I've copied an XML file from /assets to my applications data folder (data/data/package.name/files/). I'm doing this because the user will be able to modify a lot of data, and I want to save that data to the internal memory and then load it again when they restart the app. This all works well, using Root Browser I can see the XML file is properly copied to the data directory.
Now I need to inflate this XML file using a LayoutInflater. How would I access this file? With an XmlResourceParser or XmlPullParser?
You cannot inflate that file using LayoutInflater. First, you can only inflate layout resources, not arbitrary files. Second, based on the description in your first paragraph, it is not a layout file in the first place.
If you want to parse arbitrary XML, use the DOM, SAX, or XmlPullParser.
From the Android view API:
it is not currently possible to use LayoutInflater with an XmlPullParser over a plain XML file at runtime.
A solution might be to pre-process XML files before. You must compress the XML file in the same way the Android SDK does at build time:
view inflation relies heavily on pre-processing of XML files that is done at build time
I guess you will have to call XmlPullParser.setInput to load your pre-processed XML, and then pass the XmlPullParser to View.inflate. I hope it is possible to do this kind of stuff even for content that is not in the APK.
I am very interested in any solution you can find. Please let me know if you find or create a prototype! This would be a decisive step towards creating a plugin architecture for my Open Source app.
