Direct build from eclipse is different from the exported apk

Question

I saw another question here that is the same as mine, but no one answered it. I thought maybe I could try my luck.

I have an android application. The behavior I want is that, whenever the user visits a fragment/activity, and he closes my app/opens another app, when he returns to my app, he shall be presented with the screen that he last accessed.

This holds true whenever I run the app via Eclipse.

I noticed however, that when I export my APK, this doesnt happen. What happens is that no matter what fragment/activity the user last accessed, he always returns to the page after the splashcreen.

1. What could I be doing wrong?
2. What could be the reason behind this, direct build is not the same as the APK.

this is the code that happens when I resume

protected void onResume() {
    super.onResume();
    showPin();
    ((TextView) getSupportActionBar().getCustomView()).setText("MyTitle");
}

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

    if (currentFragment == null)
        currentFragment = builder;

    getSupportFragmentManager()
        .beginTransaction()
        .hide(builder)
        .hide(gem)
        .hide(tyke)
        .hide(spike)
        .hide(addon)
        .hide(recent)
        .hide(timber)
        .commit();


    getSupportFragmentManager()
        .beginTransaction()
        .show(currentFragment)
        .commit();

}
