AIR Namespace 1.5.1 in the application descriptor报错解决

Namespace 1.5.1 in the application descriptor file should be equal or higher than the minimum version 2.6.0 required by Flex SDK.

将xxxx_app.xml种的

<?xml version="1.0" encoding="UTF-8"?>
<application xmlns="http://ns.adobe.com/air/application/1.5.1">

替换为

<?xml version="1.0" encoding="utf-8" standalone="no"?>
<application xmlns="http://ns.adobe.com/air/application/2.6">
