[android-developers] MapView on 1.6 very strange behaviour
Hi, in my app I display MapViews in several activities. Now that I have updated my G1 device to 1.6, I notice that at some pleace the MapView is displayed properly, and at others - it's not - I can see the my OverlayItem though. I'm 100% I use the same keys throughout my app. Any suggestions as to where it's going wrong?

[android-developers] Handling Network Unavailability
The application I'm working allows a continious upload of several Mbs over http, which turns out to be quite a challenge when testing it on T-Mobile's 3G netowrk in the UK. At points the stream is interrupted and the network status seems to change from connected to idle during data transmission. The tricky part here is that my broadcast receiver does not detect the change, whereas I can clearly see that no data has been uploaded by the indication of the 3G icon in the status bar. Has anyone faced anything similar to that? How do you overcome this issue when your app has established a network connection, but then out of nowhere it losses it, and there is no way for you to detect that... I'm fairly familiar with the architecture of mobile 3G networks, and the principles of connecting to a B-Node and maintaining that connection, however, in my case it seems that the client keeps losing connectivity completely randomely. Any thoughts appreciated thanks! --~--~-~--~~~---~--~~ You received this message because you are subscribed to the Google Groups Android Developers group.

[android-developers] TextView with dyncami links
Hello, I have a TextView containing special pieces of information, which I would like to perform some action on. The closest supported functionality I can think of in android is android.util.text.Linkify, however, I find it limited as it only recognises phone numbers, email, web and map addresses. In my case I would like to parse the text, and make certain parts of it link to other activities for instance. It would be great to get some directions here.

[android-developers] Video Streaming
Hi, I'm trying to stream a video from an HTTP server to my client. In order to play it I fire up an action_view intent by providing to it the uri of the media. The client opens up a new browser window, and then redirects to the youtube player as expected. However, after a couple of seconds it throws a 'Cannot play video' error.

[android-developers] Unlocking screen after wake lock

I've tried broadcasting Intent.ACTION_CLOSE_SYSTEM_DIALOGS, however, that seems not to work. Any ideas of how to fix that?

[android-developers] Advice on debug tool for I/O
Hi, On a number of cases I have experienced problems with server / client communication where the server responses with XML files, which never reach my client. Is there any tool for monitoring everything incoming through an HTTP connection, or if not what is your advice to detect what's come through and what's not. I've tried Charles proxy, which intercepts all requests / responses, however, Android seems to refuse to work with proxies. Any advice will be much appreciated.

[android-developers] Parsing XML feed with SAX
Hi,
I'm unable to consume a WS with the SAX, for some reason my
implementation doesn't read the complete XML feed, it reads it up to a
random point. Has anyone faced anything similiar? Here's what I'm
doing:
After calling a RESTful WS a read the response from the server as
follows:
if (isSessionActive){
HttpEntity entity = response.getEntity();
SAXParserFactory spFactory = SAXParserFactory.newInstance();
SAXParser saxParser = spFactory.newSAXParser();
XMLReader xmlReader = saxParser.getXMLReader();
eventsHandler = new EventsHandler();
xmlReader.setContentHandler(eventsHandler);
xmlReader.parse(new InputSource(entity.getContent()));
}
Where my EventsHandler.java is as follows:
public class EventsHandler extends DefaultHandler {
@Override
public void startDocument() throws SAXException {
}
@Override
public void endDocument() throws SAXException {
}
@Override
public void startElement(String namespaceURI, String localName,
String qName, Attributes atts) throws SAXException {
Log.i(this.toString(), + localName + );
}
@Override
public void endElement(String namespaceURI, String localName, String
qName) throws SAXException{
Log.i(this.toString(), / + localName + );
}
@Override
public void characters(char ch[], int start, int length){
}
}
Hope to get some feedback! Thanks.

[android-developers] Problem with Camera and layout orientation
Hi, I've been trying to solve this for awhile now, and still couldn't find a solution to it. To properly display my SirfaceView consumed by the camera, I have forced my activity's layout in landscape mode. However, in my app the camera functionaluty will be mostly used in portait mode, and therefore all other views in the same activty have to be in portrait mode. Needless to say if I don't force the activity in landscape, the SurfaceView is 90 degrees rotated. Any ideas on how to solve it?

[android-developers] Issue with Threads and onCreate()
Hi, I've faced the following issue. Upon loading my app I have several threads consuming an http output stream to update some state. I've implemented the Handler technique and have my threads posting back when they're ready to do so. This usually takes 2-3 seconds. The issue comes if the keyboard is opened within this period since G1 restarts the onCreate(), and basically repeats the process. So when the first threads are ready to post back they're throwing NullPointerException. The only solution that comes to my mind is to detect when the device is about to force change of portrait to landscape and vice versa, and at this point to stop all threads previously created so my client won't throw the NullPointerException erros. Is this a well know issue with a well known solution? Hope I will get some advice as this problem is ruining my whole app. Thanks! --~--~-~--~~~---~--~~ You received this message because you are subscribed to the Google Groups Android Developers group.

[android-developers] Problem with setText() on custom CheckBox
Hi,
I've implemented a custom CheckBox view and faced a probelm with
adding text to it.
Here's my implementation:
public class MyCheckBox extends CheckBox{
private int imgResourceFocusedChecked, imgResourceFocusedNotChecked,
imgResourceNotFocusedChecked, imgResourceNotFocusedNotChecked;
public MyCheckBox(Context context){
super(context);
}
public MyCheckBox(Context context, AttributeSet attrs) {
super(context, attrs);
init(attrs);
}
public MyCheckBox(Context context, AttributeSet attrs, int defStyle)
{
super(context, attrs, defStyle);
init(attrs);
}
private void init(AttributeSet attrs){
TypedArray a = getContext().obtainStyledAttributes(attrs,
R.styleable.MyCheckBox);
imgResourceFocusedChecked = a.getResourceId
(R.styleable.MyCheckBox_checkboxFocusedChecked, -1);
imgResourceFocusedNotChecked = a.getResourceId
(R.styleable.MyCheckBox_checkboxFocusedNotChecked, -1);
imgResourceNotFocusedChecked = a.getResourceId
(R.styleable.MyCheckBox_checkboxNotFocusedChecked, -1);
imgResourceNotFocusedNotChecked = a.getResourceId
(R.styleable.MyCheckBox_checkboxNotFocusedNotChecked, -1);
strResourceText = a.getResourceId
(R.styleable.MyCheckBox_checkboxText, -1);
}
public void onDraw(Canvas canvas){
if (this.isChecked()){
if (this.isFocused()){
this.setBackgroundResource(imgResourceFocusedChecked);
} else {
this.setBackgroundResource(imgResourceNotFocusedChecked);
}
} else {
if (this.isFocused()){
this.setBackgroundResource(imgResourceFocusedNotChecked);
} else {
this.setBackgroundResource(imgResourceNotFocusedNotChecked);
}
}
}
}
Then from my layout xml I do something like:
MyCheckBox
android:id=@+id/checkBox
android:layout_width=32px
android:layout_height=32px
android:text=This is a check box.
cb:checkboxFocusedChecked=@drawable/cb_focused_checked
cb:checkboxFocusedNotChecked=@drawable/cb_focused_not_checked
cb:checkboxNotFocusedChecked=@drawable/cb_not_focused_checked
cb:checkboxNotFocusedNotChecked=@drawable/
cb_not_focused_not_checked
style=@style/myStyle/
However, the text never comes up. Using the same technique with Button
and EditText views works fine , but not with check boxes. Hope to get
an advice of how to implement the proper behaviour. Thanks!

[android-developers] ViewGroup, Views and Animation
Hi, I have a few views and animations and I need to figure out a way to package them so I can use them throughout my app. I thought I should be able to use ViewGroup, however, things are getting a bit complicated as my animations need to repeat and to achieve that I have applied the technique with an AnimationListener posting to a Runnable when the animation stops so it plays again in a loop. Also they all have different startOffset values, and I'm not sure how a ViewGroup can handle that as well. What is the best practice for hadnling multiple views and animations?

Hi, I am doing this using the following method:
- Declare int constants which will be unique to each button
- After initializing button variables via findViewById, use
View#setTag to set the unique ID to that button, and the
onClickListener to 'this'
- Declare another int variable which will hold the current state
(mState in the example below)
- Implement the OnClickListener method in the following way:
Integer id = (Integer) view.getTag();
mState = id;
switch (id) {
case BUTTON_1:
//do stuff
break;
case BUTTON_2:
//do more stuff
break;
}
- Create the menu as normal in onCreateMenuOptions
- In onPrepareMenuOptions (which is called each time the menu will be
shown), do something like this:
switch (mState) {
case BUTTON_1:
//hide/show certain menu groups/items
break;
//etc, etc
}
Hope this helps.

[android-developers] onSaveInstanceState(Bundle) onRestoreInstanceState(Bundle)
Hi,
This one is easy, but I seem to have a problem using this technique to
save some state.
Basically, the problem I'm having is that neither
onRestoreInstanceState(Bundle) nor onCreate(Bundle) have the bundle
I've previosly saved from onSaveInstanceState(Bundle). In fact,
onRestoreInstanceState(Bundle) never gets called. Here's my
implementation:
@Override
protected void onSaveInstanceState(Bundle savedInstanceState){
Log.i(MyActivity.class, onSaveInstanceState());
savedInstanceState.putString(MyString, This is a test
message.);
super.onSaveInstanceState(savedInstanceState);
}
Then I fire up another activity, which has a link to the original one,
where I try to recover the state as follows:
@Override
protected void onCreate(Bundle savedInstanceState) {
Log.i(MyActivity.class, onCreate());
if (savedInstanceState != null){
String myString = savedInstanceState.getString(MyString);
Log.i(AddActivity.class, myString);
}
}
@Override
protected void onRestoreInstanceState(Bundle savedInstanceState){
Log.i(AddActivity.class, onRestoreInstanceState());
super.onSaveInstanceState(savedInstanceState);
String myString = savedInstanceState.getString(MyString);
Log.i(AddActivity.class, myString);
}
Like I said the onRestoreInstanceState(Bundle) method doesn't even get
called.
Has anyone faced the same problem? How did you resolve it? Thanks.

[android-developers] Camera Focus Facility
Hi, My app is struggling to take focused shots. Is there a built in facility that sets an auto-focus property on the camera, so it automatically takes clear and focused images. I've noticed that feature in numerous well-known apps such as ShopSavvy, CompareEverywhere, etc. Could you advise on how to achieve that?

[android-developers] Re: SAXParser doesn't resolve Entitiy-References ( EntityResolver )
Hi,
The implementation of SAXParser seems to encounter problems when it
attempts to parse anything with ''.
Have a look at those threads, if you haven't done so already:
http://groups.google.com/group/android-developers/browse_thread/thread/f9a1ce37af6db350/f965528dec77c569#f965528dec77c569
http://groups.google.com/group/android-developers/browse_thread/thread/561e9edee072a175#
If you manage to get the correct value, pls update the thread!

Hi all,

stop_time=2009-01-16T21:57:32+0 factor=rtm31_4;
in startElement(...) attributes correctly indicates the existence of 6
elements
I can get all attributes using i.e. final String startTime =
attributes.getValue(, start_time);
except the last one ( factor=rtm31_4; )
Where:
attributes.getValue(factor);
// or
attributes.getValue(, factor);
always returns (empty string)
it seems like the Entity-Reference is not being resolved =(
If I set an EntityResolver:
myXMLReader.setEntityResolver(new EntityResolver(){
public InputSource resolveEntity(...) {
}}
It NEVER gets called :(
The same code worked in Desktop-Java, all Entities were resolved via
the EntityResolver.
Any ideas? I've spent half a day on this issue alreade =(

[android-developers] Post Bitmap over Http
Hi,
I need to send a bitmap to a server. I've written some code, however,
I got stuck on the part where I need to transform my bitmap into byte
[]. Here is my code:
public void updateBitmap(Bitmap bm){
URL url = null;
HttpURLConnection conn = null;
try {
url = new URL(http://www.myurl.com?;);
} catch (MalformedURLException e) {
e.printStackTrace();
}
try {
conn = (HttpURLConnection) url.openConnection
();
} catch (IOException e) {
e.printStackTrace();
}
try {
conn.setRequestMethod(POST);
} catch (ProtocolException e) {
e.printStackTrace();
}
conn.setDoOutput(true);
conn.setDoInput(true);
conn.addRequestProperty(user_id, user.getUsername
());
conn.addRequestProperty(pass, user.getPassword());
conn.addRequestProperty(id, pinId);
OutputStream os = null;
try {
os = conn.getOutputStream();
} catch (IOException e) {
e.printStackTrace();
}
// Encode bitmap and flush the os
}
Could you advice me on how to complete my code? Thank you.

[android-developers] Re: Post Bitmap over Http
Hi, I added the following code, however, I got an OutOfMemoryError. It
comes from the bos.flush() line... Am I doing it wrong? I
BufferedOutputStream bos = new BufferedOutputStream(os);
bm.compress(CompressFormat.JPEG, 100, bos);
try {
bos.flush();
bos.close();
os.close();
} catch (IOException e) {
e.printStackTrace();
}
conn.disconnect();
Thank you!
bm.compress(CompressFormat.PNG, 100, os);
Note that PNG is lossless and will ignore the 2nd argument.
Now, the API *could* have a helper method called save(CompressFormat,
Stream) passing the max quality as a default 2nd parameter but that's
another story...
Cheers,
Stoyan

You haven't really given enough information for a definitive answer. Are you
calling the following somewhere?

But, I would also put an if (b != null) in as the third line to stop the

Can you post your Stack trace or logcat? It should have enough information
to figure out what the problem is.

[android-developers] Re: GetLastKnownLocation vs. requestLocationUpdates
Unfortunately, JSR-179 is not part of Android. I mentioned it filled with nostalgic for the old days of Java ME when JSR-179 was the the best alternative to build LBS apps. Having looked at the android.location pack, the best way to find the current location seems to me like that: 1. Call LocationManager.requestLocationUpdates() 2. Then in your LocationListener implementation, you would get the new Location object in the onLocationChanged() method everytime your pre- specified criteria are met. 3. So if you are only interested in your current location, you would call LocationManager.removeUpdates() from onLocationChanged(), and do whatever you want with the Location object.

[android-developers] Re: GetLastKnownLocation vs. requestLocationUpdates
I think the API doc is explanatory enough. public Location getLastKnownLocation(String provider) Returns a Location indicating the data from the last known location fix obtained from the given provider. This can be done without starting the provider. Note that this location could be out-of-date, for example if the device was turned off and moved to another location. You get accurate coordinates only if the location provider has been active. Otherwise, as you move, and the loc provider is off, nothing will register the location change. You can still make a call for last known location but it will be inaccurate. I'm a little disappointed by the LBS API Google has delivered this time. I find JSR-179 a way better in most situations.
