    <p>I am displaying my database in a <code>ListView</code>. I used a <code>Button</code> named <code>find geopoint</code> for displaying the database. when I click on it, the application crashes. Here is the stack trace:</p> <pre><code>08-25 17:03:11.308: ERROR/AndroidRuntime(8373): Uncaught handler: thread main exiting due to uncaught exception 08-25 17:03:11.338: ERROR/AndroidRuntime(8373): java.lang.RuntimeException: Unable to start activity ComponentInfo{com.cortes/com.cortes.Display}: java.lang.IllegalStateException: get field slot from row 1 col -1 failed 08-25 17:03:11.338: ERROR/AndroidRuntime(8373): at android.app.ActivityThread.performLaunchActivity(ActivityThread.java:2496) 08-25 17:03:11.338: ERROR/AndroidRuntime(8373): at android.app.ActivityThread.handleLaunchActivity(ActivityThread.java:2512) 08-25 17:03:11.338: ERROR/AndroidRuntime(8373): at android.app.ActivityThread.access$2200(ActivityThread.java:119) 08-25 17:03:11.338: ERROR/AndroidRuntime(8373): at android.app.ActivityThread$H.handleMessage(ActivityThread.java:1863) 08-25 17:03:11.338: ERROR/AndroidRuntime(8373): at android.os.Handler.dispatchMessage(Handler.java:99) 08-25 17:03:11.338: ERROR/AndroidRuntime(8373): at android.os.Looper.loop(Looper.java:123) 08-25 17:03:11.338: ERROR/AndroidRuntime(8373): at android.app.ActivityThread.main(ActivityThread.java:4363) 08-25 17:03:11.338: ERROR/AndroidRuntime(8373): at java.lang.reflect.Method.invokeNative(Native Method) 08-25 17:03:11.338: ERROR/AndroidRuntime(8373): at java.lang.reflect.Method.invoke(Method.java:521) 08-25 17:03:11.338: ERROR/AndroidRuntime(8373): at com.android.internal.os.ZygoteInit$MethodAndArgsCaller.run(ZygoteInit.java:862) 08-25 17:03:11.338: ERROR/AndroidRuntime(8373): at com.android.internal.os.ZygoteInit.main(ZygoteInit.java:620) 08-25 17:03:11.338: ERROR/AndroidRuntime(8373): at dalvik.system.NativeStart.main(Native Method) 08-25 17:03:11.338: ERROR/AndroidRuntime(8373): Caused by: java.lang.IllegalStateException: get field slot from row 1 col -1 failed 08-25 17:03:11.338: ERROR/AndroidRuntime(8373): at android.database.CursorWindow.getString_native(Native Method) 08-25 17:03:11.338: ERROR/AndroidRuntime(8373): at android.database.CursorWindow.getString(CursorWindow.java:363) 08-25 17:03:11.338: ERROR/AndroidRuntime(8373): at android.database.AbstractWindowedCursor.getString(AbstractWindowedCursor.java:49) 08-25 17:03:11.338: ERROR/AndroidRuntime(8373): at com.cortes.Display.onCreate(Display.java:116) 08-25 17:03:11.338: ERROR/AndroidRuntime(8373): at android.app.Instrumentation.callActivityOnCreate(Instrumentation.java:1047) 08-25 17:03:11.338: ERROR/AndroidRuntime(8373): at android.app.ActivityThread.performLaunchActivity(ActivityThread.java:2459) 08-25 17:03:11.338: ERROR/AndroidRuntime(8373): ... 11 more </code></pre> <p>Here is my code:</p> <pre><code>c = db.query(Geo_Create_Table, new String[ {"_id","latitude","longitude","address"}, null,null, null, null, null); x1 = c.getColumnIndex("_id"); y1 = c.getColumnIndex("latitude"); z1 = c.getColumnIndex("longiitude"); w1 = c.getColumnIndex("address"); while(c.moveToNext()) { a = c.getInt(x1); b1 = c.getString(y1); c1 = c.getString(z1); e = c.getString(w1); results.add(a+"" + " " + b1 + " " + c1 + " " + e); } ArrayAdapter&lt;String&gt; a11=new ArrayAdapter&lt;String&gt;(this, android.R.layout.simple_list_item_1, results); lv.setAdapter(a11); </code></pre> <p>Here is my <code>AndroidManifest.xml</code> file:</p> <pre><code>&lt;?xml version="1.0" encoding="utf-8"?&gt; &lt;manifest xmlns:android="http://schemas.android.com/apk/res/android" package="com.cortes" android:versionCode="1" android:versionName="1.0"&gt; &lt;uses-sdk android:minSdkVersion="7" /&gt; &lt;uses-permission android:name="android.permission.ACCESS_FINE_LOCATION" /&gt; &lt;uses-permission android:name="android.permission.ACCESS_COARSE_LOCATION" /&gt; &lt;uses-permission android:name="android.permission.ACCESS_LOCATION_EXTRA_COMMANDS" /&gt; &lt;uses-permission android:name="android.permission.ACCESS_MOCK_LOCATION" /&gt; &lt;uses-permission android:name="android.permission.ACCESS_NETWORK_STATE" /&gt; &lt;uses-permission android:name="android.permission.ACCESS_WIFI_STATE" /&gt; &lt;uses-permission android:name="android.permission.INTERNET" /&gt; &lt;application android:icon="@drawable/icon" android:label="@string/app_name"&gt; &lt;uses-library android:required="true" android:name="com.google.android.maps"/&gt; &lt;activity android:name=".Cortes" android:label="@string/app_name"&gt; &lt;intent-filter&gt; &lt;action android:name="android.intent.action.MAIN" /&gt; &lt;category android:name="android.intent.category.LAUNCHER" /&gt; &lt;/intent-filter&gt; &lt;/activity&gt; &lt;activity android:name=".Display" android:label="@string/app_name" android:launchMode="singleTask"&gt; &lt;intent-filter&gt; &lt;action android:name="android.intent.action.VIEW" /&gt; &lt;category android:name="android.intent.category.DEFAULT" /&gt; &lt;/intent-filter&gt; &lt;/activity&gt; &lt;/application&gt; &lt;/manifest&gt; </code></pre> <p>Any suggestions on how to solve this problem?</p>

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).
