Android IntentService Instantiation error

Question

Android RuntimeException: Unable to instantiate the service

I am downloading my data using IntentService. My IntentService class definition is as follows:

public class DownloadService extends IntentService{
super("DownloadService");
@Override
    protected void onHandleIntent(Intent intent) {
        //download tasks...
    }
}

AndroidManifest.xml:

<appilcation>
<service android:name="DownloadService"/>
..
..
..
</application>

LauncherActivity.java:

@Override
public void onCreate(Bundle savedInstanceState) {
        ..
        ..
        ..
    Intent dwnldService = new Intent(this, DownloadService.class);
    startService(dwnldService);
}

But still I am getting this error:

Answer 1

public DownloadService() {
    super("Download service");
}

Try adding this to your service.
