Apache Cordova: Develop Mobile Applications | You Should Know it

What is Cordova?

Further, let us discuss Hybrid applications.
Apache Cordova


Today, we will talk about a platform that is very useful for mobile app developers called " Apache Cordova". First of all, let us study what actually the Native and Hybrid Applications are? Let us first talk about Native applications. 

Since the app is formed within a sophisticated environment following the scientific and user practice guidelines of the OS (e.g. Swipes, app defined signals, left aligned header on Android, a midway aligned header on iOS,), it not only has the benefit of faster appearance but also “feels right”. 

What sense best means is that in-app communication has a look and feel consonant with most of the other native apps on the device. The end-user is thus more likely to learn how to operate and use the app faster. 

Finally, native applications have the significant advantage of being able to easily access and utilize the built-in abilities of the user’s device (e.g., GPS, address book, camera, etcetera). When a user conveys text information, takes pictures using the device’s default app, set reminders, or uses the device’s music app (the one that came with the phone), they’re using native apps.

💥How it is used to Develop Native Applications?



Further, let us discuss Hybrid applications. These applications view and feel like an original app, but eventually outside of the basic framework of the application (basically restricted to the limitations/ navigational elements) they are serviced by a company’s website. 

Basically, a hybrid app is a form of a web app which includes using HTML5 and JavaScript, wrapped in a native container that loads most of the collection of information on the page as the user operates through the application (Native apps rather download most of the content when the user first installs the app). Common suspects here are Facebook, Twitter, Instagram, your mobile banking app, etcetera.

💥Cordova Overview:

Cordova is an open-source mobile growing structure. It allows you to use standard web technologies - HTML, CSS, and JavaScript for cross-platform advancement. You should know one thing, These Applications actually execute within wrappers targeted to each and every platform and rely on standards-compliant API bindings which helps to access each device's capabilities like sensors, data, network status, etc.

💥Use Apache Cordova if You are:

  • A mobile developer and you want to extend an application across more than one platform, without having to re-implement it with each platform's language and toolset without change anything, I am sure, you will use it.

  • A web developer and you want to deploy a web app that's packaged will be used in the distribution in various types of app store portals.



  • A mobile developer who is really interested in mixing native application components with a WebView (special browser window) that can access device-level APIs.

  • If you want to develop a plugin interface between native and WebView components then it's for you

💥Who can use Cordova?

Cordova is supported on platforms such as IOS, Opera Mini, Blackberry, Firefox, etc. If you Web Developer, and want to develop the applications that can be deployed on different app portals. If you want to develop a Native Mobile Developer, and want to develop a single application on the different platforms without having to re-implement the application code for implementation.


Configurations:

  • Prerequisites
  • Node JS
  • Target SDK
  • From Command line
  • >sudo npm install -g Cordova
  • To know the install version 
  •  Cordova ~v



Cordova Command line:

To create an application
> cordova create <<app_dir>> <<project_id>> <<app_title>>
To add a platform (from app builder)
> cordova platform add <<platform_name>>

To build Cordova projects 
> Cordova build

To deploy app on emulator 
> cordova emulate <<platform_name>>

💥Cordova API'S:

1).Camera

An Object that provides access to the default camera applications.
Code:
var captureSuccess = function(mediaFiles) {
};
var captureError = function(error) {
navigator.notification.alert('Error code: ' + error.code, null, 'Capture Error');
};
navigator.device.capture.captureAudio(captureSuccess, captureError, {limit:2});


2).Media

An object that allows performing audio files on the device.
Code:
var my_media = new Media("someFile.mp3", onSuccess, onError);
my_media.play();
function onSuccess() {
console.log("playAudio():Audio Success");
}
function onError(error) {
alert('code: ' + error.code + '\n' + 'message: ' + error.message + '\n');
}



3).Jquery Integration

In order to boost the performance of JQuery with Cordova, it is recommended to disable transition effects as given below
(JQuery mobile 1.4)
$.mobile.defaultPageTransition = 'none' ;
$.mobile.defaultDialogTransition = 'none' ;

💥Pros:

You don't have to study any new languages if you're previously a decent web developer. It's very agile to prototype. Though we didn't end up using it, JQuery mobile is pretty neat too and performs even faster prototypes. 

Lots of archives options for pretty much everything you could possibly want. It's really cool and fun. If you hence wanted to, you can avoid the app store by hosting the files on a server, and utilize app cache to make things speedy.

💥Cons:

There are a number of mobile browsers out there (the case of browsers is worse than its ever been in terms of how many several crappy ones we have to support it used to be just ie, but guess how many frames are on android 2.x). 

There are a number of mobile gadgets out there with varying hardware configurations, portability, and network speed.
