and after using this plug in when i go and build then getting this error
and in menifest file its reproducing the error like this
Menifest file before ionic cordova build android looks like
<?xml version='1.0' encoding='utf-8'?>
<manifest android:hardwareAccelerated="true" android:versionCode="1" android:versionName="0.0.1" package="io.ionic.starter" xmlns:android="http://schemas.android.com/apk/res/android">
