Facebook SSO示例不工作 - “出现错误。请稍后重试“ [英] Facebook SSO example not working - "An error ocurred. Please try again later"

问题描述

我正在尝试将facebook整合到我的应用程序中，因此遵循了本教程： Facebook Android ，但我无法获得第一个例子（单点登录）工作。当我的应用加载时，我会收到Facebook对话框，但它只是说发生错误，请稍后再试。在底部有一个Facebook风格的Ok按钮，在logcat中没有任何内容：

I'm trying to integrate facebook into my app and so have followed the tutorial at: Facebook Android but I can't get the first example (Single Sign-On) to work. When my app loads up I get the facebook dialog but it just says "An error occurred. Please try again later." with a facebook-style "Ok" button at the bottom and there is nothing in logcat:

我按照教程中的步骤进行操作，但是我猜测这个API ID或者keytool生成的hashkey有问题。以下是我遵循的步骤：

I followed the steps in the tutorial but I'm guessing there is something wrong with the APP ID or the hashkey generated by keytool. Here are the steps I followed:

1. 克隆fb git。


2. 创建fbSDK项目。 li>
   
3. 创建自己的fb项目并将fbSDK作为库链接。


4. 然后我用openssl输入了keytool cmd，并输入了密码android，如


5. 我去了developers.facebook.com并创建了一个新的应用程序。


6. 在编辑设置 - >手机和设备我把哈希放在提供的框中。


7. 在编辑设置 - >手机和设备中，我选择了本机应用程序作为应用程序类型


8. 回到应用程序我复制并粘贴SSO示例代码。


9. 我将Facebook（）构造函数中的YOUR_APP_ID更改为developers.facebokk.com上显示的APP ID我的新应用程序页面


10. 我在手机上运行了应用程序。

1. clone fb git.
2. create fbSDK project.
3. create own fb project and link the fbSDK as a library.
4. I then did the keytool cmd with openssl and input the password "android" as suggested by others on stackoverflow.
5. I went to developers.facebook.com and created a new app.
6. In "Edit Settings->Mobile and Devices" I put my hash in the box provided.
7. In "Edit Settings->Mobile and Devices" I chose "Native App" as "Application Type"
8. Back in the app I copy and pasted the SSO example code.
9. I changed the "YOUR_APP_ID" in the Facebook() constructor to the APP ID shown on the developers.facebokk.com page for my new app.
10. I ran the app on my phone.

不知道为什么在logcat中没有什么，但是当我安装它时，控制台总是在没有失败的情况下说： ActivityManager：Warning：Activity没有启动，它的当前任务已经被带到前端

I don't know why there is nothing in logcat but when I install it, the Console always, without fail, says the:ActivityManager: Warning: Activity not started, its current task has been brought to the front

我找不到任何logcat引用到我的应用程序或错误我从Facebook sdk得到的是： Facebook-ProxyAuth（4828）：无法读取呼叫包的签名。

And I can't find any logcat reference to my app or the error I was getting from the facebook sdk which was: Facebook-ProxyAuth(4828): Failed to read calling package's signature.

我已经在这几个小时了，任何帮助将不胜感激。我不敢相信Facebook的SDK和帮助是如此粗略的Android，Facebook应该为自己感到羞耻。

I have been at this for a few hours now and any help would be greatly appreciated. I can't believe the facebook SDK and help is so sketchy for Android, facebook should be ashamed of themselves.

谢谢，

推荐答案

其实我遇到了同样的问题，它解决了。
因此，在哈希密钥生成中使用以下步骤：

In fact I have encountered the same problem exactly and it solved. So, in the hash key generation use the following steps:

1. 打开cmd并转到您的Android SDK路径。 li>
   
2. 键入以下命令：
   keytool -exportcert -alias androiddebugkey -keystore [您的SDK路径|例如c：\users\user] .android\debug.keystore | openssl sha1 -binary | openssl base64


3. 之后，密码输入android


4. 将结果复制到您的Facebook应用设置并保存设置。


5. 在您的Android应用程序中使用Facebook应用程序ID（而不是Android哈希键）。

1. open cmd and go to your android SDK path.
2. type this command : keytool -exportcert -alias androiddebugkey -keystore [your SDK path | e.g c:\users\user].android\debug.keystore | openssl sha1 -binary | openssl base64
3. after that it's promet for password enter "android"
4. copy the result to your facebook app settings and save settings.
5. in your android app use the facebook app id(not the android hash key).
