Question

Given an Android app that does NOT require any of the features that need to be declared in the

<uses-feature> 

element of the manifest, is it best to omit this element entirely or include it with no attributes? Will either option have any different effects on your apps visibility/availability in the market?

Answer 1

From ‘s docs

Declaring a element is
informational only, meaning that the
Android system itself does not check
for matching feature support on the
device before installing an
application. However, note that other
services (such as Android Market) or
applications may check your
application’s
declarations as part of handling or
interacting with your application. For
this reason, it’s very important that
you declare all of the features (from
the list below) that your application
uses.

If you are not using any feature that needs to have a <uses-feature> in the manifest, just remove the whole tag.
