Description

On Android 11 and above, when the location permission is requested the user can allow the app to access the device location "Only this time". When this option is selected and the app is moved to the background, after a short time (around one minute) the one time session expires and the app is killed. This behavior also occurs when an in-app browser is launched from the main NativeScript activity, which is how I found this issue.

I tested on an Android 11 emulator. The manifest includes ACCESS_COARSE_LOCATION, ACCESS_FINE_LOCATION, ACCESS_BACKGROUND_LOCATION permissions.
These are the device logs:

To reproduce:

  1. Create a new NS8 project (I was unable to run the demo app)
  2. Install and configure the plugin
  3. Call enableLocationRequest
  4. Select "Only this time"
  5. Minimize the app

Is it a default Android behavior or is it possibile to fix this issue, for example extending the one-time session duration?

Research direction

Start with the enableLocationRequest entry point and reproduce the behavior on an Android 11 emulator using the listed steps and device logs. Determine whether the one-time permission revocation is default Android behavior or whether the plugin exposes a supported fix; done means establishing and documenting the result or implementing and verifying a fix.
