When I ran the project on Chrome browser the ajax requests worked fine but when I installed the app on Android the requests are not working anymore. This is the code:

    var xhr=new XMLHttpRequest()
            xhr.onerror=function(){
           
                var message=alert(txt('Please turn on mobile data or Wi-Fi','Ligue os dados moveis ou Wi-Fi'))
                
            }
            
            xhr.onreadystatechange=function (){
                if (this.status== 200 && this.readyState == 4){ 
                alert("trye")
                  eval(xhr.responseText)
                
                } 
            }
            xhr.open("POST",`http://dpreaction.ml?i=js`)
            xhr.setRequestHeader('Content-type','application/x-www-form-urlencoded')
            xhr.send()

the config.xml file
