Question

I was working on a project and had my Activities passing each other information via Intents. However, I recently decided to swithc and go with the Singleton method and have an Application class holding all of my data.

I’m now a little confused: how do I start my Activities without Intents? This is a call I had before I switched…

    public boolean onOptionsItemSelected( MenuItem item ) {
    switch( item.getItemId() ) {
    case R.id.connect:
        startActivityForResult( new Intent( this, DeviceList.class ), REQUEST_CONNECT_DEVICE  );
        return true;

What would I change it to to start the DeviceList class without the use of intents?

Answer 1

You don’t. Use intents to start your activities. This is how Android is designed.
