Answer 1

/**
 * Creates / Opens a connection to DB
 */
DB.openDB = function() {
    try {
        if (!window.openDatabase) {
            //alert('Cannot open database!');
        } else {
            var shortName = 'db_name';
            var version = '1.0';
            var displayName = 'DBNAME';
            var maxSize = (DEVICE_TYPE == DEVICE_ANDROID || DEVICE_TYPE == DEVICE_ANDROID_TAB) ? 5242880 : 1000000; ////819200; //65536; // in bytes // increased to support Android//163840; // 
            this.vocabDB = window.openDatabase(shortName, version, displayName, maxSize, this.DBCreated);
            this.DBSupported = true;
        }
    } catch(e) {
        //console.log("DB Error handling code goes here.");
        //console.log(e);
        return;
    }
}

Well, you can do a window.openDatabase() to a database in the assets folder. You'll need to copy it to the right place so that the WebView will load it. Check out this:
