How to access data in InputStream as String?

Question

I am trying to create an android client and java server application using socket programming. I need to retrieve the file send from java server but i dont want to write that content into another file in client side. Instead i want to create a listbox with the contents in the received file. I can find code for write these contents in a file but I dont know how to access the contents as strings.

Here is the code i tried:

Android client

client=new Socket("10.0.2.2", 7575);
writer=new PrintWriter(client.getOutputStream(),true);
writer.write(mMsg);
writer.flush();
writer.close();
InputStream is=client.getInputStream(); 
bytesread=is.read(mybytearray,0,mybytearray.length);

I changed my code as follws but it is not working.

 InputStream is=client.getInputStream();
 BufferedReader bf=new BufferedReader(new InputStreamReader(is));
 String value=bf.readLine();

Wrap your inputstream into a BufferedReader

BufferedReader d
          = new BufferedReader(new InputStreamReader(is));

and use readLine() method.

Reads a line of text. A line is considered to be terminated by any one of a line feed ('\n'), a carriage return ('\r'), or a carriage return followed immediately by a linefeed.

Try this:

InputStream is=client.getInputStream(); 
bytesread=is.read(mybytearray,0,mybytearray.length);
// Create a new String out of the bytes read
String data = new String(mybytearray, 0, bytesread, CharSet);

OR

Wrap the InputStream using BufferedReader and read the data line by line (using readLine()) in String format.

@user3243259: Refer this docs.oracle.com/javase/7/docs/api/java/nio/charset/Charset.html. For now you can pass it as "UTF-8"

Using buffered reader is best or you can try the code below:

After the last statement use the byte[] "mybytearray" to convert to string as below:

if(bytesread > 0)
    String result = new String(mybytearray);
