我正在尝试在我的 Facebook android 游戏应用程序中实现发送数据并接受该数据。为此，我正在关注https://developers.facebook.com/docs/android/send-requests/#notifications教程。我可以发送请求，但是我无法在接收方接受数据。

我intentUri每次都返回null，所以我无法获取requestIds。

我在接收方获取数据的代码：

intentUri = MainActivity.this.getIntent().getData();
if (intentUri != null) {
    String requestIdParam = intentUri.getQueryParameter("request_ids");
    if (requestIdParam != null) {
        String array[] = requestIdParam.split(",");
        requestId = array[0];
        Log.i("Request id: ", "Request id: " + requestId);

    }else{
        Log.i("Request id: ", "null" );

    }
} else {
    Log.i("intentUri", "null");     //**Always printing this part**
}

onSessionStateChange() 方法用于调用 requestData 方法

private void onSessionStateChange(Session session, SessionState state,Exception exception) {
    if (state.isOpened() && requestId != null) {
        getRequestData(requestId);
        requestId = null;
    }
}

我正在使用以下方法发送请求：

private void sendRequestDialog() {
    Bundle params = new Bundle();
    params.putString("message",
            "Learn how to make your Android apps social");
    params.putString("data", "{\"badge_of_awesomeness\":\"1\","
            + "\"social_karma\":\"5\"}");
    WebDialog requestsDialog = (new WebDialog.RequestsDialogBuilder(
            MainActivity.this, Session.getActiveSession(), params))
            .setOnCompleteListener(new OnCompleteListener() {
                @Override
                public void onComplete(Bundle values,
                        FacebookException error) {
                    if (error != null) {
                        if (error instanceof FacebookOperationCanceledException) {
                            Toast.makeText(MainActivity.this,
                                    "Request cancelled", Toast.LENGTH_SHORT)
                                    .show();
                        } else {
                            Toast.makeText(MainActivity.this,
                                    "Network Error", Toast.LENGTH_SHORT)
                                    .show();
                        }
                    } else {
                        final String requestId = values
                                .getString("request");
                        if (requestId != null) {
                            Toast.makeText(MainActivity.this,
                                    "Request sent", Toast.LENGTH_SHORT)
                                    .show();
                        } else {
                            Toast.makeText(MainActivity.this,
                                "Request cancelled", Toast.LENGTH_SHORT)
                                .show();
                        }
                    }
                }
            }).build();
    requestsDialog.show();
}

接受请求的代码如下：

private void getRequestData(final String inRequestId) {
    // Create a new request for an HTTP GET with the
    // request ID as the Graph path.
    Request request = new Request(Session.getActiveSession(), inRequestId,
            null, HttpMethod.GET, new Request.Callback() {
                @Override
                public void onCompleted(Response response) {
                    // Process the returned response
                    GraphObject graphObject = response.getGraphObject();
                    FacebookRequestError error = response.getError();
                    // Default message
                    String message = "Incoming request";
                    if (graphObject != null) {
                        // Check if there is extra data
                        if (graphObject.getProperty("data") != null) {
                            try {
                                // Get the data, parse info to get the
                                // key/value info
                                JSONObject dataObject = new JSONObject(
                                        (String) graphObject
                                                .getProperty("data"));
                                // Get the value for the key -
                                // badge_of_awesomeness
                                String badge = dataObject
                                        .getString("badge_of_awesomeness");
                                // Get the value for the key - social_karma
                                String karma = dataObject
                                        .getString("social_karma");
                                // Get the sender's name
                                JSONObject fromObject = (JSONObject) graphObject
                                        .getProperty("from");
                                String sender = fromObject
                                        .getString("name");
                                String title = sender + " sent you a gift";
                                // Create the text for the alert based on
                                // the sender
                                // and the data
                                message = title + "\n\n" + "Badge: "
                                        + badge + " Karma: " + karma;
                            } catch (JSONException e) {
                                message = "Error getting request info";
                            }
                        } else if (error != null) {
                            message = "Error getting request info";
                        }
                    }
                    Toast.makeText(MainActivity.this, message,
                            Toast.LENGTH_LONG).show();
                    deleteRequest(inRequestId);
                }
            });
    // Execute the request asynchronously.
    Request.executeBatchAsync(request);
}

注意：我只是使用简单的活动，我没有使用片段

该方法getIntent()返回启动活动的意图。您可以尝试覆盖 Activity 方法

protected void onNewIntent(Intent intent)

并打电话

setIntent(Intent intent)

从那里。

您也可以尝试使用以下方式请求您的数据：

Intent intent = MainActivity.this.getIntent();
Bundle bundle = intent.getExtras();
intentUri = (Uri)bundle.get(Intent.EXTRA_TEXT);

除此之外，您在哪里以及如何打电话intent.putExtra("request_ids", data)？

不知道我是否完全理解你的问题，

无论如何，我祝你好运。

编辑：

您可能希望使用 Intent.EXTRA_STREAM 而不是 Intent.EXTRA_TEXT，具体取决于您存储数据的方式
