Alarm everyday at 5AM morning

由 送分小仙女□ 提交于 2019-12-06 16:24:24

But if there is any better solution for this, then please

问题 I have an Android application that has a service that runs in the background, communicates with a remote server and displays notifications to users if needed. The app also has an activity for users to interact with. One of the requirements is that the application needs to start itself automatically in the morning. At the end of the day the user is free to quit the app (Quit functionality stops the service, releases the wake lock, and lets Android kill the process). In order to automatically
