Android onActivityResult Callback for Unity

This is a sample code of sharing an image file and open the sharing UI.
=============================================================================
AndroidJavaClass unityPlayerClass = new AndroidJavaClass("com.unity3d.player.UnityPlayer");
AndroidJavaObject currentActivity = unityPlayerClass.GetStatic<AndroidJavaObject>("currentActivity");
AndroidJavaClass intentClass = new AndroidJavaClass("android.content.Intent");
AndroidJavaObject intentObject = new AndroidJavaObject("android.content.Intent");

intentObject.Call<AndroidJavaObject>("setAction", intentClass.GetStatic<string>("ACTION_SEND"));
intentObject.Call<AndroidJavaObject>("setType", GetSetType(setType) );

AndroidJavaClass fileProviderClass = new AndroidJavaClass("android.support.v4.content.FileProvider");
AndroidJavaObject unityContext = currentActivity.Call<AndroidJavaObject>("getApplicationContext");

string packageName = unityContext.Call<string>("getPackageName");
string authority = packageName + ".provider";

string[] paths = new string[] { Application.persistentDataPath + "/CustomFiles/" + fileName };
Debug.Log(paths[0]);

AndroidJavaObject fileObj = new AndroidJavaObject("java.io.File", paths[0]);
AndroidJavaObject uriObj = fileProviderClass.CallStatic<AndroidJavaObject>("getUriForFile", unityContext, authority, fileObj);
int FLAG_GRANT_READ_URI_PERMISSION = intentObject.GetStatic<int>("FLAG_GRANT_READ_URI_PERMISSION");
intentObject.Call<AndroidJavaObject>("addFlags", FLAG_GRANT_READ_URI_PERMISSION);
intentObject.Call<AndroidJavaObject>("putExtra", intentClass.GetStatic<string>("EXTRA_STREAM"), uriObj);
intentObject.Call<AndroidJavaObject>("putExtra", intentClass.GetStatic<string>("EXTRA_STREAM"), uriObj);
AndroidJavaObject jChooser = intentClass.CallStatic<AndroidJavaObject>("createChooser", intentObject, "");
currentActivity.Call("startActivity", jChooser);
=============================================================================
This code works but my problem is that, I don't know how to call the onActivityResult callback. Anyone know what line of code must be used to make it work?

 

I tried this but nothing happens

I changed currentActivity.Call("startActivity", jChooser);
to
currentActivity.Call("startActivityForResult", jChooser, 1);

Then, I create a subclass:

class UnityPlayerActivity : AndroidJavaProxy
{
public UnityPlayerActivity() : base("com.unity3d.player.UnityPlayer") { }

public void onActivityResult(int requestCode, int resultCode, AndroidJavaClass resultIntent)
{
Debug.Log("test");
}
}

it's not working. Any ideas?

 

Can You Please Give Me A Example

 

Sorry to raise an old thread but this seems unresolved. Did you ever get an example of sort this out? I am trying to do the same. I want to send a callback through unity to capture the activity results.

 

I am also facing a similar issue, I created an instance of my plugin class from unity, which can access the UnityPlayerActivity context, I can call startActivity for result, but the onActivityResult never fires inside my code:

Code (CSharp):

1. /**
2.      * Initiates the Google Sign-In process.
3.      * This should be called from Unity to start the sign-in intent.
4.      * @param GameObjectName the GameObject to receive the callback message
5.      * @param UnityCallbackName the callback method to handle the login response, this method should accept GoogleSignInResponse
6.      */
7.     public void InitiateSignIn(String GameObjectName,String UnityCallbackName){
8.         try{
9.             Log.d("Native","Sign in called from unity");
10.             // Start the sign-in intent using the context.
11.             // For Unity plugin, you might need to call a Unity method to start the intent.
12.  
13.  
14.             Intent signInIntent = client.getSignInIntent();
15.             //signInIntent.setClass(context,AndroidGoogleSignIn.class);
16.             //context.startActivity(signInIntent);
17.             context.startActivityForResult(signInIntent,RC_SIGN_IN);
18.  
19.  
20.             //Set Callback Params for result
21.             this.GameObjectName = GameObjectName;
22.             this.UnityCallbackName = UnityCallbackName;
23.         }catch (ActivityNotFoundException e){
24.             Log.d("Native", e.getLocalizedMessage());
25.         }
26.     }
27.  
28.  
29. /**
30. * Override so that the callback can catch the return data.
31. * @param requestCode the code that tells the program which action is has return data
32. * @param resultCode a result code of the operation
33. * @param data the native intent
34. */
35. @Override
36. protected void onActivityResult(int requestCode, int resultCode, Intent data){
37.     try{
38.         Toast.makeText(context, "On Activity Result Hit", Toast.LENGTH_SHORT).show();
39.         Log.d("Native","Result Code: " + resultCode);
40.         if (requestCode == RC_SIGN_IN) {
41.             Task<GoogleSignInAccount> task = GoogleSignIn.getSignedInAccountFromIntent(data);
42.             handleSignInResult(task);
43.         }
44.     }catch(Exception e){
45.         Toast.makeText(context, "onActivityResult error", Toast.LENGTH_SHORT).show();
46.         Log.d("Native","onActivityResultError");
47.         Log.d("Native",e.getLocalizedMessage());
48.     }
49.  
50. }
51.  
52.  
53.  
54.  
55.  

 

Same problem.
Also try to create activity class that extends 'UnityPlayerActivity' and override 'onActivityResult', but I couldn't import com.unity3d.player.UnityPlayerActivity.
I just need to catch result of pin code intent
