Tell me about restrictions for developing Windows Store apps.

For Windows Store app development, native JavaScript and HTML5 features are used. Therefore, features such as those in PhoneGap cannot be used. For this reason, in order to develop an app runs on both Windows (Windows store app) and other platforms, you can’t use features such as those in PhoneGap. Also, for Windows Store app, there are some features and properties in the standard JavaScript and HTML5 that can’t be used. For more details, please refer to HTML, CSS, and JavaScript features and difference.

Can I develop a full-screen app?

Yes, you can. However, you need to make configuration differently on iOS and Android.

Android

There are two ways to make an app runs in fullscreen mode:

  1. By Android App Configuration panel: From Monaca Cloud IDE, go to Config → Android App Settings . Then, enable the Fullscreen mode.

  2. By config.xml file: input the following line within the file:

    <preference name="Fullscreen" value="true"/>

iOS

You need to use StatusBar Plugin to hide the native status bar.

To ensure the configuration is updated successfully, please build your app again after making the above configuration.

Can I always use the latest version of Cordova?

Monaca supports specific Cordova versions. However, we regularly update and provide the latest Cordova version support as soon as possible.

Cordova API and Monaca JavaScript API do not work.

Please check your code if components/loader.js file is loaded. You can’t use Cordova API and other JavaScript APIs provided by Monaca if the file was not loaded.

How to change the app start page from index.html to another?

  1. Go to config.xml file under www folder.
  2. Under <widget> element, input the location of the file you want for the starting page in the <content> tag. The default value is index.html. See the example below:

    <?xml version="1.0" encoding="UTF-8"?>
    <widget xmlns="http://www.w3.org/ns/widgets" id="com.example.helloworld" version="1.0.0">
        ...
        <content src="https://monaca.io/" />
    </widget>
This method won’t work in Android Debugger downloaded from Google Play. Creating a custom Android debugger will solve this issue. Please refer to Build and Install Custom Monaca Debugger .

Limitation of version number and version code for Monaca apps

Based on Cordova, the maximum value of version number is 99.99.99 and the corresponding maximum value of version code is 999999 for Monaca apps.

If you want to use a larger version code value, you need to modify config.xml file directly. See below example:

<widget xmlns="http://www.w3.org/ns/widgets" id="your packagename" version="xx.yy.zz">
<!--Substitute xx.yy.zz to 100.1.3, the version code becomes 1000103.-->
Starting from 2014/04/02, config.xml file is located under www folder. If your project is created before that, config.xml file is located as android/config.xml and ios/config.xml for Android and iOS respectively.

Cordova APIs (such as camera, compass, and so on) are not working

When using Cordova APIs (such as camera, compass, and so on), you need to make sure that those APIs are called after they have loaded and are ready to access.

The deviceready event fires once the Cordova has fully loaded. You can safely use Cordova APIs when this event is fired. For more information, please refer to deviceready event.

For Onsen UI, ons.ready() function is called when both deviceready and DOMContentLoaded events are fired. Therefore, you can deal with both events by using ons.ready() function.

The built app does not work, or works differently than what it runs on the debugger.

It is likely that the built app does not contain the necessary Cordova plugin. Although Monaca Debugger contains all core plugins by default, you need to manually specify which plugin to install when you build the app. You can manage the plugins to include in the app by enabling in Manage Cordova Plugins configuration.

How to make iOS’s App ID and Android’s Package Name differently.

Currently, when you update either iOS’s App ID or Android’s Package Name, both of them will change. In other words, they are configured to be the same. However, it is possible to make them different.

In order to create iOS’s App ID and Android’s Package Name differently, please update the <widget> tag in config.xml file by adding the values for android-packageName and ios-CFBundleIdentifier while removing the existing id value. Here is an example of the updated file:

<widget xmlns="http://www.w3.org/ns/widgets" android-packageName="com.example.android" ios-CFBundleIdentifier="com.example.ios" version="1.0.0”>
With this kind of configuration, all builds are succeeded except Android’s custom Debugger build .
