Facebook Connect 在模拟器/设备上的工作方式不同，但在 Google Play 上却不同 [英] Facebook Connect works different on emulator/device, but not on Google Play

问题描述

我的应用中出现了奇怪的 facebook 连接行为.如果我在模拟器中使用它，则在 facebook.authorize > onComplete 调用 facebook.request(检索用户数据)和 facebook.dialog(在墙上发布).但是如果我使用设备进行调试，这些调用需要在 onActivityResult() 才能工作.

I'm getting a weird facebook connect behavior in my app. If I use it in emulator, the calls for facebook.request (to retrieve user data) and facebook.dialog (to post on wall) are made at facebook.authorize > onComplete. But if I use a device for debugging, these calls need to be at onActivityResult() to work.

我已将经过设备测试的 apk 上传到 google play，但它不起作用！相同的代码，如果从 eclipse 安装，它可以工作......如果从 Play 下载，则不会！

And I've uploaded the device-tested apk into google play, but it doesn't works! The SAME code, if installed from eclipse, it works... if downloaded from Play, doesn't!

不起作用"是指在用户获得授权后不会调用 facebook.request 和 facebook.dialog，并且应用会卡在空白屏幕中.

by "doesn't works", I mean that facebook.request and facebook.dialog aren't called after user is authorized, and the app get stucked in a blank screen.

我的 facebook 连接活动:

my facebook connect activity:

public class FacebookConnectActivity extends Activity {
private static final String TAG_JSON = "json";
static Facebook facebook = new Facebook("111111111111111");
AsyncFacebookRunner mAsyncRunner;
private SharedPreferences mPrefs;
JSONObject json;
Context ctx = this;

@Override
protected void onCreate(Bundle savedInstanceState) {
    super.onCreate(savedInstanceState);
    setContentView(R.layout.resgatar_produto_layout);
    Log.w("FacebookConnect", "Activity Started");

    mPrefs = getPreferences(MODE_PRIVATE);
    String access_token = mPrefs.getString("access_token", null);
    long expires = mPrefs.getLong("access_expires", 0);
    if(access_token != null) {
        facebook.setAccessToken(access_token);

    }
    if(expires != 0) {
        facebook.setAccessExpires(expires);
    }

    if(!facebook.isSessionValid()) {

    facebook.authorize(this, new String[] {"email", "user_photos",     "user_birthday", "user_hometown", "user_relationships","user_location", "user_work_history",     "publish_actions"}, new DialogListener() {
        @Override

            Log.w("FacebookConnect", "User authorized");
            /*mAsyncRunner = new AsyncFacebookRunner(facebook);

推荐答案

Facebook Connect 是 SSO 流，完成后会回调 onActivityResult.你应该在那里处理响应

Facebook Connect is SSO flow, and when it is done onActivityResult is called back. you should handle the response in there

简单例子

@Override
    protected void onActivityResult(int requestCode, int resultCode, Intent data) {
        super.onActivityResult(requestCode, resultCode, data);

if (requestCode == AppContext.FACEBOOK_SSO_ACTIVITY_CODE) {

            // Successfully redirected.
            if (resultCode == Activity.RESULT_OK) {

                    // Check OAuth 2.0/2.10 error code.
                    String error = data.getStringExtra("error");
                    if (error == null) {
                        error = data.getStringExtra("error_type");
                    }
                    else {// SSO successful
                        String access_token = data.getStringExtra("access_token");
                        // from here on, you can do whatever you need
                     }
      }
}

另一方面，我建议两个实现这两个选项(sso 和 oauth 作为后备).这是 Facebook SSO 和 OAuth 的示例实现；https://github.com/wareninja/generic-oauth2-login-for-android

on the other hand, I suggest two implement both options (sso and oauth as fallback). here is an example implementation for both Facebook SSO and OAuth; https://github.com/wareninja/generic-oauth2-login-for-android
