Updating from Capacitor 4 to Capacitor 5: A Step-by-Step Guide

Compared to previous updates, the transition from Capacitor 4 to Capacitor 5 involves minimal breaking changes. This guide provides step-by-step instructions for updating your project to Capacitor 5, as well as a list of breaking changes for official plugins.

Note: Capacitor 5 requires NodeJS 16 or higher, as Node 12 has reached end-of-life and Node 14 will reach end-of-life on April 30th, 2023. It is recommended to use the latest LTS version of NodeJS.

Install the latest version of the Capacitor CLI in your project:
```
npm i -D @capacitor/cli@latest
```
Run the following command to let the CLI handle the migration:
```
npx cap migrate
```
If any migration steps cannot be achieved, additional information will be provided in the terminal output. Manual migration steps are listed below.
If you have the VS Code extension installed, check the recommendations section of the extension to find the option to migrate your project to Capacitor 5.

Upgrading Capacitor 4 iOS Project to Capacitor 5

Upgrade Xcode: Capacitor 5 requires Xcode 14.1+.
Update .gitignore: Make the following changes to your .gitignore file:
```
- App/Podfile.lock
+ App/output
```
Update Assets to use a single app icon: Xcode 14 supports a single app icon of 1024x1024. Clean up your AppIcon.appiconset by removing all unnecessary sizes.

Upgrading Capacitor 4 Android Project to Capacitor 5

Upgrade Android Studio: Capacitor 5 requires Android Studio Flamingo | 2022.2.1 or newer due to the usage of Gradle 8, which requires Java JDK 17. Java 17 ships with Android Studio Flamingo, so no additional downloads are needed.
Run AGP Upgrade Assistant: Android Studio can help with some updates related to Gradle and moving packages into build files. To start, run Tools -> AGP Upgrade Assistant.

Update Android Project Variables: In your variables.gradle file, update your values to the following new minimums:

minSdkVersion = 22
compileSdkVersion = 33
targetSdkVersion = 33
androidxActivityVersion = '1.7.0'
androidxAppCompatVersion = '1.6.1'
androidxCoordinatorLayoutVersion = '1.2.0'
androidxCoreVersion = '1.10.0'
androidxFragmentVersion = '1.5.6'
coreSplashScreenVersion = '1.0.0'
androidxWebkitVersion = '1.6.1'
junitVersion = '4.13.2'
androidxJunitVersion = '1.1.5'
androidxEspressoCoreVersion = '3.5.1'
cordovaAndroidVersion = '10.1.1'

Update Google Services:

# build.gradle
dependencies {
-       classpath 'com.google.gms:google-services:4.3.13'
+       classpath 'com.google.gms:google-services:4.3.15'
}

Update Gradle plugin to 8.0.0:

# build.gradle
dependencies {
-       classpath 'com.android.tools.build:gradle:7.2.1'
+       classpath 'com.android.tools.build:gradle:8.0.0'
}

Update Gradle wrapper to 8.0.2:

# gradle-wrapper.properties
distributionBase=GRADLE_USER_HOME
distributionPath=wrapper/dists
- distributionUrl=https\://services.gradle.org/distributions/gradle-7.4.2-all.zip
+ distributionUrl=https\://services.gradle.org/distributions/gradle-8.0.2-all.zip
zipStoreBase=GRADLE_USER_HOME
zipStorePath=wrapper/dists

Disable Jetifier:

# gradle.properties
android.useAndroidX=true
- android.enableJetifier=true

Move package to build.gradle:

# AndroidManifest.xml
<?xml version="1.0" encoding="utf-8"?>
- <manifest xmlns:android="http://schemas.android.com/apk/res/android"
-     package="[YOUR_PACKAGE_ID]">
+ <manifest xmlns:android="http://schemas.android.com/apk/res/android">

# build.gradle
android {
+     namespace "[YOUR_PACKAGE_ID]"
      compileSdkVersion rootProject.ext.compileSdkVersion

Update androidScheme: In Capacitor 6, https will be the default setting for androidScheme for existing apps to better enable Capacitor applications to use the system Autofill feature. To avoid data loss as a result of this change, set the scheme to http now, even if it’s the current default.
```
{
  server: {
    androidScheme: "http"
  }
}
```
Update Kotlin version: If your project uses Kotlin, update the kotlin_version variable to '1.8.20'.
