This is a step by step on how to build a release apk file. And then we can run this apk on our android device : )

Before we start open a terminal (command line) and navigate into you app folder (cd myappfolder)

Step 1 : we add the android platform

ionic platform add android

Step 2 : go to platforms folder and then to android folder

cd platforms/android

Step 3 : we generate a file

keytool -genkey -v -keystore <strong>angular2ionic2.keystore</strong> -alias <strong>angular2ionic2</strong> -keyalg RSA -keysize 2048 -validity 10000

Once you finish the questions you will find a file like: angular2ionic2.keystore

You will enter a password during the generation of angular2ionic2.keystore you need to remember this password and keep your angular2ionic2.keystore in a safe place.

Step 4:  open the file build.gradle in the current directory platforms\android

We will tell gradle about the keystore.

Search the android section in this file it looks like :

android {



Then search the section (signingConfigs) under android {} and add the code :

signingConfigs {

release {
storeFile file("angular2ionic2.keystore")
storePassword 'YourPassword'
keyAlias 'angular2ionic2'
keyPassword 'YourPassword'


Step 5: run the build command

Back to your root folder and run this command.

ionic build android --release

Wait until the build is successfully accomplished, it will generate this file :


And then we sign it.

Step 5 : sign the apk file.

jarsigner -verbose -sigalg SHA1withRSA -digestalg SHA1 -keystore <strong>angular2ionic2.keystore</strong> <strong>android-release-unsigned.apk</strong> angular2ionic2


Hint: for security reasons don’t store the file angular2ionic2.keystore (YourApp.keystore) under work project.

The app is ready to be installed under your Android devices.
