Android 12 able to start foreground activities in the background with ConnectivityManager-CodePudding

I have an Intent that was started using startForegroundService(intent)

What triggers it is

connectivityManager.registerDefaultNetworkCallback(object : NetworkCallback() {
      override fun onAvailable(network: Network) {
        startForegroundService(intent)
      }
    })

I thought Android12 doesn't let you start foreground services from the background, and this doesn't seem to fall in any exemption cases. How come the code ran without any issue?

CodePudding user response：

Are you sure that your app's targetSdk is >= 31? It sounds like it's probably targeting a lower level, and in that case, the background restrictions don't apply.

Here's the actual page from Google, and a direct quote:

Apps that target Android 12 or higher can't start foreground services while running in the background, except for a few special cases. If an app attempts to start a foreground service while running in the background, an exception occurs (except for the few special cases)
