Amazon In App Purchase in Live App testing is not working - in-app-purchase

Question

I am facing some issues in Amazon In App Purchase in Live App Testing. I am stuck at this since last 4-5 days, tried a lots of solutions but not able to move further. I am using Amazon in app purchase SDK. I have taken sample project that comes with Amazon SDK. I have changed my SKU in it, For local testing i am usign App Tester and app is working fine. Now I have uploaded app on Live App testing and created IAP item on Amazon account then App on Live app testing stop working.
Activity onResume code is below-
#Override
protected void onResume() {
super.onResume();
sampleIapManager.activate();
Log.d(TAG, "onResume: call getUserData");
PurchasingService.getUserData();
Log.d(TAG, "onResume: getPurchaseUpdates");
PurchasingService.getPurchaseUpdates(false);
System.out.println(TAG + " onResume: call getProductData for skus: " + MySku.values());
final Set<String> productSkus = new HashSet<String>();
for (final MySku mySku : MySku.values()) {
System.out.println("TAG , SKU information = "+mySku.getSku());
productSkus.add(mySku.getSku());
}
PurchasingService.getProductData(productSkus);
}

Proguard file -
-dontwarn com.amazon.**
-keep class com.amazon.** {*;}
-keepattributes *Annotation*
-optimizations !code/allocation/variable
If proguard file does not contain -optimizations !code/allocation/variable
then when i click on purchase button then it shows me an error dialog.
and if i am putting the line -optimizations !code/allocation/variable then i am not getting onPurchase event. Please help me in it. i am stuck since last 5 days in it. Thanks in advance

Answer 1

Did you submit the IAP items on Amazon developer console? Their status should be "LIVE", otherwise your app cannot retrieve them at runtime. I suspect that's what caused the error message.
If that's not the problem, checking logcat should help identify the root cause.
