    <p>I know it sounds like a duplicate of <a href="https://stackoverflow.com/questions/11296411/fragmentstatepageradapter-illegalstateexception-myfragment-is-not-currently">FragmentStatePagerAdapter IllegalStateException: &lt;MyFragment&gt; is not currently in the FragmentManager</a> but his solution isn't relevant to my case.</p> <p>I'm getting the following crash very rarely:</p> <blockquote> <p>java.lang.RuntimeException: Unable to pause activity {MyActivity}: </p> <p>...</p> <p>Caused by: java.lang.IllegalStateException: Fragment MyFragment {40648258 id=0x7f070051} is not currently in the FragmentManager at android.support.v4.app.FragmentManagerImpl.putFragment(MT:516) at android.support.v4.app.FragmentStatePagerAdapter.saveState(MT:185) at android.support.v4.view.ViewPager.onSaveInstanceState(MT:881) </p> <p>...</p> <p>at android.view.View.saveHierarchyState(View.java:6238) at com.android.internal.policy.impl.PhoneWindow.saveHierarchyState(PhoneWindow.java:1522) at android.app.Activity.onSaveInstanceState(Activity.java:1138) at android.support.v4.app.FragmentActivity.onSaveInstanceState(MT:480) at MyActivity.onSaveInstanceState(MT:336)</p> </blockquote> <p>It seems like this is the weird code I can't understand from <code>FragmentStatePagerAdapter</code>:</p> <pre><code>for (int i=0; i&lt;mFragments.size(); i++) { Fragment f = mFragments.get(i); if (f != null) { if (state == null) { state = new Bundle(); } String key = "f" + i; mFragmentManager.putFragment(state, key, f); } } </code></pre> <p>It looks like the adapter gets my <code>Fragment</code> from <code>mFragments</code> but can't add its state to <code>FragmentManager</code>.</p> <p>I've couldn't find any way to recreate this on my test devices, only received this from some users.</p> <p>I'm using support package v4.</p> <p>Any help? Thanks.</p>

    2. COI had a similar error and the suggested link by Alejandro Colorado soved it. After a cursory look at the support library source it looks like that the Fragment state is "not active" (mIndex < 0). Due to the completely random nature of the bug (I have not been able to reproduce it), I would think that it's the expression of a problem deeply rooted in the Fragment/FragmentManager code...

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.

SQuiL has stopped working due to an internal error.

If you are curious you may find further information in the browser console, which is accessible through the devtools (F12).
