About

QRServ is a file sharing application that utilises its own HTTP server to serve files while having a clean & functional user interface.

Features

  • Tap on the QR code to show full URL in a tooltip
  • Press and hold on the QR code to copy full URL to clipboard
• Share / Copy to clipboard option
• Multi-file selection support (Android only)
  • Multi-file selection would result in a ZIP archive
    • Tooltip when press and holding on the resulting archive file name will reveal the originally selected files
• Direct Access Mode (Android only)
  • Only available on Android 10 or earlier on the Play Store version
  • To use this feature on Android 11 or later, use the GitHub version (link is in-app under the 'about' dialog) -- please note that the Play Store version needs to be uninstalled first as it would be signed using a different certificate
  • Large files? Use direct access mode to use direct access to internal storage as to avoid attempting to copy the selection into app cache
  • The file manager for this mode only supports single file selection
  • The mode can be toggled by pressing on the SD card icon

Releases

Android builds can be found in the releases section of this repository.

Note: Android builds on GitHub will have a different certificate than builds on the Play Store. In other words, you cannot upgrade a build from installation source A via source B and vice versa.

Play Store and GitHub version differences

As you may be aware, there are two different Android builds of this application. This section will cover the differences.

Play Store

• Direct Access Mode is not available for Android 11 or later due to the MANAGE_EXTERNAL_STORAGE runtime permission requirement (see issue #20)
  • In short, Google Play had became far more strict about the usage of such sensitive permission since June 2024
  • There hasn't been much luck in terms of using the MediaStore API.. at least from existing Flutter packages that kind of act like a wrapper (typically, there's issues and limitations) -- it would likely be the case of writing that functionality from scratch using Kotlin

GitHub

• Direct Access Mode is available for all supported Android versions, as MANAGE_EXTERNAL_STORAGE can be used to allow support for Android 11 or later

Changing build types

By default, the source code builds to the GitHub version. The build type can be changed through the filemanager.dart file in the isPlayStoreFriendly section (instructions can also be found there). Update the permissions under AndroidManifest.xml as appropriate.

Desktop

Last desktop builds (Windows, Linux) can be found in the releases section under v1.1.1.

Contributing

Before creating a new issue or putting together a pull request (particularly regarding feature requests or potential improvements), please refer to the design philosophy. It also serves as a Q&A.

Building

Android

If you wish to have debugging symbols for an app bundle release, ensure you have the Android NDK installed. You may need to specify the ndk.dir in the local.properties file.
However, if you do not plan to do a Play Store release, you may remove the ndk block from android.defaultConfig in the gradle build file.

Windows

Windows builds normally require Visual C++ Redistributable for Visual Studio 2015 to run. There are two ways you could go about it:

1. Install Visual C++ Redistributable for Visual Studio 2015
2. Bundle the required files in the root directory of the compiled executable (msvcp140.dll, vcruntime140.dll, vcruntime140_1.dll) -- ideal when distributing

You could package builds as a MSIX but that is only practical if you plan to get or already have a code signing certificate.
