Quit confirmation screen for android game with unity

Question

I'm making my own android game with unity, I want to make quit confirmation screen just like this one:

How is it possible to make it using c#?

You have to use an alert dialog. See [this](http://www.androidhive.info/2011/09/how-to-show-alert-dialog-in-android/) — Jorel Amthor, Jan 29 '16 at 13:35

The type or namespace name `AlertDialog' could not be found. Are you missing a using directive or an assembly reference? — Juustosta Löytyy, Jan 29 '16 at 13:50
Yeah, what's the problem, it doesn't know what's AlertDialog — Juustosta Löytyy, Jan 29 '16 at 13:52
You could built it with the unity ui system and just call Application.Quit() when user presses the quit button. (Unless you want that native android look.) — JeanLuc, Jan 29 '16 at 16:16

You can access to java.lang.Class and the java.lang.Object like this.

AndroidJavaClass unityPlayer = new AndroidJavaClass ("com.unity3d.player.UnityPlayer");
AndroidJavaObject activity = unityPlayer.GetStatic<  AndroidJavaObject >  ("currentActivity");

from this you should be able to set GUI components, buttons, and click listeners to imitate an alert dialog

See this post for further understanding

I copied the code, still the same problem https://gyazo.com/3d9a782501ceaeebf5b09ba894713f72 – Juustosta Löytyy Jan 29 '16 at 14:13
I guess it could means you're missing a reference dont you ? "if you want to say create a custom dialog you can create a jar library which has the required code and access the classes in the jar by using the same technique. " Have you referenced a jar with the code needed ? – Jorel Amthor Jan 29 '16 at 14:15
I'm not sure, I'm using visual studio that came with unity – Juustosta Löytyy Jan 29 '16 at 14:18
You have to make a jar with the AlertDialog java code in it, add the jar as a reference to your project, and then you'll be able to manipulate it. What is a [JAR](https://en.wikipedia.org/wiki/JAR_(file_format)) ? – Jorel Amthor Jan 29 '16 at 14:19

I made a small example for you

attach the following script on a gameobject (the canvas for example)
add to the root of your normal ui (a panel for example) a CanvasGroup component
add to the root of your quit confirmation ui (a panel for example) a CanvasGroup component
Link the two canvas group to the gameobject where you put the script
For each button (Quit, Confirm yes, Confirm No) add in the Inspector a onclick event to the script corresponding method

That is all i think (I tried to comment a bit the code for reference), Reference

public class QuitHandler : MonoBehaviour { 

 public CanvasGroup uiCanvasGroup;
 public CanvasGroup confirmQuitCanvasGroup;

 // Use this for initialization
 private void Awake()
 {
     //disable the quit confirmation panel
     DoConfirmQuitNo();
 }

 /// <summary>
 /// Called if clicked on No (confirmation)
 /// </summary>
 public void DoConfirmQuitNo()
 {
     Debug.Log("Back to the game");

     //enable the normal ui
     uiCanvasGroup.alpha = 1;
     uiCanvasGroup.interactable = true;
     uiCanvasGroup.blocksRaycasts = true;

     //disable the confirmation quit ui
     confirmQuitCanvasGroup.alpha = 0;
     confirmQuitCanvasGroup.interactable = false;
     confirmQuitCanvasGroup.blocksRaycasts = false;
 }

 /// <summary>
 /// Called if clicked on Yes (confirmation)
 /// </summary>
 public void DoConfirmQuitYes()
 {
     Debug.Log("Ok bye bye");
     Application.Quit();
 }

 /// <summary>
 /// Called if clicked on Quit
 /// </summary>
 public void DoQuit()
 {
     Debug.Log("Check form quit confirmation");

     //reduce the visibility of normal UI, and disable all interraction
     uiCanvasGroup.alpha = 0.5f;
     uiCanvasGroup.interactable = false;
     uiCanvasGroup.blocksRaycasts = false;

     //enable interraction with confirmation gui and make visible
     confirmQuitCanvasGroup.alpha = 1;
     confirmQuitCanvasGroup.interactable = true;
     confirmQuitCanvasGroup.blocksRaycasts = true;
 }

 /// <summary>
 /// Called if clicked on new game (example)
 /// </summary>
 public void DoNewGame()
 {
     Debug.Log("Launch a new game");
 }
