    <p>My app crashes when I try to launch a new activity. The stack trace does not show anything from my code. I have tested it in both the 1.6 emulator and the 2.1 emulator and it crashes in both situations however it runs on a 2.2 device. Does anyone know what could make the emulator crash like this?</p> <p><strong>Stacktrace</strong></p> <pre><code>01-13 16:18:33.232: E/AndroidRuntime(284): Uncaught handler: thread main exiting due to uncaught exception 01-13 16:18:33.232: E/AndroidRuntime(284): java.lang.NullPointerException 01-13 16:18:33.232: E/AndroidRuntime(284): at android.widget.TabHost.dispatchWindowFocusChanged(TabHost.java:292) 01-13 16:18:33.232: E/AndroidRuntime(284): at android.view.ViewGroup.dispatchWindowFocusChanged(ViewGroup.java:659) 01-13 16:18:33.232: E/AndroidRuntime(284): at android.view.ViewGroup.dispatchWindowFocusChanged(ViewGroup.java:659) 01-13 16:18:33.232: E/AndroidRuntime(284): at android.view.ViewGroup.dispatchWindowFocusChanged(ViewGroup.java:659) 01-13 16:18:33.232: E/AndroidRuntime(284): at android.view.ViewRoot.handleMessage(ViewRoot.java:1782) 01-13 16:18:33.232: E/AndroidRuntime(284): at android.os.Handler.dispatchMessage(Handler.java:99) 01-13 16:18:33.232: E/AndroidRuntime(284): at android.os.Looper.loop(Looper.java:123) 01-13 16:18:33.232: E/AndroidRuntime(284): at android.app.ActivityThread.main(ActivityThread.java:4203) 01-13 16:18:33.232: E/AndroidRuntime(284): at java.lang.reflect.Method.invokeNative(Native Method) 01-13 16:18:33.232: E/AndroidRuntime(284): at java.lang.reflect.Method.invoke(Method.java:521) 01-13 16:18:33.232: E/AndroidRuntime(284): at com.android.internal.os.ZygoteInit$MethodAndArgsCaller.run(ZygoteInit.java:791) 01-13 16:18:33.232: E/AndroidRuntime(284): at com.android.internal.os.ZygoteInit.main(ZygoteInit.java:549) 01-13 16:18:33.232: E/AndroidRuntime(284): at dalvik.system.NativeStart.main(Native Method) 01-13 16:18:33.242: I/dalvikvm(284): threadid=7: reacting to signal 3 01-13 16:18:33.422: I/dalvikvm(284): Wrote stack trace to '/data/anr/traces.txt' </code></pre>

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).
