从javascript调用Unity Android方法，反之亦然 [英] Call Unity Android Method from javascript and vice-versa

问题描述

我正在使用统一的游戏引擎开发一个 android应用，该应用需要通过JavaScript(一个也在移动浏览器中打开的网站)进行某些功能调用，反之亦然.像JavaScript/html一样会打开我的应用程序.然后，它可以命令我的APK中的对象(播放器或相机)在3D环境中移至特定位置.或者相反，该应用程序可以在网站上调用JavaScript方法，该网站可以在同一设备上的移动浏览器中打开.

I am developing an android app using unity game-engine that require some function calling from JavaScript(A website which also open in a mobile browser) and vice-versa. Like a JavaScript/html will open my app. Then it can order an object in my APK (the player or camera) to go at specific position in a 3D environment. Or conversely the app can call the JavaScript method at the Website which is open in the mobile browser on the same device.

我能够使用

I am able to successfully open my unity based APK from a web-page using this answer at Stackoverflow (Thanks to @romaroma) but I don't have any idea that how to do other stuff.

似乎我首先必须统一编写一个函数，然后从Java调用该函数，然后该函数将由JavaScript调用

It seems that first I have to write a function in unity, then call that function from java and then that function will be called by the JavaScript

JavaScript代码调用-> java方法-> C#方法

感谢@ Mahdi-Malv的评论，我发现Java到C#和C#到Java调用的工作方式(未经测试，但似乎可以工作)

Thanks to @Mahdi-Malv comment, i found that how Java to C# and C# to Java Calling can work (not tested but seems it will work)

如果要从Java调用c#，请使用UnitySendMessage()函数. 如果要从c#调用Java，请使用AndroidJavaObject和 AndroidJavaClass

If you want to call a c# from java, use UnitySendMessage() function. If you want to call java from c#, use AndroidJavaObject and AndroidJavaClass

现在，答案仍然是不完整的，我的Andriod应用将如何与网页(javascript)通信.

Now the answer is still incomplete that how do my andriod app will communicate with a web page (javascript).

推荐答案

您可以在下面的行中从Android本机代码调用用javascript编写的方法.

You can call the methods which are written in javascript from Android native code by below line.

webView.loadUrl("javascript:<method_name>(<parameters_if_any>)");

// for e.g. javascript:populateScanResult('" + contents + "');
