The image size of action bar in android app

Question

In android app, I would like to fix an action bar to the bottom of the screen.

The action bar has 6 icons.

I wrote down the following code.

In Galaxy Note3(Andoid4.4.2) it goes well. However, in Experia SOL21(Android4.1.2), the icon size is not adjusted to the appropriate size like below image.

Could you tell me how to fix this problem?

[My code]

in AndroidManifest.xml

    <activity
        android:name="com.myapp.DetailActivity"
        android:uiOptions="splitActionBarWhenNarrow" >
        <meta-data
            android:name="android.support.UI_OPTIONS"
            android:value="splitActionBarWhenNarrow" />
    </activity>

in Activity.java

 @Override
 public boolean onCreateOptionsMenu(Menu menu) {

    MenuItem actionItemBack = menu.add("Back");
    MenuItem actionItemForward = menu.add("Forward");
    MenuItem actionItemLine = menu.add("Twitter");
    MenuItem actionItemTw = menu.add("icon4");
    MenuItem actionItemFb = menu.add("icon5");
    MenuItem actionItemFav = menu.add("icon6");

    actionItemBack.setShowAsAction(MenuItem.SHOW_AS_ACTION_ALWAYS);
    actionItemForward.setShowAsAction(MenuItem.SHOW_AS_ACTION_ALWAYS);
    actionItemLine.setShowAsAction(MenuItem.SHOW_AS_ACTION_ALWAYS);
    actionItemTw.setShowAsAction(MenuItem.SHOW_AS_ACTION_ALWAYS);
    actionItemFb.setShowAsAction(MenuItem.SHOW_AS_ACTION_ALWAYS);
    actionItemFav.setShowAsAction(MenuItem.SHOW_AS_ACTION_ALWAYS);

    actionItemBack.setIcon(R.drawable.back);
    actionItemForward.setIcon(R.drawable.next);
    actionItemLine.setIcon(R.drawable.twitter);
    actionItemTw.setIcon(R.drawable.icon4);
    actionItemFb.setIcon(R.drawable.icon5);
    actionItemFav.setIcon(R.drawable.icon6);

    return true;
}

you have to get different size of images like

48*48 size image put in drawable-hdpi folder.

32*32 size image put in drawable-mdpi folder.

64*64 size image put in drawable-xhdpi folder.

96*96 size image put in drawable-xxhdpi folder.
