How to know when a Retrofit call is finished

Is there a way of know when my Retrofit call has finished it's duty? I like know when all the data is received so the code can move on, like starting another activity or use data from the first call to make a second?

Ps.: I'm using an asynchronous request (.enqueue).

Edit:

getContact(){ 
//Get a contact List from the server    
    Call<List<ModelContact>> callM =  contactInterface.createRContact(listContact);
    callM.enqueue(new Callback<List<ModelContact>>() {
    @Override

    public void onResponse(Response<List<ModelContact>> response, Retrofit retrofit) {
        // Fetch the List from Response and save it on the local database
        }

    @Override
        public void onFailure(Throwable t) {
            Log.i("TAG", "Error: " + t.getMessage());
        }
    });

    //Gets a object containing some configurations
    Call<Configs> callC = contactInterface.getConfigs(Configs);
    callC.enqueue(new Callback<Configs>() {
    @Override

    public void onResponse(Response<Configs> response, Retrofit retrofit) {
        // Fetch the Configs object and save it on the database
        }

    @Override
        public void onFailure(Throwable t) {
            Log.i("TAG", "Error: " + t.getMessage());
        }
    });

    //Here I need to start a new activity after the calls
    Intent loginact = new Intent(TokenActivity.this, LoginActivity.class);
           startActivity(loginact);


}

Perhaps you can use two boolean flags and start the new intent outside of your getContact method.

Something like this:

public class MyActivity extends Activity {
    //lot of code omitted 
    private boolean cIsFinished;
    private boolean mIsFinished;

    private void getContact(){
      //create M and C 
      m.onResponse(){
        //do whatever you want with data and call startIntent
        mIsFinished=true;
        startIntent();
      }
      c.onResponse(){
        //do whatever you want with data and call startIntent
        cIsFinished=true;
        startIntent();
      }


    }
    private synchronized void startIntent(){
       if(cIsFinished && mIsFinished){
          //startIntentHere!
          Intent intent = new blah blah blah
       }

    }    
}

Move

//Gets a object containing some configurations
Call<Configs> callC = contactInterface.getConfigs(Configs);
callC.enqueue(new Callback<Configs>() {

    @Override
    public void onResponse(Response<Configs> response, Retrofit retrofit) {
    // Fetch the Configs object and save it on the database
       Intent loginact = new Intent(TokenActivity.this, LoginActivity.class);
       startActivity(loginact);
    }

    @Override
    public void onFailure(Throwable t) {
        Log.i("TAG", "Error: " + t.getMessage());
    }
});

inside callM 's onResponse method like this. That way firs callM will execute, whenever it finishes callC will execute, and whenever callC finishes it will throw the Intent.

getContact(){ 
    //Get a contact List from the server    
    Call<List<ModelContact>> callM =  contactInterface.createRContact(listContact);
    callM.enqueue(new Callback<List<ModelContact>>() {

    @Override    
    public void onResponse(Response<List<ModelContact>> response, Retrofit retrofit) {
        // Fetch the List from Response and save it on the local database
            //Gets a object containing some configurations
            Call<Configs> callC = contactInterface.getConfigs(Configs);
            callC.enqueue(new Callback<Configs>() {
                @Override
                public void onResponse(Response<Configs> response, Retrofit retrofit) {
                    //Fetch the Configs object and save it on the database
                    //Here I need to start a new activity after the calls
                    Intent loginact = new Intent(TokenActivity.this, LoginActivity.class);
                    startActivity(loginact);
                }

                @Override
                public void onFailure(Throwable t) {
                    Log.i("TAG", "Error: " + t.getMessage());
                }
            });
        }

        @Override
        public void onFailure(Throwable t) {
            Log.i("TAG", "Error: " + t.getMessage());
        }
    });    
  }

If you have any request depend each other, it'll be complex. You can do that with RxJava by using flatMap method to chain multiple request and avoid callback hell. it's pretty simple. You can learn it here.
