Conversion of apk files to java file format

It looks like the only feasible apk to java conversion would be done with Xenotix APK Decompiler or similar tools, which are used to convert  Google Android application packages (.apk) to Java files. Unfortunately, this appears to work only for very basic Android apps and might not work for more complex apps at all, or with issues and errors.
