Android Services

Starting with Qt 5.7, you can create Android services using Qt. A service is a component that runs in background, so, it has no user interface. It is useful to perform long-term operations such as logging GPS, waiting for social media notifications, and so on. A service will continue to run even if the application that started it exits.

To create a service, do the following steps:

  1. Uncomment the service part of your AndroidManifest.xml.
  2. Make sure the service tag contains an android:process=":some_name" attribute. It is needed to force the service to run in a separate process than the activity.
  3. If you're using the same application (.so file) for activity and also for service, you need to use meta-data to pass some arguments to your main function in order to know which one is which.
  4. To enable background running, uncomment meta-data and set it to true (android:value="true" ).

Qt loads the .so file defined in meta-data, and calls the main function with all the arguments set in meta-data.
