unity调用安卓arr方法

1、新建empty activity

2、新建new module，选Android libarary，新建新的java class

3、获得android中activity的方法：

安卓端：

public static Activity _unityActivity;
unity(){
    if(null==_unityActivity){

        getActivity();
    }
}
/*
    获取unity项目的上下文
 */
Activity getActivity(){
    if(null==_unityActivity){
        try{
            Class<?> classtype=Class.forName("com.unity3d.player.UnityPlayer");
            Activity activity=(Activity)classtype.getDeclaredField("currentActivity").get(classtype);
            _unityActivity=activity;
        } catch (ClassNotFoundException e) {
            e.printStackTrace();
        } catch (IllegalAccessException e) {
            e.printStackTrace();
        } catch (NoSuchFieldException e) {
            e.printStackTrace();
        }
    }
    return  _unityActivity;
}
unity端：
AndroidJavaObject activity = new AndroidJavaClass("com.example.mainlibrary.unity").GetStatic<AndroidJavaObject>("_unityActivity");
（包名为com.example.mainlibrary，class名为unity时）
4、使用android端的方法
安卓端：

///获取唯一ID   返回一个String 直接接收使用就可以
public String GetID(){

    String serial = null;

    String m_szDevIDShort = "35" +
            Build.BOARD.length()%10+ Build.BRAND.length()%10 +

            Build.CPU_ABI.length()%10 + Build.DEVICE.length()%10 +

            Build.DISPLAY.length()%10 + Build.HOST.length()%10 +

            Build.ID.length()%10 + Build.MANUFACTURER.length()%10 +

            Build.MODEL.length()%10 + Build.PRODUCT.length()%10 +

            Build.TAGS.length()%10 + Build.TYPE.length()%10 +

            Build.USER.length()%10 ; //13 位
    try {
        serial = android.os.Build.class.getField("SERIAL").get(null).toString();
        //API>=9 使用serial号
        return new UUID(m_szDevIDShort.hashCode(), serial.hashCode()).toString();
    } catch (Exception exception) {
        //serial需要一个初始化
        serial = "serial"; // 随便一个初始化
    }
    return  new UUID(m_szDevIDShort.hashCode(), serial.hashCode()).toString();
    //使用硬件信息拼凑出来的15位号码
}

public static ClipboardManager clipboard = null;

// 向剪贴板中添加文本
public void copyTextToClipboard(final Context activity, final String str) throws Exception {
    clipboard = (ClipboardManager) activity.getSystemService(Activity.CLIPBOARD_SERVICE);
    ClipData textCd = ClipData.newPlainText("data", str);
    clipboard.setPrimaryClip(textCd);
}

unity端：
AndroidJavaObject _ajc;

_ajc = new AndroidJavaObject("com.example.mainlibrary.unity");

 uiText.text += _ajc.Call<string>("GetID");

 _ajc.Call("copyTextToClipboard", activity, input);

5、打包安卓端arr（build->make module）放到unity端的plugins/Android文件夹中

完整代码

    }

     */
