Facebook发布key_hash

Question

我有生成密钥哈希的问题。 我使2键：

C:\openssl\bin>"C:\Program Files\Java\jre7\bin\keytool.exe" -exportcert -alias forumurology -keystore uroweb7228.keystore | openssl sha1 -binary | openssl base64 
Enter keystore password: ******* 
c/6e5fY8Rg3Gshn1TKucia***/A= 

C:\openssl\bin>"C:\Program Files\Java\jre7\bin\keytool.exe" -exportcert -alias a 
ndroiddebugkey -keystore debug.keystore | openssl sha1 -binary | openssl base64 
Enter keystore password: android 
3L0oeMh7uk9YWE0sYavUuT***yU= 

然后将其保存到我的Facebook应用程序设置。 当我运行释放的apk，我有错误：

10-21 16:48:11.583: W/fb4a(:<default>):BlueServiceQueue(20097): Exception during service 
10-21 16:48:11.583: W/fb4a(:<default>):BlueServiceQueue(20097): com.facebook.http.protocol.ApiException: Key hash ypC1--aybTSQXdzXGLtM-_nXydI does not match any stored key hashes.

Answer 1

这是因为该设备是创建一个新的密钥散列这是不是在你的应用程序设置。所以你必须相应地更新keyhash ..使用onCreate（）

try { 
      PackageInfo info = getPackageManager().getPackageInfo("YOUR_PACKAGE_NAME", PackageManager.GET_SIGNATURES); 
      for (Signature signature : info.signatures) { 
       MessageDigest md = MessageDigest.getInstance("SHA"); 
       md.update(signature.toByteArray()); 
       Log.d("KeyHash:", Base64.encodeToString(md.digest(), Base64.DEFAULT)); 
       } 
     } catch (NameNotFoundException e) { 

     } catch (NoSuchAlgorithmException e) { 

     }
