How to Detect network disconnection in Firebase Job dispatcher?

Question

In firebase Job dispatcher its possible to detect when we connect to a network, but how to detect when we disconnect from a network?

    Job myJob = dispatcher.newJobBuilder()
    .setService(MyJobService.class) 
    .setTag("my-unique-tag")
    .setConstraints(
    // only run on an unmetered network
    Constraint.ON_UNMETERED_NETWORK,
    // only run when the device is charging
    Constraint.DEVICE_CHARGING
     )
    .build();

dispatcher.mustSchedule(myJob);

This will detect when connected to Unmetrered Network , i want to start a service whenever it is disconnected from all networks

Answer 1

Using firebase dispatcher you can't check the disconnection (As far as I know), but you can use broadcast receivers for detecting connectivity change and call your job service inside them

refer this link for the usage of broadcast receivers

Broadcast receiver for checking internet connection in android app

in latest versions of android you need to dynamically register and unregister the Broadcast Receivers
