[移动开发]Context.startForegroundService() did not then call Service.startForeground() 崩溃问题

问题:

android.app.RemoteServiceException
Context.startForegroundService() did not then call Service.startForeground()
android.app.ActivityThread$H.handleMessage(ActivityThread.java:2002)
android.os.Handler.dispatchMessage(Handler.java:106)
android.os.Looper.loop(Looper.java:192)
android.app.ActivityThread.main(ActivityThread.java:6893)
java.lang.reflect.Method.invoke(Native Method)
com.android.internal.os.RuntimeInit$MethodAndArgsCaller.run(RuntimeInit.java:549)
com.android.internal.os.ZygoteInit.main(ZygoteInit.java:875)

分析:
使用startForegroundService必须在5秒之内startForeground一下

解决方案:

//在启动的service里调用一下startForeground方法,2021这个值看你自己需求,0除外
startForeground(2021, new Notification());
