autojs hot update dex example

Before switching to dex, go to the js obfuscation website and rename all the variables and method names in js.

Transfer the obfuscated js to dex, which is more secure..

"ui";

var DexName = "aaa.dex";
var DexVersionName = "DexVersion.js";
//本地文件
var LocalDirPath = "/sdcard/xxx辅助/";
var LocalDexPath = LocalDirPath + DexName;
var LocalVersionFilePath = LocalDirPath + DexVersionName;

//网络文件
var RemoteHost = "http://自己的地址/";
var RemoteDexFilePath = RemoteHost + DexName;
var RemoteVersionFilePath = RemoteHost + DexVersionName;
