安卓接入unity工程

自己记录用，版本unity2017.1.1f1，Androidstudio3.0，vuforia

单独的写好的unity程序，注意横竖屏，如果不对应会闪退

创建Androidstudio工程，然后复制jar包进入，我的unity版本的jar包路径为D:\unity\Editor\Data\PlaybackEngines\AndroidPlayer\Variations\mono\Release\Classes

复制class.jar到工程的libs里，然后复制vuforia里面的两个jar包。unity工程打包apk，之后解压，复制里面的assets和libs里的armeabi-v7a到工程里

jar包选中右键添加到工程，然后修改mainactivity。

public class MainActivity extends UnityPlayerNativeActivity {

    private LinearLayout scan;
    protected UnityPlayer mUnityPlayer;

    @Override
    protected void onCreate(Bundle savedInstanceState) {
        super.onCreate(savedInstanceState);
        setContentView(R.layout.activity_main);

        mUnityPlayer = new UnityPlayer(this);

        if (mUnityPlayer.getSettings ().getBoolean ("hide_status_bar", true))
            getWindow ().setFlags (WindowManager.LayoutParams.FLAG_FULLSCREEN,
                    WindowManager.LayoutParams.FLAG_FULLSCREEN);

        int glesMode = mUnityPlayer.getSettings().getInt("gles_mode", 1);
        boolean trueColor8888 = false;
        // UnityPlayer.init()方法需要在将view附加到layout之前调用。它将会调用native code
        mUnityPlayer.init(glesMode, trueColor8888);

        scan=(LinearLayout)findViewById(R.id.scan);
        View view = mUnityPlayer.getView();
        scan.addView(view);
    }

继承unity里的activity，然后oncreate里配置的全屏之类的东西，不是很懂

再之后修改xml文件

<?xml version="1.0" encoding="utf-8"?>
<manifest xmlns:android="http://schemas.android.com/apk/res/android"
    package="com.djzz.app.unitytest"
    android:installLocation="preferExternal">

            </intent-filter>

        </activity>

        <activity android:name=".SecondActivity"
            android:screenOrientation="portrait"

        <uses-library android:name="com.osterhoutgroup.api.ext" android:required="false" />

    </application>

</manifest>

权限4个都要写，是vuforia必备的，不写能调起程序但是vuforia不好使，下面的activity是直接复制过来的videoplayer看着是红色的，感觉不是必要的，下面两个library的需要添加上，横竖屏要注意，接下来是互相的调用了。

先写unity调用java的

java代码

public void test(String name)
    {
        String str = "aaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaa" + name;
        System.out.println(str);
    }

unity代码，传了一个参数

AndroidJavaClass jc = new AndroidJavaClass("com.unity3d.player.UnityPlayer");
AndroidJavaObject jo = jc.GetStatic<AndroidJavaObject>("currentActivity");
jo.Call("test","测试测试");

接下来是java调用unity

java代码，参数是gameobject物体名，方法名，方法参数

public void callUnityFunc(String _objName , String _funcStr, String _content)
    {
        UnityPlayer.UnitySendMessage(_objName, _funcStr,  _content);
    }

callUnityFunc("gameControl" , "test", "ceshi");

unity代码

public void test(string str){
		text.text = str;
	}
