I'm using Plugman to create a simple plugin.
But unable to compile success in Android.

The reason is in plugin.file

Default plugin.xml

<?xml version='1.0' encoding='utf-8'?> <plugin id="SimpleMath" version="1.0.0" xmlns="http://apache.org/cordova/ns/plugins/1.0" xmlns:android="http://schemas.android.com/apk/res/android"><name>MyMath</name><js-module name="MyMath" src="www/MyMath.js"><clobbers target="cordova.plugins.MyMath" /></js-module><platform name="android"><config-file parent="/*" target="res/xml/config.xml"><feature name="MyMath"><param name="android-package" value="SimpleMath.MyMath" /></feature></config-file><config-file parent="/*" target="AndroidManifest.xml"></config-file><source-file src="src/android/MyMath.java" target-dir="src/SimpleMath/MyMath" /></platform></plugin>

Fixing plugin.xml (edit target-dir)

<?xml version='1.0' encoding='utf-8'?> <plugin id="SimpleMath" version="1.0.0" xmlns="http://apache.org/cordova/ns/plugins/1.0" xmlns:android="http://schemas.android.com/apk/res/android"><name>MyMath</name><js-module name="MyMath" src="www/MyMath.js"><clobbers target="cordova.plugins.MyMath" /></js-module><platform name="android"><config-file parent="/*" target="res/xml/config.xml"><feature name="MyMath"><param name="android-package" value="SimpleMath.MyMath" /></feature></config-file><config-file parent="/*" target="AndroidManifest.xml"></config-file><source-file src="src/android/MyMath.java" **target-dir="src/SimpleMath**" /></platform></plugin>
