Cordova Tutorial Pdf

[Melanie Wendelberger]

Thisguide shows you how to create a JS/HTML Cordova application and deploy them tovarious native mobile platforms using the cordova command-lineinterface (CLI). For detailed reference on Cordova command-line, review the CLI reference

(Optional) Download and install a git client, if you don'talready have one. Following installation, you should be able to invoke giton your command line. The CLI uses it to download assets when they are referenced using a url to a git repo.

On OS X and Linux, prefixing the npm command with sudo may be necessary to install this development utility in otherwise restricted directories such as /usr/local/share. If you are using the optional nvm/nave tool or have write access to the install directory, you may be able to omit the sudo prefix. There are more tips available on using npm without sudo, if you desire to do that.

This creates the required directory structure for your cordova app. By default, the cordova create script generates a skeletal web-based application whose home page is the project's www/index.html file.

Note: When using the CLI to build your application, you shouldnot edit any files in the /platforms/ directory. The filesin this directory are routinely overwritten when preparingapplications for building, or when plugins are re-installed.

To build and run apps, you need to install SDKs for each platform you wish to target. Alternatively, if you are using browser for development you can use browser platform which does not require any platform SDKs.

By default, cordova create script generates a skeletal web-based application whose start page is the project's www/index.html file. Anyinitialization should be specified as part of the deviceready event handler defined in www/js/index.js.

SDKs for mobile platforms often come bundled with emulators thatexecute a device image, so that you can launch the app from the homescreen and see how it interacts with many platform features. Run acommand such as the following to rebuild the app and view it within aspecific platform's emulator:

A plugin exposes a Javascript API for native SDK functionality. Plugins are typically hosted onnpm and you can search for them on the plugin search page. Some key APIs are provided by the Apache Cordova open source project and these are referred to as Core Plugin APIs. You can also use the CLI to launch the search page:

NOTE: The CLI adds plugin code as appropriate for each platform.If you want to develop with lower-level shell tools or platform SDKsas discussed in the Overview, you need to run the Plugman utility toadd plugins separately for each platform. (For more information, seeUsing Plugman to Manage Plugins.)

While Cordova allows you to easily deploy an app for many differentplatforms, sometimes you need to add customizations. In that case,you don't want to modify the source files in various www directorieswithin the top-level platforms directory, because they're regularlyreplaced with the top-level www directory's cross-platform source.

Instead, the top-level merges directory offers a place to specifyassets to deploy on specific platforms. Each platform-specificsubdirectory within merges mirrors the directory structure of thewww source tree, allowing you to override or add files as needed.For example, here is how you might use merges to boost the defaultfont size for Android devices:

You can also use merges to add files not present in the originalwww directory. For example, an app can incorporate a back buttongraphic into the iOS interface, stored inmerges/ios/img/back_button.png, while the Android version caninstead capture backbutton events from the corresponding hardwarebutton.

Cordova is a platform that is used for building mobile apps using HTML, CSS and JS. We can think of Cordova as a container for connecting our web app with native mobile functionalities. Web applications cannot use native mobile functionalities by default. This is where Cordova comes into picture. It offers a bridge for connection between web app and mobile device. By using Cordova, we can make hybrid mobile apps that can use camera, geolocation, file system and other native mobile functions.

We are creating this tutorial for HTML, CSS and JavaScript developers that want to learn about mobile development. During the course we will go through most of the Cordova key points and we will show you how to use most of the Cordova plugins.

All of the examples provided can be used as a starting point in your own apps. We will also try to explain theory behind Cordova so you can get better picture of building process of hybrid mobile apps. We will try to show you examples as simple as possible so you can understand the essential principle of the Cordova development.

You need to be familiar with HTML, CSS and JavaScript. If you ever created single page apps (SPA), that knowledge will be useful when working with Cordova but it is not necessary to understand most of the things this tutorial offers.

I am on the second page ( -resources/guides/first-app-v4/ios-android-camera/) to the point where it tells me to launch it in DevApp and try taking a photo. I only get cordova_not_available no matter what I try.

I just saw that the newest version of Ionic DevApp was released on the Play store for Android, and states that it is compatible with Ionic version 4.10 (which I am currently running). However, this issue still persists for me with the newest version of DevApp and the CLI. Should this be working with this version, or is this still a known issue?

Another update. I found the root of the issue: to run an app on DevApp, we first need to add a reference to cordova.js in your index.html file. Open up the file at src/index.html and add the following tag into the section.

I have been running through the Cordova tutorial for installation and creating a first app. After spending the last few hours trying to figure this out I have pretty much reached a dead end. I'm currently running Ubuntu and trying to build on Android 4.0.0.

When I installed Android I did it through the Android Studio download. After installing, I went to the SDK Manger in the UI and updated the 3 files listed in the error above. For some reason this did not update in the SDK where my $ANDROID_HOME path was set to which was /home/prawg/Android/Sdk

In this tutorial, you will learn strategies and best practices to build native-like mobile applications withHTML, JavaScript, and CSS. You will build an Apache Cordova (aka PhoneGap) Employee Directory application from scratch using the Single Page Architecture, HTML templates, touch events, and performance optimization techniques.

A mobile device or a Mobile SDK is not a requirement for this tutorial. However, if you want to run and test the application on a mobile device or on an emulator for a mobile platform supported by Cordova, you need the Mobile SDK for that platform (iOS SDK, Android SDK, etc.) installed on your system. If you don't want to install a Mobile SDK, you'll be able to test your application in a browser on your computer.

Greetings. I am creating an app using cordova. Is there a way to show welcome screen or tutorial screen on start of the app. i want to show 3 or 4 slides with a button in the last slide. when user click the button i want the welcome screen to close. and i want to show welcome screen only the first time after the app is installed.

I am learning Rust and Wasm. I made a simple memory game. It is more a tutorial how things work.

I tried to build it as a phonegap or cordova app for android.

But it does not work.

The code is here:

_phonegap

I found the problem and solved it.

The wasm file is opened in javascript in an ajax call.

Modern browsers don't alow ajax on local files.

PhoneGap app works with local files.

I changed the location of the wasm file to an URL on github and now it works.

The great thing about Ionic is that with one codebase, you can build for any platform using just HTML, CSS, and JavaScript. Follow along as we learn the fundamentals of Ionic app development by creating a realistic app step by step.

Run the following in the command line terminal to install the Ionic CLI (ionic), native-run, used to run native binaries on devices and simulators/emulators, and cordova-res, used to generate native app icons and splash screens:

The prompt might show you a recommendation to use Capacitor instead of Cordova. Capacitor is the successor of Cordova. For more details, please see our Capacitor blog post. For this tutorial, we will stick with Cordova.

Open the Xcode workspace platforms/ios/my_awesome_cordova_ionic_app.xcworkspace

and adjust the Signing & Capabilities settings in the Xcode IDE by selecting your Apple developer account. Then build and run the app in Xcode.

Furthermore, we need to declare that our app works with the camera and requires the corresponding permission. Make sure the request for camera permission has been properly added by the Scanbot Cordova plugin.

The Scanbot Scanner SDK for Cordova provides a scanner UI for document scanning. The Document Scanner is a complete and ready-to-use screen component. It can be easily integrated with just a few lines of code using the API method SDK.UI.startDocumentScanner(uiConfigs: configs).

With the DocumentScannerConfiguration, you can pass further config parameters to customize colors, text resources, and the behavior of some features of the Document Scanner. See the API docs for more details.

Please note: The Scanbot SDK will run without a license key for one minute per session! After the trial period has expired, all Scanbot SDK functions, as well as the UI components, will stop working or may be terminated.

As the Scanbot SDK license key is bound to an app identifier (i.e., Application ID on Android and Bundle Identifier on iOS), you will have to use the app identifier com.example.hello that we defined at the beginning of the tutorial when creating the app. Of course, you can also use the ID of your app to get a trial license. Please also note that app IDs are case-sensitive!
