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

How can I implement restore purchase in android

Thanks for visiting my page.
Few days ago, I've developed simple android game with in app-billing.
Now I am going to implement restore purchase function but I don't know how can I dot it.
I've made few days of googling and found many links to help it but they didn't work me now.
Please let me know how to do it programmatically.
Where can i find sample of restore purchase ?
I've implemented in app purchase already but not restore purchase.
I used Android Studio 1.5.1.
I've refered http://www.techotopia.com/index.php/An_Android_Studio_Google_Play_In-app_Billing_Tutorial to implement in app purchase.
Please help me :(
Thanks in advance.

If you are implemented the InApp Purchase using v3 you need not worry about the restore Purchase implementation. You can query the inventory and catch the existing Purchase information. Please check the implementation.
What I did here is I have already a purchase module. While I complete the purchase, I will send the information to our server. After relog in or come back to the application, the server will send the current user purchase info whether he is Purchased or not. if the server gives a negative result, I will check the query inventory that is there any existing purchase over there. For that, I am using the following code in the MainActivity onCreate().
mHelper = new IabHelper(this, base64EncodedPublicKey);
mHelper.enableDebugLogging(true);
Log.d(TAG, "Starting setup.");
mHelper.startSetup(new IabHelper.OnIabSetupFinishedListener() {
public void onIabSetupFinished(IabResult result) {
Log.d(TAG, "Setup finished.");
if (!result.isSuccess()) {
Log.e(TAG, "In App Set UP error:: Please check gmail account settings/ Credit Card Info etc");
return;
}
if (mHelper == null) return;
mBroadcastReceiver = new IabBroadcastReceiver(MainActivity.this);
IntentFilter broadcastFilter = new IntentFilter(IabBroadcastReceiver.ACTION);
registerReceiver(mBroadcastReceiver, broadcastFilter);
Log.d(TAG, "Setup successful. Querying inventory.");
if (mSupplier.getmSubscriptionStatus() == 0) { // This is the Status given from Local Server 0- UnScubscribed User, 1- Subscribed User
mHelper.queryInventoryAsync(mGotInventoryListenerForPurchase);
}
}
});
In the Result, You can Identify the existing purchase information.
IabHelper.QueryInventoryFinishedListener mGotInventoryListenerForPurchase = new IabHelper.QueryInventoryFinishedListener() {
public void onQueryInventoryFinished(IabResult result, Inventory inventory) {
try {
Log.d(TAG, "Query inventory For Purchase finished.");
String payload = // Your developer payload
if (mHelper == null) return;
if (result.isFailure()) {
Log.v(TAG, "PURCHSE RESULT ERROR- NO PURCHASE AVAILABLE");
return;
}
Log.v(TAG, "Query inventory For Purchase was successful.");
if (mSkuDetailList == null || mSkuDetailList.isEmpty()) {
Log.v(TAG, "SKU INFO FROM LOCAL SERVER- UNABLE TO PURCHASE");
return;
}
Purchase premiumPurchase = null;
for (IabSkuDetailModel data : mSkuDetailList) {
// Filter the purchase info using SKU:::
premiumPurchase = inventory.getPurchase(data.getmPackageName());
if (premiumPurchase != null) {
break;
}
}
if (premiumPurchase == null) {
Log.v(TAG, "NO Available Purchase for this user");
return;
}
if (verifyDeveloperPayload(premiumPurchase)) {
Log.v(TAG, "Purchase is there already ::: developer payload is Matching:: This need to update Local Server: No need to purchase agian");
if (premiumPurchase.getSku().equalsIgnoreCase(mSelectedSku)) {
IabPurchaseUpdateReq request = new IabPurchaseUpdateReq();
request.setmPurchaseToken(premiumPurchase.getToken());
request.setmUserId("" + mSupplier.getmUserId());
request.setmPublicKey(IabConstants.IAB_RSA_PUBLIC_KEY);
request.setmSignature(premiumPurchase.getSignature());
request.setmSubscriptionId(premiumPurchase.getSku());
request.setmPurchaseObj(premiumPurchase.getOriginalJson());
//Update "result to local Server"
} else {
Log.v(TAG, "SKU mismatch ::: ");
}
} else {
Log.v(TAG, "Developer payload error:: Wrong Purchase");
}
} catch (Exception e) {
e.printStackTrace();
}
}
};

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):

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.

My products are Managed products in developer account In-app Products
EDIT:
When I use android.test.purchased as a SKU then it works fine and as I change my sku with my product_id then it giving me Error Authentication is required. You need to sign into your Google Account.

Please make sure your product id on playstore for in app purchase which is "test_product" you should use the same sku in your code. And if you change the sku from your application, then all that possible sku names must exists on PlayStore as in-app Products. I once run into this problem and the reason was my SKU item was not exists on Google Playstore in-app products i just add it on Playstore and it was resolved.

Android IAB Error - Authentication required
It seems that you need to publish the APK. I stuck with this problem too.

It is a bit of a longshot, but your "Google Play store" app could be malfunctioning.
I have a report from a customer that he cannot make an In-App purchase and he is getting this same error. I also know that we are still getting purchases. So I don't think you necessarily configured anything wrong. IAB v3 could simply be malfunctioning with your "Google Play Store" app.
Try going to Settings open the Application manager and choose the "Google Play store" application in the list, and click on "Uninstall updates" button which appears there. Next try to do the purchase again. If your old Google Play application supports In-App billing v3 it will work. If it doesn't, try to update the "Google Play store" app again, perhaps you will get a newer/different version of the store app and you will be able to make the purchase.
As an alternative you can try and configure a second test device with a different Google account... or ask a friend to join a beta test group and make a test purchase.
I am not really happy with IAB v3. It feels a little clunky. V2 had fewer features but felt solid.

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() {

if (!result.isSuccess()) {
Log.d("TAG", "IabHelber Init - Non Success: " + result);
} else {

try {
googlePlayHelper.queryInventoryAsync(true, new IabHelper.QueryInventoryFinishedListener() {

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() { ... });
