I have not suffer this problem with 22.6 but with 23. In my case, the problem seems to be the free maker sintax of the .flt files of the template.
Just in case this could be useful to others, I've solved this issue changing two files:
$ANDROID_SDK/tools/templates/activities/BlankActivity/recipe.xml.ftl original:
<?xml version="1.0"?>
<recipe>
<#if appCompat><dependency mavenUrl="com.android.support:appcompat-v7:19.+"/></#if>
...
I've added ?has_content after <#if appCompat in line 4:
<?xml version="1.0"?>
<recipe>
<#if appCompat?has_content><dependency mavenUrl="com.android.support:appcompat-v7:19.+"/></#if>
...
The other file is $ANDROID_SDK/tools/templates/activities/BlankActivity/root/res/menu/main.xml.ftl. The original version starts with:
<menu xmlns:android="http://schemas.android.com/apk/res/android"<#if appCompat>
...
I've added the same string at the end:
<menu xmlns:android="http://schemas.android.com/apk/res/android"<#if appCompat?has_content>
...
The same errors exist in many other activities templates...
Keep in mind that these changes will be overwriten with the next SDK update... I hope Google solve this issue, because developping for Android with Eclipse is becoming a headache.
