I have a hybrid application in Android which involves native functions as well :
HTML 5 with javascript :
<html>
<head>
<script src="jquery-1.5.1.min.js"></script>
<script src="menus.js"></script>
<script src="jquery-ui-1.8.10.custom.min.js"></script>
<script type="text/javascript">
function openCamera1(){
camera.startCameraActivity1();
var path1=camera.getImagePath1();
alert(path1);
document.getElementById("image1").src=path1;
}
function openCamera2(){
camera.startCameraActivity2();
var path2=camera.getImagePath2();
alert(path2);
document.getElementById("image2").src=path2;
}
function show_confirm() {
var r=confirm("Do you wish to use the existing Details?");
if (r==true)
{
alert("You pressed OK!");
} else {
alert("You pressed Cancel!");
}
}
in html :
<input type="button" onclick="show_confirm()" value="Register Cliam" />
in java : (android native):
public String getDetails(){
System.out.println("iiiiiiiiiiiiiiii");
String a=dh.hello();
System.out.println("aaaaaaaaaaaa " + a);
return a;
}
Data helper class :
public String hello(){
return "Hello";
}
And Exception i am facing :
