Activity won't start even though it's declared in manifest file

Question

I have an activity which wont start.

The error receive is:

android.content.ActivityNotFoundException: Unable to find explicit activity class {com.example.its_time/com.example.its_time.actiongenre.ActioncomedyActivity}; have you declared this activity in your AndroidManifest.xml?

I have checked, and the activity is declared in the manifest file.

Why do I still get this error eventhough its declared ?

@Override
    protected void onCreate(Bundle savedInstanceState) {
        super.onCreate(savedInstanceState);
        setContentView(R.layout.nextactivity);

        pupulateListView();
        registerClickCallback();
    }

    private void registerClickCallback() {
ListView list = (ListView)findViewById(R.id.listViewGenres);

        list.setOnItemClickListener(new AdapterView.OnItemClickListener() {

            @Override
            public void onItemClick(AdapterView parent, View view,
                    int position, long id) {

                Intent intent;
                switch(position)
                {
                case 0:
                    intent = new Intent(NextactivityActivity.this,ActiongenreActivity.class);
                    startActivity(intent);
                    break;
                case 1:
                    intent = new Intent(NextactivityActivity.this,AnimationActivity.class);
                    startActivity(intent);
                    break;
                case 2:
                    intent = new Intent(NextactivityActivity.this,ComedyActivity.class);
                    startActivity(intent);
                    break;
                case 3:
                    intent = new Intent(NextactivityActivity.this,DokumentaryActivity.class);
                    startActivity(intent);
                    break;
                case 4:
                    intent = new Intent(NextactivityActivity.this,HorrorActivity.class);
                    startActivity(intent);
                    break;
                case 5:
                    intent = new Intent(NextactivityActivity.this,ScifiActivity.class);
                    startActivity(intent);
                    break;
                case 6:
                    intent = new Intent(NextactivityActivity.this,Drama2Activity.class);
                    startActivity(intent);
                    break;
                default:
                    break;
                }

            }
        });

    }

    private void pupulateListView() {
        String[] myItems = {"Action","Animation","Komedi","Dokumentär","Skräck","Sci-fi","Drama"};

        ArrayAdapter adapter = new ArrayAdapter(this,R.layout.the_list_genres,myItems);
        ListView list = (ListView)findViewById(R.id.listViewGenres);
        list.setAdapter(adapter);

    }


    }

This is the first piece of code that takes me to the next step, this process works

This is the next steps code, which will take me to the third step:

@Override
    protected void onCreate(Bundle savedInstanceState) {
        super.onCreate(savedInstanceState);
        setContentView(R.layout.actiongenre);

        populateListView();
        registerClickCallback();

    }

    private void registerClickCallback() {

ListView list = (ListView)findViewById(R.id.listViewActionSubgenres);

        list.setOnItemClickListener(new AdapterView.OnItemClickListener() {

            @Override
            public void onItemClick(AdapterView parent, View view,
                    int position, long id) {

                Intent intent;
                switch(position)
                {
                case 0:
                    intent = new Intent(ActiongenreActivity.this,Actioncomedyactivity.class);
                    startActivity(intent);
                    break;
                case 1:
                    intent = new Intent(ActiongenreActivity.this,Actionadventureactivity.class);
                    startActivity(intent);
                    break;
                case 2:
                    intent = new Intent(ActiongenreActivity.this,ActionWesternActivity.class);
                    startActivity(intent);
                    break;
                case 3:
                    intent = new Intent(ActiongenreActivity.this,ActiondramaActivity.class);
                    startActivity(intent);
                    break;
                case 4:
                    intent = new Intent(ActiongenreActivity.this,ActionthrillerActivity.class);
                    startActivity(intent);
                    break;
                case 5:
                    intent = new Intent(ActiongenreActivity.this,ActionfantaasyActivity.class);
                    startActivity(intent);
                    break;
                default:
                    break;
                }

            }
        });



    }
    private void populateListView() {
        String[] myItems = {"Komedi","Äventyr","Western","Drama","Thriller","Fantasi"};
        ArrayAdapter adapter = new ArrayAdapter(this,R.layout.the_list,myItems);
        ListView list = (ListView)findViewById(R.id.listViewActionSubgenres);
        list.setAdapter(adapter);
    }


}

But its this third step which doesnt work, and as you can see the code for the first process is almost identical to the second

Your code has Actioncomedyactivity while the manifest has ActioncomedyActivity. The a vs. A matters.
