Calling startActivity(intentServiceIntent) within (Sherlock)DialogFragment results in ActivityNotFoundException

Question

Scenario:

SherlockFragmentActivity displaying SherlockFragment. SherlockFragment showing SherlockDialogFragment.

Verions:

• Build API: Google APIs 15
• Compatibility/Support Package: v4
• ActionBarSherclock: 4.1.0
• Android Emulator: API-8

Code:

SherlockFragmentActivity:

public class TrailerDetailSherlockFragmentActivity extends SherlockFragmentActivity {
    ...
    /*
     * set up the fragment which will display the sensor details,
     * and allow changes of the alarm settings
     */                     
    detailFragment = new TempsensorDetailSherlockFragment();

    transaction = getSupportFragmentManager().beginTransaction();
    transaction.replace(R.id.framelayout_td_sensordetail, detailFragment);
    transaction.commit();   
    ...
    }

SherlockFragment:

public class TempsensorDetailSherlockFragment extends SherlockFragment {
    ...
    @Override
    public View onCreateView(LayoutInflater inflater, ViewGroup container, Bundle savedInstanceState) {
        ...
        // set the onClick method for the alarm values
        View alarmValueLayout = tempsensorDetailView.findViewById(R.id.ll_sd_minmax);
        alarmValueLayout.setOnClickListener(new OnClickListener() {

            @Override
            public void onClick(View v) {

                FragmentManager fm = activity.getSupportFragmentManager();

                // Create and show the dialog.
                SetAlarmTemperatureSherlockDialogFragment setAlarmTempsDialogFragment = new SetAlarmTemperatureSherlockDialogFragment(deviceString, alarm);
                setAlarmTempsDialogFragment.show(fm, "dialog");
            }
        });
        ...
    }

SherlockDialogFragment:

public class SetAlarmTemperatureSherlockDialogFragment extends SherlockDialogFragment {
    ...
    @Override
    public void onAttach(Activity activity) {
        ...
        this.activity = (SherlockFragmentActivity) activity;
        notificationServiceUtil = new NotificationServiceUtil(activity);
        ...
    }

    @Override
    public View onCreateView(LayoutInflater inflater, ViewGroup container,  Bundle savedInstanceState) {
    ...
    saveButton = (ImageButton) view.findViewById(R.id.btn_setalarmtemp_save);
            saveButton.setOnClickListener(new OnClickListener() {

                @Override
                public void onClick(View v) {

                    ...
                    notificationServiceUtil.alarmSubscribe(deviceString, bundle, new AlarmSubscribeHandler());
                }
            });
    ...
    }

For background jobs and data management, i'm using an IntentService. Therefore, i have created a helper class named NotificationServiceUtil:

public class NotificationServiceUtil {
    ...
    public NotificationServiceUtil(Activity activity) {
        this.activity = activity;
    }

    private void _initRestApiServiceIntent (String action) {
        restApiServiceIntent = new Intent(activity, NotificationService.class);
        restApiServiceIntent.setAction(action);
    }

    public void alarmSubscribe(String deviceString, Bundle bundle, Handler handler) {
        _initRestApiServiceIntent(NotificationService.ACTION_ALARM_SET);
        restApiServiceIntent.putExtras(bundle);
        restApiServiceIntent.putExtra(NotificationService.EXTRAKEY_DEVICE_STRING, deviceString);
        restApiServiceIntent.putExtra(NotificationService.EXTRAKEY_MESSENGER, new Messenger(handler));

        activity.startActivity(restApiServiceIntent);
    }
    ...
}

Part of the manifest:

    <activity 
        android:name=".activitys.MainSherlockFragmentActivity" 
        android:label="@string/app_name">
        <intent-filter>
            <action android:name="android.intent.action.MAIN" />
            <category android:name="android.intent.category.LAUNCHER" />
        </intent-filter>
   </activity>

   <activity
       android:name=".activitys.TrailerDetailSherlockFragmentActivity"
       android:label="@string/app_name"/>

   <service android:name=".services.NotificationService" />

EXCEPTION:

And this is the exception i'm getting, when clicking the save-button in the SetAlarmTemperatureSherlockDialogFragment:

Thoughts:

What you can see in the exception is, that startActivityForResult() is called, instead of startActivity(). I think this COULD be a bug in the support.v4 package, but i'm not sure at all.

But what i can say is, that the NotificationServiceUtil class works fine from e.g. Activity and SherlockFragmentActivity.

Does anyone have an idea how to fix this?

Answer 1

You're starting a Service, not an Activity. Change activity.startActivity() to activity.startService()

Answer 2

Just check the change, I have made to ur code, and don't forget to import

import android.app.NotificationManager;    //    in ur activity

public class NotificationServiceUtil {
    ...
    public NotificationServiceUtil(Activity activity) {
        this.activity = activity;
    }

    private void _initRestApiServiceIntent (String action) {
        NotificationManager nm = (NotificationManager) getSystemService(activity.NOTIFICATION_SERVICE);  <------ CHANGE
        restApiServiceIntent = new Intent(activity, nm.getClass());  <--- CHANGE
        restApiServiceIntent.setAction(action);
    }
    public void alarmSubscribe(String deviceString, Bundle bundle, Handler handler) {
        _initRestApiServiceIntent(NotificationService.ACTION_ALARM_SET);
        restApiServiceIntent.putExtras(bundle);
        restApiServiceIntent.putExtra(NotificationService.EXTRAKEY_DEVICE_STRING,     deviceString);
        restApiServiceIntent.putExtra(NotificationService.EXTRAKEY_MESSENGER, new Messenger(handler));

    activity.startActivity(restApiServiceIntent);
}
...
}
