错误 - Facebook SDK 未在 Android 上初始化

Question

我按照 Facebook 快速入门指南将 facebook sdk 与 android 应用程序连接起来，以便使用图形 api。完成所有步骤并运行时，它显示无效的应用程序 ID。

2020-08-19 13:09:42.254 19754-19807/com.example.posttofb E/GraphResponse: {HttpStatus: 400, errorCode: 100, subErrorCode: 33, errorType: GraphMethodException, errorMessage: Unsupported get request. Object with ID '###########' does not exist, cannot be loaded due to missing permissions, or does not support this operation. 

这是清单：

    <application
        <meta-data android:name="com.facebook.sdk.ApplicationId" android:value="@string/facebook_app_id"/>
    </application>

将清单更改为android:resource="@string/facebook_app_id"，它现在要求使用FacebookSdk.sdkInitialize()，即使该方法已被弃用。

    The SDK has not been initialized, make sure to call FacebookSdk.sdkInitialize() first.

        at com.facebook.FacebookSdk.getApplicationContext(FacebookSdk.java:603)

发布图片的代码：

public void post() {
        try {
            GraphRequest request = GraphRequest.newPostRequest(
                    AccessToken.getCurrentAccessToken(),
                    "/{group-id}/feed",
                    new JSONObject("{\"message\":\"Posting from android studio.\"}"),
                    new GraphRequest.Callback() {
                        @Override
                        public void onCompleted(GraphResponse response) {
                            Log.v("MainActivity","error in message posting");
                        }
                    });
            request.executeAsync();

        }

您是否在 application.java 文件中添加了FacebookSdk.sdkInitialize()？
