问题描述

我实现APK扩展成功和OBB文件的存储 - > Android-> Obb-> PackageName-> main.1.com.packagename.obb

但是,当我去解我得到的问题是没有一个Zip压缩文件。

子presourceFile ZRF =新的子presourceFile(文件名);

 公共子presourceFile(字符串zipFileName)抛出IOException异常{
        addPatchFile(zipFileName);
    }

    无效addPatchFile(字符串zipFileName)抛出IOException异常{
        档案文件=新的文件(zipFileName);
        RandomAccessFile的F =新RandomAccessFile的(文件,R);
        长文件长度= f.length();

        如果(文件长度< kEOCDLen){
            抛出新的java.io.IOException异常();
        }

        长readAmount = kMaxEOCDSearch;
        如果(readAmount>文件长度)
            readAmount =文件长度;

        / *
         *确认这是一个ZIP文件。
         * /
        f.seek(0);

        INT标题= read4LE(F);
        如果(标题== kEOCDSignature){
            Log.i(LOG_TAG,发现Zip文件,但它看起来空);
            抛出新IOException异常();
        }否则,如果(头!= kLFHSignature){
            Log.v(LOG_TAG,不是一个Zip压缩文件);
            抛出新IOException异常();
        }

解决方案

我得到了2天后的解决方案

唯一的问题是 -

.obb文件是创建错误的方向

在OBB文件中创建步骤
- 所有资源存储在一个文件夹中。
-Zip这个文件夹
- 仅重命名.obb为.zip文件

快乐与此解决方案

I implemented apk expansion successfully and OBB file downloaded at Storage->Android->Obb->PackageName->main.1.com.packagename.obb

But when i go to extract i am getting issue is "Not a Zip archive".

ZipResourceFile zrf = new ZipResourceFile(fileName);

public ZipResourceFile(String zipFileName) throws IOException {
        addPatchFile(zipFileName);
    }

    void addPatchFile(String zipFileName) throws IOException {
        File file = new File(zipFileName);
        RandomAccessFile f = new RandomAccessFile(file, "r");
        long fileLength = f.length();

        if (fileLength < kEOCDLen) {
            throw new java.io.IOException();
        }

        long readAmount = kMaxEOCDSearch;
        if (readAmount > fileLength)
            readAmount = fileLength;

        /*
         * Make sure this is a Zip archive.
         */
        f.seek(0);

        int header = read4LE(f);
        if (header == kEOCDSignature) {
            Log.i(LOG_TAG, "Found Zip archive, but it looks empty");
            throw new IOException();
        } else if (header != kLFHSignature) {
            Log.v(LOG_TAG, "Not a Zip archive");
            throw new IOException();
        }

解决方案
