How to pass a Bluetooth Socket to another Activity using Application interface

so from what i gather, Socket connections are neither serializable or parcelable, but i need to pass a bluetooth connection to another Activity. i do not want to write a Service as a middle man, so please don't post this as a solution. i've heard that there is a way to pass these types of Objects using a custom Application interface, but i cannot, for the life of me, find a working example of this. i've seen plenty of documentation that says something to the effect of "this is possible" but nothing showing how to do it.

Solution

  • Define your app class:

    class MyApplication extends Application{
    // your fields here
}

    Add name attribute to app manifest. 

    <application android:name=".MyApplication" ../>

    Use it in Activity:

    MyApplication myapp = (MyApplication) getApplication();
