I have some code to download an XML file that has been shipping in a paid app for a few years - never had any trouble until I recently saw this happen with an HTC One.
Wondering if there is something I am missing or if this should get reported somewhere.
Here is example code that forces the issue:
package com.lutron.davetest;
import java.io.BufferedInputStream;
import java.io.InputStream;
import java.net.URL;
import java.net.URLConnection;
import android.os.AsyncTask;
import android.os.Bundle;
import android.app.Activity;
import android.app.AlertDialog;
import android.content.DialogInterface;
import android.content.DialogInterface.OnClickListener;
import android.view.Menu;
import android.widget.EditText;
import android.widget.TextView;
public class MainActivity extends Activity {
private TextView mainCenterText;
@Override
protected void onCreate(Bundle savedInstanceState) {
super.onCreate(savedInstanceState);
setContentView(R.layout.activity_main);
mainCenterText = (TextView) findViewById(R.id.mainCenterText);
AlertDialog.Builder builder = new AlertDialog.Builder(this);
builder.setTitle("Enter the IP address");
final EditText edit = new EditText(this);
builder.setView(edit);
builder.setPositiveButton("OK", new OnClickListener() {
@Override
public void onClick(DialogInterface dialog, int which) {
mainCenterText.setText("");
String ip = edit.getText().toString();
new DownloadTask().execute(ip);
}
});
builder.create().show();
}
private class DownloadTask extends AsyncTask<String, Void, Void>{
@Override
protected Void doInBackground(String... params) {
try{
URL url = new URL("http", params[0], 80, "/file.xml");
URLConnection connection = url.openConnection();
InputStream in = new BufferedInputStream(connection.getInputStream());
byte buf[] = new byte[4096];
int len;
while((len = in.read(buf)) != -1 ) {
final String data = new String(buf, 0, len);
runOnUiThread(new Runnable() {
@Override
public void run() {
mainCenterText.append(data);
}
});
}
}catch(Exception e){
e.printStackTrace();
}
return null;
}
}
@Override
public boolean onCreateOptionsMenu(Menu menu) {
getMenuInflater().inflate(R.menu.main, menu);
return true;
}
}
What happens is that on every other device when reading from the stream you only get the file contents.
On the HTC One you get THIS and then the file contents:
onnection: close
Last-Modified: ???
Content-Type: text/html
This is with Android 4.1.2.
Is there some way to configure the URLConnection to avoid this?
