I'm trying to read a response from a server and
BufferedReader.readline will block and never return.
If I run the exact same code from the command line on my Linux host it
works, but it will hang when run on my emulator or device.
Here's the code
try {
System.out.println("will call socket!");
mysocket = new Socket(hostname, portno);
System.out.println("Connected to " +
mysocket.getInetAddress() + " on port "
+ mysocket.getPort() + " from port " +
mysocket.getLocalPort() + " of "
+ mysocket.getLocalAddress());
DataOutputStream os = new
DataOutputStream(mysocket.getOutputStream());
DataInputStream is = new
DataInputStream(mysocket.getInputStream());
BufferedReader d = new BufferedReader(new
InputStreamReader(is));
if (mysocket != null && os != null && is != null) {
os.writeBytes(command + "\r\n");
String line;
System.out.println("calling readline after command:" + command);
line = d.readLine();
System.out.println("got: " + line);
return line;
}
}
catch (UnknownHostException e) {
...
What I see on android is:
I/System.out( 644): will call socket!
I/System.out( 644): Connected to /192.168.1.109 on port 4998 from
port 52695 of /10.0.2.15
I/global ( 644): Default buffer size used in BufferedReader
constructor. It would be better to be explicit if an 8k-char buffer is
required.
I/System.out( 644): calling readline after command:getversion
D/dalvikvm( 98): GC freed 2313 objects / 133904 bytes in 67ms
W/KeyCharacterMap( 644): No keyboard for id 0
W/KeyCharacterMap( 644): Using default keymap: /system/usr/keychars/
qwerty.kcm.
On Linux (OpenJDK) I get what I expect:
Connected to /192.168.1.109 on port 4998 from port 33097 of /
192.168.1.104
calling readline after command:getversion
got: 710-1001-04
getversion returned: 710-1001-04
Any ideas? Is the BufferedReader different on Android?
