Question

I am creating layouts for my app, and as I understand the above screen resolution is the threshold resolution and devices below it are extremely rare or too cheap, how can I detect a device which does not comply with this resolution

Answer 1

Use this element in the Manifest file
<screen android:screenSize=["small" | "normal" | "large" | "xlarge"]

<compatible-screens>
 <screen android:screenSize="small"/>
 <screen android:screenSize="normal"/>
 <screen android:screenSize="large"/>
 <screen android:screenSize="xlarge"/>
</compatible-screens>

small screens are at least 426dp x 320dp
