    <p>I have an SQLiteDatabase helper, which returns a cursor with just the name column from a database:</p> <pre><code>public Cursor getNames() { Cursor cursor = db.query(TABLE_NAME, new String[] {NAME}, null, null, null, null, null); return cursor; } </code></pre> <p>I am trying to bind this cursor to a simple ListView contained in the Layout:</p> <pre><code>&lt;ListView android:id="@android:id/list" android:layout_width="match_parent" android:layout_height="wrap_content" &gt; &lt;/ListView&gt; </code></pre> <p>The java:</p> <pre><code> Cursor cursor = db.getNames(); startManagingCursor(cursor); ListAdapter adapter = new SimpleCursorAdapter ( this, android.R.layout.simple_list_item_1, cursor, new String[] {constants.NAME}, new int[] {android.R.id.text1} ); setListAdapter(adapter); </code></pre> <p>I've followed every tutorial I can find but the app still stops unexpectedly. Please tell me what I'm doing wrong! </p> <p>Here's the LOGCAT trace, hope thats what you needed:</p> <pre><code>12-03 17:18:41.557: E/AndroidRuntime(30413): FATAL EXCEPTION: main 12-03 17:18:41.557: E/AndroidRuntime(30413): java.lang.RuntimeException: Unable to start activity ComponentInfo{george.frost.YourCarbDatabase/com.android.CarbCount.Search}: java.lang.IllegalArgumentException: column '_id' does not exist 12-03 17:18:41.557: E/AndroidRuntime(30413): at android.app.ActivityThread.performLaunchActivity(ActivityThread.java:1659) 12-03 17:18:41.557: E/AndroidRuntime(30413): at android.app.ActivityThread.handleLaunchActivity(ActivityThread.java:1675) 12-03 17:18:41.557: E/AndroidRuntime(30413): at android.app.ActivityThread.access$1500(ActivityThread.java:121) 12-03 17:18:41.557: E/AndroidRuntime(30413): at android.app.ActivityThread$H.handleMessage(ActivityThread.java:943) 12-03 17:18:41.557: E/AndroidRuntime(30413): at android.os.Handler.dispatchMessage(Handler.java:99) 12-03 17:18:41.557: E/AndroidRuntime(30413): at android.os.Looper.loop(Looper.java:130) 12-03 17:18:41.557: E/AndroidRuntime(30413): at android.app.ActivityThread.main(ActivityThread.java:3701) 12-03 17:18:41.557: E/AndroidRuntime(30413): at java.lang.reflect.Method.invokeNative(Native Method) 12-03 17:18:41.557: E/AndroidRuntime(30413): at java.lang.reflect.Method.invoke(Method.java:507) 12-03 17:18:41.557: E/AndroidRuntime(30413): at com.android.internal.os.ZygoteInit$MethodAndArgsCaller.run(ZygoteInit.java:866) 12-03 17:18:41.557: E/AndroidRuntime(30413): at com.android.internal.os.ZygoteInit.main(ZygoteInit.java:624) 12-03 17:18:41.557: E/AndroidRuntime(30413): at dalvik.system.NativeStart.main(Native Method) 12-03 17:18:41.557: E/AndroidRuntime(30413): Caused by: java.lang.IllegalArgumentException: column '_id' does not exist 12-03 17:18:41.557: E/AndroidRuntime(30413): at android.database.AbstractCursor.getColumnIndexOrThrow(AbstractCursor.java:314) 12-03 17:18:41.557: E/AndroidRuntime(30413): at android.widget.CursorAdapter.init(CursorAdapter.java:111) 12-03 17:18:41.557: E/AndroidRuntime(30413): at android.widget.CursorAdapter.&lt;init&gt;(CursorAdapter.java:90) 12-03 17:18:41.557: E/AndroidRuntime(30413): at android.widget.ResourceCursorAdapter.&lt;init&gt;(ResourceCursorAdapter.java:47) 12-03 17:18:41.557: E/AndroidRuntime(30413): at android.widget.SimpleCursorAdapter.&lt;init&gt;(SimpleCursorAdapter.java:84) 12-03 17:18:41.557: E/AndroidRuntime(30413): at com.android.CarbCount.Search.onCreate(Search.java:42) 12-03 17:18:41.557: E/AndroidRuntime(30413): at android.app.Instrumentation.callActivityOnCreate(Instrumentation.java:1047) 12-03 17:18:41.557: E/AndroidRuntime(30413): at android.app.ActivityThread.performLaunchActivity(ActivityThread.java:1623) 12-03 17:18:41.557: E/AndroidRuntime(30413): ... 11 more </code></pre>

Guidance
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).
