推荐答案

对于Windows用户获得从OpenSSL的关键，可能会非常棘手，有些时候..我总是用它来寻找合适的  签名..只是复制粘贴此code在你的onCreate（）和运行。

For windows users getting the key from openssl, may be tricky some times.. I always use this to find the right signature.. Just paste this code in your onCreate() and run.

 // Add code to print out the key hash
  try {
  PackageInfo info = getPackageManager().getPackageInfo(getPackageName(), PackageManager.GET_SIGNATURES);
  for (Signature signature : info.signatures) {
  MessageDigest md = MessageDigest.getInstance("SHA");
  md.update(signature.toByteArray());
  Log.e("MY KEY HASH:", Base64.encodeToString(md.digest(), Base64.DEFAULT));
      }
  } catch (NameNotFoundException e) {

  } catch (NoSuchAlgorithmException e) {

  }
