(also this stackoverflow.com/questions/4195089 don't have answer).</p> <p>In my test app on emulator i have error <strong>ERROR/Cursor(1512): Invalid statement in fillWindow()</strong> on LogCat when i press back button on second activity.<br /> <sub><i>11-23 19:06:05.050: DEBUG/TestDB/Debug/MainActivity(1512): onCreate<br /> 11-23 19:06:06.820: DEBUG/TestDB/Debug/MainActivity(1512): openDataBase<br /> 11-23 19:06:07.240: DEBUG/TestDB/Debug/MainActivity(1512): String[] from<br /> 11-23 19:06:07.270: DEBUG/TestDB/Debug/MainActivity(1512): SimpleCursorAdapter<br /> 11-23 19:06:07.500: DEBUG/TestDB/Debug/MainActivity(1512): myDbHelper.close<br /> 11-23 19:06:07.520: DEBUG/TestDB/Debug/MainActivity(1512): onStart<br /> 11-23 19:06:07.551: DEBUG/TestDB/Debug/MainActivity(1512): onResume<br /> 11-23 19:06:09.040: INFO/ActivityManager(587): Displayed activity ru.olegi/.MainActivity: 7962 ms<br /> 11-23 19:06:11.850: INFO/ActivityManager(587): Starting activity: Intent { comp={ru.olegi/ru.olegi.AnotherActivity} }<br /> 11-23 19:06:12.100: DEBUG/TestDB/Debug/AnotherActivity(1512): onCreate<br /> 11-23 19:06:12.970: INFO/ActivityManager(587): Displayed activity ru.olegi/.AnotherActivity: 1100 ms<br /> 11-23 19:06:14.550: ERROR/Cursor(1512): Invalid statement in fillWindow()<br /> 11-23 19:06:14.590: DEBUG/TestDB/Debug/MainActivity(1512): onStart<br /> 11-23 19:06:14.600: DEBUG/TestDB/Debug/MainActivity(1512): onResume<br /> </i></sub><br/></p> <p>All code stored in onCreate.

Longer answer; By declaring db in the method you're saying to the JVM that when the method finishes your database connection (db) is no longer useful. What you should do is declare db at the class level instead of the method level, create it in onCreate, and close it in onDestroy.</p> </blockquote> <p>Ok, i move sections // DATABASE OPEN - START and // DATABASE CLOSE - START to onCreate and to onDestory.

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).
