Question

我正在构建一个应用程序，它将支持facebook.I已下载facebook API 3.6.0
问题在于登录 - 如果手机上没有安装原始FB应用程序，登录将通过自定义对话框一切正常，但如果安装了FB应用程序，登录将通过自定义对话框并自动重定向到原始FB应用程序，没有发生任何事情。我已经在不同的手机上测试了这个，并且总是同样的问题。

我用这个link来生成哈希键。在我的facebook-sdk 3.6.0中我找不到： private static boolean ENABLE_LOG = false至true。

任何人都可以提供帮助？登录活动代码：

    public class Login extends Activity {
SessionManager session;
EditText etLoginusername;
EditText etLoginPass;
String cus_email, cus_pass, cus_id, cus_mob, cus_name, cus_points, success,
        fb_id, id;
Button btnLogin, btnForgotPass, btnfblogin;
ToggleButton remToggle;
int REM_STATUS;
public static Facebook fb;
SharedPreferences sp;

    btnfblogin = (Button) findViewById(R.id.Bfb);
    btnfblogin.setOnClickListener(new View.OnClickListener() {
        @Override

            // fb login code start
            String APP_ID = getString(R.string.APP_ID);
            fb = new Facebook(APP_ID);

            String access_token = sp.getString("access_token", null);
            long expires = sp.getLong("access_expires", 0);
            if (access_token != null) {
                fb.setAccessToken(access_token);
            }

这应该暂时解决它

fb.authorize(Login.this, new String[] { "email" },Facebook.FORCE_DIALOG_AUTH,              new DialogListener()

Facebook API 3.6.0登录失败，手机上安装了FB应用程序
