In the while loop you read the file contents line by line. In each iteration you save the currently read line in the variable text and overwriting the previous content. So you could either directly output the read line or append the read content to the text variable.

I tried both solutions

while(inStream.available()>0) {
          text = reader2.readLine();
            System.out.println(text);
        }

and

while(inStream.available()>0) {
          text += reader2.readLine();

        }
        System.out.print(text);

i get the same error message of too few lines

The first solution should work, the second... when I have another look at it can't work as the reader removes the linebreak and that's missing at the end. Maybe try another approach and just use the FileInputStream without the BufferedReader. I had a look what I did and that was my solution.
