Question

我的应用程序可以在许多设备上运行，但是当我尝试在像kitkat这样的低设备上构建或运行时 - 并降低它会抛出此错误：

java.lang.RuntimeException：无法获取提供者com.google.firebase.provider.FirebaseInitProvider：java.lang.ClassNotFoundException：com.google.firebase.provider.FirebaseInitProvider

这是我的傻瓜..

您过早应用了播放服务插件，将其放在gradle文件的末尾：

android {
   ...
}

dependencies {
   compile 'com.android.support:multidex:1.0.1'
}

plugin: 'com.google.gms.google-services'
