Save Image/File into sdcard in Android using PhoneGap


Mostly we call webservice and pass data as json format and we can easily fetch data for android application but sometimes when you fetching image from server it’s take much time to load and even if no internet,image can’t be load.
So, To cache image or to save loading time of image from server in every page load, we can store image into local. It’s very easy to store image into local using PhoneGap.

Let’s understand the code:
document.addEventListener("deviceready", onDeviceReady, false);
 
function onDeviceReady() {
//request the persistent file system
    window.requestFileSystem(LocalFileSystem.PERSISTENT, 0, fileSystemSuccess,
fileSystemFail);
}

function fileSystemSuccess(fileSystem) {
    var directoryEntry = fileSystem.root; // to get root path to directory
    directoryEntry.getDirectory("<folder_name>", {create: true, exclusive: false},
onDirectorySuccess, onDirectoryFail);
    var rootdir = fileSystem.root;
    var fp = rootdir.fullPath;
    fp = fp+"/<folder_name>/image_name.png";
    var fileTransfer = new FileTransfer();
   fileTransfer.download("<url_to_download>",fp,  
        function(entry) {
         alert("download complete: " + entry.fullPath);
     },
     function(error) {
         alert("download error source " + error.source);
         alert("download error target " + error.target);
         alert("upload error code" + error.code);
     }
    );
}
function onDirectorySuccess(parent) {
    console.log(parent);
}
 
function onDirectoryFail(error) {
    alert("Unable to create new directory: " + error.code);
}
 
function fileSystemFail(evt) {
    console.log(evt.target.error.code);
}

Some time Error occurred like : Source URL is not in white list: 'http://abc//santosh.png

Solution :

Change your cordova.xml or phonegap.xm in project directory res>xml>cordova.xml

<access origin="http://127.0.0.1*"/>

Replaced By :

<access origin="*" subdomains="true"/>

This white-lists basically the entire internet. If you only want to white-list your domain, use something more specific. See details here:

What exactly means MVW design pattern ?

What is a MVW framework? The abbreviation stands for 'Model - View - Whatever'.  Well there are many different JavaScript frameworks available , all invented for the same purpose. They all try to separate the presentation logic from the business logic where JavaScript holds the model and logic, and html the presentation layer. Quick overview : You can change the model without changing the view and vice-versa Unit testing is easy These are the core benefits of using such a framework. By separating presentation and business logic changes to the code are easier to implement and take less time. Another benefit is that code can be reused from a controller thus saving more time. Angularjs makes the code also shorter in comparison to other frameworks, which improves code stability. Less code means minor potential for bugs. For several years +AngularJS was closer to MVC (or rather one of its client-side variants), but over time and thanks to many refactorings...

Steps To Create Cordova Plugin

Introduction A plugin is a package of injected code that allows the Cordova webview within which the app renders to communicate with the native platform on which it runs. Plugins comprise a single JavaScript interface along with corresponding native code libraries for each supported platform. Due to following reason, we will go for plugin development To get the native capabilities of the device in the cordova based app Build the common functionality across the number of Cordova application(Reusability) Prerequisites For the creation of plugin you need to install plugman . npm install -g plugman Plugin Structure Decide Plugin ID & Name The plugin ID should be unique Plugin name should follow the convention “cordova.plugin.[your.plugin.name]” Create the structure Use the following command to create the plugin with plugin ID “cordova.plugin.test” and name “Test”. plugman create --name Test --...
