Facebook的Android应用程序错误：无效的密钥哈希 [英] Facebook android app error : Invalid key hash

问题描述

我已经将Facebook SDK导入到我的android项目中，第一次从我的android应用程序登录到Facebook，但第二次出现此错误：

< blockquote>

密钥散列无效。密钥哈希...与任何存储的密钥
散列不匹配。在
配置您的应用程序密钥哈希 http://developers.facebook.com/apps/ ..

我也尝试输入他们在这个错误中提供的密钥，但它不起作用。

编辑：
我已经使用了cmd命令，它会生成一个密钥并要求输入密码为android

解决方案

据我所知，你已经得到了你的密钥哈希，但我仍然会在这里把代码放在控制台中。

  PackageInfo info; 
尝试{
 info = getPackageManager（）。getPackageInfo（com.your.project.package，PackageManager.GET_SIGNATURES）; 
（签名签名：info.signatures）{
 MessageDigest md; 
 md = MessageDigest.getInstance（SHA）; 
 md.update（signature.toByteArray（））; 
 String something = new String（Base64.encode（md.digest（），0））; 
 // String something = new String（Base64.encodeBytes（md.digest（）））; 
 Log.e（hash key，something）; 
} 
} catch（PackageManager.NameNotFoundException e1）{
 Log.e（name not found，e1.toString（））; 
} catch（NoSuchAlgorithmException e）{
 Log.e（no such an algorithm，e.toString（））; 
} catch（Exception e）{
 Log.e（exception，e.toString（））; 
} 
  

其中com.your.project.package 是你的项目包）=

接下来的事情，不要删除以前的关键哈希，他们不会发生冲突，我认为。例如，我在我的Facebook应用程序中有2个keyhashes。

最新的事情，我认为这是问题所在。在developers.facebook上转到您的应用的状态和审查。并将您的应用程序切换到公共。

I have imported the Facebook SDK to my android project, first time I logged in to Facebook from my android application it worked, but the second time I got this error :

Invalid key hash. The key hash "..." does not match any stored key hashes. Configure your app key hashes at http://developers.facebook.com/apps/..

I also tried to enter the key they provided in this error but it didn't work.

EDIT: I have used the cmd command to which it generates a key and asks for the password which is "android"

解决方案

As I understand you've got your key hash, but still I'll put here the code for getting it in the console.

PackageInfo info;
try {
    info = getPackageManager().getPackageInfo("com.your.project.package", PackageManager.GET_SIGNATURES);
    for (Signature signature : info.signatures) {
        MessageDigest md;
        md = MessageDigest.getInstance("SHA");
        md.update(signature.toByteArray());
        String something = new String(Base64.encode(md.digest(), 0));
        //String something = new String(Base64.encodeBytes(md.digest()));
        Log.e("hash key", something);
    }
} catch (PackageManager.NameNotFoundException e1) {
    Log.e("name not found", e1.toString());
} catch (NoSuchAlgorithmException e) {
    Log.e("no such an algorithm", e.toString());
} catch (Exception e) {
    Log.e("exception", e.toString());
}

Where "com.your.project.package" is the package of your project =)

Next thing, dont delete previous key hash, they don't conflict I think. For example I have 2 keyhashes in my facebook app.

And the latest thing, and I think this is the problem. Go to the Status&Review of your app at the developers.facebook. And switch your application to public.
