androidx.work.impl.WorkManagerInitializer:java.lang.ClassNotFoundException:"androidx.work.impl.WorkManagerInitializer"在路径上:/data/app/app-2.apk [英] androidx.work.impl.WorkManagerInitializer: java.lang.ClassNotFoundException: "androidx.work.impl.WorkManagerInitializer" on path: /data/app/app-2.apk

问题描述

我最近将旧应用的后台服务迁移到了 WorkManager .在最新的设备(包括到 sdk 22 )上，它看起来不错，可以运行重复的工作单元，甚至可以按预期在设备重新启动后安排它们.

I recently migrated my old app's background services to WorkManager. On recent devices (down to sdk 22 included) it looks OK, running repeating work units and scheduling them even across device reboots as expected.

问题是当我针对旧版本(此处的旧版本非常相关)(即我的 minSdkVersion )Android sdk 14进行测试时.BTW WorkManager 也应该具有相同的功能:向后兼容API 14 (根据

The problem is when I test against old version (old is very relative here), Android sdk 14 which is my minSdkVersion. BTW also WorkManager should have the same: Backwards compatible up to API 14 according to doc. As stated in title, error I get is:

 java.lang.RuntimeException: Unable to get provider androidx.work.impl.WorkManagerInitializer: java.lang.ClassNotFoundException: Didn't find class "androidx.work.impl.WorkManagerInitializer" on path: /data/app/com.example.myapp.apk
    at android.app.ActivityThread.installProvider(ActivityThread.java:4822)

我没有任何自定义WorkManager配置/初始化，我只是添加了

I don't have any custom WorkManager configuration/initialization, I simply added

     implementation 'androidx.work:work-runtime:2.2.0'

非常了解我的模块，并典型地使用它来安排后台操作.

to my module's gradle and used it quite typcally to schedule background operations.
