Question

我尝试将数据从Firebase数据库检索到我的回收站视图，无论我尝试什么，我都会收到此错误。我该如何解决这个问题？

在我的模拟器中，Google Play服务版本为：11.5.80 我没有物理Android设备，因此我没有在真实设备上进行测试。我尝试更新我的模拟器，但没有可用于模拟器的更新。

Discarding data. Failed to send app launch
Failed to get app instance id
Failed to send current screen to service
Discarding data. Failed to send event to service

Logcat也说Google Play services out of date。

看起来您正在尝试使用API 27仿真器映像运行。目前（1月14日）尚未发布支持Firebase / Google Play版本11.8.0的API 27模拟器映像。

您的选择是使用API 26仿真器映像运行，或降级构建中的库版本：

compileSdkVersion 26
...
targetSdkVersion 26
...
// for all Support Libs, use 26.1.0
...
implementation 'com.google.firebase:firebase-database:11.4.2'
implementation 'com.firebaseui:firebase-ui-database:3.1.0'
