I have an android library project and imported the library project in the Unity project. Now, I want to implement a callback in Unity project, which will execute according to the response given by the android library project. I mean to say, Call Script File method from UnityPlayerActivity (Android Project).
Currently I am using below line of code but nothing happens:
UnityPlayer.UnitySendMessage("Main Camera","showMessage",errorMessage);
Main Camera
is my Game Object. showMessage
is message name in Script File.
Message
is message which will be displayed in Unity through Android Activity.
Please check my below code Unity Script File and Android Activity.
Unity Script File:
using UnityEngine;
using System.Collections;
public class scriptfile : MonoBehaviour {
// Use this for initialization
void Start () {
AndroidJavaClass jc = new AndroidJavaClass("com.unity3d.player.UnityPlayer");
AndroidJavaObject jo = jc.GetStatic<AndroidJavaObject>("currentActivity");
jo.Call("shareText","236","236");
}
void showMessage(string message){
print ("hello");
Debug.Log ("hello");
}
}
Android File UnityPlayerActivity:
/**
* Created by CH-E01073 on 28-09-2015.
*/
public class MainAct extends UnityPlayerActivity implements RegistrationListener,BOffersListener {
Context context;
SharedPreferences prefs ;
String AppIds="";
String PublisherIDs="";
public void shareText(String AppId,String PublisherID) {
context=MainAct.this;
prefs = PreferenceManager
.getDefaultSharedPreferences(context);
Log.e("AppID", AppId);
Log.e("PublisherID",PublisherID);
AppIds=AppId;
PublisherIDs=PublisherID;
runOnUiThread(new Runnable() {
@Override
public void run() {
UnityPlayer.UnitySendMessage("Main Camera","showMessage","Start UI Thread");
if (prefs.getString(FreeBConstants.ID, null) == null
|| prefs.getString(FreeBConstants.ID, null).equals("")
|| !Build.VERSION.RELEASE.equals(prefs.getString(
FreeBConstants.VERSION, null))
|| !FreeBCommonUtility.getDeviceId(context).equals(
(prefs.getString(FreeBConstants.DEVICE_ID, null)))) {
BSDKLogger.enableLogging(true);
SDKRegistration.initialize(MainAct.this, getApplicationContext(), AppIds,PublisherIDs);
}else{
Offers Offers = new Offers(MainAct.this);
Offers.setOnFreeBOffersListener(MainAct.this);
Offers.setTitle(
"Pick Any Offer to unlock your premium features",
"#FFFFFF", "#FF6D00");
}
}
});
}
@Override
public void onOffersLoaded(String code,String freeBOffers) {
CommonUtility.showToast(getApplicationContext(), code);
UnityPlayer.UnitySendMessage("Main Camera","showMessage",freeBOffers);
}
@Override
public void onShowOffers() {
UnityPlayer.UnitySendMessage("Main Camera","showMessage","Show Offers");
}
@Override
public void noOfferInstalled(String s, String s2) {
}
@Override
public void onLeaveApplication(String s, String s2) {
}
@Override
public void onDialogDismiss(String s) {
}
@Override
public void onOffersFailed(String code, String errorMessage) {
FreeBCommonUtility.showToast(getApplicationContext(), errorMessage);
UnityPlayer.UnitySendMessage("Main Camera","showMessage",errorMessage);
}
@Override
public void onOffersInstallSuccess(String code, String errorMessage) {
FreeBCommonUtility.showToast(getApplicationContext(), errorMessage);
}
@Override
public void onOffersInstallFailure(String code, String errorMessage) {
FreeBCommonUtility.showToast(getApplicationContext(), errorMessage);
}
@Override
public void onRegistrationFailed(String code, String errorMessage) {
FreeBCommonUtility.showToast(getApplicationContext(), errorMessage);
UnityPlayer.UnitySendMessage("Main Camera","showMessage",errorMessage);
}
@Override
public void onRegistrationSuccess(String code, String errorMessage) {
// FreeBCommonUtility.showToast(getApplicationContext(), errorMessage);
Log.e("SUCCESS", errorMessage);
// TODO Auto-generated method stub
UnityPlayer.UnitySendMessage("Main Camera","showMessage",errorMessage);
Offers Offers = new Offers(MainAct.this);
Offers.setOnFreeBOffersListener(MainAct.this);
Offers.setTitle(
"Pick Any Offer to unlock your premium features",
"#FFFFFF", "#FF6D00");
}
}
Can anyone help me to get rid of this issue?
Another option will be to implement an interface callback using AndroidJavaProxy. Instead of using UnitySendMessage, you can simply have an Interface callback in your java code and then implement this interface in C# using AndroidJavaProxy and pass it to the Java method in order to receive messages back.
Create your Java interface:
package com.example.android;
public interface PluginCallback {
public void onSuccess(String videoPath);
public void onError(String errorMessage);
}
Call the passed listener/callback to return messages
public void myPluginMethod(PluginCallback callback) {
// Do something
callback.onSuccess("onSuccess");
// Do something horrible
callback.onError("onError");
}
Implement the interface in C#
class AndroidPluginCallback : AndroidJavaProxy
{
public AndroidPluginCallback() : base("com.example.android.PluginCallback") { }
public void onSuccess(string videoPath) {
Debug.Log("ENTER callback onSuccess: " + videoPath);
}
public void onError(string errorMessage)
{
Debug.Log("ENTER callback onError: " + errorMessage);
}
}
Pass the C# interface to the Java method
AndroidJavaObject pluginClass = new AndroidJavaObject("com.example.android.MyPlugin");
pluginClass.Call("myPluginMethod", new AndroidPluginCallback());
