In app purchase android: signature verification error

Use below tips to resolve it:

If you have used the android.test.purchased then one way to get rid of the error is to do the following:-

1. Edit Security.java and change the "return false" line in the verifyPurchase to "return true" - this is temporary, we'll be putting it back in a minute.
2. In your QueryInventoryFinishedListener, after the "if (result.isFailure()) {...}" lines add the following to consume and get rid of your never ending android.test.purchased item:-
   if (inventory.hasPurchase(SKU_ANDROID_TEST_PURCHASE_GOOD)) {
   mHelper.consumeAsync(inventory.getPurchase(SKU_ANDROID_TEST_PURCHASE_GOOD),null); }
3. Run your app so the consunmeAsync happens, this gets rid of the "android.test.purchased" item on the server.
4. Remove the consumeAsync code (or comment it out).
5. Back in the Security.java, change the "return true" back to "return false".
