I am currently developing an application using application billing. everything is working fine. and I already published the application in the beta channel and tested it with test users with real elements, and it works.
However, during debugging, I use the android.test.purchased element, my game store crashes when I click the buy button.
and I get the following errors:
E/AndroidRuntime: FATAL EXCEPTION: main Process: com.android.vending, PID: 25463 java.lang.NullPointerException: Attempt to read from field 'com.google.android.finsky.protos.Acquisition$AutoDismissTemplate com.google.android.finsky.protos.Acquisition$PostAcquisitionPrompt.autoDismissTemplate' on a null object reference at com.google.android.finsky.billing.SuccessStep.getLayoutResId(SuccessStep.java:75) at com.google.android.finsky.billing.lightpurchase.PurchaseFragment.onStateChange(PurchaseFragment.java:31066) at com.google.android.finsky.fragments.SidecarFragment.notifyListener(SidecarFragment.java:255) at com.google.android.finsky.fragments.SidecarFragment.setState(SidecarFragment.java:250) at com.google.android.finsky.billing.lightpurchase.CheckoutPurchaseSidecar.confirmAuthChoiceSelected(CheckoutPurchaseSidecar.java:631) at com.google.android.finsky.billing.lightpurchase.PurchaseFragment.onStateChange(PurchaseFragment.java:32156) at com.google.android.finsky.fragments.SidecarFragment.notifyListener(SidecarFragment.java:255) at com.google.android.finsky.fragments.SidecarFragment.setState(SidecarFragment.java:250) at com.google.android.finsky.billing.lightpurchase.CheckoutPurchaseSidecar.access$1900$2f730cd3(CheckoutPurchaseSidecar.java:72) at com.google.android.finsky.billing.lightpurchase.CheckoutPurchaseSidecar$1.run(CheckoutPurchaseSidecar.java:1009) at android.os.Handler.handleCallback(Handler.java:739) at android.os.Handler.dispatchMessage(Handler.java:95) at android.os.Looper.loop(Looper.java:148) at android.app.ActivityThread.main(ActivityThread.java:5417) at java.lang.reflect.Method.invoke(Native Method) at com.android.internal.os.ZygoteInit$MethodAndArgsCaller.run(ZygoteInit.java:726) at com.android.internal.os.ZygoteInit.main(ZygoteInit.java:616) 11-23 02:22:43.202 590-739/? W/ActivityManager: Force finishing activity com.android.vending/com.google.android.finsky.billing.lightpurchase.IabV3Activity 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 in other cases my application crashes.
I tested this on multiple 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 drives me crazy is that the real things in the application work flawlessly. which makes me think it means my code is ok. but if this happens with test items, make me worry that this could be repeated with real items with real users when posting.
I appreciate your help to let me know if I am doing something wrong, which leads to a malfunction in the store, or can it happen?
note that I'm pretty new to Android development.
Thanks.
Here is my billing code in the app:
///... part of onCreate: mHelper = new IabHelper(this, base64EncodedPublicKey); mHelper.startSetup(new IabHelper.OnIabSetupFinishedListener() { public void onIabSetupFinished(IabResult result) { if (!result.isSuccess()) { Log.d(TAG, "In-app Billing setup failed: " + result); } else { // Hooray, IAB is fully set up. Now, let get an inventory of // stuff we own. Log.d(TAG, "Setup successful. Querying inventory."); mHelper.queryInventoryAsync(mGotInventoryListener); } } });
/////////////////
public void startPurchase(String ITEM_SKU) { // Start the purchase process here String purchaseToken = "inapp:" + getPackageName() + ":"+ ITEM_SKU; Log.d(TAG, "Purchase started for : " + ITEM_SKU); mHelper.launchPurchaseFlow(this, ITEM_SKU, 10002, mPurchaseFinishedListener, purchaseToken); } // Callback for when a purchase is finished IabHelper.OnIabPurchaseFinishedListener mPurchaseFinishedListener = new IabHelper.OnIabPurchaseFinishedListener() { public void onIabPurchaseFinished(IabResult result, Purchase purchase) { Log.d(TAG, "Purchase finished: " + result + ", purchase: " + purchase); if (result.isFailure()) { Log.d(TAG,"Error purchasing: " + result); if (result.getResponse()==7){ if(myInventory.hasPurchase(ITEM_SKU)) { Log.d(TAG,"Ooops, Item already purchased, consume it"); mHelper.consumeAsync(myInventory.getPurchase(ITEM_SKU),mConsumeFinishedListener2); } } return; } Log.d(TAG, "Purchase successful."); if (purchase.getSku().equals(ITEM_SKU)) { mHelper.consumeAsync(purchase, mConsumeFinishedListener); } } }; IabHelper.QueryInventoryFinishedListener mGotInventoryListener = new IabHelper.QueryInventoryFinishedListener() { public void onQueryInventoryFinished(IabResult result, Inventory inventory) { Log.d(TAG, "Query inventory finished."); if (result.isFailure()) { Log.d(TAG,"Failed to query inventory: " + result); return; } Log.d(TAG, "Query inventory was successful."); myInventory = inventory; //Process inventory } }; IabHelper.OnConsumeFinishedListener mConsumeFinishedListener = new IabHelper.OnConsumeFinishedListener() { public void onConsumeFinished(Purchase purchase, IabResult result) { if (result.isSuccess()) { Log.d(TAG,"consume successful for " + purchase.getSku() + " & " + result.getMessage()); updateCoinsAndScore(coinsToAdd, 0); Toast.makeText(getApplication(), "تم إضافة عدد " + coinsToAdd + " عملات إلى رصيدك", Toast.LENGTH_LONG).show(); //reset values coinsToAdd=0; ITEM_SKU=""; } else { Log.d(TAG, "Consume failed " + result.getMessage()); } } }; IabHelper.OnConsumeFinishedListener mConsumeFinishedListener2 = new IabHelper.OnConsumeFinishedListener() { public void onConsumeFinished(Purchase purchase, IabResult result) { if (result.isSuccess()) { Log.d(TAG,"consumed, starting purchase again"); Log.d(TAG,"consume successful for " + purchase.getSku() + " & " + result.getMessage()); startPurchase(ITEM_SKU); } else { Log.d(TAG,"Consume failed " + result.getMessage()); } } };
