In app billing on Android shows error : 1003 : Purchase signature verification failed

I am trying to verify whether product is purchased or not from store.
For that I have used the below code :
mHelper.queryInventoryAsync(mGotInventoryListener);
And call back is as mentioned below :
IabHelper.QueryInventoryFinishedListener mGotInventoryListener = new IabHelper.QueryInventoryFinishedListener() {
public void onQueryInventoryFinished(IabResult result, Inventory inventory) {
Log.d(TAG, "Query inventory finished.");
// Have we been disposed of in the meantime? If so, quit.
if (mHelper == null) return;
// Is it a failure?
**if (result.isFailure()) { // This fails in our case**
complain("Failed to query inventory: " + result);
return;
}
}
};
But every time I am getting same error as shown in below attached screen.
I have tried with below mentioned steps but failed to get success.
"base64EncodedPublicKey" verified from our google play account where app is launched in alpha testing mode
Application is signed with release keystore
"base64EncodedPublicKey" - copied to notepad first and then copy to java file (read somewhere in blogs for this solution) , but that has not work for me.
Can anybody suggest for the same. Please let me know if I need to add something in order to solve this issue?

Are you trying to purchase android.test.purchased or another item? If you are using android.test.purchased, check this answer, it should answer your question: Android in app purchase: Signature verification failed

Found the solution :)
There was an issue with registering a broadcast receiver.
Plese find below code of startSetup method which is registering broadcast receiver that was missing from the following snippet.
mHelper.startSetup(new IabHelper.OnIabSetupFinishedListener() { public void onIabSetupFinished(IabResult result) {
if (!result.isSuccess()) {
// Oh noes, there was a problem.
Log.d(TAG, "Problem setting up In-app Billing: " + result);
} mBroadcastReceiver = new IabBroadcastReceiver(MainActivity.this);
IntentFilter broadcastFilter = new IntentFilter(IabBroadcastReceiver.ACTION);
registerReceiver(mBroadcastReceiver, broadcastFilter);
// Hooray, IAB is fully set up! }});

In-app billing v3 test purchase not working across devices

I have setup three Managed items in my developer account for in-app purchases, and my app is currently in the Beta channel on the Play Store.
I want to test the in-app purchase across two devices that use the same Google account -- but am finding that only the device that makes the purchase is correctly finding the purchase. The second device, using the same Google account, does not find the purchase.
Should test account billing work across any device that uses the same Google account?
I'm using the Billing helper libraries and here's my code at start-up to check for purchases:
ActivityStartUp.java
#Override
public void onIabSetupFinished(IabResult result)
{
if (!result.isSuccess())
{
LOGD(TAG, "In-app Billing setup failed: " + result);
startApplication();
}
else
{
LOGD(TAG, "In-app Billing is set up OK");
// Query In-App billing for purchases
mHelper.queryInventoryAsync(new QueryInventoryFinishedListener()
{
#Override
public void onQueryInventoryFinished(IabResult result, Inventory inv)
{
if (inv.hasPurchase(Globals.ITEM1_SKU) ||
inv.hasPurchase(Globals.ITEM2_SKU) ||
inv.hasPurchase(Globals.ITEM3_SKU))
{
// Store PRO purchase state
AccountUtils.setProVersion(ActivityStartUp.this, true);
LOGD(TAG, "Ad-free. User has purchased the Upgrade :)");
}
else
{
// Store PRO purchase state
AccountUtils.setProVersion(ActivityStartUp.this, false);
LOGD(TAG, "Using the free version, with Ads");
}
// Start the application
startApplication();
}
});
}
}

Implementing In-app Billing

I am currently working on in app purchase in my application, when it launches I have always the error code -1003 querying owned items response signature verification failed when I arrive in IabHelper.QueryInventoryFinishedListener method.
I currently uses the example version of Google "Trivial Drive", I guess my signature is correct because I get to buy much when I use android.app.purchassed ...
The key seems correct to me because when I click like to buy a product that tells me that the publisher can not buy the product which is normal in itself (If I put anything I have another error saying the product does not exist). For cons, I have the same error when I put the test product "android.test.purchasse" then I should be able to test with it.
I made a purchase with android.test.purchasse there and I can not reset if you have already succeeded I'm interested.

Have you ever been concerned? I see no way out for this bug help from you will be appreciated.
thank you

You need to create a test account, and put it in the playstore admin page.

In-app-purchase just won't work

I am currently trying to configure my app for in app purchase, but it just won't work. Every time I try to start the purchase flow it says "This version of the applications is not configured for billing through Google Play". I am quite sure that I walked through al necessary steps to make it work. I also tested SKU-Id "android.test.purchased", which works fine.
base64EncodedPublicKey is def. correct and exactly teh same like the code from the developer console
I did not forget <uses-permission android:name="com.android.vending.BILLING" /> in my manifest
I have applied the google account that I am using on my testing device as a tester account in the developer console
I am using the exactly same APK on my device an in the developer console. I installed it on my device via adb -d install
So any ideas what I could have done wrong?
This is my code:
(onCreate)
base64EncodedPublicKey
iabHelper = new IabHelper(this, base64EncodedPublicKey);
iabHelper.startSetup(new IabHelper.OnIabSetupFinishedListener() {
#Override
public void onIabSetupFinished(IabResult result) {
if (!result.isSuccess()) {
// Oh noes, there was a problem.
Log.d(PURCHASE_TAG, "Problem setting up In-app Billing: " + result);
} else if (result.isSuccess()){
// Hooray, IAB is fully set up!
Log.d(PURCHASE_TAG, "Setup completed: " + result);
iabHelper.queryInventoryAsync(true, null, queryFinishedListener);
}
}
});
(onActivityResult)
if (iabHelper.handleActivityResult(requestCode, resultCode, data)) {
Log.d("TAG", "onActivityResult handled by IABUtil.");
return;
}
(Button click for starting burchase flow)
if(isPremium){
saveImageToGallery(imageState.image);
} else if (iabHelper != null) {
iabHelper.flagEndAsync();
purchaseItem(SKU_TEST);
(purchaseItem())
private void purchaseItem(String sku) {
iabHelper.launchPurchaseFlow(this, sku, 10001,
purchaseFinishedListener);
}
(listeners)
IabHelper.QueryInventoryFinishedListener
queryFinishedListener = new IabHelper.QueryInventoryFinishedListener() {
public void onQueryInventoryFinished(IabResult result, Inventory inventory)
{
if (result.isFailure()) {
// handle error
return;
} else if (result.isSuccess()){
Log.d("$$$$$$$$$$$$$$$", "" + result);
}
}
};
IabHelper.OnIabPurchaseFinishedListener purchaseFinishedListener
= new IabHelper.OnIabPurchaseFinishedListener() {
public void onIabPurchaseFinished(IabResult result, Purchase purchase)
{
if (result.isFailure()) {
Log.d("ERROR_TAG", "Error purchasing: " + result);
return;
}
else if (purchase.getSku().equals(SKU_TEST)) {
// give user access to premium content and update the UI
isPremium = purchase.getSku().equals(SKU_TEST);
}
}
};

I think you should check the key store you signed your apk. You must use same key store for apk that has uploaded to Google Play and test.

I hade the same problem, I fixed it by:
Go to play store developer console
Settings > Manage Testers, then add your another test email, not the one you use in publishing apps.
Again under Developer Console, Account Details (scroll down) > License Testing and add the emails of your users who will test your
app.
On your device, login in play store with one of the test emails 3 you allowed.
Launch you app and make in app purchase. There should be fixed.

Summary:

Android: InAppBilling

I am working on an app which has IAB, and that when the purchase is finished through the OnConsumeFinishedListener, it will save through SharePreference that the user has paid for the additional function (the function wont be depleted).
Users are able to buy again for the same product.
Code:
// Called when consumption is complete
IabHelper.OnConsumeFinishedListener mConsumeFinishedListener = new IabHelper.OnConsumeFinishedListener()
{
public void onConsumeFinished(Purchase purchase, IabResult result)
{
Log.d(TAG, "Consumption finished. Purchase: " + purchase + ", result: " + result);
if (mHelper == null) return;
if (result.isSuccess())
{
Toast.makeText(InAppBillingActivity.this, "Thank you!!", Toast.LENGTH_SHORT).show();
if ((purchase.getSku().equals(ITEM_SKU10))) {countQ(10);}
buy10Button.setEnabled(true);
}
else
{
// handle error
}
Log.d(TAG, "End consumption flow.");
}
};
public void countQ(int Q)
{
SharedPreferences settings = this.getSharedPreferences("MyApp",0);
if (Q==10)
{
SharedPreferences settings1 = this.getSharedPreferences("MyApp",0);
SharedPreferences.Editor e1 = settings1.edit();
e1.putBoolean("userpaid", true);
e1.commit();
}
Question:
I see that users are able to cancel their purchase. In that way, saving through Sharepreference that the user has paid for additional functions will have loophole? The user can first purchase to make the sharepreference to become true and then cancel the purchase order?
In that way, how can be the process be improved? Checking the inventory seem not possible as the additional function is consumed in the IAB process.

It seems a little odd that you have a non-consumable item that can be purchased multiple times. The idea is generally that an item that can be purchased multiple times is consumable.
To answer your question IAB purchases cannot be cancelled like an app purchase can, the 15 minute refund window is removed and the purchase is non-refundable unless they contact you and you decide to issue a refund manually.
