why it would be my pleasure to help you good sir:

myTabHost.setOnTabChangedListener(new OnTabChangeListener(){
@Override
public void onTabChanged(String tabId) {
    if(TAB_1_TAG.equals(tabId)) {
        //destroy earth
    }
    if(TAB_2_TAG.equals(tabId)) {
        //destroy mars
    }
}});

Where TAB_1_TAG is the tag provided to the newTabSpec method when creating the tab.

Thanks for the help, and I LOL'd so hard on // destroy earth and // destroy mars – Naskov Mar 28 '13 at 12:50
@pgsandstrom first of all, thanks a milion! there is so little on TabHost methods online at all. this really saved me. my only confusion is why the method call is `setOnTabChangedListener`, but it instantiates as `OnTabChangeListener()`. there is no "d" in the instantiation! hmm ;) – Azurespot Apr 29 '14 at 06:55

I think in many cases it makes sense to make your TabActivity the listener:

public class MyTabActivity extends TabActivity implements OnTabChangeListener {

    private TabHost tabHost;

    @Override
    public void onCreate(Bundle savedInstanceState) {
        super.onCreate(savedInstanceState);
        /* Your onCreate code here */

        tabHost.setOnTabChangedListener(this);
    }

    /* ... */

    @Override
    public void onTabChanged(String tabId) {
        /* Your code to handle tab changes */
    }
}

You can use OnTabSelectedListener, here is an example.

  tabLayout.addOnTabSelectedListener(new TabLayout.OnTabSelectedListener() {
        @Override
        public void onTabSelected(TabLayout.Tab tab) {
            switch (tab.getText().toString()) {
                case "yourTabTitle":
                    //todo your code
                    break;
            }
        }
        @Override
        public void onTabUnselected(TabLayout.Tab tab) {
            switch (tab.getText().toString()) {
                case "yourTabTitle":
                    //todo your code
                    break;
            }
        }
        @Override
        public void onTabReselected(TabLayout.Tab tab) {
            switch (tab.getText().toString()) {
                case "yourTabTitle":
                    //todo your code
                    break;
            }
        }
    });
