(Thus the service must maintain some sort of queue and be able to cancel it's ongoing requests for others of higher priority). I'd like the service to be relatively unobtrusive to the user such that they don't find it running after they are done with the application - if I want to do something

问题 I am writing an Android application that interfaces with a RESTful service. This web service essentially fronts a file system, and provides metadata as well CRUD access to the files. My application retrieves the metadata, and exposes it to 3rd party apps through a ContentProvider . I need to add the ability for 3rd party applications, running on the same device as my app, to CRUD the actual files by making requests to/from my app (not directly with the server). This means they need to either

问题 TL;DR How can I make a notification that does some work from the lock-screen without unlocking? After clicking an action, a button on the notification or just the complete notification, I want to do an API call (without typing my unlock code) Details Goal Based on the answer on this question I tried to make a notification with an action that works on the lockscreen without unlocking the device.

问题 I've inherited a code base for an Android app and I'm facing a particularly though problem with local notifications. The idea is to send a notification for each event which is scheduled in the future, considering also the reminder preference on how many minutes before the event the user wants to be notified.
