我正在尝试 dataitem APi，这是我的代码

mGoogleApiClient = new GoogleApiClient.Builder(this)
            .addConnectionCallbacks(new GoogleApiClient.ConnectionCallbacks() {
                @Override
                public void onConnected(Bundle connectionHint) {
                    Log.d("Inside", "onConnected: " + connectionHint);
                    Toast.makeText(getApplicationContext(),"Inside On connected",Toast.LENGTH_SHORT).show();
                    // Now you can use the Data Layer API
                    //Creating Dataitem
                    PutDataMapRequest dataMapRequest = PutDataMapRequest.create("/count");
                    dataMapRequest.setUrgent();
                    DataMap datamap=dataMapRequest.getDataMap();
                    PutDataRequest putDataRequest=dataMapRequest.asPutDataRequest();
                    datamap.putString("key", "Value");
                    PendingResult<DataApi.DataItemResult> pendingResult =
                            Wearable.DataApi.putDataItem(mGoogleApiClient, putDataRequest);
                }
                @Override
                public void onConnectionSuspended(int cause) {
                    Log.d("Inside", "onConnectionSuspended: " + cause);
                }
            })
            .addOnConnectionFailedListener(new GoogleApiClient.OnConnectionFailedListener() {
                @Override
                public void onConnectionFailed(ConnectionResult result) {
                    Log.d("Inside", "onConnectionFailed: " + result);
                } …
