Monaca In-App Updater

This plugin updates HTML5 assets contained in the app without rebuilding and packaging the app. You need a Web server to host the update files which will be accessed from the app.

In order to use this plugin, you are required to subscribe to a valid plan. Please refer to Monaca Subscription Plans.

This plugin is not available for custom build debuggers. If you want to check the operation, you need to debug build the app.

Supported Platforms

• Cordova 7.1 or higher

• iOS 9 or later

  • For WKWebView version (5.0.5 or later): iOS 11 or later

  • CustomScheme supporting version（6.1.0 or later）: iOS 11 or later

• Android 4.1 or later

If you are using WKWebView, you need to use version 5.0.5 or later.

Create an HTML5 asset for update

Select the following from Monaca Cloud IDE and click the Start Build button.

• Build → Build App for Android → Build for Release → Create a package for In-App Updater

• Build → Build App for iOS → Build for Release → Create a package for In-App Updater

Usage

This plugin updates the HTML5 asset for the version of the target application. When updating the HTML5 asset, set a new update number in the update file on the web server side.

For the update file on the Web server side, see CheckUpdate URL.

Plugin Configuration

To use this plugin, you need two Web APIs (URL), CheckUpdate URL and Download URL.

CheckUpdate URL

Specifies the URL of the Web API that provides update file information. Update file information is created in JSON format as follows. It can be obtained by the updateInfo parameter of a JSON object returned by the promise of getServerVersion() method.

Request Parameters

API Reference

The easiest way to use this plugin is to only use autoUpdate() which will download the update files (as configure in Plugin Configuration) and update the app automatically.

On the other hand, if you want to customize the update process, you can use various available methods such as getServerVersion(), download(), updateAndRestart() and so on.

Here is the list of all available methods for this plugin:

Methods	Description
getServerVersion()	Get the information of files to be updated from the server.
forceStopGetServerVersion()	Force getServerVersion() to stop.
getLocalVersion()	Get the currect version of the app.
download()	Download the update files.
forceStopDownload()	Force download() to stop.
updateAndRestart()	Deploy and mount the downloaded update files, and then restart the app.
status()	Get the current status of the plugin.
showAlertDialog()	Show a dialog with a title and a message. Only one dialog is shown at a time.
dismissAlertDialog()	Close the Alert dialog.
showProgressDialog()	Show a Progress dialog indicating the update progress.
changeProgressDialog()	Change the Progress dialog.
dismissProgressDialog()	Close a Progress dialog.
networkStatus()	Check the network status (Wifi, 3G/LTE, or disconnected).
terminateApp()	Terminate/Shut down the app.
autoUpdate()	Update automatically if necessary, by using methods such as getServerVersion, download, etc.

        monaca.InAppUpdater.updateAndRestart().then(
        function() { },
        function(fail) { alert( JSON.stringify(fail) ); }

        function(fail) { }
    );
    }
});

Notes on Android 9+

In principle, http protocol communication is prohibited on Android 9 and later. Therefore, the update file needs to be modified to be obtained by https protocol.

If http protocol communication is required for the operation test, you need to add the usesCleartextTraffic by adding the andorid namespace to the widget tag of config.xml as shown below.

<widget xmlns:android="http://schemas.android.com/apk/res/android">

<platform name="android">
  <edit-config file="AndroidManifest.xml" target="/manifest/application" mode="merge">
    <application android:usesCleartextTraffic="true" />
  </edit-config>
</platform>

CustomScheme configuration (Cordova 10 or later + this plugin 6.1.0 or later, iOS only)

In iOS, we can set the scheme and hostname for this plugin. (Same as HTML5 Resource Encryption plugin)

The default scheme and hostname of Cordova 10 are as follows.

<preference name="scheme" value="monaca-app"/>
<preference name="hostname" value="localhost"/>

Please remove this default setting. If you specify this, you will get a build error.

You can then set the scheme and hostname in config.xml as follows.

<preference name="monaca:scheme" value="monacax-app"/>
<preference name="monaca:hostname" value="monacax.io"/>

In this example, the scheme is "monacax-app" and the hostname is "monacax.io". The characters that can be used in the scheme are as shown in RFC 2396 Appendix A

 scheme        = alpha *( alpha | digit | "+" | "-" | "." )

Also, if you omit monaca:scheme and moanca:hostname, they become monaca-plugin and monaca.plugin respectively.
