My application uses android native sip library, and I add this line to assure the app can be found only by devices support it:
<uses-feature android:name="android.hardware.sip.voip" android:required="true" />
On market publish page it said my app has these features:
android.hardware.MICROPHONE
android.hardware.screen.PORTRAIT
android.hardware.sip.VOIP
android.hardware.TOUCHSCREEN
android.hardware.WIFI
But the number of supported devices is 0.
If I remove sip feature, the number of supported devices is 3823.
Why did it happen? I am sure that at least my HTC new One can run it properly.
update
I found that even the official SipDemo sample project supports 0 devices!
