Could you guide how can I check user existense without login on Android? I looked for solution in documentation but find this functionality only for iOS http://devcenter.kinvey.com/ios/guides/users#userexists
One solution would be to have an implicitKinveyClient created: implicitKinveyClient = new Client.Builder(appKey, appSecret, this.getApplicationContext()).build();
After that with this client you can make a user discovery with a user lookup criteria set for username.

Unfortunately we don't yet have support in the Android library for this as we do in the iOS library, but as a workaround you can use a custom endpoint to hit the REST API endpoint. See http://devcenter.kinvey.com/rest/guides/users#userexists
