在Linux OS(Ubuntu)中生成发布密钥哈希：Android Facebook SDK

如何在Ubuntu中生成正确的发布密钥哈希？
我已经提到了 this,但我无法得到答案.

解决方法

尝试了很多次后,我得到片段的解决方案,给我一个释放密钥哈希.

try {
        PackageInfo info = getActivity().getPackageManager().getPackageInfo(
                "com.yourappname.app",PackageManager.GET_SIGNATURES);
        for (Signature signature : info.signatures) {
            MessageDigest md = MessageDigest.getInstance("SHA");
            md.update(signature.toByteArray());
            Log.d("KeyHash","KeyHash:" + Base64.encodetoString(md.digest(),Base64.DEFAULT));
            Toast.makeText(getActivity().getApplicationContext(),Base64.encodetoString(md.digest(),Base64.DEFAULT),Toast.LENGTH_LONG).show();
        }
    } catch (PackageManager.NameNotFoundException e) {

    } catch (NoSuchAlgorithmException e) {

    }

我从here获得了终端的这个命令,它给了我释放密钥哈希.

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