IndexOutOfBoundException while writing to a file

I'm using this code to write to a file , and it throws IndexOutOfBoundException.

InputStream is = res.openStream();
FileOutputStream fos = new FileOutputStream(file);
byte[] array = new byte[1024];
for(int i = is.read(array); i != 1; i=is.read(array)) {
        fos.write(array, 0, i);
}

how can I check how many bytes left to write?

When there is nothing to read, the read method returns -1 and not 1. Therefore the check in your loop must be:

for(int i = is.read(array); i != -1; i=is.read(array))
