我目前正在尝试使用Retrofit2设置Room.我想将数据从Retrofit2插入到Room数据库中,但插入对我来说不起作用,应用程序崩溃了.我使用Room library实现了三个组件：实体,Dao和数据库.

我有结果这个错误.

}

解决方法:

我只是将gradle依赖项设置为最新版本并且可以正常工作.

的build.gradle(项目级)

dependencIEs {    classpath 'com.androID.tools.build:gradle:3.3.1'    classpath 'com.Google.gms:Google-services:4.2.0'}

的build.gradle(应用级)

dependencIEs {    implementation 'com.Google.firebase:firebase-core:16.0.7'    implementation 'com.Google.firebase:firebase-messaging:17.4.0'    implementation 'com.Google.androID.gms:play-services-location:16.0.0'}
