android/NDK开发assets资源中文名打包问题

项目是C开发的能在android跑了，最近想把项目打包上传googleplay碰到一个问题资源图片没办法打包，原先我的图片资源都是直接拷贝到SDcard一个文件夹下的，C代码层直接访问SDcard的资源图片就OK了，安装过程好麻烦图片资源要手动拷贝到sdcard上。
这问题纠结了好久
本想把资源放到res目录下的，但是资源有图片 ini配置档之类的文件C代码层访问这个目录也是问题。
放到这个assets文件呢? 测试过这个目录不支持中文名字，由于项目的资源都是中文命名的，改成英文工作量大也影响其他人的修改。
后来发现把资源压缩成zip能放到assets目录下，太高兴了问题能解决了。
解决方案：
把资源打包成zip 放入assets目录下，当程序启动的时候把zip解压到sdcard目录下，这样C层代码能直接访问sdcard下的资源包了。

解压的代码:

Test.java: //判断资源是否需要安装，需要跳转到安装页面public class Test extends Activity {    super.onCreate(savedInstanceState);        JmpPage();}private void JmpPage(){        String path = android.os.Environment.getExternalStorageDirectory() + "/Test";        String ZipPath = android.os.Environment.getExternalStorageDirectory() + "/Test.zip";                 long length = 28;//Test 文件大小 设置比原文件夹小       //判断是否有SDcard        if(android.os.Environment.getExternalStorageState().equals(android.os.Environment.MEDIA_MOUNTED)){       File file = new File(path);       long FileSize = 0;              if(file.exists())       {         FileSize = GetFileSize(new File(path))/(1024*1024); //获取SDcard剩余容量         Log.v("Test","FileSize:"+FileSize);       }              file = new File(ZipPath);//删除zip       if(file.exists()){       file.delete();       }       if(FileSize < length){//如果资源包小于37M数据包不完整       if(GetAvailableSdcard() > (length+4))//sdcard内存需要大于39M才可以安装资源       {         Intent intent = new Intent(Test.this, InstallActivity.class); //跳转到解压页面                  intent.setFlags(Intent.FLAG_ACTIVITY_CLEAR_TOP);                   startActivity(intent);       }       else       {       Toast.makeText(Test.this, "sdcard容量满了,请删除一些!", 1).show();       }       }       Log.v("Test","FileSize > length");       }       else{              Toast.makeText(Test.this, "未找到sdcard无法安装程序!", 1).show();       }} private long GetAvailableSdcard(){android.os.Environment.getExternalStorageDirectory();StatFs statFs = new StatFs(android.os.Environment.getExternalStorageDirectory().toString());       // 获取block的SIZE       long BlockSize = statFs.getBlockSize();       // 可使用的Block的数量       long AvailaBlock = statFs.getAvailableBlocks();       long AvailableSize = AvailaBlock * BlockSize;       return AvailableSize;}//获取文件夹大小private long GetFileSize(File file){long result = 0;

这有个很严重问题apk会很大，而且apk卸载了sdcard中的文件不会自动删除希望各位同仁提供方法。
上面代码有部分参考其他人的，本人一直玩C刚学java不久，相信也有人遇到同样的问题拿出来分享一下，如果有更好的方法希望可以交流交流。
