OBB文件不提取错误是＆＃34; XAPK文件验证失败＆＃34;

Question

我成功实现了apk扩展，并在Storage-＆gt; Android-＆gt; Obb-＆gt; PackageName-＆gt; main.1.com.packagename.obb

下载了OBB文件

但是，当我去提取时，我得到的问题是＆＃34;不是Zip档案＆＃34;。

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();
        }

我在2天后得到了解决方案

唯一的问题是 -

.obb文件创建错误的方向

obb文件创建步骤
- 所有资源都存储在一个文件夹中 - 抓住这个文件夹
- 仅将.obb重命名为.zip文件

对此解决方案感到满意
