Android SDK since release of API v. 11 contains XmlAdapter sample which is also referenced from the official site. This sample appears now in at least 3 folders: android-11, android-12 and android-13. And it is broken. The main (but not only) problem it declares android.content.XmlDocumentProvider provider which is nowhere to be found including https://android.googlesource.com
There are also compilation problems in Adapters.java:
mContext cannot be resolved to a variable line 973
mFrom cannot be resolved to a variable line 938
mTo cannot be resolved to a variable line 937
mTo cannot be resolved to a variable line 939
There are few question related to this on android-developers but no answer. Did anyone managed to track this elusive XmlDocumentProvider and make the sample work?
And most importantly - dear Android team, can you ether fix the sample or pull it out?
The missing XmlDocumentProvider is now shipping with the sample in SDK 14 and the project compiles against SDK 8 and above. To run it successfully however, you must modify the manifest to point to the correct provider:
<provider android:name="com.example.android.xmladapters.XmlDocumentProvider"
android:authorities="xmldocument" />
