You can put the file in your assets folder and then open it to read like you would in any other Java program.

Example here.

try { InputStream raw = cntxt.getAssets().open("hello.text"); Reader is = new BufferedReader(new InputStreamReader(raw, "UTF8")); fileContent = is.toString(); }catch(IOException e) { e.printStackTrace(); } i wrote the above piece of code in the constructor of my .java file (the class that is extending Activity) it did nt give any compile error but as soon as i try to open the app on my emulator it crashes it shows app has stopped unexpectedly. why so?? is there anthyng wic is nt defined smwhr n is null??

try { InputStream raw = cntxt.getAssets().open("hello.text"); Reader is = new BufferedReader(new InputStreamReader(raw, "UTF8")); fileContent = is.toString(); }catch(IOException e) { e.printStackTrace(); }
