问题 My Android app (Java 8, min SDK 24, target SDK 27) downloads images from an FTP server, using Apache's FTPClient (version 3.6). There are a couple of smaller .jpg images (around 12kb each) that always download completely but all of the bigger .png images (8+ mb each) show up black in my app. The files on the server look fine, so I downloaded the images from the emulator: Windows' "Photo" app displays a black, horizontal bar at the bottom of all the affected images and they are all missing a

This is my current implementation which generally follows the example provided here: public static FileSystemOptions createDefaultOptions() throws FileSystemException { FileSystemOptions opts = new FileSystemOptions(); SftpFileSystemConfigBuilder.getInstance().setStrictHostKeyChecking( opts, "no");

问题 Background I need to parse some zip files of various types (getting some inner files content for one purpose or another, including getting their names). Some of the files are not reachable via file-path, as Android has Uri to reach them, and as sometimes the zip file is inside another zip file. With the push to use SAF, it's even less possible to use file-path in some cases. For this, we have 2 main ways to handle: ZipFile class and ZipInputStream class. The problem When we have a file-path,
