We detected that your app(s) listed at the end of this email are invoking the in-app billing service without setting a target package for the intent. This can enable a malicious package to bypass the Play store billing system and access items that have not been purchased.
Next Steps
If you are using IabHelper, please start using the latest SDK.
If you are manually invoking the in-app billing service, make sure you are calling Intent.setPackage(“com.android.vending”) on any intents to "com.android.vending.billing.InAppBillingService.BIND".
Sign in to your Developer Console and submit the updated version of your app.
Check back after five hours - we’ll show a warning message if the app hasn’t been updated correctly.
