    Image Picker Library for Android

    Image Picker Library for Android

    Image Picker for Android, Pick an image from Gallery

    Easy to use and configurable library to Pick an image from the Gallery or Capture an image using a Camera. It also allows to Crop and Compress the Image based on Aspect Ratio, Resolution, and Image Size. Almost 90% of the apps that I have developed have an Image upload feature. Along with the image selection, Sometimes I needed a crop feature for my profile image for that I've used uCrop. Most of the time I need to compress the image as the image captured from the camera is more than 5-10 MBs and sometimes we have a requirement to upload images with specific resolution/size, in that case, image compression is the way to go option. To simplify the image pick/capture option I have created the ImagePicker library. I hope it will be useful to all.

    LibrePods

    LibrePods

    AirPods liberated from Apple's ecosystem

    LibrePods is an open-source project that brings many AirPods features normally limited to Apple devices onto Android and Linux.

Some advanced functions require root access or VendorID spoofing, depending on the device and OS version. Linux support covers core controls, while newer functionality remains under active development. The project also experiments with multipoint connectivity and higher-quality microphone workflows while documenting platform limitations clearly.

    Kitsunebi

    Kitsunebi

    A fully-featured V2Ray client for Android

    A fully-featured V2Ray client for Android. The Core used by Kitsunebi extends the function of v2ray-core, and adds a strategy of selecting the fastest node according to the node delay value. You can add a node group on the graphical interface to enable it. If you use custom configuration, there are several configuration items, except for tolerance. The delay test is not ICMP Ping or TCP Ping, the method used is roughly the same as that used by the latency strategy in load balancing, actually sends a proxy request to outbound, and records the time it takes to return non-null data. The delay test is also equivalent to the availability or connectivity test. As long as the delay can be measured, it means that the node is available. If it cannot be measured or times out, the availability is unknown.

    SurvivalManual

    Libre Survival Manual for Android with offline in mind

    This is a survival manual/guide based on the public domain US Army Survival Field Manual FM 3-05.70 (FM 21-76). It is fully functional offline, which is important in the case of a catastrophe. But it doesn't have to be used only in emergency situations, it can also be useful for outdoor trips, walks, camps, and learning about nature and yourself truly. This is not only fun, but you can also train skills (fire, build shelter, ...) that you may need in a catastrophe. Some things work best with practice in a relaxed environment, so you also have time for some experiments. The refugees also are welcome to use this application to prepare and guide you for your dangerous journey. Although I hope that we as humans will come to feel and stop wars and end climate injustice so that people do not have to flee and be afraid.

Platform Protocol Tunnel License What It Does Many ISPs throttle or block VPN traffic using Deep Packet Inspection (DPI). Warp-over-WebSocket-CDN wraps WireGuard UDP inside a WebSocket connection with a spoofed Host header, routing traffic through major CDN edge networks (CloudFront, Cloudflare, or Akamai). To any firewall or DPI system, the traffic looks like a legitimate WebSocket upgrade to a CDN-hosted domain. Result: Full Cloudflare Warp speed and privacy, even on heavily restricted networks — including campus, corporate, and ISP-level DPI systems.
