libgdx robovm binding umeng

我想在libgdx的ios项目中集成友盟统计分析。

友盟目前没有libgdx的插件，so，自己把它搞进来吧。

我们通过robovm binding 在java代码和友盟ios SDK之间搭个桥就可以了。

请看这里：https://github.com/BlueRiverInteractive/robovm-ios-bindings

==========================

1. 首先我们给eclipse（ADT）安装个robovm插件，插件地址：http://download.robovm.org/eclipse/

2. 下载umeng的game分析SDK解压备用

3. 创建RoboVM iOS project：New=》Other=》RoboVM=>RoboVM iOS Project

Next=>

Project name: umeng-binding

Main class: com.tide.binding.umeng.Sample

App name: umeng binding

App id: umengBinding

(以上三信息可在创建后的robovm.properties中修改)

Finish！

4. 创建后的项目中默认只有一个src源文件夹，补上包：com.tide.binding.umeng

5. 创建代码，也就是上面提到的Main class: com.tide.binding.umeng.Sample

代码如下：

package com.tide.binding.umeng;

import org.robovm.apple.foundation.NSAutoreleasePool;
import org.robovm.apple.foundation.NSString;
import org.robovm.apple.uikit.UIApplication;
import org.robovm.apple.uikit.UIApplicationDelegateAdapter;

public class Sample extends UIApplicationDelegateAdapter {
    @Override
    public void didFinishLaunching (UIApplication application) {
        System.out.println("didFinishLaunching");
    }

    public static void main (String[] argv) {
        try (NSAutoreleasePool pool = new NSAutoreleasePool()) {
            UIApplication.main(argv, null, Sample.class);
        }
    }
}

6. umeng game SDK 压缩包解压后共有三个文件

　　libMobClickGameLibrary.a  =>拷贝到项目的libs目录下，没有这个目录新建即可。

　　robovm.xml 中添加这个lib，不然运行时报找不到类

代码如下：

<config>
    <executableName>${app.executable}</executableName>
    <mainClass>${app.mainclass}</mainClass>
    <os>ios</os>
    <arch>thumbv7</arch>
    <resources>
        <resource>
            <directory>resources</directory>
        </resource>
    </resources>
    <target>ios</target>
    <iosInfoPList>Info.plist.xml</iosInfoPList>
    <libs>
        <lib>libs/libMobClickGameLibrary.a</lib>
    </libs>
</config>

　　MobClick.h 稍后我们编写与之对应的binding代码

　　MobClickGameAnalytics.h 稍后我们编写与之对应的binding代码

7. binding MobClick

创建java class MobClick

代码如下：

package com.tide.binding.umeng;

import org.robovm.apple.foundation.NSObject;
import org.robovm.apple.foundation.NSString;
import org.robovm.objc.annotation.Method;
import org.robovm.objc.annotation.NativeClass;
import org.robovm.rt.bro.ValuedEnum;

@NativeClass
public class MobClick extends NSObject  {

    @Method(selector = "setLogEnabled:")
    public static native void setLogEnabled(boolean value);

    @Method(selector = "startWithAppkey:")
    public static native void startWithAppkey(NSString appKey);
}

注意：我只写了两个方法，试了下不报错，所以应该不用对所有方法都绑定(会蛋疼而亡的)。而<UIAlertViewDelegate>的对应实现我也没有写，我不明白为什么友盟的.h文件中写了个这个，不知干嘛用...。

8. 测试一下。

public class Sample extends UIApplicationDelegateAdapter {
    private static final String AppKey = "************";//你的友盟appID
    @Override
    public void didFinishLaunching (UIApplication application) {
        System.out.println("didFinishLaunching");
        NSString a = new NSString(AppKey);
        MobClick.startWithAppkey(a);
        
        MobClick.setLogEnabled(true);
    }

    public static void main (String[] argv) {
        try (NSAutoreleasePool pool = new NSAutoreleasePool()) {
            UIApplication.main(argv, null, Sample.class);
        }
    }
}

项目右键=》Run as =》Ios 模拟器 iphone       第一次编译时间有点长。

稍后可以看到控制台打印：

didFinishLaunching
2014-08-29 17:50:02.767 Sample[1387:4103] Umeng: (Request  Applog) content={"header":{"timezone":"8","sdk_type":"iOS","resolution":"960 x 640","package_name":"umengBinding","sv":"1.0","is_jailbroken":"NO","carrier":"","access":"WiFi","channel":"App Store","os":"iOS","idfv":"565E734A-5170-412B-AF14-786FB272449D","vertical_type":1,"display_name":"umeng binding","os_version":"7.1","device_model":"x86_64","app_version":"1","country":"US","language":"en","sdk_version":"2.3.2.0","appkey":"54003b20fd98c50a1c006ee0","mc":"02:00:00:00:00:00","device_id":"3D99BEEE-7704-4697-AF5B-EEE13887F9E0","is_pirated":"NO"},"body":{"launch":[{"time":"17:50:02","session_id":"9B51DBAB0350C4FD569CE3E7AFFD97A8","date":"2014-08-29"}]}}
2014-08-29 17:50:04.159 Sample[1387:1803] Umeng: (Response Applog) {"success": "ok"}

到umeng的游戏分析中去看，是有数据的。

9. 其他方法绑定及MobClickGameAnalytics....  略

用到哪些再弄吧。

要在libgdx的项目中使用这个binding应该有两种方法，

一是直接搬过去，

二是打包jar使用，类似于robovm-binding项目中的内购那些。

=============================================

补充：2014-09-03

如果是在IDEA+gradle环境下，在执行gradle脚本的时候注意，有一个updateRoboVMXML的命令会被执行到，

可查看ios项目下的build.gradle文件，他会把robovm.xml覆盖掉，所以在这个文件中我们加的libs就没了，运行时就找不到类。

解决办法就是参照他生成的代码，把.a文件扔到他那个build/libs/ios/路径下。
