IWXAPI api = WXAPIFactory.createWXAPI(context, appId, false);
            WXLaunchMiniProgram.Req req = new WXLaunchMiniProgram.Req();
            req.userName = userId;
            if (TextUtils.isEmpty(path)) {
                req.path = “”;
            } else {
                req.path = path;
            }
            if (TextUtils.isEmpty(mini)) {
                req.miniprogramType = WXLaunchMiniProgram.Req.MINIPTOGRAM_TYPE_RELEASE;
            } else {
                req.miniprogramType = WXLaunchMiniProgram.Req.MINIPROGRAM_TYPE_PREVIEW;
            }
            api.sendReq(req);
            
            
微信版本7.0.6

appId: wx516f09ef989c1298
userId，req.userName: gh_b52e04a0100c   
path="";
mini="";
req.miniprogramType = WXLaunchMiniProgram.Req.MINIPTOGRAM_TYPE_RELEASE;

我也遇这个问题，但确认appid没用错， 应用签名，大小写都试过，帮我看原因

    public static final String TAG = MainActivity.class.getSimpleName();
 
    // APP_ID 替换为你的应用从官方网站申请到的合法appID
    private static final String APP_ID = "wx82d0****fe25eb40";
 
    // IWXAPI 是第三方app和微信通信的openApi接口
    private IWXAPI api;
 
    private BroadcastReceiver broadcastReceiver;
 
    private void regToWx() {
        // 通过WXAPIFactory工厂，获取IWXAPI的实例
        api = WXAPIFactory.createWXAPI(this, APP_ID, true);
 
        // 将应用的appId注册到微信
        api.registerApp(APP_ID);
 
        broadcastReceiver = new BroadcastReceiver() {
            [@Override](/user/Override)
            public void onReceive(Context context, Intent intent) {
 
                // 将该app注册到微信
                api.registerApp(APP_ID);
            }
        };
 
        //建议动态监听微信启动广播进行注册到微信
        registerReceiver(broadcastReceiver, new IntentFilter(ConstantsAPI.ACTION_REFRESH_WXAPP));
 
    }
 
    // 调启我的小程序
    private void goMiniProgram(){
        WXLaunchMiniProgram.Req req = new WXLaunchMiniProgram.Req();
        req.userName = "wxbd6534d10790****"; // 填小程序原始id
        req.path = "pages/index/index"; //拉起小程序页面的可带参路径，不填默认拉起小程序首页
        req.miniprogramType = WXLaunchMiniProgram.Req.MINIPTOGRAM_TYPE_RELEASE; //.MINIPTOGRAM_TYPE_RELEASE; // 可选打开 开发版，体验版和正式版
        api.sendReq(req);

你好，可以先对照文档排除一下问题：https://open.weixin.qq.com/cgi-bin/showdocument?action=dir_list&t=resource/res_list&verify=1&id=21526646437Y6nEC&token=&lang=zh_CN

我这边解决了 appid用错了

Android端应该用应用appid而不是小程序appid来WXAPIFactory.createWXAPI(context, appId, false); 

但是ios端只需要小程序原始id 这两个appid（应用appid和小程序appid）都不需要用到

但是什么错误提示都没有！！！就提示一个“跳转失败”！！！

这点设计的真的太次了！！！
