Inicio de sesión de Facebook con Android SDK 3.0 que provoca ANR o no funciona en absoluto

Para registrar un usuario en Facebook en una aplicación para Android, intento utilizar el siguiente código. Una vez que el usuario ha iniciado sesión, todas las ubicaciones de sus amigos deben ser buscadas.

Desafortunadamente, este código causa ANRs a veces (como se indica en la consola de desarrolladores de Google Play) ya veces simplemente no funciona. Si quito la aplicación dentro de Facebook (revocar permisos), el permiso de diálogo se muestra de nuevo en el próximo lanzamiento de la aplicación para Android. Pero si la aplicación tiene los permisos ya, hace que los ANRs o simplemente se cierra sin éxito.

• El inicio de sesión de Android facebook no funciona con la aplicación de Facebook instalada
• El contenido de Dialog de Android Facebook Share no se muestra en la página principal
• Facebook android sdk 3.0 SSO
• Excepción inesperada de nivel superior en android-support-v4.jar
• Android - Facebook SDK 3 - Cómo iniciar sesión mediante programación sin LoginButton

Parece que las partes están funcionando y las partes están equivocadas, ¿no? ¿Es el código siguiente una forma correcta de iniciar sesión y obtener datos?

package com.my.application; import java.util.Arrays; import java.util.List; import org.json.JSONArray; import org.json.JSONObject; import android.app.Activity; import android.app.ProgressDialog; import android.content.Intent; import android.os.Bundle; import android.preference.PreferenceManager; import com.facebook.*; import com.facebook.Session.OpenRequest; import com.facebook.Session.StatusCallback; public class FBLocations extends Activity { private Session.StatusCallback fbStatusCallback = new Session.StatusCallback() { @Override public void call(Session session, SessionState state, Exception exception) { // callback for session state changes if (state.isOpened()) { Request.executeGraphPathRequestAsync(session, "me/friends/?access_token="+session.getAccessToken()+"&fields=id,name,location&limit=500", new Request.Callback() { @Override public void onCompleted(Response response) { if (response != null) { // do something with <response> now } } }); } } }; protected void onCreate(Bundle savedInstanceState) { super.onCreate(savedInstanceState); try { openActiveSession(this, true, fbStatusCallback, Arrays.asList("friends_location")); } catch (Exception e) { e.printStackTrace(); } } private static Session openActiveSession(Activity activity, boolean allowLoginUI, StatusCallback callback, List<String> permissions) { OpenRequest openRequest = new OpenRequest(activity).setPermissions(permissions).setLoginBehavior(SessionLoginBehavior.SSO_WITH_FALLBACK).setCallback(callback).setDefaultAudience(SessionDefaultAudience.FRIENDS); Session session = new Session.Builder(activity).build(); if (SessionState.CREATED_TOKEN_LOADED.equals(session.getState()) || allowLoginUI) { Session.setActiveSession(session); session.openForRead(openRequest); return session; } return null; } @Override public void onActivityResult(int requestCode, int resultCode, Intent data) { super.onActivityResult(requestCode, resultCode, data); Session.getActiveSession().onActivityResult(this, requestCode, resultCode, data); } } 

También he añadido hashes clave de la aplicación a Facebook, tanto de depuración y producción. No estaba seguro de si el relleno = tiene que ser escrito también.

No pude seguir el tutorial oficial de Facebook, ya que no usaré el botón de inicio de sesión del SDK ni tampoco usaré fragmentos en Android.

Edición (7 de enero de 2013):

Después de que Hartok sugirió reemplazar session.isOpened() por state.isOpened() en el método call() callback, las cosas funcionan en el 50% de todas las pruebas ahora. Sin embargo, hay algunos problemas. En algunos casos, todo funciona bien, en algunos otros casos (sin que yo haga nada diferente), hay el siguiente error en LogCat:

 01-07 01:55:29.882: W/System.err(30572): com.facebook.FacebookException: Log in attempt aborted. at com.facebook.Session.close(Session.java:572) at com.facebook.Session.setActiveSession(Session.java:755) at my.app.package.FBImport.openActiveSession(FBImport.java:145) // this is: Session.setActiveSession(session); at my.app.package.FBImport.access$5(FBImport.java:139) at my.app.package.FBImport$4.run(FBImport.java:124) 

¿Qué causa este error? ¿Problema del cliente o problema del servidor? La aplicación parece congelarse (ANR) después de eso, por cierto.

Y si trato de conectar dos veces en secuencia, veo la siguiente salida LogCat:

 java.lang.IllegalStateException: Cannot execute task: the task is already running. at android.os.AsyncTask.executeOnExecutor(AsyncTask.java:550) at android.os.AsyncTask.execute(AsyncTask.java:511) at com.facebook.RequestAsyncTask.executeOnSettingsExecutor(RequestAsyncTask.java:186) at com.facebook.Request.executeBatchAsync(Request.java:1094) at com.facebook.Request.executeBatchAsync(Request.java:1073) at com.facebook.Request.executeBatchAsync(Request.java:1055) at com.facebook.Request.executeAsync(Request.java:852) 

¿Porqué es eso? ¿Por qué sigue funcionando la tarea?
