Pressing back button in child activity-> main activity in app?

I'm using SlidingMenu and 3/4 navigation is done by it. And if I want to go back I have to went through all these activities which I open before. I would like to change it to such that closing any child activity (not a main activity) sends me to app main activity, and if then I press back it exit app. Simple as that.

I open new activities that way:

Intent LinieActivity = new Intent(Oznaczenia.this, Linie.class);
            startActivity(LinieActivity);

and I have tried putting in my Manifest such thing:

<activity
        android:name=".childActivity"
        android:label="some name">
        <meta-data
        android:name="android.support.PARENT_ACTIVITY"
        android:value="com.example.MainActivity" />
    </activity>

Once you are done with an activity, you can call the command finish(); to close that page. So I would call the next page I want to open using an intent, then after that call finish(); and the page will close.

ItemPage ItemPage = new ItemPage();
Intent i = new Intent(context, ItemPage.class);
startActivity(i);
finish();

When you hit the back button, none of the pages you called finish on will be there.

Hey here is the code for back button pressed you can mange if you want to exit you can otherwise you can go to your main activity

   @Override
    public void onBackPressed() {
    new AlertDialog.Builder(this)
    .setTitle("Exit App?")
    .setMessage("Are you sure you want to exit?")
    .setNegativeButton(android.R.string.no, null)
    .setPositiveButton(android.R.string.yes, new OnClickListener() {

        public void onClick(DialogInterface arg0, int arg1) {
            WelcomeActivity.super.onBackPressed();
