我正在尝试借助此代码以编程方式在我的应用程序中解压缩.zip

public void unzip(String _zipFile, String _targetLocation) {

    dirChecker(_targetLocation);

    try {
        FileInputStream fin = new FileInputStream(_zipFile);
        ZipInputStream zin = new ZipInputStream(fin);
        ZipEntry ze = null;

        while ((ze = zin.getNextEntry()) != null) {
            if (ze.isDirectory()) {
                dirChecker(ze.getName());
            } else {
                FileOutputStream fout = new FileOutputStream(_targetLocation + ze.getName());
                for (int c = zin.read(); c != -1; c = zin.read()) {
                    fout.write(c);
                }

                zin.closeEntry();
                fout.close();
            }
        }
        zin.close();

        Log.i("xoxo", "unzip: completed!!!");
    } catch (Exception e) {
        Log.i("xoxo", "unzip: err: - " + e.toString());
    }
}

一切都很好,但是问题是我遇到了错误,

java.util.zip.ZipException: only DEFLATED entries can have EXT descriptor

在尝试解压缩在Linux环境上运行的服务器创建的.zip时。

如何解决此错误?

您可以尝试此库 https://github.com/ankitdubey021/ExtractionLib

void extract(){

try {
    File outputFile = new File(Environment.getExternalStoragePublicDirectory(Environment.DIRECTORY_DOCUMENTS), "value1.jar");
    Extract.extract(outputFile, new File(Environment.getExternalStoragePublicDirectory(Environment.DIRECTORY_DOCUMENTS), "extration").toString());

    Toast.makeText(MainActivity.this, "Extracted!", Toast.LENGTH_SHORT).show();
}catch(Exception e){
    System.out.println(e);
}}

它将轻松提取您的zip文件。 3年前,我在一个项目中使用了它。仍在工作。
