Question

我有以下代码块将消息发送到我的设备，但消息未被发送...我不知道为什么......

以下是我构建GoogleApiClient的代码：

mClient = new GoogleApiClient.Builder(this)
            .addConnectionCallbacks(new ConnectionCallbacks() {
                @Override
                public void onConnected(Bundle bundle) {
                    Log.d("dirk", "Google API Client connected");
                    sendMessage();
                }

                @Override
                public void onConnectionSuspended(int cause) {
                    Log.d("dirk", "Google API Client disconnected, cause: " + cause);
                    mConnected = false;
                    mConnecting = false;
                    // TODO handle disconnect
                }
            })
            .addOnConnectionFailedListener(new OnConnectionFailedListener() {
                @Override
                public void onConnectionFailed(ConnectionResult result) {
                    Log.d("dirk", "Google API Client connection failed, reason: " + result);
                    mConnected = false;
                    mConnecting = false;
                    // TODO handle connection failure
                }
            })
            .addApi(Wearable.API)
            .build();

这是我从sendMessage方法调用的代码：

Wearable.MessageApi.sendMessage(getClient(), nodeId, PATH, null).setResultCallback(new ResultCallback<SendMessageResult>() {
        @Override
        public void onResult(SendMessageResult sendMessageResult) {
            if (!sendMessageResult.getStatus().isSuccess()) {
                Log.d("dirk", "message could not be sent: " + sendMessageResult.getStatus().toString());
                Log.d("dirk", "Client connected: " + getClient().isConnected());
                // TODO show communication error
            }
        }
    });

日志记录在这里：

Google API Client connected
message could not be sent: Status{statusCode=unknown status code: 4004, resolution=null}
Client connected: true

因此所有条件似乎都很好，但未知错误代码4004无法解决（至少到目前为止我没有发现任何错误）。任何人都知道这可能是什么原因？

我发现了一份支持我之前评论的文档。请查看WearableStatusCodes类 - 它包含WearableApi方法结果中使用的状态代码。 https://developer.android.com/reference/com/google/android/gms/wearable/WearableStatusCodes.html#INVALID_TARGET_NODE

因此，此错误不再是＆＃34;未知＆＃34; :) - 4004是INVALID_TARGET_NODE的代码。
请检查您在nodeId变量中传递的值。
