Following is the screenshot of packages installed in Android SDK Manager:

Also this is the informations of my ionic system:

#->ionic info

Your system information:

Cordova CLI: 4.3.1
Ionic Version: 2.0.0-beta.1
Ionic CLI Version: 2.0.0-beta.17
Ionic App Lib Version: 2.0.0-beta.8
ios-deploy version: Not installed
ios-sim version: Not installed
OS: Mac OS X El Capitan
Node Version: v5.3.0
Xcode version: Not installed


******************************************************
 Dependency warning - for the CLI to run correctly,      
 it is highly suggested to install/upgrade the following:     

 Install ios-sim to deploy iOS applications. `npm install -g ios-sim` (may require sudo)
 Install ios-deploy to deploy iOS applications to devices. `npm install -g ios-deploy` (may require sudo)

******************************************************

I just want to run on android device right now, so ios-sim and ios-deploy packages are not installed.

Update When I try to run to add platform android, it saying already exist:

#->ionic  platform add android
Running command: /Users/Piccaza/ionic-projects/fobs-v0.9.9/hooks/before_platform_add/init_directories.js /Users/Piccaza/ionic-projects/fobs-v0.9.9
Platform android already added.

what might be the issue here, so that I am not able to run the app on device? I am kind of stuck for 2 days please help out.

回答1:

Instead of just ionic run android I tried with sudo, as follows:

sudo ionic run android

And app started running in device.

NOTE: ionic wont show any error or waring if we just execute the command: ionic run android
