Transfer Socket From One Activity To Another

I am trying to transfer Socket attribute from one Activity to another but i can not use Intent.putExtra() method. socket = new Socket('10.0.0.9', port); i = new Intent(getBaseConte

Solution 1:

You can't 'pass a Socket' from one Activity to another, but you do have other options.

Option 1. Create a class with a static reference to your Socket and access it that way. In your first Activity you set the Socket, which can then be accessed statically from your second Activity.

Eg.

publicclassSocketHandler {
    privatestatic Socket socket;

    publicstaticsynchronized Socket getSocket(){
        return socket;
    }

    publicstaticsynchronizedvoidsetSocket(Socket socket){
        SocketHandler.socket = socket;
    }
}

You can then access it by calling SocketHandler.setSocket(socket) or SocketHandler.getSocket() from anywhere throughout your app.

Option 2. Override the Application and have a global reference to the socket in there.

Eg.

publicclassMyApplicationextendsApplication {
    privateSocket socket;

    publicSocketgetSocket(){
        return socket;
    }

    publicvoidsetSocket(Socket socket){
        SocketHandler.socket = socket;
    }
}

This option will require you to point to your Application in the manifest file. In your manifest's application tag, you need to add:

android:name="your.package.name.MyApplication"

You can then access it by getting a reference to the Application in your Activity:

MyApplicationapp= (MyApplication)activity.getApplication();
Socketsocket= app.getSocket();
