android cordova phonegap config.xml未绑定前缀

Question

I have the following config.xml file for my android app, and I am trying to install launchmyapp plugin. Everytime I clean, I get this the following error

/code/platforms/android/res/xml/config.xml:21: error: Error parsing XML: unbound prefix

I checked other stack questions and everyone is pointing to wrong formatting in the parameter fields, but all seems ok...

here is the config.xml

<?xml version='1.0' encoding='utf-8'?>
    <widget id="com.myappname.Myappname" version="2.2.3" xmlns="http://www.w3.org/ns/widgets" xmlns:cdv="http://cordova.apache.org/ns/1.0">
    <name>MyAppName</name>

</widget>

Answer 1

I've encountered the same question as yours. I supposed it's because <gap:plugin> must be bound to phonegap prefix.

So I solved this question by adding xmlns:gap="http://phonegap.com/ns/1.0" at node.

In your case, the full <widget> should be:

<widget id="com.myappname.Myappname" version="2.2.3"  xmlns="http://www.w3.org/ns/widgets" xmlns:cdv="http://cordova.apache.org/ns/1.0" xmlns:gap="http://phonegap.com/ns/1.0">

Hope it works for you.
