This is for PhoneGap 3.x, here is the 2.x version

1. Description

Prevent the screen of the mobile device from falling asleep.

• The device will never fall asleep after calling keepAwake.
• After making your app practically a zombie, you can allow it to sleep again by calling allowSleepAgain.
• Works on Android, probably every version you'd care about.
• Works on iOS, probably every version you'd care about.
• Works on Windows and WP8.

2. Installation

Automatically (CLI / Plugman)

Insomnia is compatible with Cordova Plugman and ready for the PhoneGap 2.9.0 CLI, here's how it works with the CLI:

$ phonegap local plugin add https://github.com/EddyVerbruggen/Insomnia-PhoneGap-Plugin.git

or

$ cordova plugin add https://github.com/EddyVerbruggen/Insomnia-PhoneGap-Plugin.git

run this command afterwards:

$ cordova prepare

The javascript bridge is brought in automatically, so no need to reference Insomnia.js from your html.

You can also get this plugin from NPM.

Manually

1. Add the following xml to your config.xml in the root directory of your www folder:

<!-- for iOS -->
<feature name="Insomnia">
  <param name="ios-package" value="Insomnia" />
</feature>

<!-- for Android -->
<feature name="Insomnia">
  <param name="android-package" value="nl.xservices.plugins.Insomnia" />
</feature>

<!-- for wp8 -->
<feature name="Insomnia">
  <param name="wp-package" value="Insomnia" />
</feature>

2. Grab a copy of Insomnia.js, add it to your project and reference it in index.html:

<script type="text/javascript" src="js/Insomnia.js"></script>

3. Download the source files for iOS and/or Android and copy them to your project.

iOS: Copy Insomnia.h and Insomnia.h to platforms/ios/<ProjectName>/Plugins

Android: Copy Insomnia.java to platforms/android/src/nl/xservices/plugins (create the folders)

wp8: Copy Insomnia.cs to platforms/wp8/Plugins/nl.x-services.plugins.insomnia (create the folders)

PhoneGap Build

Insomnia works with PhoneGap build too, look for Insomnia here: https://build.phonegap.com/plugins/ Just add the following xml to your config.xml to always use the latest version of this plugin:

<plugin name="cordova-plugin-insomnia-ios-base" />

or to use this exact version:

<plugin name="cordova-plugin-insomnia-ios-base" version="4.1.0" source="npm" />

The plugin's javascript file is brought in automatically. Make sure though you include a reference to cordova.js in your index.html's head:

<script type="text/javascript" src="cordova.js"></script>

3. Usage

<button onclick="window.plugins.insomnia.keepAwake()">keep awake</button>
<button onclick="window.plugins.insomnia.allowSleepAgain()">allow sleep again</button>

An optional successCallback (first argument) will be triggered if the functions succeed. Even calling keepAwake twice will fire the successCallback, because the app will respond as expected (being kept awake).

An optional errorCallback (second argument) will only be triggered if something fatal happened, preventing the plugin to work as expected.

Note that calling allowSleepAgain without calling keepAwake first will trigger errorCallback or throw an error if not provided.

Quirks

In this issue it was reported that on iOS the app would fall asleep after the Camera has been used, even if you previously called keepAwake. A similar issue on Android where the photo library was accessed during app usage.

So to make sure your app honors keepAwake you have to re-run that method after these kinds of 'external UI' thingies give control back to your app.

4. CREDITS

This plugin was enhanced for Plugman / PhoneGap Build by Eddy Verbruggen.
