    <p>I'm working on an android appwidget and it works fine in all android versions I tried (emulator 1.5, 1.6, 2.3), but not 2.1 (physical device, LG GT540 upgraded to 2.1). I tested it on a Samsung GT I5801 fresh out of the box with the 2.1 OS and it worked, probably because tat particular revision the 2.1 version is older (or else Samsung themselves added the fix).</p> <p>By the way, this I think is the fix to the exact bug I am referring to:<br> <a href="https://android.googlesource.com/platform/packages/apps/Settings/+/7be5137e12ba58cebae634f640379599acdb491a" rel="nofollow noreferrer">https://android.googlesource.com/platform/packages/apps/Settings/+/7be5137e12ba58cebae634f640379599acdb491a</a></p> <p>And this is an older thread discussing the same problem: <a href="https://stackoverflow.com/questions/1573966/androidnpe-while-trying-to-activityforresult-with-action-appwidget-pick-intent">Android:NPE while trying to activityForResult with ACTION_APPWIDGET_PICK intent</a></p> <p>When I try to load the widget on the homescreen (actually it happens when I click the "Widgets" button) I get the following error:</p> <blockquote> <p>The application Settings (process com.android.settings) has stopped unexpectedly. Please try again.</p> </blockquote> <p>With a "Force close" button.</p> <p>See logcat output below. By the way this does not happen when my appwidget is not installed yet and it happens also on a 2.1 emulator.</p> <p>I have searched everywhere and there are lots of people mentioning this. Developers, but mostly users, and the general conclusion is that it is a bug in the android 2.1 OS. For example even google's own maps appwidget causes this crash.</p> <p>Now I know that there are appwidgets that work fine on 2.1. So there must be a work around. I just don't know what. I have read suggestions on here (sorry I can't find the link right now) that the appwidget needs more than one widget to get it to work. Mine now actually has 2 textviews, but I also tried with one textview and an image button. Neither works.</p> <p>I could of course avoid 2.1, but I rather would like this appwidget to work on as many android versions as possible (and I can't upgrade my GT540 as of yet), besides I am not willing to accept defeat. :-)</p> <p>Logcat stacktrace:</p> <pre><code>I/ActivityManager( 58): Starting activity: Intent { act=android.appwidget.action.APPWIDGET_PICK cmp=com.android.settings/.AppWidgetPickActivity (has extras) } W/InputManagerService( 58): Window already focused, ignoring focus gain of: com.android.internal.view.IInputMethodClient$Stub$Proxy@44d5d458 D/AndroidRuntime( 229): Shutting down VM W/dalvikvm( 229): threadid=3: thread exiting with uncaught exception (group=0x4001b188) E/AndroidRuntime( 229): Uncaught handler: thread main exiting due to uncaught exception E/AndroidRuntime( 229): java.lang.RuntimeException: Unable to start activity ComponentInfo{com.android.settings/com.android.settings.AppWidgetPickActivity}: java.lang.NullPointerException E/AndroidRuntime( 229): at android.app.ActivityThread.performLaunchActivity(ActivityThread.java:2496) E/AndroidRuntime( 229): at android.app.ActivityThread.handleLaunchActivity(ActivityThread.java:2512) E/AndroidRuntime( 229): at android.app.ActivityThread.access$2200(ActivityThread.java:119) E/AndroidRuntime( 229): at android.app.ActivityThread$H.handleMessage(ActivityThread.java:1863) E/AndroidRuntime( 229): at android.os.Handler.dispatchMessage(Handler.java:99) E/AndroidRuntime( 229): at android.os.Looper.loop(Looper.java:123) E/AndroidRuntime( 229): at android.app.ActivityThread.main(ActivityThread.java:4363) E/AndroidRuntime( 229): at java.lang.reflect.Method.invokeNative(Native Method) E/AndroidRuntime( 229): at java.lang.reflect.Method.invoke(Method.java:521) E/AndroidRuntime( 229): at com.android.internal.os.ZygoteInit$MethodAndArgsCaller.run(ZygoteInit.java:860) E/AndroidRuntime( 229): at com.android.internal.os.ZygoteInit.main(ZygoteInit.java:618) E/AndroidRuntime( 229): at dalvik.system.NativeStart.main(Native Method) E/AndroidRuntime( 229): Caused by: java.lang.NullPointerException E/AndroidRuntime( 229): at com.android.settings.ActivityPicker$IconResizer.createIconThumbnail(ActivityPicker.java:364) E/AndroidRuntime( 229): at com.android.settings.ActivityPicker$PickAdapter$Item.&lt;init&gt;(ActivityPicker.java:226) E/AndroidRuntime( 229): at com.android.settings.AppWidgetPickActivity.putAppWidgetItems(AppWidgetPickActivity.java:185) E/AndroidRuntime( 229): at com.android.settings.AppWidgetPickActivity.putInstalledAppWidgets(AppWidgetPickActivity.java:226) E/AndroidRuntime( 229): at com.android.settings.AppWidgetPickActivity.getItems(AppWidgetPickActivity.java:207) E/AndroidRuntime( 229): at com.android.settings.ActivityPicker.onCreate(ActivityPicker.java:98) E/AndroidRuntime( 229): at com.android.settings.AppWidgetPickActivity.onCreate(AppWidgetPickActivity.java:63) E/AndroidRuntime( 229): at android.app.Instrumentation.callActivityOnCreate(Instrumentation.java:1047) E/AndroidRuntime( 229): at android.app.ActivityThread.performLaunchActivity(ActivityThread.java:2459) E/AndroidRuntime( 229): ... 11 more I/Process ( 58): Sending signal.

    1. CO@aseg, although your logcat is not "handy," it is needed to answer your question. You also say that other sites have mentioned this error. Do you have links?

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.
