JavaFx Turn-based Multiplayer Application with Google Service - javafx

Question

Now I am using Gluon plugin and it is very helpful to start working with JavaFXPorts. I have my application ready and I can use it on computers and phones. I tested on phone with system android. Application is working good but only with my server.
I take care of the different resolutions and I think that it is good for now.
I want to have Turn-based Multiplayer Application but I have still big problem with using Google Play Service. Tutorial which show how to use this services for turn-based multiplayer application is written in pure android and use Activity. My question is maybe very simple but If I have my application view from "fxml" how to use it as an tutorial Activity?
I want to do auto-matching for my application and next I want override method takeTurn() to suit it to my application.
For example, how can I change thing like that (code below) to application in JavaFX?
I must use google services from my JavaFX(src/main/java folder) class in addition AndroidPlatformProvider.java and all methods must be in src/android/java folder. I know that I must use PlatformService and PlatformProvider. I did it as in the examples: HelloPlatform and SMSTracker .
I use methods from my interface PlatformProvider but application still crashes. :(
I only use Provider from my code of JavaFX and I don't have android Activity. I don't know how to use these method without Activity or View:
- public void onActivityResult(int request, int response, Intent data)
- public void playTurn(View view)
Can I call from google service methods to methods from my controller for view (fxml).
I don't know how these methods should working with JavaFX.
public class TbmpGameActivity extends Activity {
...
#Override
public void onActivityResult(int request, int response, Intent data) {
super.onActivityResult(request, response, data);
...
if (request == RC_SELECT_PLAYERS) {
if (response != Activity.RESULT_OK) {
// user canceled
return;
}
// Get the invitee list.
final ArrayList<String> invitees =
data.getStringArrayListExtra(Games.EXTRA_PLAYER_IDS);
// Get auto-match criteria.
Bundle autoMatchCriteria = null;
int minAutoMatchPlayers = data.getIntExtra(
Multiplayer.EXTRA_MIN_AUTOMATCH_PLAYERS, 0);
int maxAutoMatchPlayers = data.getIntExtra(
Multiplayer.EXTRA_MAX_AUTOMATCH_PLAYERS, 0);
if (minAutoMatchPlayers > 0) {
autoMatchCriteria = RoomConfig.createAutoMatchCriteria(
minAutoMatchPlayers, maxAutoMatchPlayers, 0);
} else {
autoMatchCriteria = null;
}
TurnBasedMatchConfig tbmc = TurnBasedMatchConfig.builder()
.addInvitedPlayers(invitees)
.setAutoMatchCriteria(autoMatchCriteria)
.build();
// Create and start the match.
Games.TurnBasedMultiplayer
.createMatch(mGoogleApiClient, tbmc)
.setResultCallback(new MatchInitiatedCallback());
}
}
}
or something like that:
// Call this method when a player has completed his turn and wants to
// go onto the next player, which may be himself.
public void playTurn(View view) {
// Get the next participant in the game-defined way, possibly round-robin.
String nextParticipantId = getNextParticipantId();
// Get the updated state. In this example, we simply retrieve a
// text string from the view. In your game, there may be more
// complicated state.
mTurnData = mDataView.getText().toString();
// At this point, you might want to show a waiting dialog so that
// the current player does not try to submit turn actions twice.
showSpinner();
// Invoke the next turn. We are converting our data to a byte array.
Games.TurnBasedMultiplayer
.takeTurn(mGoogleApiClient, mMatch.getMatchId(),
mTurnData.getBytes(Charset.forName("UTF-16")),
nextParticipantId)
.setResultCallback(this);
}

Latest version of the jfxmobile plugin (1.0.3) includes recent changes in Dalvik SDK that contains the port of JavaFX 8 to android.
In FXActivity class, it has been added a very convenient method to listen to results of intents: setOnActivityResultHandler().
This means you shouldn't add new activities to your app, and only use FXActivity. You should add an Intent to it, and set a proper result handler to the FXActivity.
Have a look at this recent post at Gluon's site. It explains how to access native services, based on the case of taking a picture with the device's camera, and waiting to get the result of it to resume the app.
Basically, this is what it is required in this case:
public void takePicture() {
// create intent
Intent intent = new Intent(MediaStore.ACTION_IMAGE_CAPTURE);
...
// Add result handler
FXActivity.getInstance().setOnActivityResultHandler((requestCode, resultCode, data) -> {
if (requestCode == TAKE_PICTURE && resultCode == RESULT_OK) {
...
}
});
// launch activity
FXActivity.getInstance().startActivityForResult(intent, TAKE_PICTURE);
}
Try this approach with your app.
