button action with javascript not working

Hi

I created a pdf mathematic scool book for children

this book has the option to submit every page as a form to the teacher

on every page on the bottom the student has a button when he clicks it

i run a javascript code that sends the field on the page to the teachers email as a fdf file

all is working grate on pc

on android when i click the submit button nothig happens.

this is the code

// send to teacher
var currentDate = new Date()
var day = currentDate.getDate()
var month = currentDate.getMonth() + 1
var year = currentDate.getFullYear()
var todayDate = day + "/" + month + "/" + year; 
 
var lineBrake = "%0D%0A";
 
var teacherEmail = getField("email_teacher").value;
var teacherName = getField("name_teacher").value;
 
var studentEmail = getField("email_student").value;
var studentName = getField("name_student").value;
 
if(teacherEmail==""){
    app.alert("enter teachers email");
}
else if(teacherName==""){
    app.alert("enter teachers name");
}
else if(studentEmail==""){
    app.alert("enter student email");
}
else if(studentName==""){
    app.alert("enter students name");
}
else{
               
                var emailSubject = "work page from:" + studentName;
               
                var emailBody = "attached work page from:" + studentName + lineBrake + todayDate;
 
                 
    var aSubmitFields = new Array(
        "lesson1-page8-1a",
        "lesson1-page8-1b",
        "lesson1-page8-1c",
        "lesson1-page8-1d",
        "lesson1-page8-1e",
        "lesson1-page8-1f",
        "lesson1-page8-2b1",

        "lesson1-page8-2c3",
        "email_teacher",
        "name_teacher",
        "email_student",
        "name_student"       
    );
 
 
    this.submitForm({
      cURL: "mailto:"+teacherEmail+"?subject=" + emailSubject + "&body=" + emailBody,
      aFields: aSubmitFields,
      cSubmitAs: "FDF" // the default, not needed here
