我想使用Java Client for Google Maps Services从api方向获取结果。但是当我单击InfoWindoclick时，我的android studio出现致命异常：速率受限调度程序错误。请有人帮助我。我尝试解决此问题2天，但我没有解决。
我在Google上搜索以解决此问题并搜索stackoverflow，但是找不到任何可帮助我解决问题的解决方案。

答案 0 :(得分：1)
将以下行添加到项目的Gradle文件中
实现组：“ com.github.seratch”，名称：“ java-time-backport”，版本：“ 1.0.0”
确保在Google Cloud Project上启用计费功能
还应避免在Android上使用GoogleMapsServices库。在这里https://github.com/googlemaps/google-maps-services-java/blob/master/README.md#intended-usage-of-this-library
