• These are a sample Unity and a Android Studio project that communicate each other.
• The unity app can call android native API

In C# (Caller)

    AndroidManager.GetInstance().CallJavaFunc( "javaTestFunc", "UnityJavaJarTest" );

In Android (Callee)

    public void javaTestFunc(String strFromUnity) { 
        /* ... Do something here with java native api ... */ 
    }

In C# (Callee)

    void SetJavaLog(string strJavaLog)
  	{
  		strLog = strJavaLog;
  		_text.text = strLog;
  	}
