# Building App on device

## Build the app for Android

{% embed url="<https://www.youtube.com/watch?v=6MRrep69cEM>" %}

Once you have modified your app as per your requirements, you can start building the app for Android. Add an android platform to the project by running

```
$ ionic cordova platform add android
```

This step will add an android platform to the project.&#x20;

{% hint style="info" %}
Previous step will require [Android Studio](https://developer.android.com/studio) preinstalled on your system. You can also install Android SDK without Android Studio, but that is not the recommended way.
{% endhint %}

Now prepare the platform for a build

```
$ ionic cordova prepare android
```

And run the app on your device or simulator by running

```
$ ionic cordova run android
```

An iOS app can be built only on an Apple based system. Add an iOS platform to the project by running

```
$ ionic cordova platform add iOS
```

This step will add an iOS platform to the project.&#x20;

{% hint style="info" %}
Previous step will require [Xcode](https://itunes.apple.com/in/app/xcode/id497799835?mt=12) preinstalled on your system. You will also need an Apple developer license and proper provisioning profiles to build the app on device.
{% endhint %}

Now prepare the platform for a build

```
$ ionic cordova prepare ios
```

And run the app on your device or simulator by running

```
$ ionic cordova run ios
```

OR, run the app using **XCode** directly.
