我正在尝试将Google Places AutoComplete API添加到我的Android Instant Apps项目中。
我按照this sample来实施API。

配置中运行项目时，它可以正常运行。
但是当我在app配置中运行它时会抛出这个：

错误代码的解释：
客户端尝试从未通过的API调用方法 连接。可能的原因包括：
- 以前无法使用可解析的错误连接API，但用户拒绝了解决方案。
- 该设备不支持GmsCore。
- 特定API无法在此设备上连接。
我在模拟器上更新了Google Play服务（它的11.7.46（470-175121617）BTW），但它没有改变任何内容。
我将我的Google Play服务依赖项放入API_NOT_CONNECTED模块。我检查了合并的清单文件，它们都有Google Play API密钥。
在Android Developers site他们在支持的 API列表中列出了Google Places API。
我在其他功能模块中使用Google Location API，它在base和app配置中都有效。
那我在这里做错了什么？
答案 0 :(得分：0)
我决定使用GoogleApiClient连接API：
GoogleApiClient.Builder(this)
.enableAutoManage(this, this)
.addApi(Places.GEO_DATA_API)
.build()
.connect()
但在API_UNAVAILABLE配置中，连接尝试失败，状态代码为instantapp。
在docs中，API_UNAVAILABLE表示该API不适用于即时应用：
调试使用Google Play服务库的即时应用时 除了上面列表中包含的那些，你可能会看到 调试输出中的API_UNAVAILABLE错误。 API_UNAVAILABLE 错误表示该库尚未适应使用 Android即时应用。
所以我删除了地方自动完成功能，并继续使用类似geocoding的内容。
