Hi,

Most apps can be found on Google Play but there are others elsewhere, like Gmail or Skype (I only use these that are not from Google Play). By the way I am developing an own app for Android (similar to this one: http://www.voip-sip-sdk.com/p_456-vo...tion-voip.html), that will be a VoIP app. After it is done I am considering to place it on Google Play.
