You can add a webview widget in xml file of activity then you have to connect it with activity.java file and then have to add the INTERNET user permission in the manifest file, but one last thing for opening http server is allowing your app Uses clear text traffic.(to open http website). Actually webview by default don't open unsafe website, without this step you can still open the https website as it is secure and uses encryption. On the other side http is plain text. so for opening this file you have to follow the last step other wise it webpage will not be loaded by saying - ERR_CLEARTEXT_NOT_PERMITTED

All the files
