Top 23 Java Android Projects

  • GitHub repo Retrofit

    A type-safe HTTP client for Android and the JVM

    Project mention: What am I missing? Using Volley, trying to import its classes | | 2021-10-22

    Just some advice, would recommend against volley, it's way more of a pain to use than it needs to be. Instead use okhhtp or retrofit if you want a nice abstraction on top of okhhtp.

  • GitHub repo MPAndroidChart

    A powerful 🚀 Android chart view / graph view library, supporting line- bar- pie- radar- bubble- and candlestick charts as well as scaling, panning and animations.

    Project mention: how can i make this chart? xml&java | | 2021-10-15

    There is no easy way of implementing this. You'll have to use a library like MPAndroidChart

  • Nanos

    Run Linux Software Faster and Safer than Linux with Unikernels.

  • GitHub repo Lottie for Android, iOS, and React Native

    Render After Effects animations natively on Android and iOS, Web, and React Native

    Project mention: How is this new Google page made? | | 2021-10-05

    Looks like it's this:

  • GitHub repo glide

    An image loading and caching library for Android focused on smooth scrolling

    Project mention: I made a free fitness app with the most popular Reddit workout programs. Use it to kickstart your fitness journey and end 2021 strong! | | 2021-09-02

    Shortly said, they use React generally with fast-image and Glide for better loading of images Hermes JS Engine for app optimization. The app itself seems to generally use Kotlin and a few Java libraries and they also implemented Sqlite but I'm not sure about the use case for it probably they use it for progress though (The Developer/Marketer needs to confirm this), lastly they seem to use IntellJ Idea for programming and probably compiling

  • GitHub repo ZXing

    ZXing ("Zebra Crossing") barcode scanning library for Java, Android

    Project mention: Mechanical sympathy for QR codes: making NSW check-in better | | 2021-10-12

    Since most government software is written in Java, the QR codes on PDF check-in posters are probably being generated with ZXing [1].


  • GitHub repo jadx

    Dex to Java decompiler

    Project mention: I wrote an open source mod of an Android App | | 2021-10-04

    But before we take a dive into the smali code, let's look at some good ol' Java code. Android byte-code is an optimized form of Java byte-code, which is very easily and reliably decompilable. Don't get me wrong, the result will contain lots of issues and won't be compilable. The tool of choice for Android decompilation is called JADX. Just hand it an apk file and it will produce an entire Android Studio project for you:

  • GitHub repo fastjson

    A fast JSON parser/generator for Java.

    Project mention: Ask HN: Differences in Programming Style by Nationalities | | 2021-04-19

    I first noticed a difference in national styles when I contributed a patch to fastjson, a JSON parser in Java from Alibaba.

    Take a look around the repo; it'll look odd to a western programmer. There is a lot of duplication. And the tests don't have names, they are numbered.

    This was several years ago. I did end up choosing it since it really was the fastest.

  • Scout APM

    Scout APM: A developer's best friend. Try free for 14-days. Scout APM uses tracing logic that ties bottlenecks to source code so you know the exact line of code causing performance issues and can get back to building a great product faster.

  • GitHub repo Exoplayer

    An extensible media player for Android

    Project mention: Would it be possible to get an F-Droid release of the Firewalla app? Or a de-googled version of the app that may be downloaded directly from Firewalla? | | 2021-09-30

    The report from Warden on the loggers are not Loggers in the sense your thinking of (like Analytics ) but Application logging. You have to remember with the functions of the application talking to the firewalla and the device it self having the logs. They had to build a solution to see logs in the Apps and have them Human Readable. They used these to Pretty up the logs they can grab in the app (from a quick repo look at what they do) (

  • GitHub repo material-components-android

    Modular and customizable Material Design UI components for Android

    Project mention: A Comprehensive Guide to Android 12’s Splash Screen API | | 2021-10-13

    It's not released in stable yet. You just take a look at the Material Components for Android github

  • GitHub repo Apktool

    A tool for reverse engineering Android apk files

    Project mention: I wrote an open source mod of an Android App | | 2021-10-04

    The avid reader noticed nothing is human readable, which makes sense as apk files should be as small as possible. A tool called Apktool comes to the rescue.

  • GitHub repo VirtualXposed

    A simple app to use Xposed without root, unlock the bootloader or modify system image, etc.

    Project mention: Using RK Squared with Android 5.1 and FFRK 8.0.0 | | 2021-09-09

    The idea is to try setting up certificate and proxy normally, then install VirtualXposed (you can grab apk from releases), open it, install Japanese version of FFRK inside of VirtualXposed, and at last run the game and see if you can read game traffic. If it works, it could be investigated further if/how this approach could be extended to Global version too. If not - well, it was worth a try.

  • GitHub repo AndroidViewAnimations

    Cute view animation collection.

  • GitHub repo Realm

    Realm is a mobile database: a replacement for SQLite & ORMs

    Project mention: How can I use realm? | | 2021-09-14
