无效的键哈希facebook android sdk [英] Invalid Key hash facebook android sdk

问题描述

我正在尝试使用Facebook Android SDK开发一个简单的应用程序与Facebook登录按钮。但是我有麻烦的钥匙哈希。我创建了一个调试键和一个发行键：（在Mac中）

调试键：

  keytool -exportcert -alias androiddebugkey -keystore〜/ .android / debug.keystore | openssl sha1 -binary | openssl base64 
 
 keytool -exportcert -alias< RELEASE_KEY_ALIAS> -keystore< RELEASE_KEY_PATH> | openssl sha1 -binary | openssl base64 
  

我也试过这个代码也是

  public static void showHashKey（Context context）{
 try {
 PackageInfo info = context.getPackageManager（）。getPackageInfo（
com.example。我，PackageManager.GET_SIGNATURES）; //你的包名是
（签名签名：info.signatures）{
 MessageDigest md = MessageDigest.getInstance（SHA）; 
 md.update（signature.toByteArray（））; 
 Log.i（KeyHash），Base64.encodeToString（md.digest（），Base64.DEFAULT））; 
} 
} catch（NameNotFoundException e）{
} catch（NoSuchAlgorithmException e）{
} 
} 
  pre> 
 
 
然后我在Facebook Developers页面中复制了这个关键散列。当我用eclipse运行我的应用程序然后工作。但是当我导出apk并将其复制到设备不工作。 
我也有另一个问题。如果我的divice已经安装了Facebook应用程序，那么也不工作。 
我如何解决我的问题？
解决方案
当您获得无效的密钥哈希时，它还显示正确的密钥哈希并说键盘XXXXX不匹配任何存储的键盘。所以拷贝显示的keyhash，并在末尾附加=作为XXXXX =，并将其添加到密钥哈希部分。希望它可以工作....  
 
 
 
这可能也会工作
  public static void showHashKey（Context context）{
 try {
 PackageInfo info = context.getPackageManager（）。getPackageInfo（
com.example.me，PackageManager.GET_SIGNATURES）; //你的包名是
（签名签名：info.signatures）{
 MessageDigest md = MessageDigest.getInstance（SHA）; 
 md.update（signature.toByteArray（））; 
 Log.i（KeyHash），Base64.encodeToString（md.digest（），Base64.DEFAULT））; 
} 
} catch（NameNotFoundException e）{
} catch（NoSuchAlgorithmException e）{
} 
}

I'm trying to use Facebook Android SDK to develop a simple app with the Facebook Login Button. But i'm having trouble with Key Hashes. I've created both a debug key and a release key:(in mac)

Debug key:
keytool -exportcert -alias androiddebugkey -keystore ~/.android/debug.keystore | openssl sha1 -binary | openssl base64

keytool -exportcert -alias <RELEASE_KEY_ALIAS> -keystore <RELEASE_KEY_PATH> | openssl sha1 -binary | openssl base64
i also  tryed this code also
public static void showHashKey(Context context) {
        try {
            PackageInfo info = context.getPackageManager().getPackageInfo(
                    "com.example.me", PackageManager.GET_SIGNATURES); //Your            package name here
            for (Signature signature : info.signatures) {
                MessageDigest md = MessageDigest.getInstance("SHA");
                md.update(signature.toByteArray());
                Log.i("KeyHash:", Base64.encodeToString(md.digest(), Base64.DEFAULT));
                }
        } catch (NameNotFoundException e) {
        } catch (NoSuchAlgorithmException e) {
        }
    }
And then i copied this key hashes in the Facebook Developers page.when i run my app with eclipse then  working.but When i export the apk and copy it into the device it does not working.
also i have another problem.if my divice  has installed Facebook Application then also not working.
how i can solve my problem?

When you get Invalid key hash, it also shows the correct key hash and says "The keyhash XXXXX didnot match with any of the stored keyhashes" . so copy that displayed keyhash and append "=" at the end as XXXXX= and add it in the key hash section. Hope it works....

this might also work
public static void showHashKey(Context context) {
    try {
        PackageInfo info = context.getPackageManager().getPackageInfo(
                "com.example.me", PackageManager.GET_SIGNATURES); //Your package name here
        for (Signature signature : info.signatures) {
            MessageDigest md = MessageDigest.getInstance("SHA");
            md.update(signature.toByteArray());
            Log.i("KeyHash:", Base64.encodeToString(md.digest(), Base64.DEFAULT));
            }
    } catch (NameNotFoundException e) {
    } catch (NoSuchAlgorithmException e) {
    }
}
