Same problem, this is the program log:

Result:

AndroidManifest.zip

Should be fixed now;

java -jar build/libs/axmlprinter-0.1.7.jar AndroidManifest.xml | head
<?xml version="1.0" encoding="utf-8"?>
<manifest
	xmlns:android="http://schemas.android.com/apk/res/android"

	manifest:compileSdkVersionCodename="14"

This is mostly fixed, however there is still some oddness on some packers which could still be fixed. See the unit test for this issue and it's clear what needs to be fixed.

However, the axml will get printed out now, mostly correct.

This is actually fully fixed now, it won't be "mostly" correct but actually fully correct now.
