// Wait for Cordova to load

document.addEventListener("deviceready", onDeviceReady, false);
// Cordova is ready
//
function onDeviceReady() {
window.requestFileSystem(LocalFileSystem.PERSISTENT, 0, gotFS_w, fail);
}
function gotFS(fileSystem) {
fileSystem.root.getFile("readme.txt", null, gotFileEntry, fail);
}
function gotFileEntry(fileEntry) {
fileEntry.file(gotFile, fail);
}
function gotFile(file){
readDataUrl(file);
readAsText(file);
}
function readDataUrl(file) {
var reader = new FileReader();
reader.onloadend = function(evt) {
console.log("Read as data URL");
console.log(evt.target.result);
};
reader.readAsDataURL(file);
}
function readAsText(file) {
var reader = new FileReader();
reader.onloadend = function(evt) {
console.log("Read as text");
console.log(evt.target.result);
};
reader.readAsText(file);
}
function fail(error) {

}
function gotFS_w(fileSystem) {
fileSystem.root.getFile("readme.txt", {create: true, exclusive: false},
gotFileEntry_w, fail);
