我已经设置了简单的Facebook登录.对于 Android 2.3.6,所有功能都应该如此,用户获得提示登录对话框,输入数据和应用程序继续.我以为这是android版本的错误,但是当手机上安装了Facebook应用程序时,会发现登录不起作用！

测试了：
galaxy Ace 2.3.6
HTC Desire 4.1.2
银河笔记4.1.2
Android模拟器4.1.2

即使Facebook的样品也不工作！

每次应用执行时 – else {
Log.d(“SESSION NOT OPENED”,“SESSION NOT OPENED”);
}

似乎会话没有打开,但为什么呢？按照本指南 – https://developers.facebook.com/docs/getting-started/facebook-sdk-for-android/3.0/

码：

Session.openActiveSession(this,true,new Session.StatusCallback() {

        @Override
        public void call(final Session session,SessionState state,Exception exception) {

            if (session.isOpened()) {

                Request.executeMeRequestAsync(session,new Request.GraphUserCallback() {

                    @Override
                    public void onCompleted(GraphUser user,Response response) {
                        if (user != null) {
                            Log.d("Access_token",session.getAccesstoken());
                        }
                    }
                });
            } else {
                Log.d("SESSION NOT OPENED","SESSION NOT OPENED");
            }
        }
    });

查看步骤4： https://developers.facebook.com/docs/getting-started/facebook-sdk-for-android/3.0/的底部

如果您没有正确输入应用程序密钥哈希,Facebook通过WebView弹出窗口登录(如果该应用未安装)仍然可以正常工作,但是通过本机的Facebook应用程序登录将不会.

您应该在LogCat中看到这个异常：

com.facebook.http.protocol.ApiException: remote_app_id does not match stored id

Facebook SDK打印其例外,如果还有其他问题,请检查.

我想从我的 Android应用程序打开一个Facebook链接.
URL看起来像 http://www.facebbok.com/abcxyz.它应该在Facebook应用程序中打开’abcxyz’页面,但它总是在浏览器中打开.

码：

try 
{
    Intent browserIntent = new Intent(Intent.ACTION_VIEW,Uri.parse(url));
    activityContext.startActivity(browserIntent);
} 
catch (ActivityNotFoundException ex) 
{
     ex.printstacktrace();
}

我的Android操作系统版本是6.0.1.

我和Instagram,http://www.instagram.com/abcxyz有同样的问题,而Youtube等其他应用程序也有问题.

您应该使用Facebook的自定义网址方案强制应用打开您的页面,如下所示：

public Intent getFacebookIntent(String url) {

  PackageManager pm = context.getPackageManager();
  Uri uri = Uri.parse(url);

  try {
    ApplicationInfo applicationInfo = pm.getApplicationInfo("com.facebook.katana",0);
    if (applicationInfo.enabled) {
      uri = Uri.parse("fb://facewebmodal/f?href=" + url);
    }
  }  

  catch (PackageManager.NameNotFoundException ignored) {
  }

  return new Intent(Intent.ACTION_VIEW,uri);
}

我已经构建了一个使用 this实现的活动(请参阅接受的答案),在用户的Facebook墙上发布状态更新.

如果模拟器/手机没有安装Facebook应用程序,它没有问题.

如果模拟器/手机安装了Facebook应用程序,Facebook应用程序加载登录屏幕,但在尝试登录后,Facebook应用程序刚刚消失,将我带回我的应用程序.

安装Facebook应用程序时有没有人有这种体验？

我的代码：

public class AchievementActivity extends Activity implements DialogListener,OnClickListener{


private Facebook facebook;
Button facebookPostButton;
String defaultFacebookPost;

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

    requestwindowFeature(Window.FEATURE_CUSTOM_TITLE);
    setContentView(R.layout.achievements);
    getwindow().setFeatureInt(Window.FEATURE_CUSTOM_TITLE,R.layout.custom_title_layout);

    View achievementDivider = (View)findViewById(R.id.achievementDivider);
    int[] colors = {0,0xff00ffff,0};
    achievementDivider.setBackgroundDrawable(new GradientDrawable(Orientation.RIGHT_LEFT,colors));

    //get the title of the achievement from the intent that started this activity from the activity StatisticsActivity
    String achievementTitleString = getIntent().getStringExtra("title");

    String achievementTextTodisplay = getAchievementTextTodisplay(achievementTitleString);

    defaultFacebookPost = getDefaultPost(achievementTitleString);

    //ImageView achievementActivityAchievementBadgeImageView = (ImageView)findViewById(R.id.achievementActivityAchievementBadgeImageView);
    TextView achievementActivityBadgeTitleTextView = (TextView)findViewById(R.id.achievementActivityBadgeTitleTextView);
        achievementActivityBadgeTitleTextView.setText(achievementTitleString);

    TextView achievementActivityAchievementText = (TextView)findViewById(R.id.achievementActivityAchievementText);
        achievementActivityAchievementText.setText(achievementTextTodisplay);

    facebookPostButton = (Button)findViewById(R.id.facebookPostButton);
    facebookPostButton.setonClickListener(this);


}

@Override
public void onComplete(Bundle values) {

    if (values.isEmpty())
    {
        Toast.makeText(getApplicationContext(),"Empty",Toast.LENGTH_SHORT);

        return;
    }

    if (!values.containsKey("post_id"))
    {
        try
        {
            Bundle parameters = new Bundle();
            parameters.putString("message",defaultFacebookPost);// the message to post to the wall
            facebook.dialog(AchievementActivity.this,"stream.publish",parameters,this);// "stream.publish" is an API call
        }
        catch (Exception e)
        {
            // Todo: handle exception
                System.out.println(e.getMessage());
        }
    }

    try 
    {
        facebook.logout(getApplicationContext());
    } 
    catch (MalformedURLException e) 
    {
        // Todo Auto-generated catch block
        e.printstacktrace();
    } 
    catch (IOException e) 
    {
        // Todo Auto-generated catch block
        e.printstacktrace();
    }
}

@Override
public void onFacebookError(FacebookError error) 
{
    Toast.makeText(AchievementActivity.this,"onFacebookError",Toast.LENGTH_LONG); 
}

@Override
public void onError(DialogError e) 
{
    Toast.makeText(AchievementActivity.this,"onError",Toast.LENGTH_LONG); 
}

@Override
public void onCancel() 
{
    Toast.makeText(AchievementActivity.this,"onCancel",Toast.LENGTH_LONG);
}

@Override
public void onClick(View v)
{
    if (v == facebookPostButton)
    {
        facebook = new Facebook("my_facebook_api");
        // replace APP_API_ID with your own
        facebook.authorize(this,new String[] {"publish_stream","read_stream","offline_access"},this); 
    }
}

private String getDefaultPost(String defaultTitleString) 
{
    //do some stuff here to get a string to post to wall

    return defaultPost;
}

private String getAchievementTextTodisplay(String achievementTitleString) {
    String achievementTextTodisplay = "DEFAULT";

    //do some stuff here to get text to display in the activity
            //this has nothing to do with the facebook post...

    return achievementTextTodisplay;
}

}

Logcat告诉我这个：

编辑
：在过去一年中必须在多台机器上安装Android开发平台并且在创建新的开发环境后总是遇到Facebook的问题,我发现这个简单的答案可能是Facebook实现在一个设备上工作的原因不是另一个……

秘密的Facebook API密钥(您在developer.facebook.com上列出的密钥)对于您使用不同证书打包的每个版本的应用程序都会有所不同.例如,假设您有两台开发机器.由于这两台计算机都将使用不同的证书构建您的应用程序,因此您必须确保为每台计算机生成一个Facebook API密钥,并将它们列在developer.facebook.com上.

这是因为当您登录Facebook帐户时,您的登录会话将在设备中创建.完成任务后,您必须从Facebook注销.
