I want to reinstall image picker plugin when I remove it using the command
ionic cordova plugin rm cordova-plugin-telerik-imagepicker --save
it removes from package json but not remove from platform android
use cordova clean and and check again
thnx for reply but I get the same issue 
use following command :-
cordova plugin remove <PLUGIN_NAME>
cordova plugin list for know name of plugin
cordova plugin remove 'nameOfPlugin' for remove plugin(without the Apostrophe)
thnx for replay I use this command also this remove plugin but not install plugin which added in platform folder
in package.json remove the plugin which you want to, and execute the command “npm install” on main project folder
