編程嘗試，因爲在Getting Started Android SDK指出：

public void generateFBKeyHash(Context mContext) { 
     try { 
      PackageInfo info = mContext.getPackageManager().getPackageInfo(
        "YOUR PACKAGE NAME IN YOUR MANIFEST", 
        PackageManager.GET_SIGNATURES); 

      for (Signature signature : info.signatures) { 
       MessageDigest md = MessageDigest.getInstance("SHA"); 
       md.update(signature.toByteArray()); 
       Log.e("fb key hash", Base64.encodeToString(md.digest(), Base64.DEFAULT)); 
      } 
     } catch (PackageManager.NameNotFoundException | NoSuchAlgorithmException e) { 
      Log.e("failed", e.getMessage()); 
     } 
    }
