<p>Android powers millions of phones, tablets, and other devices in a wide variety of screen sizes and
|
|
form factors. By taking advantage of Android's flexible layout system, you can create apps that
|
|
gracefully scale from large tablets to smaller phones.</p>

<h4>Be flexible</h4>
|

<p>Stretch and compress your layouts to accommodate various heights and widths.</p>

<h4>Optimize layouts</h4>
|
|
<p>On larger devices, take advantage of extra screen real estate. Create compound views that combine
|
|
multiple views to reveal more content and ease navigation.</p>

<h4>Assets for all</h4>
|
|
<p>Provide resources for different screen densities (<acronym title="Dots per inch">DPI</acronym>) to
|
|
ensure that your app looks great on any device.</p>

<h4>Strategies</h4>
|
|
<p>So where do you begin when designing for multiple screens? One approach is to work in the base
|
|
standard (normal size and <acronym title="Medium density (160 dpi)">MDPI</acronym>) and scale it up or
|
|
down for the other buckets. Another approach is to start with the device with the largest screen
|
|
size, and then scale down and figure out the UI compromises you'll need to make on smaller screens.</p>
