🚀 How to Build & Export an Android APK in React Native (Step-by-Step Guide!) 📱🔥

Описание: Hey everyone! In this guide, I'll walk you through how I create an APK for my React Native apps. Whether you're preparing for testing or publishing on the Play Store, follow these steps to get your APK ready. Let's dive in!

1️⃣ Set Up Your Environment
Before building the APK, ensure you have everything installed:
✅ Node.js & npm/yarn – The foundation for React Native
✅ React Native CLI – If using the CLI version, install it via:

npm install -g react-native-cli

✅ Android Studio – Needed for the Android SDK & emulator
✅ Java Development Kit (JDK) – Java 17+ is recommended

2️⃣ Generate a Signed APK
If you’re planning to release your app, you'll need a signed APK. Here’s how I do it:

🔹 Create a Keystore File
Run this command to generate a keystore:
keytool -genkeypair -v -keystore my-release-key.jks -keyalg RSA -keysize 2048 -validity 10000 -alias my-key-alias

Save this file inside android/app.

🔹 Add Keystore to Gradle
Edit android/gradle.properties and add:

MYAPP_RELEASE_STORE_FILE=my-release-key.jks
MYAPP_RELEASE_KEY_ALIAS=my-key-alias
MYAPP_RELEASE_STORE_PASSWORD=your-password
MYAPP_RELEASE_KEY_PASSWORD=your-password

🔹 Update android/app/build.gradle
Find signingConfigs and modify it to use your keystore details:

signingConfigs {
release {
storeFile file(MYAPP_RELEASE_STORE_FILE)
storePassword MYAPP_RELEASE_STORE_PASSWORD
keyAlias MYAPP_RELEASE_KEY_ALIAS
keyPassword MYAPP_RELEASE_KEY_PASSWORD
}
}
Using CMD

Build the APK
Now, let's generate the APK! Run this command:
cd android && ./gradlew assembleRelease

After completion, you’ll find the APK inside:
android/app/build/outputs/apk/release/
