android: how to load xml file from assets directory?

Question

i have trouble loading an xml file from assets directory. using the same line of code (just changing the path) i get different results ( either ok or NPE / file corrupted ) the file "castle1.tmx" (it's an xml file) is copied in two locations:

• res/xml/castle1.tmx
• assets/level/castle1.tmx

with this line, it works:

XmlResourceParser xrp = ctx.getAssets().openXmlResourceParser("res/xml/castle1.tmx");

while with this line it doesn't:

XmlResourceParser xrp = ctx.getAssets().openXmlResourceParser("assets/level/castle1.tmx");

i get the following result:

04-05 21:46:40.940: WARN/ResourceType(29056): Bad XML block: header size 28024 or total size 1702240364 is larger than data size 70441

04-05 21:46:40.944: WARN/System.err(29056):     at game.test.MapLoader.<init>(MapLoader.java:73)

file is found in both case... it's just that i cannot seem to be able to read it from asset dir using that method..

any ideas how can i load my xml file from assets directory ?

tnx

In res/ folder all xml files are precompiled, whereas in assets/ folder they are not. So, you can't use openXmlResourceParser() with non-precompiled resources. Instead use open() and read file through InputStream.
