Game developer tip 5: Using proper versioning

If you haven’t put much thought into how you assign the application versioning for your game, it is definitely an important detail you should keep in mind. Correct versioning makes it easier for you to maintain the development of your game, and makes it easier for users to keep track of what version they are running. This is the fifth in a series of tips that supplement the XperiaTM game developer recommendations. This tip expands on Packaging recommendations – PK6 in the list of game developer recommendations: For the final version of a game, the version value should be “1.0.0” or higher and the current APK version should be higher than for any of the game’s previous releases.

Sony Ericsson supports independent developers

In developer forums worldwide, there is a huge activity and engagement in the open Android™ ecosystem. And we also know there are a lot of independent developers out there who are creating their own custom ROMs or modifying the kernel. The Sony Ericsson Developer program is following this community with great interest, and even though Sony Ericsson is not supporting all the activities by independent developers, we recognize that custom ROMs are a part of the Android ecosystem.

We therefore decided to assist a group of developers called “FreeXperia”. The overall open developer community is important to Sony Ericsson, and we hope to learn from it, and share knowledge ourselves. The FreeXperia group was supported with devices and technical know-how, and they are now in the process of creating custom ROMs based on the CyanogenMod for several of our latest Xperia™ phones, including Xperia™ PLAY and Xperia™ arc.

Karl-Johan Dahlström, Head of Developer Relations, explains more after the jump.

Important note: By unlocking your phone and running a custom ROM you may void the warranty. See your phone’s warranty statement for details.
