http://stackoverflow.com – Is the Google Wallet on Android phones mandatory for e.g. movie, songs or game levels purchases in a similar way the Apple’s In-App-Purchase is on iOS? According to the information here “Developers offering additional content, goods, or services for an application downloaded from Android Market must offer an authorized Payment Processor as the payment option“. Our understanding is that if user has installed an application, which plays movies and users pay per single movie view application needs using the Google Wallet otherwise it can be removed from Google Play. Is that correct? S (HowTos)
