android - 使用 Android SDK 3.0 的 Facebook 登录导致 ANR 或根本不工作

标签 android facebook-android-sdk

为了让用户在 Android 应用程序中登录 Facebook，我尝试使用以下代码。用户登录后，应获取他们所有 friend 的位置。

不幸的是，这段代码有时会导致 ANR(如 Google Play 开发者控制台中所报告的那样)，有时甚至无法正常工作。如果我在 Facebook 中删除应用程序(撤销权限)，权限对话框将在下次启动 Android 应用程序时再次显示。但是，如果该应用程序已经拥有权限，它会导致这些 ANR 或只是没有成功地退出。

似乎部分工作正常，部分错误，不是吗？以下代码是登录和获取数据的正确方法吗？

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);
    }

}

我还将应用程序的 key 散列添加到 Facebook，包括调试和生产。不确定填充 = 是否也必须写入。

我无法遵循 Facebook 的官方教程，因为我不会使用 SDK 的登录按钮，也不会在 Android 中使用 fragment 。

编辑(2013 年 1 月 7 日):

在 Hartok 之后建议在回调的 call() 方法中将 session.isOpened() 替换为 state.isOpened()，50% 的情况都有效现在试运行。尽管如此，还是存在一些问题。在某些情况下，一切正常，在其他一些情况下(没有我做任何不同的事情)，LogCat 中出现以下错误:

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)

是什么导致了这个错误？客户端问题还是服务器问题？顺便说一句，此后应用程序似乎卡住 (ANR)。

如果我尝试按顺序连接两次，我会看到以下 LogCat 输出:

java.lang.IllegalStateException: Cannot execute task: the task is already running.
at android.os.AsyncTask.executeOnExecutor(AsyncTask.java:550)

at com.facebook.Request.executeBatchAsync(Request.java:1073)
at com.facebook.Request.executeBatchAsync(Request.java:1055)
at com.facebook.Request.executeAsync(Request.java:852)

这是为什么呢？为什么任务还在运行？

最佳答案

Log in attempt aborted 被触发，因为 Session.setActiveSession() 在上一个 session 当前打开时被调用。

是否可以调用 Session.setActiveSession() 两次？

你可以试试这段代码。未经测试，但部分来自 SessionLoginSample。

private static Session openActiveSession(Activity activity, boolean allowLoginUI, StatusCallback callback, List<String> permissions, Bundle savedInstanceState) {

    OpenRequest openRequest = new OpenRequest(activity).setPermissions(permissions).setLoginBehavior(SessionLoginBehavior.SSO_WITH_FALLBACK).setCallback(callback).setDefaultAudience(SessionDefaultAudience.FRIENDS);

    Session session = Session.getActiveSession();
    if (session == null) {
        if (savedInstanceState != null) {
            session = Session.restoreSession(this, null, fbStatusCallback, savedInstanceState);
        }
        if (session == null) {
            session = new Session(this);
        }
        Session.setActiveSession(session);
        if (session.getState().equals(SessionState.CREATED_TOKEN_LOADED) || allowLoginUI) {
            session.openForRead(openRequest);
            return session;
        }
    }

    return null;
}
