example运行起来后报错，我把代码集成到项目以后，setAlias同样报错

一样的 大佬 你解决了么？

修改result运行在主线程，自定义MainThreadResult类实现MethodChannel.Result接口

class MainThreadResult implements MethodChannel.Result {
    private MethodChannel.Result result;
    private Handler handler;

    MainThreadResult(MethodChannel.Result result) {
        this.result = result;
        handler = new Handler(Looper.getMainLooper());
    }

    @Override
    public void success(final Object o) {
        handler.post(
                new Runnable() {
                    @Override
                    public void run() {
                        result.success(o);
                    }
                });
    }

    @Override
    public void error(
            final String errorCode, final String errorMessage, final Object errorDetails) {
        handler.post(
                new Runnable() {
                    @Override
                    public void run() {
                        result.error(errorCode, errorMessage, errorDetails);
                    }
                });
    }

    @Override
    public void notImplemented() {
        handler.post(
                new Runnable() {
                    @Override
                    public void run() {
                        result.notImplemented();
                    }
                });
    }
}

在JPushEventReceiver.java的onAliasOperatorResult中

 @Override
    public void onAliasOperatorResult(Context context, JPushMessage jPushMessage) {
        super.onAliasOperatorResult(context, jPushMessage);

        int sequence = jPushMessage.getSequence();

        Result callback = JPushPlugin.instance.callbackMap.get(sequence);
        if (callback == null) {
            Log.i("JPushPlugin", "Unexpected error, callback is null!");
            return;
        }
++   callback = new MainThreadResult(callback);
        if (jPushMessage.getErrorCode() == 0) { // success
            Map<String, Object> res = new HashMap<>();
            res.put("alias", (jPushMessage.getAlias() == null) ? "" : jPushMessage.getAlias());
            callback.success(res);

        } else {
            callback.error(Integer.toString(jPushMessage.getErrorCode()), "", "");
        }

        JPushPlugin.instance.callbackMap.remove(sequence);
    }

能把这问题rp吗
