I have an existing application in the Android store where I would like to integrate the InApp purchase function. I read the api and implemented this feature and downloaded the new signed APK in beta mode. Then I tried to create products in applications in the InApp product section. But I do not see any option there. Please refer to the image below.
I found the answer to my question. Actually, I mistakenly added com.android.BILLING instead of com.android.vending.BILLING in the manifest file.
thank
