Answer 1

编辑：OP 改变了问题，因为它被回答了，所以这个答案没有不再申请。

class android.app.job.JobScheduler 已添加到 API 级别 21 (Android 5.0)。因此很明显，该应用程序会在较早的 Android 版本上崩溃。

Answer 2

JobScheduler 未向后移植，但是，Firebase JobDispatcher 支持相同的 API 并通过 Google Play Services.

向后移植

The Firebase JobDispatcher is a library for scheduling background jobs in your Android app. It provides a JobScheduler-compatible API that works on all recent versions of Android (API level 9+) that have Google Play services installed.

Answer 3

**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{编译'com.android.support:multidex:1.0.1'}

 public class MyApplication extends MultiDexApplication { ... }

Application extends SomeOtherApplication { @Override protected void attachBaseContext(Context base) { super.attachBaseContext(base); MultiDex.install(this); } }
