没有废话直接上代码

var Intent = plus.android.importClass("android.content.Intent");  
var intent = new Intent(Intent.ACTION_MAIN);  
intent.addCategory(Intent.CATEGORY_LAUNCHER);  
var ComponentName = plus.android.importClass("android.content.ComponentName");  
var comp = new ComponentName("com.tencent.mm","com.tencent.mm.ui.LauncherUI");  
intent.setComponent(comp);  
//只想唤起微信就不要下面这句传参代码  
intent.putExtra("LauncherUI.From.Scaner.Shortcut", true);  
intent.setAction("android.intent.action.VIEW");  
var main = plus.android.runtimeMainActivity();  
main.startActivity(intent);  

用得上就点个赞,仅此而已
