Sony is no longer mucking around with Android devices. The company announced today that it will no longer support releasing games on Android devices through its PlayStation Mobile initiative. Instead the company will put its focus back on PS Vita and its micro-console, the PS Vita TV.
The company launched PlayStation Mobile in 2012, allowing developers to publish games on the Vita without having to jump through the hoops of certification on that platform. It also allowed for publishing games to PlayStation-certified Android devices.
Sony Japan is encouraging developers who made games that way to focus on Vita game development. Given that Sony is doing a better job of supporting indie developers on all its platforms, this probably is the best advice it can give at this point...
