I can't add the image-picker plugin in my application

I am trying to add this plugin to my project
I ran these 2 commands

1- ionic cordova plugin add cordova-plugin-telerik-imagepicker --variable PHOTO_LIBRARY_USAGE_DESCRIPTION="your usage message"
2- npm install --save @ionic-native/image-picker
and then added the plugin to my app’s module

when running the app on ionic devApp , it makes this error

Uncaught (in promise): plugin_not_installed

my info

Ionic Framework: 3.9.2
Ionic App Scripts: 3.1.6
Angular Core: 5.0.3
Angular Compiler CLI: 5.0.3
Node: 8.9.1
OS Platform: macOS High Sierra
Navigator Platform: MacIntel
User Agent: Mozilla/5.0 (Linux; Android 6.0; Nexus 5 Build/MRA58N) AppleWebKit/537.36 (KHTML, like Gecko) Chrome/63.0.3239.132 Mobile Safari/537.36

note : when I try to remove the plugin using this command
ionic cordova plugin rm cordova-plugin-telerik-imagepicker

it makes this strange error :

Error: Plugin “cordova-plugin-telerik-imagepicker” is not present in the project. See cordova plugin list.

when I run “ionic cordova plugin ls” , I got this

com.synconset.imagepicker 2.1.8 "ImagePicker"
cordova-plugin-device 1.1.4 "Device"
cordova-plugin-image-picker 1.1.1 "ImagePicker"
cordova-plugin-ionic-webview 1.1.16 "cordova-plugin-ionic-webview"
cordova-plugin-splashscreen 4.0.3 "Splashscreen"
cordova-plugin-whitelist 1.3.1 "Whitelist"
cordova-sqlite-storage 2.2.0 "Cordova sqlite storage plugin"
ionic-plugin-keyboard 2.2.1 “Keyboard”

so - where’s the issue ?

add your plugin again and test your app on android device instead of ionic devapp …it will work …there is isssue with ionic-dev app and plugin

ionic devApp is android app and works on actually android device
do you mean build the application separably and test it alone?

yes using ionic cordova build android…instead of ionic serve command generate apk file

Okey - I’ll have to download the Android SDK and the required tools to build it

yes best luck…
