我正在使用带有通知的前台服务。我在主活动的onDestroy方法中通过调用stopForeground和stopService删除了该服务。问题是,当我把我的应用程序从最近的应用程序中删除时,调试会话仍在运行,当我重新启动应用程序时,MyApplication的onCreate方法与Application类的扩展没有调用。
我在这里看到了答案 https://stackoverflow.com/a/53334788/10069542
<service
android:enabled="true"
android:name=".ExampleService"
android:exported="false"
android:stopWithTask="true" />
当我写android:stopWithTask="true "时,它在android OS 9及以下版本中工作正常,但在android OS 10版本中不工作。
奇怪的是,当我写android:stopWithTask="false "时,它在android OS版本10中工作正常,但在任何其他版本中都不工作。
