Facebook分享对话框未显示-Android Facebook API

Question

On clicking the facebook share button the share dialog comes and immediately disappears. In the shareDialog.registerCallback it goes to onError method. Don't understand why is it happening.

CallbackManager callbackManager;
    ShareDialog shareDialog;

 @Override
    protected void onCreate(Bundle savedInstanceState) {
        super.onCreate(savedInstanceState);
        setContentView(R.layout.activity_main);
FacebookSdk.setApplicationId(String.valueOf(R.string.facebook_app_id));
        FacebookSdk.sdkInitialize(getApplicationContext());
        callbackManager = CallbackManager.Factory.create();
        shareDialog = new ShareDialog(this);

shareDialog.registerCallback(callbackManager, new FacebookCallback<Sharer.Result>() {
            @Override
            public void onSuccess(Sharer.Result result) {
                Toast.makeText(MainActivity.this, "onSuccess", Toast.LENGTH_SHORT).show();
            }

            @Override
            public void onCancel() {
                Toast.makeText(MainActivity.this, "onCancel", Toast.LENGTH_SHORT).show();
            }

            @Override
            public void onError(FacebookException error) {
                Toast.makeText(MainActivity.this, "Opps! Some error occurred. Please try again", Toast.LENGTH_SHORT).show();
            }
        });

bFbShare.setOnClickListener(new View.OnClickListener() {
            @Override
            public void onClick(View view) {
                if (ShareDialog.canShow(ShareLinkContent.class)) {
                    ShareLinkContent linkContent = new ShareLinkContent.Builder()
                      .setQuote("Hi ABCE")                     .setContentUrl(Uri.parse("https://play.google.com/store/apps/details?id=" + getApplicationContext().getPackageName()))
                            .build();
                    shareDialog.show(MainActivity.this, linkContent);
                }
            }
        });

In the Logcat i get this

GraphResponse: {HttpStatus: 404, errorCode: 803, subErrorCode: -1, errorType: OAuthException, errorMessage: (#803) Some of the aliases you requested do not exist: 2131492917}

Answer 1

从onClick删除if (ShareDialog.canShow(ShareLinkContent.class))是否对我if (ShareDialog.canShow(ShareLinkContent.class)) 。
