Facebook的生成Keyhash爲Android

Question

我在與生成FB一keyhash， 需要OpenSSL和一個漫長的過程的傳統方式的麻煩......

我想知道如果我可以只輸入28隨機字符和使用該字符串作爲我的keyhash？ 。

Answer 1

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

    } catch (NoSuchAlgorithmException e) { 

    } 

Answer 2

//Call this method for KeyHash 
    String keyHash = getKeyHashForFacebook(SplashScreen.this); 
    Log.e("keyHash ", keyHash); 


    public static String getKeyHashForFacebook(Context context) { 
      try { 
       PackageInfo info = context.getPackageManager().getPackageInfo(
         context.getApplicationContext().getPackageName(), PackageManager.GET_SIGNATURES); 
       for (Signature signature : info.signatures) { 
        MessageDigest md = MessageDigest.getInstance("SHA"); 
        md.update(signature.toByteArray()); 
        return "KeyHash:" + context.getApplicationContext().getPackageName() + "=>" 
          + Base64.encodeToString(md.digest(), Base64.DEFAULT); 
       } 
      } catch (Exception e) { 
    e.printStackTrace(); 

      } 
      return "=>"; 
     }
