Handler instances using deprecated constructors

[joeygrover]

Bug Report

As of Android SDK 30 the no parameter and callback constructors of the Handler class were deprecated. Now a Looper instance is required to be passed. The library uses the default,no param constructor in most cases.

See here: https://developer.android.com/reference/android/os/Handler#Handler()

Expected Behavior

The library does not use deprecated methods from the Android API.

Observed Behavior

The library uses deprecated constroctures for Handler instances

OS & Version Information

• Android Version: SDK 30
• SDL Android Version: 5.1.1

Test Case, Sample Code, and / or Example App

Two solutions are possible:

Update handler constructors

Handler handler = new Handler();

Needs to be replaced with

Handler handler = new Handler(Looper.getMainLooper());

Switch to using TaskMaster

Replace Handler with a queue from task master and create tasks to be used. This solution will not work in the cases where a Handler is passed to a Messenger instance, for example the binding between TransportBroker and SdlRouterService .
