ios

Had to run this first:

$ sudo xcode-select -s /Applications/Xcode.app/Contents/Developer

Then in Ionic project, this should work:

$ ionic cordova emulate ios

Android

(to check platform versions: $ cordova platform ls )

(in onpoint):

$ ionic cordova platform update android or $ ionic platform update android@6.2.3

$ ionic cordova build android

For fresh install of latest version of Android Studio (v2.2.3):

To avoid a range of Android SDK errors (e.g. gradle wrapper, license, versions, etc) when running $ ionic cordova emulate android, I did the following:

• After standard install, open Anroid Studio —> * Configure menu —> SDK Manager —> Just to be safe, I installed both O and Nougat SDK Platforms.

• Might also need to update JDK to 8.0, got dmg here: http://www.oracle.com/technetwork/java/javase/downloads/jdk8-downloads-2133151.html

• (this resolved gradle wrapper issue) apparently templates directory in ~/Library/Android/sdk/tools was missing, so I downloaded the Android SDK tools package and just copied the entire templates directory from tools into the tools that was already installed at ~/Library/Android/sdk/tools

• a JS error was happening emanating from emulator.js in onpoint/platforms/android/cordova/lib on line 202 which I was able to silence by commenting out:

  var num = target.split('(API level ')[1].replace(')', '');

and replacing with:

var num = target.match(/\d+/)[0];

NOW, in order to run the emulator, you have to actually start a virtual device in Android Studio first:

1. Create a project.
2. Open project and click AVD Manager button inside project to open virtual device manager.
3. Select or Add a virtual device manager and click on green arrow in Actions to start virtual device.

Next, back over to Ionic project:

$ ionic cordova emulate android

for removing current Android SDK install:
