AppDynamics supports monitoring for hybrid applications based on the iOS/Android native SDK or any Cordova-based framework.

What Are Hybrid Applications?

Hybrid applications are web applications running inside an Android or iOS native shell. The web application can be in the form of an Android WebView, an iOS WKWebViews, or a Cordova web application that consists of HTML, CSS, JavaScript, and other resources just like a conventional web application. 

Hybrid Use Cases

Mobile RUM supports the following two use cases.

  • Native Mobile applications that run web applications or web views. Examples of this are Android WebViews and iOS WKWebView.
  • Applications written in Cordova-based frameworks, such as Ionic, that provide a native shell for running a web application and an interface for native mobile APIs.

Instrumentation Steps

To monitor your hybrid applications, you will need to set up and access Mobile RUM and follow the steps below based on your hybrid use case:

How it Works

For native Android/iOS applications, the Android Agent or iOS Agent will inject the JavaScript Agent into an Android WebView or iOS WKWebView. For Cordova-based applications, the AppDynamics plugin will inject the JavaScript Agent into the web application. 

The diagrams below provide an overview of how Mobile RUM is used to monitor mobile native applications and Cordova-based applications.

Mobile Native Application Architecture

You instrument your mobile application with either the Android/iOS Agent.

When your mobile application instantiates a WebView or WKWebView instance, the Mobile Agent injects the JavaScript Agent into it.

The JavaScript Agent monitors the performance and WebView usage.

The JavaScript Agent reports the application activity by sending beacons to the Mobile Agent.

The Mobile Agent repackages the browser beacons into mobile beacons and sends the beacons to the EUM Server.

Cordova-Based Application Architecture

The AppDynamics Cordova plugin injects the JavaScript Agent into the Cordova WebView.

 The Cordova-based application uses the plugin's JavaScript binding to configure the Mobile Agent.

The JavaScript Agent injected into the WebView monitors the application activity and performance.

 The JavaScript Agent sends browser beacons to the Mobile Agent.

 The Mobile Agent parses and converts the browser beacons into mobile beacons.

The Mobile Agent sends the mobile beacons to the EUM Server.
