Hi all,
I'm currently trying to get an Android application to connect and send
a protocol buffer to a servlet on App Engine.
However, when I get to the line "OutputStream out =
urlc.getOutputStream()" I get the exception that it "does not support
output."
I've not found many people with this issue, and no posted fixes apart
from using newer SDKs. However, this is for a university project and
I'm sticking to 1.5, so any help would be appreciated.
The only other relevant information I can think of is I have added the
uses internet permission, again I'm on SDK1.5 and I'm running in
Eclipse.
The code is as follows:
package my.transferclient;
import java.io.BufferedReader;
import java.io.InputStreamReader;
import java.io.OutputStream;
import java.net.URL;
import java.net.URLConnection;
import my.tft.protos.RandomMessageProtos.Note;
import my.tft.protos.RandomMessageProtos.RandomMessage;
import android.app.Activity;
import android.os.Bundle;
import android.util.Log;
public class TransferClient extends Activity {
private final static String TAG = "TransferClient";
/** Called when the activity is first created. */
@Override
public void onCreate(Bundle savedInstanceState) {
super.onCreate(savedInstanceState);
setContentView(R.layout.main);
try {
URL url = new URL("http://10.0.2.2:8080/testfileupload";);
URLConnection urlc = url.openConnection();
OutputStream out = urlc.getOutputStream();
RandomMessage.Builder rm = RandomMessage.newBuilder();
Note.Builder note = Note.newBuilder();
note.setName("Blargy McBlarg");
note.setMessage("This is a random message");
rm.addNote(note);
rm.build().writeTo(out);
out.close();
BufferedReader rd = new BufferedReader(new InputStreamReader
(urlc
.getInputStream()));
String line;
System.out.println("Respose is:");
while ((line = rd.readLine()) != null) {
System.out.println(line);
}
rd.close();
} catch (Exception e) {
Log.v(TAG, e.getMessage());
} // catch
}
}
