[Q] Coding Problem - CameraApp + Real Device

Hi Guys!
I'm coding a little app, but I don't know what I'm doing wrong.
The App does the following:
- Launches a Service which listens for an sms, then captures a picture with the cam and sends it to a predefined email adress. (no, i'm not trying to spy somebody out... I'm using the app to get a "3G-Webcam", sort of at least)
The problem:
My App works great in the emulator, but as soon as I try it on my HTC Magic (cm6, android 2.2) it stops working.

[Q] How download file in internal storage?

Hello, I want to download a xml file in local storage that I will parse.
The code is this
URL website = new URL("http://juventus.com/rss/news/ita.xml");
ReadableByteChannel rbc = Channels.newChannel(website.openStream());
FileOutputStream fos = new FileOutputStream(c.getFilesDir()+"/eng.xml");
fos.getChannel().transferFrom(rbc, 0, Long.MAX_VALUE);
fos.close();
This is called in doInBackground() of a AsyncTask class.
I get this error:
08-01 22:17:40.061: E/AndroidRuntime(9002): java.lang.RuntimeException: An error occured while executing doInBackground()
08-01 22:17:40.061: E/AndroidRuntime(9002): Caused by: java.lang.IllegalArgumentException: position=0 count=9223372036854775807
08-01 22:17:40.061: E/AndroidRuntime(9002): at java.nio.FileChannelImpl.transferFrom(FileChannelImpl.java:359)
What I do wrong?
I also tried this:
URL website = new URL("http://juventus.com/rss/news/ita.xml");
ReadableByteChannel rbc = Channels.newChannel(website.openStream());
FileOutputStream fos = c.openFileOutput("eng.xml", Context.MODE_PRIVATE);
fos.getChannel().transferFrom(rbc, 0, Long.MAX_VALUE);
fos.close();
Hope you help me.
Thanks!

Try this...
Code:
URLConnection conn;
Log.d(TAG, "onDownload....path is: " + path);
try {
URL url = new URL(path);
conn = url.openConnection();
contentLength = conn.getContentLength();
DataInputStream in = new DataInputStream(conn.getInputStream());
Log.d(TAG, "Buffering the received stream(size=" + contentLength);
if (contentLength != -1) {
buffer = new byte[contentLength];
in.readFully(buffer);
in.close();
}else{
result = false;
return;
}
if (buffer.length > 0) {
Log.d(TAG,
"onDownload. Writing file to files dir,");
DataOutputStream out;
FileOutputStream fos = context.openFileOutput(fileName,
Context.MODE_PRIVATE);
Log.d(TAG, "Writing from buffer to the new file.." + fileName);
out = new DataOutputStream(fos);
out.write(buffer);
out.flush();
out.close();
result = true;
Edit: Here I am returning a boolean to indicate successful download.

GCM Register method failes on device - AUTHENTICATION_FAILED

Hello all,
I am trying to implement Google Cloud Messaging in my app, but I get the error java.io.IOException: AUTHENTICATION_FAILED when I test it on the device. Everything goes well on an Android 4 device, but I have two Android 2.3.3 devices (Samsung Galaxy II) and it fails every time.
From online search I learned that the error is/used to be because of a password problem or having multiple Google account installed. I checked the password and it's correct. It's true that the two devices tested had two Google accounts installed on each, but I uninstalled one and tried again but it failed again.
Anyone has any idea what could cause the problem?
The code that fails:
Code:
GoogleCloudMessaging gcm = GoogleCloudMessaging.getInstance(context);
String regId = null;
try {
[B]regId = gcm.register(params[0]);[/B]
setRegistrationId(context, regId);
sendRegistrationToServer(regId);
} catch (IOException e) {
Log.e(getClass().getSimpleName(), "Registration failed. " + e);
e.printStackTrace();
}
The code is inside an AsyncTask. (Full code:
Code:
static public class BaseRegisterTask extends AsyncTask<String, Void, String> {
protected Context context = null;
BaseRegisterTask(Context context) {
this.context = context;
}
[user=439709]@override[/user]
protected String doInBackground(String... params) {
GoogleCloudMessaging gcm = GoogleCloudMessaging.getInstance(context);
String regId = null;
try {
regId = gcm.register(params[0]);
setRegistrationId(context, regId);
sendRegistrationToServer(regId);
} catch (IOException e) {
Log.e(getClass().getSimpleName(), "Registration failed. " + e);
e.printStackTrace();
}
return regId;
}
protected void sendRegistrationToServer (String regId) {
// OVERRIDE ME
}
protected void onError(IOException e) {
Log.e(getClass().getSimpleName(), "Exception registering for GCM: ", e);
}
}
)
The caller:
Code:
new RegisterTask(getBaseContext()).execute(MESSAGING_SERVER_ID);
@ onCreate of the main activity.
The log:
Code:
10-04 13:25:37.238: E/RegisterTask(4057): Registration failed. java.io.IOException: AUTHENTICATION_FAILED

did you remove the Google account which had Access to the playstore or the other one?

I removed the other one. The device doesn't let me remove the one associated with the Play Store. (The error message says that to do that, one has to perform factory reset...)
I tried switching the Play Store account to the other one, but it still fails with the same error [and the other account is still non-removable.

it tells you there, note that on line 239 you are asking an object (in this case "txtInfromacion") to execute one of it's methods, but the object is actually "null" so it throws the exception
disclaimer, I only looked at it for 10 seconds cause busy but I would think there is a 99.5% chance I'm correct
EDIT : ok looked at it another 5 seconds, you never assign anything to that TextView, like associating it with the view on screen ? eg. findViewById(R.id.someID)
