Element uses-permission#android.permission.CAMERA duplicated with element declared at AndroidManifest.xml
As it is very clear from the Error message that two elements i.e. plugins are using same permission. To resolve such issue you can do the following:
Comment out/remove the line of
uses-permission
anduses-feature
in ...\plugins\phonegap-plugin-barcodescanner\plugin.xml<uses-permission android:name="android.permission.CAMERA"/><uses-feature android:name="android.hardware.camera">
rm platform android
add platform android
ionic cordova run android
No need to touch AndroidManifest.xml
file and also it is not advisable.
Hope this will help.
