Answer 1

Hi Orhan,

You can use Location Service to get location of players in android and can use Google Map to show them on Map. Here is a tutorial for Google Map Sample integration in Android.

You can use AppWarp API's to create real time multiplayer game.

Let me know if it helps.

Thanks

Thanks for answer,
I use Google Map V2. I can get users location and show the map but I can't get user location in real time. I try to use AppWarp for real time multiplayer game. I dont know to use Appwarp for location game .

As you are using location services, whenever player location is changed you can send location coordinate to other player in so that you will be able to show it on opponent's map.

I try to edit Fruity Monster Multiplayer game . I can make a room .Other user can join the room.I can show first user location but dont show the other user in the map. I should solve isMine functions. (I can update latitude and longitude in sendupdate Event )
public void addMorePlayer(boolean isMine, String userName){
        if(userMap.get(userName)!=null){// if already in room
            return;
        }
        Log.d("userNameGame", userName);
        char index =  userName.charAt(userName.length()-1);
       
        if(index=='1'){
            canavar="monster1";
        }else if(index=='2'){
            canavar="monster2";
        }else if(index=='3'){
            canavar="monster3";
        }else if(index=='4'){
            canavar="monster4";
        }
       
       
        User user = new User(point);
       
        userMap.put(userName, user);
        if(isMine){
           
             
        }
    }

Whenever you send location co-ordinate mapped with username  in a room you will receive it in onUpdatePeersReceived method, once you will receive location and username, you can show locate player on Google Map.

thanks a lot for your response,
I do not know exactly which method of use. The first time I do a multiplayer game. have to go through what functions. And I continue using locationchanged?I use this class,
String kullanici_adi;

You are using right API, in sendChat you are sending player location and on ChatReceived you are getting the location of that player. After that you have to show the location on your Google map.
Can you please specify more about your requirements.
