Ionic 2/Ionic 3 - Adding Cordova Android Platform

In previous tutorial we created our first Ionic 2/3 project .Ionic apps are cross platform which mean they can be used to target Android ,iOS and Windows phone (UWP) devices but before you can actually target a specific device platform you need to add the platform to your Ionic project so lets cover how to do that for Android .

First ,before you can add an Android platform to your Ionic 2/3 project you need to have some requirements installed on your development machine :

First install Java on your system if its not installed

You can verify if Java installed on your system by running

java -v 

If the command goes unrecognized then head over to Java official website and download Java then install it .

Setup JAVA_HOME environment variable to point to your Java installation folder .

export JAVA_HOME='path/to/java'

Next install the Android SDK from Android studio official website (You can install the whole Android studio or just the Android SDK)

Setup the ANDROID_HOME environment variable to point tou your SDK folder .

export ANDROID_HOME='/path/to/android/sdk'

Finally you need to install Cordova if it's not yet installed .

npm install -g cordova

These are all the requirements you need to have before you can add an Android platform to your project .

Now lets add an android platform to our project .

Navigate to our previously created project then run

ionic platform add android (If using Ionic CLI < v3)

Or

ionic cordova platform add android (If using Ionic CLI >= v3 )

That's it you have now added an android platform to your project which means you can build and run your app on Android devices

ionic run android -l 

This command will run your app in your Android device with live reload enabled which means every time you make changes to your source code it gets reloaed on the device and the app will be refreshed / restarted which is a nice feature if you are developing and testing your app in a real device .

Conclusion


We have covered how to add an Android platform to Ionic 2/3 projects and all the requirements we need to have installed before we can do that .
