    <p>Update below:</p> <p>I have this maps activity started when I click a button. I receive the below in the logcat. I have the activity added to the manifest. I have the setContentView inside the onCreate. I also have the permissions declared in the manifest. The layout xml is just a map fragment. Anyone see anything that might be the cause of this problem?</p> <p>logcat:</p> <pre><code>10-09 23:16:10.516: W/dalvikvm(27281): threadid=1: thread exiting with uncaught exception (group=0x41955700) 10-09 23:16:10.516: E/AndroidRuntime(27281): FATAL EXCEPTION: main 10-09 23:16:10.516: E/AndroidRuntime(27281): java.lang.RuntimeException: Unable to instantiate activity ComponentInfo{com.indeeditis/com.indeeditis.FinderActivity}: java.lang.NullPointerException 10-09 23:16:10.516: E/AndroidRuntime(27281): at android.app.ActivityThread.performLaunchActivity(ActivityThread.java:2137) 10-09 23:16:10.516: E/AndroidRuntime(27281): at android.app.ActivityThread.handleLaunchActivity(ActivityThread.java:2261) 10-09 23:16:10.516: E/AndroidRuntime(27281): at android.app.ActivityThread.access$600(ActivityThread.java:141) 10-09 23:16:10.516: E/AndroidRuntime(27281): at android.app.ActivityThread$H.handleMessage(ActivityThread.java:1256) 10-09 23:16:10.516: E/AndroidRuntime(27281): at android.os.Handler.dispatchMessage(Handler.java:99) 10-09 23:16:10.516: E/AndroidRuntime(27281): at android.os.Looper.loop(Looper.java:137) 10-09 23:16:10.516: E/AndroidRuntime(27281): at android.app.ActivityThread.main(ActivityThread.java:5103) 10-09 23:16:10.516: E/AndroidRuntime(27281): at java.lang.reflect.Method.invokeNative(Native Method) 10-09 23:16:10.516: E/AndroidRuntime(27281): at java.lang.reflect.Method.invoke(Method.java:525) 10-09 23:16:10.516: E/AndroidRuntime(27281): at com.android.internal.os.ZygoteInit$MethodAndArgsCaller.run(ZygoteInit.java:737) 10-09 23:16:10.516: E/AndroidRuntime(27281): at com.android.internal.os.ZygoteInit.main(ZygoteInit.java:553) 10-09 23:16:10.516: E/AndroidRuntime(27281): at dalvik.system.NativeStart.main(Native Method) 10-09 23:16:10.516: E/AndroidRuntime(27281): Caused by: java.lang.NullPointerException 10-09 23:16:10.516: E/AndroidRuntime(27281): at android.content.ContextWrapper.getPackageName(ContextWrapper.java:135) 10-09 23:16:10.516: E/AndroidRuntime(27281): at android.location.GeocoderParams.&lt;init&gt;(GeocoderParams.java:50) 10-09 23:16:10.516: E/AndroidRuntime(27281): at android.location.Geocoder.&lt;init&gt;(Geocoder.java:83) 10-09 23:16:10.516: E/AndroidRuntime(27281): at android.location.Geocoder.&lt;init&gt;(Geocoder.java:95) 10-09 23:16:10.516: E/AndroidRuntime(27281): at com.indeeditis.FinderActivity.&lt;init&gt;(FinderActivity.java:63) 10-09 23:16:10.516: E/AndroidRuntime(27281): at java.lang.Class.newInstanceImpl(Native Method) 10-09 23:16:10.516: E/AndroidRuntime(27281): at java.lang.Class.newInstance(Class.java:1130) 10-09 23:16:10.516: E/AndroidRuntime(27281): at android.app.Instrumentation.newActivity(Instrumentation.java:1061) 10-09 23:16:10.516: E/AndroidRuntime(27281): at android.app.ActivityThread.performLaunchActivity(ActivityThread.java:2128) 10-09 23:16:10.516: E/AndroidRuntime(27281): ... 11 more </code></pre> <p>Activity:</p> <pre><code>public class FinderActivity extends Activity implements LocationListener { GoogleMap mMap;

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.

If you are curious you may find further information in the browser console, which is accessible through the devtools (F12).
