  1. POApp crash on 4th screen rotation (second time in landscape) with differing portrait and landscape layouts

    text
    <p>I have an app that uses two drastically different layouts for portrait and landscape. The portrait mode is the main use case, where the user can control the application, and consists of a ListView with a few other views elements around it. The landscape layout is just an informational view of whatever was last selected in the portrait view, and consists of a ViewPager filled with WebViews, and some of the same views as in the protrait mode, but not all of them . When I run the app in debugging mode from Eclipse, and I rotate from portrait to landscape, back to portrait, and then back to landscape, it crashes on the last rotation to landscape every time (Stack printout in logcat below). If I run the app on my phone without debugging mode, it does not crash. The stack trace does not tell me much of why the crash happens. I try to make sure the views are not null where-ever they are used in the code.</p> <p>My problem looks similar to <a href="http://groups.google.com/group/android-developers/browse_thread/thread/c9159dc972a15870#" rel="nofollow">this</a>, but there's no further detail on a solution in that conversation either. Can anyone give me a clue on what could be going wrong? My guesses: The app runs out of memory (some kind of memory leak occurs with each rotation, and that causes the crash after 4 rotations). </p> <p>Or should I refactor my app and somehow make the two drastically different layouts two different activities? The two layouts share just enough functionality to make me want to use the same activity.</p> <p><strong>Logcat stack trace:</strong></p> <pre><code>10-16 21:53:58.690: ERROR/AndroidRuntime(4494): FATAL EXCEPTION: main 10-16 21:53:58.690: ERROR/AndroidRuntime(4494): java.lang.RuntimeException: Unable to start activity ComponentInfo{com.fonkmobile.player22tracks/com.fonkmobile.player22tracks.PlaylistActivity}: android.view.InflateException: Binary XML file line #2: Error inflating class &lt;unknown&gt;

    1. COI suspect a memory leak. How are you handling the configuration change in the activity? If you're using the default (let the system destroy and restart your activity), then there are lots of opportunities for memory leaks. Do you have any static variables in your activity class? Are you saving anything that might leak the old activity when the configuration changes? Perhaps post the code for those parts of your activity that deal with its life cycle.

    2. COI'm using the default, yes. No static variables, but lots of handlers registered on the views, and many of the views have background images that change during execution. The OnCreate is rather large, I'm not sure what part of it to post really? What should I watch out for to stop memory leaks, or is there another way to handle the rotation other than the default that will be safer regarding leaks?

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.
