Fragment :opening activity from fragment giving ActivityNotFoundException:

Question

I am trying to open an activity from Listfragment as below

@Override
    public void onListItemClick(ListView l, View v, int position, long id) {
        super.onListItemClick(l, v, position, id);
        ((MenuActivity)getActivity()).getSlideoutHelper().close();
        Intent myIntent = new Intent(getActivity(), TravellerTimer.class);
        getActivity().startActivity(myIntent.addFlags(Intent.FLAG_ACTIVITY_NO_HISTORY));

    }

i registered the TimeTraveller activity in manifest file but still its giving ActivityNotFoundException

Any help is appreciated. thanks

Please read your logcat error carefully. It says have you declared this activity in your AndroidManifest.xml? did you do that? — jaga, Apr 19 '13 at 12:00
`have you declared this activity in your AndroidManifest.xml?` no need to ask — Pragnani, Apr 19 '13 at 12:00
You have written : "i registered the TimeTraveller activity in manifest file but still its giving ActivityNotFoundException". the logcat says com.example.activity.TravellerTimer is not Found. check the Spelling. — SKK, Apr 19 '13 at 12:09
@Santhosh now its gving classcastexception Caused by: java.lang.ClassCastException: android.app.Application cannot be cast to com.example.activity.TimerPrefrence 04-19 17:45:20.445: E/AndroidRuntime(15697): at com.example.activity.TravellerTimer.onCreate(TravellerTimer.java:48) 04-19 17:45:20.445: E/AndroidRuntime(15697): at android.app.Activity.performCreate(Activity.java:5206) 04-19 17:45:20.445: E/AndroidRuntime(15697): at — hari86, Apr 19 '13 at 12:16
@hari86: class cast exception means you are trying to assign a reference to some other type. for example you might be assigning editText id declared in XML to a textView. paste your TravellerTimer.onCreate() and XML layout file for the same. — SKK, Apr 19 '13 at 12:55

Make sure that you have registered the Activity with full correct package name in the manifest

Try the current class object using 'this' keyword to call your activity in the intent parameter .

Intent myIntent = new Intent(this.Urcurrentactivity, TravellerTimer.class);      this.Urcurrentactivity.startActivity(myIntent.addFlags(Intent.FLAG_ACTIVITY_NO_HISTORY));

Your code should also work but by just seeing this quotes, i cant make it sure .

By seeing your code in PasteBin:

ArrayList<ActiveTimer> timerLists = new ArrayList<ActiveTimer>();
timerLists = ((TimerPrefrence) getApplication()).viewTimer();

you are trying to cast TimerPrefrence to an ActiveTimer ArrayList. That is the reason you are getting Class cast exception.
