Re: [android-beginners] why Java, not Python?
To my knowledge, Java is simply faster. That, and Python is also rather "big". With any luck, Unladen Swallow might find its way onto our devices.. then perhaps we can get Python onto Android. Personally, i would give my right leg for Python on android. (And by that, i mean Python working as well as, or better, than Java. Not that python scripting project, heh.)

[android-beginners] Re: why Java, not Python?
It has to do with how scripted oop languages are implemented..in tis case Python is implemented via C. Most mobile app languages base don C have higher learning curves and break easier..such as Symbian C, and Apple's own Objective C for iPhone.. While the learning curve to python might be lower keeping it somehow working on mobile its a very daunting task Java was originally designed for small devices..

[android-beginners] Custom inputType
I have editText which accepts numeric details with an optional text suffix, (ie. 90.895t). I am using addTextChangedListeners and pattern/match to ensure correct data entry. Planning to call text soft keyboard in number/symbol view initally, with text view obtainable from this keyboard. I have tried inputType variations, with the only suitable view being datetime, this however only allows enrty text entry in the datetime format. As the pre-existing attributes are ignored if inputType has been defined, there is no way of tweaking inputType attributes? Or is there a simpler way of calling up specific soft keyboards (numeric, symbol, text)? -- You received this message because you are subscribed to the Google Groups "Android Beginners" group.

Re: [android-beginners] why Java, not Python?
This is my theory. One of the creators of Android company, which android is based on, came from an company called Danger in mountain view. Danger made the sidekick - The applications made on the sidekick are all done in java. http://developer.danger.com/site/faq/show#q5 An natural evolution of the client side language for android based on the founders experience would be java.

There now seem to be many of us who are experiencing this behaviour. I have an emulator running now which has been running for over 24 hours and still has not displayed the home page.

Generic desktop, P4 machine running Ubuntu 9.04. Emulator boots up in under 2 minutes. -David On Nov 20, 12:46 pm, Justin Anderson wrote: > The emulator takes extremely long to load.

[android-beginners] Launching Raw Contact Picker in Android 2.0

[android-beginners] Beginning to use OpenGL ES on Android
Hello Everyone! The more I study the examples in the ApiDemo folder, the more I'm beginning to understand how everything is meant to work. I do need some minor clarification on something. In the docs there is this quick snippet: "Here's how to use the API at an extremely high level: 1. Write a custom View subclass. 2. Obtain a handle to an OpenGLContext, which provides access to the OpenGL functionality. 3. In your View's onDraw() method, get a handle to a GL object, and use its methods to perform GL operations. For an example of this usage model (based on the classic GL ColorCube), showing how to use it with threads can be found in com.android.samples.graphics.GLSurfaceViewActivity.java." I'm not following how this creates a thread. Reading over thread creation, there's both a Handle and Thread object created... with is not done here. My apologies if this is a bit of an ignorant question, but I'm just as new to Java as I am to Android. (I'm intermediate with C and have used OpenGL). The TriangleActivity.java with the StaticTriangleRenderer.java is a great example to learn from, but I'm still not sure how this makes use of a thread. Or perhaps... is the thread creation handled somehow in the renderer that I'm not following?

[android-beginners] UNIX domain socket used on PhoneFactory.java
Hi,
I am looking on the PhoneFactory.java file and I found the following
code:
try {
// use UNIX domain socket to
// prevent subsequent initialization
new LocalServerSocket
("com.android.internal.telephony");
} catch (java.io.IOException ex) {
hasException = true;
}
I searched through the code looking for some reference to that socket
name but I find nothing.I am not expert with domain sockets but I
found that all I need to do is open a socket connection to the socket
using the domain as reference and you are all set.
Could someone please explain me how this works and where this socket
is actually being used?
Thank you!

[android-beginners] surfaceCreated() and CreateSurface() in camera preview application
I have some questions regarding the code below for camera preview
applicaiton. I am hoping someone can help me out. Thanks in advance.
1. How does surfaceCreated() and CreateSurface() relate? Is this
surface created via createSurface() from SurfaceFlinger client to
SurfaceFlinger server? If so, there must be
2 buffers (frame buffers from display driver if there is hw
acceleration or if it is the emulator, it will be from ashmem)
associated with this surface: surface BB (for composition)
and surface FB (for display). Am I correct? Can you please confirm?
2. How does the rendering buffer (frame buffer BB and frame buffer
FB) get allocated in the camera preview application? Are they
allocated by the application?
3. How does this surface relate to the preview buffers? Are the
preview buffers allocated by the Camera Service during startPreview?
private class CameraSurfaceView extends SurfaceView implements
SurfaceHolder.Callback {
private SurfaceHolder mHolder;
private Camera camera = null;
public CameraSurfaceView(Context context) {
super(context);
mHolder = getHolder();
mHolder.addCallback(this);
mHolder.setType(SurfaceHolder.SURFACE_TYPE_PUSH_BUFFERS);
}
public void surfaceCreated(SurfaceHolder holder) {
camera = Camera.open();
try {
camera.setPreviewDisplay(mHolder);
} catch (Exception e) {
Log.e("Camera", "Failed to set camera preview
display", e);
}
}
}
Thank you very much for your help.

[android-beginners] Network down issue
Hi,
In my application i get response from web service and show its result
from resultant stream at activity, i get stream as
try
{
String connectTo = webService + webServiceMethod + queryString;
connectTo = connectTo.replaceAll(" ", "%20");
URL url = new URL(connectTo);
URLConnection ucon = url.openConnection();
ucon.setConnectTimeout(15000);
ucon.connect();
InputStream is = ucon.getInputStream();
BufferedInputStream bis = new BufferedInputStream(is);
return bis;
}
catch (SocketTimeoutException e)
{
throw e;
}
catch (MalformedURLException e)
{
throw e;
}
catch (IOException e)
{
throw e;
}
If emulator/device is connected with internet then this code work fine
but if i disconnect internet and try to connect any URL then it keep
continue to wait even few minutes, however i set connection timeout 15
seconds. This feel really bad. I want a smart solution, if internet is
down or disconnected this code will throw SocketTimeOut exception or
notify me AFTER 15 seconds that net is down.

[android-beginners] Re: random problem
True. Even then, this is probably not the code he really wants.
Instead of using casts on a Random method returning doubles, he could
use the java.lang.util.Random.nextInt() method to get an integer in
the range he specifies.
Then instead of "(int( (Math.random()*9)+1" he could have, after a
declaration like "Random mRandGen = new Random();",
mRandGen.nextInt(9) +1;
to return a random integer from 1 to 10.
Code w/o casts is generally better than code with casts. Unless, of
course, it resorts to drastic contortions to avoid the case. But such
is not the case here.,

[android-beginners] why Java, not Python?
Not trying to start a flame war here, just curious about the decision to use Java as the main language for Android development instead of Python. For one Python is one of the main languages used by Google, and both languages are byte-code interpreted. Python has a very rich set of libraries which make it easy to do things quite succinctly. For instance if I wanted to know how old a friend's baby exactly is I could do something like: from datetime import datetime start = datetime(2009, 10, 3, 9, 45, 0, 0) age = datetime.now() - start print 'Birthday/time :', start print 'Baby's exact age:', age Perhaps I don't know Java well enough, but this would be much more verbose/complex to do in Java. Again, not trying to start any arguments, just curious if anyone has any background on this.

[android-beginners] Re: Absolutely Infuriating
So how was it that he got this error, and you did not? You did say the API demos all compiled for you "out of the box", didn't you?

[android-beginners] Re: Trouble with updating widgets
Hi, onUpdate will never fire if you are using onReceive at all. If you override onRecieve you have to handle all the messages yourself inside it, include the update message. -niko On Nov 18, 6:03 pm, DMc wrote: > Hello, > > I am trying to create a widget which updates at a user defined period, > following this > tutorial:http://www.developer.com/ws/article.php/10927_3833306_2/Creating-a-Ho... > > All has been going well but I cannot get the onReceive and onUpdate > events to fire on the Provider. > > This is the code to set up my AlarmManager > > Intent widgetUpdate = new Intent(); > > widgetUpdate.setAction > (AppWidgetManager.ACTION_APPWIDGET_UPDATE); > > widgetUpdate.putExtra(AppWidgetManager.EXTRA_APPWIDGET_ID, > appWidgetId ); > > widgetUpdate.setData(Uri.withAppendedPath(Uri.parse > (ProfileDisplayWidgetProvider.URI_SCHEME + "://widget/id/"), > String.valueOf(appWidgetId))); > > PendingIntent newPending = PendingIntent.getBroadcast > (getApplicationContext(), 0, widgetUpdate, > PendingIntent.FLAG_UPDATE_CURRENT); > > AlarmManager alarms = (AlarmManager) getApplicationContext > ().getSystemService(Context.ALARM_SERVICE); > > alarms.setRepeating(AlarmManager.ELAPSED_REALTIME, > SystemClock.elapsedRealtime(), 15 * 1000, newPending); > > If I remove the widgetUpdate.setData() line, then the onReceive event > fires, but not the onUpdate.

[android-beginners] Re: Tab views, onStart() ???
Jason
In my application i hva etwo tabs. One for inttant queue and one for
disc queue(netflix)
as the user presses the tabs (back and forth) the listview on each tab
refreshes.
You can use onTabCHanged to keep control of which tab the user is on,
and call a custom method to re-populate the listview.
I promise you can do this without bothering with any of the higher
activity flow methods (onStart..etc)
public void onTabChanged(String tabId) {
//this may get called when setting up layout, so only
listen if user's session is active
if(sessionStatus==SESSION_ACTIVE){
FlurryAgent.onEvent("onTabChanged");
if (mTabHost.getCurrentTab() == TAB_INSTANT) {
if (canWatchInstant) {
queueType =
NetFlixQueue.QUEUE_TYPE_INSTANT;
loadQueue();
} else {
showCustomDialog(
"Restricted",
"According to
Netflix this user does not have \"Watch Instantly\" rights\nPress
'Back' to return to your Disc Queue");
mTabHost.setCurrentTab
(TAB_DISC);
}
} else if (mTabHost.getCurrentTab() ==
TAB_DISC) {
queueType =
NetFlixQueue.QUEUE_TYPE_DISC;
loadQueue();
}
}
}
/* loadQueue makes an API call to get fresh or cached data, and then
calls redrawQueue to actually repopulate the currently displayed tab.
*/
protected void redrawQueue() {
switch (mTabHost.getCurrentTab()) {
case TAB_DISC:
mListView = (ListView) findViewById
(R.id.discqueue);
mListView.setAdapter(new ArrayAdapter(this,
android.R.layout.simple_list_item_1, NetFlix.discQueue
.getDiscs()));
break;
case TAB_INSTANT:
mListView = (ListView) findViewById
(R.id.instantqueue);
mListView.setAdapter(new ArrayAdapter(this,
android.R.layout.simple_list_item_1, NetFlix.instantQueue
.getDiscs()));
break;
}
mListView.setTextFilterEnabled(true);
mListView.setOnItemClickListener(this);
// register for long hold on menu items
registerForContextMenu(mListView);
}
Enjoy.

[android-beginners] Re: Tab views, onStart() ???
I'm using an activity that extends android.app.Activity for the contents of each tab. Only the activity that hosts the tabs extends android.app.TabActivity. It might be worth checking to make sure that you tested onResume and not onStart. As you can see in the logs above, onStart only gets called the first time you go to a tab that isn't started using FLAG_ACTIVITY_CLEAR_TOP, just like you mentioned seeing.
