Where to put text files in directory in Android

I have a text file i want to include in my Android application, it is not a string file it is a standard text file. It contains data that defines the characteristics of a "map" that is drawn on a board. The file is not an XML file so i am unsure where i should put it or if this isn't good file structure for android? Are you suppose to do this? If you are then under what directory are you suppose to put them? How then are you suppose to access the file? I know how to use FileInputStreams and FileOutputStreams i just need to know how to access the file. All relevant answers are welcome and appreciated!

I would just like to add to the accepted answer (I don't have enough reputation to comment unfortunately.) The link there to the tutorial that explains how to set up the res/raw method or the assets method is mostly good, but there's actually a MUCH easier way. Look at the function described there called LoadFile. That function is rather verbose. Lets say all you need is an InputStream variable so that you can read and write to a file. Then delete everything after line 77! Also you don't need the resource id at all! You can use this function:

//get the file as a stream
iS = resources.openRawResource(R.raw.mygpslog)

Now all you have to do is return iS and you will have your much desired file handle.

You have to put your file in the assets folder as Waqas said.

Now to access it you do it like that.

I give you an example using BufferedReader

BufferedReader reader = new BufferedReader(
                 new InputStreamReader(getAssets().open("YourTextFile.txt")));

Be careful. In my case, I don't know why for now, I cannot read text files bigger than ~1MB and I had to split them in multiple small files. It seems other had the same problem of file size but I didn't find any information about that on Android developer site. If any one knows more about this ....

FOLLOW UP

My problem with the 1MB was due to a know bug/limitation of earlier versions of Android. Since using recent versions of Android, that problem is not present anymore.
