Hi, 

We have a user that cannot complete a purchase. Whenever the code reaches the line:

store.purchase(productId)

the app crashes with the following exception:

java.lang.NullPointerException: Attempt to invoke virtual method 'java.lang.Object android.os.Bundle.get(java.lang.String)' on a null object reference Java Stack Trace: plugin.google.iap.v3.util.IabHelper.getResponseCodeFromBundle(IabHelper.java:809) plugin.google.iap.v3.util.IabHelper.launchPurchaseFlow(IabHelper.java:413) plugin.google.iap.v3.util.IabHelper.launchPurchaseFlow(IabHelper.java:359) plugin.google.iap.v3.util.IabHelper.launchPurchaseFlow(IabHelper.java:354) plugin.google.iap.v3.LuaLoader.purchase(LuaLoader.java:358) plugin.google.iap.v3.LuaLoader.access$1400(LuaLoader.java:37) plugin.google.iap.v3.LuaLoader$PurchaseWrapper.invoke(LuaLoader.java:469) com.ansca.corona.JavaToNativeShim.nativeTouchEvent(Native Method) com.ansca.corona.JavaToNativeShim.touchEvent(JavaToNativeShim.java:416) com.ansca.corona.input.RaiseTouchEventTask.executeUsing(RaiseTouchEventTask.java:39) com.ansca.corona.CoronaRuntimeTaskDispatcher$TaskEvent.Send(CoronaRuntimeTaskDispatcher.java:170) com.ansca.corona.events.EventManager.sendEvents(EventManager.java:91) com.ansca.corona.Controller.updateRuntimeState(Controller.java:305) com.ansca.corona.graphics.opengl.CoronaGLSurfaceView$CoronaRenderer.onDrawFrame(CoronaGLSurfaceView.java:421) com.ansca.corona.graphics.opengl.GLSurfaceView$GLThread.guardedRun(GLSurfaceView.java:1623) com.ansca.corona.graphics.opengl.GLSurfaceView$GLThread.run(GLSurfaceView.java:1378)

The user is using a Cubot Note S with the Android OS version 5.1.

The app was compiled with the simulator version 2016.2907. 

Any help will be greatly appreciated.

Thanks!

What is the value of productId?

#3

Since the platform is Android, the value of productId is a string representing the produce id in the Google Play store (it works for other Android users)

Sorry, I should have been more clear. I was hoping you would drop a print statement in and verify the value of productId when you get the crash. I was curious what the exact value was at the time of the crash.

I don’t understand why the actual product id’s we’re using are relevant for the crash…

It’s not a specific product that caused it, but all the products the user tries to purchase.

Our product id’s are all in the form of com.host.lower.caps.unique.name

I suspect the problem is related to the user’s Android OS, since a Bundle object is expected to be initialized and it’s null.
