Android Development : File is probably compressed

this'll be my first post on SO so please be gentle. I'm currently developing an Android app and am attempting to simply read a .txt file in. After many seperate hurdles to overcome (this is my first attempt at reading in a text file) I've come across a rather nasty problem of it throwing the error message This file cannot be opened as a file descriptor; it is probably compressed. ``` assetmgr = thiscontext.getAssets(); try { descriptor = assetmgr.openFd("level1.txt"); } catch (IOException e) { // TODO Auto-generated catch block e.printStackTrace(); } ``` The above piece of code is simply attempting to read in the text file. However, it is returning null to descriptor which is obviously causing errors further down the line. ``` inputStream = new FileReader(descriptor.getFileDescriptor()); ``` This is the line that is initialising the inputstream for parsing the text file in the loop I've created out of this scope. So my problem is how do I fix the txt file not opening correctly and apprarently being compressed. If I have made any errors in posting please let me know so I can correct them to get the best possible advice! Cheers!
