Galio is a UI toolkit and component framework for React Native that provides a consistent set of ready-made, themeable building blocks (buttons, cards, text, inputs, nav bars, etc.) so you can prototype and ship mobile UIs faster. The galio repository includes the core components and a lightweight theme system in src/theme (see colors.tsx, sizes.tsx, index.tsx) plus components under src/ such as Block, Button, Text, Input, Card, Avatar, NavBar and more.

This short guide helps you make React Native apps run smoother on older Android phones (API 21–28) by applying practical, beginner-friendly optimizations. Follow the steps to enable Hermes, shrink and harden your APK with ProGuard, optimize list and image rendering, and deploy fixes quickly with EAS OTA updates so users on low-end devices get a noticeably better experience.

React Native has become one of the most popular frameworks for building cross-platform mobile applications. If you’re a Windows user looking to start your React Native development journey, this comprehensive guide will walk you through every step of the installation process.

React Native developers are often in the situation of releasing their React Native apps to the Google Play Store so that Android users can download them. In this tutorial, we are going to learn how to generate a React Native Release Build APK for Android, using both React Native CLI and Android Studio IDE. At Instamobile, we launched all of our React Native Templates to production (Google Play Store demos), so we are familiar with the process as well as the errors that might show up when generating a React Native Release Build APK for Android. We are documenting our learnings in this React Native tutorial, to help mobile developers ship their Android apps to production more quickly.
