v2rayNG
A V2Ray client for Android, support Xray core and v2fly core
A V2Ray client for Android supports Xray core and v2fly core. geoip.dat and geosite.dat files are in Android/data/com.v2ray.ang/files/assets (path may differ on some Android devices). Download feature will get an enhanced version in this repo (Note it need a working proxy). The latest official domain list and ip list can be imported manually. It's possible to use third-party dat files in the same folder, like h2y. Android projects under V2rayNG folder can be compiled directly in Android Studio or using Gradle wrapper. But the v2ray core inside the aar is (probably) outdated. The aar can be compiled from the Golang project under AndroidLibV2rayLite folder. v2rayNG can run on Android Emulators. But VPN mode will not work if the system doesn't support it. -

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. -

SagerNet
The universal proxy toolchain for Android
The universal proxy toolchain for Android, written in Kotlin. To use hysteria plugin with version smaller than 1.2.1, the highest compatible version of SagerNet is 0.8.1-rc02. The new protocol is designed to improve UDP performance and provide full replay protection. Using an MTU larger than the upstream interface will only improve speed in some scenarios and may result in UDP packet loss. According to the gfw.report et al's research, when connecting to the impacted VPSs, GFW is likely to block binary protocols unless it is an HTTP, TLS, or SSH connection, or the first 6 bytes of data sent from client to server can be interpreted as printable characters. This suggests in addition to TLS encryption, HTTP Header, this kind of censorship can also be temporarily evaded by only sending printable characters in the first 6 bytes of data. -

Ruler
Gradle plugin which helps you analyze the size of your Android apps
App size is an important metric which directly correlates with business metrics like install conversion rate. Measuring app size is straightforward, but knowing what contributes to it is not. Especially in bigger projects with hundreds or thousands of modules and third-party dependencies. Ruler provides a convenient way to find out how much each module and dependency contributes to the total size of your app by running a single Gradle task. First you need to add the Ruler Gradle plugin to the buildscript classpath in your top-level build.gradle file. When using app bundles, Google Play will generate optimized APKs for each device. This means that the size of an APK depends on the specifications of the device that's downloading it. You can configure which device specifications should be used for the analysis in the build.gradle of your application module. -

Elixir plugin for JetBrain's IntelliJ
Elixir plugin for JetBrain's IntelliJ Platform (including Rubymine)
The plugin works both in the rich IDEs that allow alternative language SDK selection and small IDEs that are language specific. The rich IDEs work best for IntelliJ Elixir because only in the rich IDEs can have an Elixir SDK set as the Project SDK. In all small IDEs, the native language SDK is always there, which makes anything that uses the SDK, such as running elixir, erl, or mix more complicated both internally and externally in the configuration you have to setup. The plugin will automatically find the newest version of Elixir installed. (NOTE: SDK detection only works for Linux, homebrew installs on OSX, and Windows. Open an issue with information about Elixir install locations on your operating system and package manager to have SDK detection added for it.) If the automatic detection doesn't find your Elixir SDK or you want to use an older version, manually select select the directory above the bin directory. -

Gradle Play Publisher
GPP is Android's unofficial release automation Gradle Plugin
Gradle Play Publisher (GPP) is Android's unofficial release automation Gradle Plugin. It can do anything from building, uploading, and then promoting your App Bundle or APK to publishing app listings and other metadata. The first APK or App Bundle needs to be uploaded via the Google Play Console because registering the app with the Play Store cannot be done using the Play Developer API. For all subsequent uploads and changes, GPP may be used. To successfully upload apps to the Play Store, they must be signed with your developer key. Make sure you have a valid signing configuration. After you've gone through the Service Account setup, you should have a JSON file with your private key. GPP supports uploading both the App Bundle and APK. Once uploaded, GPP also supports promoting those artifacts to different tracks. -
