Question

我想在android中提取zip文件。它适用于其他Zip文件，但我有一个zip文件，无法提取到SD卡的任何路径。它给了我这个错误。

  /storage/emulated/0/AndroidTVAPP/addon_data/plugin.audio.mp3streams/artist_icons/David Bowie.jpg: open failed: ENOENT (No such file or directory)

您需要使用转义字符来确定文件名中是否有空白。

试试这个，

String path = "/storage/emulated/0/AndroidTVAPP/addon_data/plugin.audio.mp3streams/artist_icons/";
String fullPath= path + "David Bowie.jpg";
fullPath = fullPath.replace(" ", "\\ ");

或者您可以使用Uri.parse(path)。

public void unzip(String zipFilePath, String destDirectory) throws IOException {
    ...
    ZipInputStream zipIn = new ZipInputStream(new FileInputStream(Uri.parse(zipFilePath)));
    ...
}

/storage/emulated/0/AndroidAPP/addon_data/plugin.audio.mp3streams/artist_icons/David Bowie.jpg：打开失败：ENOENT（没有这样的文件或目录）
