Publishing your Ionic app

Building release version from macOS

Build the APK

First of all we need to build the APK.

ionic build --release android

Generate private Key

Then we will create a keystore to sign the APK. keytool -genkey -v -keystore my-release-key.keystore -alias alias_name -keyalg RSA -keysize 2048 -validity 10000

• Change my-release-key with your key name.
• Change alias_name with your key alias.

Sign the APK

jarsigner -verbose -sigalg SHA1withRSA -digestalg SHA1 -keystore my-release-key.keystore HelloWorld-release-unsigned.apk alias_name

• Change my-release-key with your key name.
• Change HelloWorld-release-unsigned with your unsigned apk. ionic-project/platforms/android/build/outputs/apk.
• Change alias_name with your key alias.

Zip the APK

zipalign -v 4 HelloWorld-release-unsigned.apk HelloWorld.apk

• You can find zipalign in /Users/username/Library/Android/sdk/build-tools/XXX/
• Change HelloWorld-release-unsigned with your unsigned apk. ionic-project/platforms/android/build/outputs/apk.
• Change HelloWorld.apk with your prefered apk file name. This will be uploaded to Google Play.
