Apache Cordova is an open-source mobile development framework. Applications execute within wrappers targeted to each platform, and rely on standards-compliant API bindings to access each device's capabilities such as sensors, data, network status, etc.
There are several components to a Cordova application. The following diagram shows a high-level view of the Cordova application architecture. The Cordova-enabled WebView may provide the application with its entire user interface. On some platforms, it can also be a component within a larger, hybrid application that mixes the WebView with native application components.
See Embedding WebViews for details. This is the part where your application code resides. The application itself is implemented as a web page, by default a local file named index.
Cordova SDK Troubleshooting
Apache Cordova project maintains a set of plugins called the Core Plugins. These core plugins provide your application to access device capabilities such as battery, camera, contacts, etc. In addition to the core plugins, there are several third-party plugins which provide additional bindings to features not necessarily available on all platforms. You can search for Cordova plugins using plugin search or npm. You can also develop your own plugins, as described in the Plugin Development Guide.
Plugins may be necessary, for example, to communicate between Cordova and custom native components. This is the new default behavior. Any plugins you desire, even the core plugins, must be explicitly added. Cordova provides only the runtime in which those can execute.
Cordova provides you two basic workflows to create a mobile app. While you can often use either workflow to accomplish the same task, they each offer advantages:.
Cross-platform CLI workflow : Use this workflow if you want your app to run on as many different mobile operating systems as possible, with little need for platform-specific development. This workflow centers around the cordova CLI. The CLI is a high-level tool that allows you to build projects for many platforms at once, abstracting away much of the functionality of lower-level shell scripts.
The CLI copies a common set of web assets into subdirectories for each mobile platform, makes any necessary configuration changes for each, runs build scripts to generate application binaries.App Center Analytics helps you understand user behavior and customer engagement to improve your app.
You can define your own custom events to measure things that matter to you. All the information captured is available in the App Center portal for you to analyze the data.
You can track your own custom events with up to twenty properties to understand the interaction between your users and the app. Once you have started the SDK, use the trackEvent method to track your events with properties. You can send up to distinct event names. Also, there is a maximum limit of characters per event name and characters per event property name and event property value.
This function uses third parameter as success callback which returns an empty string and fourth parameter as error callback which returns an error. Properties for events are entirely optional. If you just want to track an event, use this sample instead:. You can enable and disable App Center Analytics at runtime. If you disable it, the SDK will not collect analytics information for the app anymore.
This function uses second parameter as success callback which returns an empty string and third parameter as error callback which returns an error. This function uses first parameter as success callback which returns a boolean and second parameter as error callback which returns an error. In some cases, an application may want to ask users whether they want to share analytics information.
This means that for any information to be sent to App Center even basic session informationthe developer must first enable App Center Analytics inside the app by adding the following line to his code. Once the storage is full, the SDK will start discarding old logs to make room for the new logs. Once the device gets internet access back, the SDK will send logs in the batch of 50 or after every 3 seconds.
There can be a maximum of 3 batches sent in parallel. App Center SDK supports back-off retries on recoverable network errors.

Or is development restricted to only native languages Objective-C or swift? Just realize that you will be dependent on the third-party for support as these forums are restricted to Apple development tools only.
Even Objective-C seems to be somewhat unwelcome in tvOS? All the examples I've seen are in Swift gulp. You use Cordova for multi-platform use. You use Obj-C for one-platform use. Let the developer decide which is best for him or her. But it's inappropriate to come to an Apple forum when said third-party tools are part of the equation. Third-party tools are always part of the equation. Or wait for others to finish doing so.
You should be able to when the third-party updates their code. Check with them.Comment 0. So a few days ago, someone on Twitter sorry, I forget whomentioned that the new Apple TV has some pretty stellar screen savers. Turns out the data for those screen savers was all driven by a public JSON file. You should check it out. Absolutely beautiful stuff.
Now it looks like everyone is playing with it. You can even get a OSX and Windows screen saver of the videos. Here it is in action. Obviously your world may differ. Then we can just select a random video and return it. I could add a label to the display so folks knew what it is.
I could also add support for knowing when you are offline.

You can test many of the Cordova features using the iOS simulator that is installed with the iOS SDK and Xcode, but you will need an actual device to fully test all of the device features used in your applications before submitting to the App Store. The device must have at least iOS 5. In addition, to install apps onto a device, you must be a member of the iOS Developer Program from Apple.
This Getting Started guide documents deploying the application to the iOS simulator so registration with the developer program is not required.
iOS Platform Guide
Click on the Download icon and select cordova-X. The X, Y and Z represent the version number of Cordova, for example 2. The download includes the code for all of the Apache Cordova supported platforms. Navigate to the folder where you downloaded the code.
Find the cordova-X. Note: The file names change with each new version of Cordova. The file name will be different if you are using an updated or newer version of Cordova. This will create a directory named, cordova-X. Xcode projects for Cordova are created by invoking a script file via the command line.
The following steps explain how to create the necessary directory structure, open and use the Terminal application to create a new project, and execute the create script. Determine where on your system you will locate the Xcode project files for your application. Create a directory called CordovaXY within the Documents directory where the X and Y represent the Cordova version number 23, for example.
You can use a different directory name or location if you wish but you will need to remember this directory location and name for subsequent steps. In Finder, navigate to the cordova-ios directory from the downloaded and extracted Cordova code and expand it if necessary.
Highlight the bin directory as shown:. Note: This screen capture was from the CordovaThis guide shows how to set up your SDK development environment to deploy Cordova apps for iOS devices such as iPhone and iPad, and how to optionally use iOS-centered command-line tools in your development workflow.
You need to install the SDK tools regardless of whether you want to use these platform-centered shell tools or cross-platform Cordova CLI for development.
For a comparison of the two development paths, see the Overview. You can test many of the Cordova features using the iOS simulator installed with the iOS SDK and Xcode, but you need an actual device to fully test all of the app's device features before submitting to the App Store. The device must have at least iOS 9 installed, the minimum iOS version supported since the release of cordova-ios v4. Once Xcode is installed, several command-line tools need to be enabled for Cordova to run.
From the command line, run:. Installing Xcode will mostly set everything needed to get started with the native side of things. You should now be able to create and build a cordova project.
For more details on installing and using the CLI, refer to Create your first app guide. Select the intended device from the toolbar's Scheme menu, such as the iPhone XR Simulator as highlighted in 2. Press the Run button 3 in the same toolbar to the left of the Scheme. That builds, deploys, and runs the application in the simulator. A separate simulator application opens to display the app:.
Only one simulator may run at a time, so if you want to test the app in a different simulator, you need to quit the simulator application and run a different target within Xcode. Xcode comes bundled with simulators for the latest versions of iPhone and iPad. Briefly, you need to do the following before deploying:.
You can use its Development Provisioning Assistant to create and install the profile and certificate Xcode requires. Verify that the Code Signing Identity setting within the Code Signing section within the build settings is set to your provisioning profile name. Select your device from the Device drop-down list. If it is plugged in via USB but still does not appear, press the Organizer button to resolve any errors.
