    <p>I was able to do this by caching the Fragments as I added them in my own ArrayList. Then I set up an OnBackStackChangedListener to keep track of which one was shown and pop off the ArrayList as necessary.</p> <p>My purpose was a little different but the code below should be what you need for what you describe. The tags are so you can have multiple back stacks if you need. It won't compile as-is (I've clipped lots of my own code) but should give you an idea of how I did it. Additional disclaimer: I <strong>just</strong> got this working and there may be issues I haven't hit yet.</p> <pre><code> public void replaceFragmentWithBackStackForTag(Fragment fragment, String tag) { FragmentTransaction ft = getSupportFragmentManager().beginTransaction(); ft.detach(visibleFragment); ft.add(R.id.realtabcontent, fragment, tag); ft.attach(fragment); ft.addToBackStack(null); manualBackStacks.get(tag).add(fragment); ft.commit(); this.getSupportFragmentManager().executePendingTransactions(); } </code></pre> <p>The code you'll want where your activity gets recreated after an orientation change:</p> <pre><code> ArrayList&lt;Fragment&gt; backStack = new ArrayList&lt;Fragment&gt;(manualBackStacks.get(tag)); popArrayListToIndex(manualBackStacks.get(tag), 0); // helper I wrote for (int bs = 1; bs &lt; backStack.size(); bs++) { replaceFragmentWithBackStackForTag(backStack.get(bs), tag); } </code></pre> <p>The backstack listener:</p> <pre><code> public void onBackStackChanged() { int index = getSupportFragmentManager().getBackStackEntryCount(); ArrayList&lt;Fragment&gt; backStack = manualBackStacks.get(tag); visibleFragment = backStack.get(index); // Pop the last element if we've backed up. popArrayListToIndex(backStack, index); } </code></pre> <p>Hope this helps.</p>

    1. COI'm very interested in this approach, but I don't feel that your answer gives enough detail for me to easily understand. can you add more detail to your answer?

A row detail

Detail views are divided into sections. All the information in the data section comes from columns in the selected row. The other sections display data from other, related rows.

Related data can be related in a to-one or a to-many fashion. Captions of data related in a to-many fashion link to a list view showing a filtered view of the table.

Try moving around until you find a non-empty to-many entry and click on the label to get to one. You can move back to the root by clicking on the database name in the header.
