Problem of devices showing in traccar manager 1.3
Yes, they are not compatible. You need latest server version to be able to use Manager app.
Is there a way to use it with server 3.0 without update it ? because i need the 3.0 version.
like changing something in codes
There is no way to use it with version 3.0 without modifying the code of the app.
If possible, can you tell me the classes that i should change? and sorry for disturbing.
I guess you need to change API-related classes. Are you talking about iOS or Android or both?
Only android.
Check "WebService" interface. That's a good place to start, but there might be some other changes required as well. As far as I remember, version 3.0 doesn't even use REST API, so I'm not sure if you can use Retrofit at all.
I will try it.
Thank you for help and sorry for disturbing.
Sorry i don't know what i should change.
Here is the WebService Interface:
public interface WebService {
@FormUrlEncoded
@POST("/api/session")
Call<User> addSession(@Field("email") String email, @Field("password") String password);
@GET("/api/devices")
Call<List<Device>> getDevices();
}In DevicesFragment class:
@Override
public void onActivityCreated(Bundle savedInstanceState) {
super.onActivityCreated(savedInstanceState);
final MainApplication application = (MainApplication) getActivity().getApplication();
application.getServiceAsync(new MainApplication.GetServiceCallback() {
@Override
public void onServiceReady(OkHttpClient client, Retrofit retrofit, WebService service) {
service.getDevices().enqueue(new WebServiceCallback<List<Device>>(getContext()) {
@Override
public void onSuccess(Response<List<Device>> response) {
setListAdapter(new ArrayAdapter<>(application, R.layout.list_item, android.R.id.text1, response.body()));
}
});
}
});
}In MainFragment:
@Override
public void onActivityResult(int requestCode, int resultCode, Intent data) {
if (requestCode == REQUEST_DEVICE && resultCode == RESULT_SUCCESS) {
long deviceId = data.getLongExtra(DevicesFragment.EXTRA_DEVICE_ID, 0);
Position position = positions.get(deviceId);
if (position != null) {
map.moveCamera(CameraUpdateFactory.newLatLng(
new LatLng(position.getLatitude(), position.getLongitude())));
markers.get(deviceId).showInfoWindow();
}
}
}
@Override
public void onMapReady(GoogleMap googleMap) {
map = googleMap;
map.setInfoWindowAdapter(new GoogleMap.InfoWindowAdapter() {
@Override
public View getInfoWindow(Marker marker) {
return null;
}
@Override
public View getInfoContents(Marker marker) {
View view = getLayoutInflater(null).inflate(R.layout.view_info, null);
((TextView) view.findViewById(R.id.title)).setText(marker.getTitle());
((TextView) view.findViewById(R.id.details)).setText(marker.getSnippet());
return view;
}
});
createWebSocket();
}
private String formatDetails(Position position) {
return new StringBuilder()
.append(getString(R.string.position_latitude)).append(": ")

});Can you help me please.
I don't think you can use Retrofit because it's not REST API. You need to implement API calls yourself or using some other library.
Ok, thanks.
Hi,
i have traccar server 3.0 and traccar manager 1.3 and i think they are not compatible because when i use "demo.traccar.com" in manager it work good but when i use my own server i can't show the devices.
i think because of compatibility between server 3.0 and manager 1.3 in database.
there is a solutions to that or no ? and thanks in advance.
