Running Custom Background Tasks with NativeScript
Running Custom Background Task
For Android sample project please see this repo - https://github.com/NativeScript/sample-android-background-services
A sample project demonstrating how NativeScript application can execute JavaScript code while the app is in background state. On applicationDidEnterBackground the app starts a custom background task. It uses the NSTimer API to print a console message on a fixed time interval. To start the task press the Home button in order to move the app to the background.
Since iOS doesn't allow a general-purpose background task to run forever, such a task will be suspended by the operating system after approximately 3 minutes. In some special cases your task is allowed to run longer, but you need to use UIBackgroundModes in your
Info.plistfile to specify the intent of your task (which automatically makes it not general-purpose).
Running the sample
