Question

I am often getting confused with the image sizes and button sizes that I am using for the android app.

I know that the buttons and images must be placed in folders such as drawable, drawable-ldpi, drawable-mdpi, drawable-hdpi, drawable-xhdpi but i am not clear the about the sizes to be mentioned in those folders that used for the app.

Please help me in explaining this. For example, if I am using a background image for my app, then what must be the size of the image in default and in each folder what sizes to be placed.

In case of the layout I know that I have to use folders such as layout, layout-large, layout-small, layout-xlarge. For example in this folder I am having the following xml code

<?xml version="1.0" encoding="utf-8"?>
<LinearLayout xmlns:android="http://schemas.android.com/apk/res/android"
    android:orientation="vertical"
    android:layout_width="fill_parent"
    android:layout_height="fill_parent"
    android:background="@drawable/splash_screen"
    >
</LinearLayout>

For the android:background image for each layout, from which folder is the image fetched?
