Problem to generate Splash and icon

Hi guys, i’m trying to add splash and icons into in my ionic 2 project, i’ve added the params in the config.xml
<preference name="FadeSplashScreenDuration" value="300"/> <preference name="SplashMaintainAspectRatio" value="true"/> <preference name="SplashScreenDelay" value="1500"/> <preference name="SplashScreen" value="screen"/>

and i’ve added the cordova plugin splashscreen
<plugin name="cordova-plugin-splashscreen" spec="~3.2.2"/>

but when i try build the apk, my app are still showing the cordova splash, even i run ionic resources
