Answer 1

**If your minSdkVersion is set to 21 or higher, all you need to do is set multiDexEnabled to true in your module-level build.gradle file, as shown here:**
android {
defaultConfig {
    ...
    minSdkVersion 21 
    targetSdkVersion 25
    multiDexEnabled true
}``
...

}

依赖项{compile'com.android.support:multidex:1.0.1'}

 public class MyApplication extends MultiDexApplication { ... }

应用程序扩展了一些hotherapplication { @override受保护 void attachbasecontext（上下文基础）{ super.attachbasecontext（base）; 多端。install（this）;}}

Answer 2

JobScheduler并未备份，但是，有firebase jobdispatcher支持相同的API，并通过Google Play Services进行了支持。

firebase jobdispatcher是一个用于安排背景作业的库 在您的Android应用中。它提供了一个与Jobscheduler兼容的API 在所有最新版本的Android（API 9级以上）上都有工作 安装了Google Play服务。

Answer 3

edit：op由于答案而突变了这个问题，所以这个答案确实没有更长的申请。

android.app.job.JobScheduler类在API级别21（Android 5.0）中添加。因此，很明显，该应用将在较早的Android版本上崩溃。
