Question

In PhoneGap how do I create/open a database in Android?

I am using this code to create a database:

function onDeviceReady() {
        alert("okey");
        var db = window.openDatabase("Database", "1.0", "PhoneGap Demo", 200000);
 }

then, in console it prints this error message:

E/Web Console(13516): TypeError: Result of expression ‘db’ [null] is not an object. at file:///android_asset/www/index.html:24

How can I remove this problem?

Answer 1

I think your problem is with scope of db variable. Try this

var db;
function onDeviceReady() {
        alert("okey");
        db = window.openDatabase("Database", "1.0", "PhoneGap Demo", 200000);
 }
