这是我第一次使用 Android-Facebook SDK。我正在尝试发布位图，但我一直收到此消息:

Warning: Error: com.facebook.FacebookException: Failed to copy image.

我可以发布简单的链接，但不能发布带有照片的链接。

我应该如何解决这个问题？另外，我注意到的一件事是没有调用 StatusCallback.call()。

public abstract class FacebookReadyBaseActivity extends Activity {
    private static final String TAG = "FacebookReadyBaseActivity";

    private UiLifecycleHelper uiHelper;

    protected PendingAction pendingAction = PendingAction.NONE;
    private static final String PERMISSION = "publish_actions";
    protected boolean canPresentShareDialogWithPhotos;
    private boolean canPresentShareDialog;
    private GraphUser user;
    private GraphPlace place;
    private List<GraphUser> tags;
    protected Bitmap pendingBitmap;

    protected enum PendingAction {
        NONE, POST_PHOTO, POST_STATUS_UPDATE
    }

    private Session.StatusCallback callback = new Session.StatusCallback() {
        @Override
        public void call(Session session, SessionState state,
                Exception exception) {
            onSessionStateChange(session, state, exception);
        }
    };

    @Override
    protected void onCreate(Bundle savedInstanceState) {
        super.onCreate(savedInstanceState);

        uiHelper = new UiLifecycleHelper(this, callback);
        uiHelper.onCreate(savedInstanceState);

        canPresentShareDialog = FacebookDialog.canPresentShareDialog(this,
                FacebookDialog.ShareDialogFeature.SHARE_DIALOG);
        canPresentShareDialogWithPhotos = FacebookDialog.canPresentShareDialog(
                this, FacebookDialog.ShareDialogFeature.PHOTOS);
    }

    @Override
    protected void onActivityResult(int requestCode, int resultCode, Intent data) {
        super.onActivityResult(requestCode, resultCode, data);

        uiHelper.onActivityResult(requestCode, resultCode, data,
                new FacebookDialog.Callback() {
                    @Override
                    public void onError(FacebookDialog.PendingCall pendingCall,
                            Exception error, Bundle data) {
                        Log.e(TAG, String.format("Error: %s", error.toString()));
                    }

                    @Override
                    public void onComplete(
                            FacebookDialog.PendingCall pendingCall, Bundle data) {
                        Log.i(TAG, "Success!");
                    }
                });
    }

    @Override
    protected void onResume() {
        super.onResume();
        uiHelper.onResume();
    }

    @Override
    protected void onSaveInstanceState(Bundle outState) {
        super.onSaveInstanceState(outState);
        uiHelper.onSaveInstanceState(outState);
    }

    @Override
    public void onPause() {
        super.onPause();
        uiHelper.onPause();
    }

    @Override
    public void onDestroy() {
        super.onDestroy();
        uiHelper.onDestroy();
    }

    protected UiLifecycleHelper getFacebookUiHelper() {
        return uiHelper;
    }

    protected void performPublish(PendingAction action, boolean allowNoSession) {
        Session session = Session.getActiveSession();
        if (session != null) {
            pendingAction = action;
            if (hasPublishPermission()) {
                // We can do the action right away.
                handlePendingAction();
                return;
            } else if (session.isOpened()) {
                // We need to get new permissions, then complete the action when
                // we get called back.
                session.requestNewPublishPermissions(new Session.NewPermissionsRequest(
                        this, PERMISSION));
                return;

最佳答案

终于成功了!

在提供的 HelloFacebookSample 项目中，我在 list 中看到了这一点:

 <provider android:authorities="com.facebook.app.NativeAppCallContentProvider355198514515820"
                  android:name="com.facebook.NativeAppCallContentProvider"
                  android:exported="true"/>

我只是使用自己的 Facebook 应用程序 ID 更改了数字部分。不知道为什么我没有在文档中看到这一点。

编辑 后来发现:https://developers.facebook.com/docs/reference/android/current/class/NativeAppCallContentProvider/
