Google 地方 API 而不是 working.Authentication 在服务器上失败
Google Places API not working.Authentication failed on the server
我正在使用 Google 第一个地方 API time.I 想在一个受限的地方显示附近的公用设施（比如医院） radius.When 我点击"find button " 什么都没有 happens.I 我正在使用这个 link 来开发这个项目：link 我已经正确地生成了 Google Places API 键，但它总是显示以下错误：
Authentication failed on the server.
E/Google Maps Android API: Authorization failure. Please see https://developers.google.com/maps/documentation/android/start for how to correctly set up the map.
E/Google Maps Android API: In the Google Developer Console (https://console.developers.google.com) Ensure that the "Google Maps Android API v2" is enabled. Ensure that the following Android Key exists: API Key: AIzaSyA4NL7****************************
