android - 只能通过一个帐户登录，不能使用另一个ID登录Facebook

Question

在我的应用程序中，我可以通过我的 facebook id 登录。我输入另一个 id，它没有像我的 id 那样获取数据。我不明白这是什么问题。当我输入另一个 id 时，它显示正在加载，之后只能看到空白的 Facebook 页面。

主 Activity

public class MainActivity extends Activity {
    Facebook fb;
Button login,getData,logout;    
ImageView ig;
String app_id;
private AsyncFacebookRunner mAsyncRunner;

private SharedPreferences mPrefs;
SharedPreferences.Editor editor;
    @Override
    protected void onCreate(Bundle savedInstanceState) {
        super.onCreate(savedInstanceState);
        setContentView(R.layout.fragment_main);
     app_id= getString(R.string.app_id);
     fb= new Facebook(app_id);
        login=(Button) findViewById(R.id.login);
        logout=(Button) findViewById(R.id.logout);
        getData=(Button) findViewById(R.id.getData);
        // ig= (ImageView) findViewById(R.id.profile_pic);
         login.setOnClickListener(new View.OnClickListener() {

                @Override
                public void onClick(View v) {
                    loginToFacebook();
                }
            });

getData.setOnClickListener(new View.OnClickListener() {

    @Override
    public void onClick(View v) {
        getProfileInformation();
    }
});
     logout.setOnClickListener(new View.OnClickListener() {

@Override
public void onClick(View v) {
    if(fb.isSessionValid()){
        logoutFromFacebook();
    }

}
});
mAsyncRunner = new AsyncFacebookRunner(fb);
//updateButtonImage();
try {

    PackageInfo info = getPackageManager().getPackageInfo(getPackageName(), PackageManager.GET_SIGNATURES);

    for (Signature signature : info.signatures)
    {
     MessageDigest md = MessageDigest.getInstance("SHA");
     md.update(signature.toByteArray());
     Log.d("KeyHash:", Base64.encodeToString(md.digest(), Base64.DEFAULT));
    }

   } catch (NameNotFoundException e) {
    Log.e("name not found", e.toString());
   } catch (NoSuchAlgorithmException e) {
    Log.e("no such an algorithm", e.toString());
   }    
    }

我遇到了同样的问题。我是这样修好的。

前往 Facebook 开发者页面

Apps --> "YourApp"--> Status and Review --> Enable(“你想让这个应用程序及其所有实时功能对公众开放吗？”)

像这样
