I have an app that uses (but does not require) telephony.
So (as described by Mark Murphy here:
http://commonsware.com/blog/2011/02/25/xoom-permissions-android-market.html)
I add the following line to the manifest:
<uses-feature
android:name="android.hardware.telephony" android:required="false" />
and then check for the feature at runtime using:
private static boolean hasFeature(String feature, Context context) {
FeatureInfo[] featureInfos =
context.getPackageManager().getSystemAvailableFeatures();
for (FeatureInfo fi : featureInfos) {
if (feature.equals(fi.name)) {
return true;
}
}
return false;
}
However, I notice this does not work (returns false) for some devices that
definitely do have telephony (e.g. HTC Legend and Motorola Milestone). In
both cases, they are running SDK 7, so I wonder whether this particular
feature is an SDK 8+ thing?
