微信多开软件系统源码，应用层多开的核心实现，Android系统多账户原理。

      微信多开有多种实现方式，一种是apk反编译修改微信包名的方式，不过这种方式会改变微信的东西，微信对这些在严格封杀。一种是利用Android的多账户原理，让微信工作在不同的用户下，就可以实现多个微信同时运行的效果。另外一种是系统层的多开，这个大家有空可以去研究下。这里我们重点介绍Android多账户，应用层多开的实现。

           话不多说，直接上代码：

 InstalledAppInfo installInfo = VirtualCore.get().getInstalledAppInfo(this.appInfo.packageName, 0);
// InstalledAppInfo installInfo = VirtualCore.get().getInstalledAppInfo(this.appInfo.packageName, 1);
 if (installInfo != null) {
     if (this.appInfo.versionCode < getPackageInfo(this.mContext, this.appInfo.packageName).versionCode) {
         Log.i("mylog", "need update!");
         isUpdate = true;
     } else {
         Log.i("mylog", "just launch !");
         showInstallAnim(false, "");
         new Thread(new Runnable() {
             public void run() {
                 Log.i("mylog", "startActivity");
                // final Intent intent = VirtualCore.get().getLaunchIntent(BaseMainActivity.this.appInfo.packageName, 0);
                 final Intent intent = VirtualCore.get().getLaunchIntent(BaseMainActivity.this.appInfo.packageName, userid);
                 try {
                     VirtualCore.get().preOpt(BaseMainActivity.this.appInfo.packageName);
                 } catch (Exception e) {
