to the Alpha testing channel in the Developer console.
Additionally I have set up a test account (described here) to be able purchase the items without triggering a real payment.
After installing the alpha version from the Play Store on my test device (using the test account of course) there a two problems:
No product information is fetched from the Play Store. Thus I cannot show any price information, etc.
When I start a purchase there is absolutly no hint, that this will be a free test purchase. Everything looks exactly like a real purchase.
This is the code I use:
String publicKey = MyApp.getPublicKey(); // de-code and get the public key
final IabHelper googlePlayHelper = new IabHelper(context, publicKey);
Log.d("TAG", "IabHelber Init");
googlePlayHelper.startSetup(new IabHelper.OnIabSetupFinishedListener() {
public void onIabSetupFinished(IabResult result) {
if (!result.isSuccess()) {
Log.d("TAG", "IabHelber Init - Non Success: " + result);
} else {
Log.d("TAG", "IabHelber Init - SUCCESS");
try {
googlePlayHelper.queryInventoryAsync(true, new IabHelper.QueryInventoryFinishedListener() {
public void onQueryInventoryFinished(IabResult result, Inventory inventory) {
if (result.isFailure()) {
Log.d("TAG", "query Inventory - Non Success: " + result);
} else {
Log.d("TAG", "query Inventory - SUCCESS");
if (inventory.hasDetails(2my.product.id")) {
Log.d("TAG", "NO DETAILS");
} else {
Log.d("TAG", "Has Details");
}
}
}
}
} catch (Exception e) {
Log.d("TAG", "EXCEPTION: " + e.getMessage());
}
}
}
});
The Log shows the following:
D/TAG (25995): IabHelber Init
D/TAG (25995): IabHelber Init - SUCCESS
D/TAG (25995): query Inventory - SUCCESS
D/TAG (25995): NO DETAILS
What could be the reason that now details are fetched?
The docs that that there should be an hint when performing a test purchase. Why am I runnig a "real" purchase instead?

I have not been able to find out why purchases by test users are not handled as test purchases. But the problem with the missing product details is solved:
I used the following call to query the inventory:
googlePlayHelper.queryInventoryAsync(true, new IabHelper.QueryInventoryFinishedListener() { ... });
This is totally valid code and the first parameters (true in this example) states, that the query should fetch the product details. But it seems, that this parameter does not have any effect until a further parameter is given: One has to explicitly specify the IDs of the product one would like to fetch:
List<String> productIDs = new ArrayList<String>();
productIDs.add(IAP_ID_1);
productIDs.add(IAP_ID_2);
productIDs.add(IAP_ID_3);
googlePlayHelper.queryInventoryAsync(true, productIDs, new IabHelper.QueryInventoryFinishedListener() { ... });

Android inventory.getSkuDetails() returning null

Hi i'm trying to add in app purchases to my app i have set up my in app purchases on the developer console which are set to active i have then queried them which yesterday was working perfectly i retrieved all the details but today its coming back as null. the only thing that has changed is that i had to uninstall the app and re-run it. I have checked my skus both in the app and on the developer console which match exactly when i run IabHelper start setup i get a result of ok. And then i call IabHelper.QueryInventoryFinishedListener and that results back as being ok but when i try access anything from the inventory it comes back as null. does anyone know why? or if i'm doing some wrong in my code?
in my on Create();
mHelper = new IabHelper(this, base64EncodedPublicKey);
mHelper.startSetup(new IabHelper.OnIabSetupFinishedListener() {
public void onIabSetupFinished(IabResult result) {
if (!result.isSuccess()) {
// Oh noes, there was a problem.
Log.v("Menu", "Problem setting up In-app Billing: " + result);
}
// Hooray, IAB is fully set up!
Log.v("Menu", "INAPP BILLING SETUP COMPLETE: " + result);
ArrayList<String> skuList = new ArrayList<String> ();
skuList.add("myapp.consumable.inapppurchase_id_1");
skuList.add("myapp.consumable.inapppurchase_id_2");
skuList.add("myapp.consumable.inapppurchase_id_3");
skuList.add("myapp.permanant.inapppurchase_id_6");
skuArray = new JSONArray(skuList);
mHelper.queryInventoryAsync(true, skuList, mQueryFinishedListener);
}
});
Then i heres my code for the QueryListener
IabHelper.QueryInventoryFinishedListener mQueryFinishedListener = new IabHelper.QueryInventoryFinishedListener() {
public void onQueryInventoryFinished(IabResult result, Inventory inventory)
{
if (result.isFailure()) {
Log.v("Menu", "RESULT FALIURE");
return;
}
Log.v("Menu", "this +" + skuArray);
Log.v("Menu", "Inventory +" + inventory);
for(int i = 0; i < skuArray.length(); i++){
try {
String SKU = skuArray.getString(i);
if(inventory.getSkuDetails(SKU) != null){
Log.v("Menu", "SKU = " + SKU);
Log.v("Menu", "SKU" + SKU + "= " + inventory.getSkuDetails(SKU));
updateProductData("price",inventory.getSkuDetails(SKU).getPrice(),i);
updateProductData("id",inventory.getSkuDetails(SKU).getSku(),i);
}else{
Log.v("Menu", "SKU RETURNED NULL" + SKU);
}
} catch (JSONException e) {
// TODO Auto-generated catch block
e.printStackTrace();
}
}
}
};

Ok i spoke to Google about this issue. And they say they have made changes which requires the apk to be published before adding in app purchases they recommend uploading the apk to alpha testing channel and published (not in draft mode).
Ill give it a try and feed back if it works

After I published my alpha apk to google play the billing started to work again.
