1.某些APP安装在模拟器时提示“ this probably means that the app contains ARM native code and your Genymotion device cannot run ARM instructions. You should either build your native code to x86 or install an ARM tanslation tool in your device.” 解决方案:1.下载并安装Genymot
Your script code is compiled into DLLs (assemblies) by the editor. When you build for iOS, these assemblies are converted into Arm machine code. This process is called AOT (ahead-of-time) compilation. Well, in fact, the Mono tools are spitting out Ar
