Author:- Tushar Sonu Lambole

1. Before start this steps will require UnityPlayer classes.Jar

in Mac will find at location "/Applications/Unity/Unity.app/Contents/PlaybackEngines/

AndroidPlayer/bin"

2. Right-click on the project in Eclipse, go to Properties > Java Build Path > Libraries

3. Create new classActivity paste the following code 

import java.io.File;

import java.io.FileOutputStream;

import java.io.IOException;

import java.io.InputStream;

import java.io.OutputStream;

import java.net.URL;

import android.app.AlertDialog;

import android.content.Intent;

import android.net.Uri;

import android.os.Bundle;

import android.os.Environment;

import android.widget.Toast;

import com.unity3d.player.UnityPlayer;

import com.unity3d.player.UnityPlayerActivity;

public class RootActivity extends UnityPlayerActivity {

 static UnityPlayerActivity instance;

 public static UnityPlayerActivity getInstance() {

  return instance;

 }

 @Override

 protected void onCreate(Bundle savedInstanceState) {

  instance = this;

  super.onCreate(savedInstanceState);

 }

 public void showMessage(final String message) {

  this.runOnUiThread(new Runnable() {

   @Override

   public void run() {

    Toast.makeText(RootActivity.this, message, Toast.LENGTH_LONG)

      .show();

   }

  });

 }

 public void SocialMessageAdvanced(String message, String subject,

   String url, String img) {

  

  //showMessage(img);

  Intent sendIntent = new Intent(android.content.Intent.ACTION_SEND);

  if (url != null && url.length() > 0) {

   if (message == null) {

    message = url;

   } else {

    message = message + " " + url;

   }

  }

  try {

   doSendIntent(message, subject, img);

  } catch (IOException e) {

   e.printStackTrace();

  }

  UnityPlayer.currentActivity.startActivity(sendIntent);

 }

 private void doSendIntent(String text, String subject, String image)

   throws IOException {

  final Intent sendIntent = new Intent(android.content.Intent.ACTION_SEND);

  if (text != null && text.length() > 0) {

   sendIntent.putExtra(android.content.Intent.EXTRA_TEXT, text);

  }

  if (subject != null && subject.length() > 0) {

   sendIntent.putExtra(android.content.Intent.EXTRA_SUBJECT, subject);

  }

  if (image != null && image.length() > 0) {

   sendIntent.setType("image/*");

   sendIntent.putExtra(Intent.EXTRA_STREAM,

     Uri.fromFile(new File(image)));

   UnityPlayer.currentActivity.startActivity(sendIntent);

  } else {

   sendIntent.setType("text/plain");

   UnityPlayer.currentActivity.startActivity(sendIntent);

  }

 }

 public void SocialMessage(String message) {

  Intent sendIntent = new Intent(android.content.Intent.ACTION_SEND);

  sendIntent.setType("text/plain");

  sendIntent.putExtra(android.content.Intent.EXTRA_TEXT, message);

  UnityPlayer.currentActivity.startActivity(sendIntent);

 }

}

4. Right click on project and export as JAR file.

5. Open Unity3D application and paste the JAR from step 4 at location Assets/Plugins/Andoid

6. Open AndroidManifest.xml of unity3D file and make the changes as follows.

<?xml version="1.0" encoding="utf-8"?>

<manifest

    xmlns:android="http://schemas.android.com/apk/res/android"

                <category android:name="android.intent.category.LAUNCHER" />

            </intent-filter>

   

  </activity>

    </application>

</manifest>

7. Create new c# script in Unity3D as "AndroidMapInterface"

using UnityEngine;

using System.Collections;

public class AndroidMapInterface : MonoBehaviour {

 // Use this for initialization

 void Start () {

  //Initialize AndroidBridge

  AndroidBridge.Initialize();

  

  //Register Action

  AndroidBridge.OnXploarShowEvent += onXploarShowEvent;

  

 }

 public void CallSocialShare(string text)

 {

  AndroidBridge.CallSocialShare(text);

 }

 public void CallSocialShareAdvanced(string text, string subject, string url, string img)

 {

  AndroidBridge.CallSocialShareAdvanced(text, subject,url,img);

 }

 void onXploarShowEvent(string eventStr){

  Debug.Log("AndroidXploarInterface - onXploarShowEvent:"+eventStr);

  

 }

 void OnDestroy() {

  AndroidBridge.OnXploarShowEvent -= onXploarShowEvent;

 }

}

8. Create new C# script paste code

using UnityEngine;

using System.Collections;

using System.Runtime.InteropServices;

using System;

public class AndroidBridge : MonoBehaviour {

 public static event Action<string> OnXploarShowEvent;

 #if UNITY_IPHONE

  public struct ConfigStruct

  {

      public string tittle;

   public string message;

  }

  [DllImport ("__Internal")] private static extern void showAlertMessage(ref ConfigStruct conf);

  

 #endif

 // Init the class instance

 static AndroidBridge instance;

 public static void Initialize()

 {

  Debug.Log("Application Init");

  if (instance == null)

  {

   GameObject newGameObject = new GameObject("XploarBridge");

   newGameObject.AddComponent<AndroidBridge>();

   instance = newGameObject.GetComponent<AndroidBridge>();

  }

 }

 //Callback from Java or Objective-C which notifies an event

 //param : "EVENT_OPENED", "EVENT_CLOSED"

 //Method name starts small "o" and Event name is capital "O"

 void onXploarShowEvent(string eventStr){

  //Debug.Log("EasyCodeScanner - onScannerEvent eventStr=:"+eventStr);

  if (OnXploarShowEvent != null)

        {

            OnXploarShowEvent(eventStr);

        }

 }

 public static void CallSocialShare(string defaultTxt)

 {

  if (instance==null) 

  {

   Debug.Log("instance is null");

   Debug.LogError("AndroiddBridge - launchSilverpointMap error : ScriptObject  must be initialized before.");

   return;

  }

  

  

  #if UNITY_ANDROID 

    AndroidJavaClass jc = new AndroidJavaClass("com.unity3d.player.UnityPlayer"); 

   

    AndroidJavaObject jo = jc.GetStatic<AndroidJavaObject>("currentActivity"); 

     

    //Invoke the "SocialMessage" method in our Android Plugin Activity

    jo.Call("SocialMessage", defaultTxt);

  #endif

  

  #if UNITY_IPHONE 

   //IPHONE - Display the UIViewController

   ConfigStruct conf = new ConfigStruct();

   conf.tittle  = "Alert Message Tittle";

   conf.message = "First Attempt to call IOS plugin";

   showAlertMessage(ref conf);

  #endif

  

 }

 public static void CallSocialShareAdvanced(string defaultTxt, string subject, string url, string img)

 {

  if (instance==null) 

  {

   Debug.Log("instance is null");

   Debug.LogError("AndroiddBridge - error : ScriptObject  must be initialized before.");

   return;

  }

  

  

  #if UNITY_ANDROID 

    AndroidJavaClass jc = new AndroidJavaClass("com.unity3d.player.UnityPlayer"); 

   

    AndroidJavaObject jo = jc.GetStatic<AndroidJavaObject>("currentActivity"); 

     

    //Invoke the "SocialMessage" method in our Android Plugin Activity

    jo.Call("SocialMessageAdvanced", defaultTxt, subject, url, img);

  #endif

 }

}

9. Attach "AndroidMapInterface" script to the any gameobject

10. Call the methods as follows

AndroidMapInterface androidInterface = objectHavingScript.GetComponent<AndroidMapInterface>();

androidInterface.CallSocialShareAdvanced("Text",

"Subject","https://play.google.com/store/apps/details?id=com.tushar.ARBattleTank",

Application.persistentDataPath+"/Pic.jpg");

@end

Here your IOS code part ends. Copy the both the files "XploarIOSPlugin.h" and "XploarIOSPlugin.m" and paste at the location /Assets/Plugins/iOS of your Unity3D project.

---- In Unity3d ----------

1. Create new c# script name it as "IOSBridge" and paste the below cod

#if UNITY_IPHONE

public struct ConfigStruct

{

    public string tittle;

    public string message;

}

[DllImport ("__Internal")] private static extern void showAlertMessage(ref ConfigStruct conf);

public struct SocialSharingStruct

{

    public string text;

public string url;

public string image;

public string subject;

}

[DllImport ("__Internal")] private static extern void showSocialSharing(ref SocialSharingStruct conf);

#endif

public static void CallSocialShare(string title, string message)

{

#if UNITY_IPHONE

//IPHONE - Display the UIViewController

ConfigStruct conf = new ConfigStruct();

conf.tittle  = title;

conf.message = message;

showAlertMessage(ref conf);

#endif

}

public static void CallSocialShareAdvanced(string defaultTxt, string subject, string url, string img)

{

#if UNITY_IPHONE

//IPHONE - Display the UIViewController

SocialSharingStruct conf = new SocialSharingStruct();

conf.text = defaultTxt; 

conf.url = url;

conf.image = img;

conf.subject = subject;

showSocialSharing(ref conf);

#endif

}

2. Call above method CallSocialShare("This is Alert Tittle"," This is Message Text");

CallSocialShareAdvanced("AR Battle Tank"," AR Battle Tank Application link","https://play.google.com/store/apps/details?id=com.tushar.ARBattleTank","01.jpg");

"01.jpg" can be replace with any web url of image like
