How to Port OEM-Specific Apps to Other Devices
Most, if not all OEMs, like to bundle devices with their own iterations of certain apps, especially music players, gallery apps, and video players. Most of the time, they’re not that different from one another, despite how much each OEM makes them out to be. Despite this, many folks still have their favorites in regards to which app they like best. This may be because they’ve recently moved on to another OEM’s device, or simply because they like the look of it.
Unfortunately, because these apps are developed only for the OEM’s own devices, not everyone is able to download and use them. Sure, there are worthy alternatives in the Play store, but some people are looking for a specific experience that they normally couldn’t get with other devices. One way to overcome this issue is to port these apps over, and XDA Recognized Themer and Contributor Rizal Lovins has written a tutorial on how to do just that.
The tutorial lays down the process needed to port OEM-specific apps, such as Sony Xperia Walkman app, to other devices. It outlines the requirements, the APK decompiling process, and points out the various lines of code that need to be changed. Rizal Lovins warns that not all apps can be ported this way and that porting apps native to Jelly Bean and Ice Cream Sandwich to Gingerbread will be quite difficult.
So if your device doesn’t have a port of an app native to another device and you would like to give this a go, visit the original thread for more information.
