Multiple MapActivity Elements on the Stack

I understand that this topic has been considered several times, and the often proposed solution to have "several" MapActivity classes is to run one in different processes. I do not want to do this, I have 3.

Instead, I redesigned one subclass of MapActivity to work in three different modes.


package com.rossgreenhalf.maptest.activity;

import android.os.Bundle;

import com.google.android.maps.MapActivity;

public class MyMapActivity extends MapActivity {

    @Override
    protected void onCreate(Bundle icicle) {
    super.onCreate(icicle);

    /* Inflate xml view, Set Zoom etc */
    }

    @Override
    protected void onResume() {
        super.onResume();

        int mode = getIntent().getExtras().getInt("MAP_MODE");

        switch(mode){
        case 1:
            /* Some markers to show */
            break;
        case 2:
            /* Just one Marker */
            break;
        case 3: 
            /* Only showing my location */
            break;
        }
    }

    @Override
    protected boolean isRouteDisplayed() {
    return false;
    }
}

I allow multiple instances of MapActivity to be inside the task stack, as its launch mode is still set to Standard. This approach seems to work fine, and I don't get the Shutdown Connection Pool Shutdown message, which seems to be coming out, I'm a little confused as to whether there are actually multiple instances of MapActivity or if android is automatically used?
