How to make a whatsapp video call with C# Unity

My Target: By pressing a button, a whatsapp video call to a specific person starts. I don't know Java well enough, so I would like to accomplish this via C# in Unity.

I tried to replicate this process by translating it into C#.

But there is something wrong, because once the button is pressed I can only access the whatsapp home.

I also added permissions to access contacts from the manifest.

I'm doing everything manually, so I pasted the script on android studio to find the _id of a specific contact that had the mimetype for whatsapp video calls.

So I tried to translate the call function via Unity's AndroidJavaClass:

Java Code:

 public void videoCall(String id){

           Intent intent = new Intent();

           intent.setAction(Intent.ACTION_VIEW);



           intent.setDataAndType(Uri.parse("content://com.android.contacts/data/" + id),

                   "vnd.android.cursor.item/vnd.com.whatsapp.video.call");

           intent.setPackage("com.whatsapp");



           startActivity(intent);

}

C# Code:

Code (CSharp):

1. public static class Intentions
2. {
3. static string id = "5576";
4. static string data_url = "content://com.android.contacts/data/" + id;
5. static string type_url = "vnd.android.cursor.item / vnd.com.whatsapp.video.call";
6.  
7. public static AndroidJavaClass unityPlayer = new AndroidJavaClass("com.unity3d.player.UnityPlayer");
8. public static AndroidJavaObject currentActivity = unityPlayer.GetStatic<AndroidJavaObject>
9. ("currentActivity");
10. public static AndroidJavaObject packageManager = currentActivity.Call<AndroidJavaObject>
11. ("getPackageManager");
12. public static AndroidJavaObject intent = packageManager.Call<AndroidJavaObject>
13. ("getLaunchIntentForPackage", "com.whatsapp");
14.  
15. public static AndroidJavaClass uriClass = new AndroidJavaClass("android.net.Uri");
16. public static AndroidJavaObject uriData = uriClass.CallStatic<AndroidJavaObject>("parse", data_url);
17.  
18. public static void Launch()
19. {
20.     intent.Call<AndroidJavaObject>("setAction", "android.intent.action.VIEW");
21.     intent.Call<AndroidJavaObject>("setDataAndType", uriData, type_url);
22.  
23.     if (IsAndroid())
24.     {
25.         currentActivity.Call("startActivity", intent);
26.     }
27. }
28.  
29. public static bool IsAndroid()
30. {
31. #if UNITY_ANDROID && !UNITY_EDITOR
32.     return true;
33. #else
34.     return false;
35. #endif
36. }
37. }

 

Hi, I'm new here and while I was experimenting with something similar on this FMWhatsApp Apk modified version of WhatsApp I found this script which was very useful to me and I think you should try this script.

You actually don’t need to do a plug-in thru Java but can Use C# directly from your Unity source code. Do this to make calling WhatsApp API call via REST interface.

String number = “16696661337”;
String url = "https://api.whatsapp.com/send?phone=" + number;
/*
mobile number is: 1-(669)666-1337, your final string will be:
https://api.whatsapp.com/send?phone=6696661337
*/
Application.OpenURL(url);
You can also send text messages too if you want to. Don’t forget to include your country code for the API to work as intended.

 

how can i send messages in whatsapp using unity

 

Thank you so much mate, this worked for me!

 

But it didn't worked when i try on modified version but worked with official one.
