第一步： 创建secrets.xml文件， 并保存密钥
    <!-- Inside of `res/values/secrets.xml` -->
    <?xml version="1.0" encoding="utf-8"?>
    <resources>
        <string name="parse_application_id">xxxxxx</string>
        <string name="parse_client_secret">yyyyyy</string>
        <string name="google_maps_api_key">zzzzzz</string>
    </resources>

第二步： 使用密钥，AS会自动将文件并入项目，可以直接当String是使用
