    <p>I want to create some icon and button images to be used in android. The images can be uniformly scaled/stretched over the allocated layout space(no intricate definition of minimum size in regions etc). I would like to cover all the screen sizes and density range. </p> <p>(from <a href="http://developer.android.com/guide/practices/screens_support.html" rel="nofollow">link to Dev guide</a>) The range for the sizes of screens is small, normal large and extra large. For the denstieis it is ldpi, mdpi, hdpi, and xhdpi. So there are 4 sizes and 4 densities. Do I need to supply 4x4 different images? If I needed to, I could imagine configuring Adobe Illustrator to export this way, but is it necessary? </p> <p>What are the practical spacing between these options which reasonably cover the needs for sizes and densities in this case? A rule of thumb answer from experience would be appreciated if a more technical justification does not apply.</p> <p>(note: the corners are simple right angles) (in the Dev guide, <a href="http://developer.android.com/guide/practices/screens_support.html#qualifiers" rel="nofollow">link for qualifiers</a>, qualifiers are mentioned for Size as well as Density but in the examples for the resource folders no differentiation is made for the sizes which may be different which I find confusing. Or am I missing some fundamental understanding on how the sizes are being taken care of?) EDIT: From this <a href="http://developer.android.com/guide/practices/ui_guidelines/icon_design_launcher.html#size" rel="nofollow">link</a>, connected to @Budgie comment below for the icons there is a recommended size and density for icons. </p>

A row detail

Detail views are divided into sections. All the information in the data section comes from columns in the selected row. The other sections display data from other, related rows.

Related data can be related in a to-one or a to-many fashion. Captions of data related in a to-many fashion link to a list view showing a filtered view of the table.

Try moving around until you find a non-empty to-many entry and click on the label to get to one. You can move back to the root by clicking on the database name in the header.
