    <p>I try to play with Service in Android, my application contain an Activity with a button so that it can do action when I press it. The core component is the ExtractingURLService , which extends IntentService framework class. I have overrided the onHandleIntent() method, so that it can handle intent passed to it properly. Code:</p> <pre><code>public class ExtractingURLService extends IntentService { private static final String TAG = "ExtractingURLService"; public ExtractingURLService(String name) { super("ExtractingURLService"); } @Override protected void onHandleIntent(Intent intent) { // do something here ! } } } </code></pre> <p>The Android Manifest file is :</p> <pre><code>&lt;manifest xmlns:android="http://schemas.android.com/apk/res/android" package="example.service.urlextraction" android:versionCode="1" android:versionName="1.0"&gt; &lt;uses-sdk android:minSdkVersion="10" /&gt; &lt;uses-permission android:name="android.permission.INTERNET"/&gt; &lt;application android:icon="@drawable/icon" android:label="@string/app_name"&gt; &lt;activity android:name=".ServiceExample02Activity" 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;service android:name=".ExtractingURLService" android:enabled="true"&gt;&lt;/service&gt; &lt;/application&gt; &lt;/manifest&gt; </code></pre> <p>In my only Activity class, I call the service by using:</p> <pre><code>Intent startServiceIntent = new Intent(this, ExtractingURLService.class); startService(startServiceIntent); </code></pre> <p>That's all my work, but when deploy, the runtime error I received was:</p> <blockquote> <p>04-09 16:24:05.751: ERROR/AndroidRuntime(1078): Caused by: java.lang.InstantiationException: example.service.urlextraction.ExtractingURLService</p> </blockquote> <p>What I should do with that ?? </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.
