Hi,
I'm trying to get an Android app to talk to a native Android binary
service. Basically when I click a button, the app should send data to the
service, and receive some data back as well. I've written the Android
client app code, relevant portion below:
Button.OnClickListener buttonSendOnClickListener = new
Button.OnClickListener(){
//@Override
public void onClick(View arg0) {
Socket socket = null;
DataOutputStream dataOutputStream = null;
DataInputStream dataInputStream = null;
try {
socket = new Socket("10.0.2.2", 8888);
dataOutputStream = new DataOutputStream(socket.getOutputStream());
dataInputStream = new DataInputStream(socket.getInputStream());
dataOutputStream.writeUTF(textOut.getText().toString());
} catch (UnknownHostException e) {
// TODO Auto-generated catch block
e.printStackTrace();
} catch (IOException e) {
// TODO Auto-generated catch block
e.printStackTrace();
}
finally{
if (socket != null){
try {
socket.close();
} catch (IOException e) {
// TODO Auto-generated catch block
e.printStackTrace();
}
}
if (dataOutputStream != null){
try {
dataOutputStream.close();
} catch (IOException e) {
// TODO Auto-generated catch block
e.printStackTrace();
}
}
if (dataInputStream != null){
try {
dataInputStream.close();
} catch (IOException e) {
// TODO Auto-generated catch block
e.printStackTrace();
}
}
}
}};
When I run the app, it hangs and times out when I click the button. Turns
out it hangs on the socket connection. Is this because I have the wrong
address, or because there's no server listening to the same socket?
Also, are there any example code for a server I can cross compile for
Android that will talk to the Android app using sockets?
Thanks!
