从javascript调用Unity Android方法，反之亦然

Question

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.

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.

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 code call->java method->C# method

Edit: 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)

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

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

Answer 1

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 + "');

Thanks!
