How do I change minsdkversion?

Hey, I was just wondering what is the easiest way to change the minsdkversion of app. I have been trying to do this for months with no success. If anyone can give me step by step instructions I will be so thankful. Android Studio seems too confusing.

After exporting your project go the folder and open Config.XML and Config.json

in Config.XML you will find something like this:

<preference name="android-minSdkVersion" value="19" />

Change the number for this --> value="19" --> to what you want,

next go to Config.json and look for ( under Android ) :

"min": 19

and same thing do here, change it as well, but the number must be the same as before.

PS. be sure to check what google minsdkversion because I remember they require now 21 or 23 not sure.

Good luck hope this help

Do I export it as a Cordova project or what?
