I don't think write once run everywhere applies to Android. Any native code has to be compiled and embedded into the apk, so you need to know at least which target architecture toolchains to install before you can start thinking about compiling it. Then we must consider any possible runtime differences between the various android distributions, "deprecated" API's at least. The only paths forward are to either accept google's full control over the various API's that it artificially imposes over it's linux base system, and may break app compatability, or use something more close to actual linux which claims to "never break userspace"
