4. Automatic Launch and Secondary Launch Service

   4.1 MI Push SDK has the service of automatic launch. To ensure that the application can normally receive the messages pushed by the app when it is closed or running it in the background process, the app will probably wake up the automatic launch or secondary launch service by status broadcasting of the system, which is necessary for application work. The application using the service is to ensure the stability of the push channels, which usually aims to push notifications to Android devices timely. In view of the fact that the MI Push SDK accesses the application in an integrated manner, the system will first wake up the service of MI Push SDK by broadcasting, and then the application will also start automatically. This behavior is necessary to ensure the notifications-pushing function works.

   4.2 To ensure that the application can normally receive the messages pushed by the app when it is closed or running it in the background process, the app will probably wake up the automatic launch or secondary launch service by status broadcasting of the system, which is necessary for application work.
