title: In App billing not working after update - Google Store
body: <p>I have implemented In-App billing in my app - and very recently google has updated it,previously i was testing the in-app billing with <code>"android.test.purchased"</code> and it was working fine (Buy full Version and Restore full version).</p>
  
  <p>Now i took the changed classes from here 
  <a href="https://code.google.com/p/marketbilling/source/detail?r=7bc191a004483a1034b758e1df0bda062088d840">https://code.google.com/p/marketbilling/source/detail?r=7bc191a004483a1034b758e1df0bda062088d840</a></p>
  
  <p>After that i am not able to test the app it gives the following error in the Logcat <code>"IabHelper: In-app billing error: Purchase signature verification FAILED for sku android.test.purchased
  ".</code></p>
  
  <p>I have checked with my key, package name and also app version all is proper, has any one faced this issue?</p>
  
  <p>Please help me with this.</p>
