Re: [android-developers] Re: What is the name of this widget?

[Kostya Vasilyev]

I believe the screenshot comes from an HTC device.

If so, then the widget and the application using it are part of HTC 
Sense UI (I'm too lazy to go look at my Hero right now to check). They 
do a lot of custom things in Sense, like scrolling and re-configurable 
widgets.


And while owners of HTC phones would like to see other applications 
looking like Sense, owners of other brands of phones might actually not 
want the HTC look.


Speaking for myself - I now prefer plain Android 2.1 on my Motorola 
Milestone to heavily customized 2.1 on HTC Hero. Looked at an HTC Desire 
HD in a store yesterday, and Sense is even more complex and in-your-face 
there, so I will not be buying that phone just for that reason alone.


( guess I'm more of a "vi" than an "emacs" kind of guy :) )

Thank you for the help, the proposed widget looks good.

metal mikey, I am interested not in date/time entering, but in a way 
to enter numbers - something like the NumberPicker, which seems to be 
internal, and for the means I need it - the wheel looks cooler.


Having this in mind and since while browsing group I see that 
framework engineers are quite active, I would like to share my first 
impression as complete Android developer newbie - I LOVE the platform 
as a user, however as developer I see some strange things - like 
really useful components staying internal for ages (like 
https://groups.google.com/forum/?fromgroups&pli=1#!searchin/android-developers/numberpicker/android-developers/ZdqYIJmP3ck/SXmDORRPE1QJ 
and several more topics about the NumberPicker), now this wheel thing 
not even in platform, but I see it on my phone?


Keeping widgets public would result in cooler applications, boosting 
the interest to the platform even further. Do not make us 
copy/duplicate everything and reinvent the wheel :)

If you could also make NumberPicker public during the overhaul that

[android-developers] Re: Change the background of an AppWidget

[mort]

I think if you're feeling masochistic, you could create 9 images and
do some kind of "manual 9-patch image" with e.g. table or linear
layout views. Just like in bad old HTML times... ;)
If your "dynamically created" images aren't too complex, you might
also use something similar to the XML shape drawables. Opposed to 9-
patch drawables, XML drawables always were scaled correctly if I set
them with setImageViewResource. Maybe it works likewise if you create
a Drawable object like GradientDrawable dynamically?

Re: [android-developers] Re: RPC service with notification

[Kostya Vasilyev]

Jackie,

I already gave you one suggestion, it had to do with 
"AndroidServiceImpl.class".


Here is another:

If inner classes are a new thing to you, don't use one, they can be 
confusing at first.


Make a method in your Service class proper, call it from inside 
AndroidServiceImpl, and then you're back inside your service class, and 
on sample code territory.


Also, using a non-static inner class for the binder (like you are doing) 
causes a memory leak. Here is someone's very nice blog post explaining 
why this happens and what to do about it:

Thanks so much for taking so much time to try and help me out. Here is
how I create the Notification

private Notification notification;
private static final int NOTIFICATION_ID=1;
protected Context context;
@Override
public IBinder onBind(Intent arg0) {
// TODO Auto-generated method stub
return new AndroidServiceImpl();
}
@Override
public void onCreate(){
super.onCreate();
NotificationManager currentManager = (NotificationManager)
getSystemService(Context.NOTIFICATION_SERVICE);

I think the real problem is with the context in the Impl. Can I even
get an application context from the impl? Should this be passed to the
service from the application? Can it be grabed from AndroidService?

public class AndroidServiceImpl extends IAndroidService.Stub{
public String getAndroidText(String conversation)
throws RemoteException {
// TODO Auto-generated method stub
NotificationManager currentManager = 
(NotificationManager)
getSystemService(Context.NOTIFICATION_SERVICE);

Context context = getApplicationContext();

This is for an open source class I am teaching so I can create a
Google project tomorrow if you still want to help. That way you can
see the whole code.

It should be something like:

Re: [android-developers] Re: What is the name of this widget?

[MerlinBG]

Yes, you are right, it is from HTC Desire.

First thought that Sense adds some kind of skin over the NumberPicker, but 
this seems not to be the case when I duplicated it... or perhaps I miss 
something, I am still newbie with Android.
Well, I guess the general feeling is up to the user, I personally like Sense 
a lot.
However, generic things like the NumberPicker should be public, imo.

[android-developers] Re: What's new in honeycomb?

[mort]

I don't know if I get a bit off-topic, but it's still related to
Honeycomb and tablets:
I've seen several apps in the Honeycomb videos which displayed in one
screen what must've been multiple Activities before, like e.g. the
mail list and single mail view.
Will there be an easy way to support multiple visible "Activities", or
is it just hard work to create mightier "Widgets" (e.g. something like
the mail list as Widget instead of ListActivity) and lots of "if that
Widget exists in the current layout ..."?
I think it'd be a good idea to give developers some chance to prepare
for things like that. Properly supporting tablets is more than just
supporting a different screen size, it's often a completely different
UI that must be supported in the same app...
Also, can you give some hints how the future way is planned? Will
there be a Honeycomb for smartphones with a different UI? Will tablet
and smartphone APIs remain compatible? (You know the problem with the
bad long "f" word... ;))

[android-developers] Custom Attributes - Accessing via Activity

[Adam Goodchild]

Hey,

Ive been looking into getting Custom Attributes working within an
application. I have this working up to the point where I am able to
assign the custom attribute via XML to one of my Views (a Background
or Image Source for example).

What I now want to do is access the Custom Attributes via Code, within
my Activity. I am not implementing custom Views here. I am just
wanting to access, within my Activity, the custom attributes that I
have defined. I will use these to programatically change the look of
my List View based on certain criteria.

Is there a way I can do this? I have the following code, but it does
not work, returns null each time. The code is just a test to assign a
background of the splash programatically.

@Override
public void onCreate(Bundle icicle) {
 super.onCreate(

 setContentView(R.layout.splash);

 TypedArray a =
getApplicationContext().obtainStyledAttributes(R.styleable.MainSplash);
 int i =
a.getResourceId(R.styleable.MainSplash_splashDrawable, 0);
 }

I always get returned '0' when using the above code. Any ideas?

[android-developers] Re: Custom Attributes - Accessing via Activity

[Adam Goodchild]

Ok, I have the following files: attrs.xml, styles.xml, themes.xml
Here is my attrs.xml file:








Here is my themes.xml file:


@drawable/splash


Here is my styles.xml file:


?attr/myMainSplashImage


I have looked at different tutorials and libraries (GreenDroid) to
implement the above.
So I have basically set my custom attribute to whatever I have defined
in my Theme file. This allows me to create different theme files for
different projects (as this is a library project).

I have assigned the Theme to the entire library project. I dont know
if I now have to assign something else to my splash layout file?

Another question is relative at how the native heap memory is

Sri,

Its is due to the path problems in Eclipse please correct them. Also when you 
build the whole source (in linux), the build should go through.

If your are enabling launcher2 in Eclair, you need to enable the 
RenderScript(librs.so) library in Framework as well.

Please follow the below steps:

1. Edit Android.mk in frameworks/base/graphics/jni, 
Comment out the line line 41 (add # in the beginning)
#LOCAL_MODULE_TAGS := optional

2. Edit Android.mk in frameworks/base/libs/rs,
Comment out the line line 106
#LOCAL_MODULE_TAGS := optional

3. Then issue "make" (better "make clean") in the eclair directory.

HTH,
Sunil

[Kostya Vasilyev]

Adam,

I am not sure about the extra indirection level you have in your code 
(the "?attr" stuff), but this should work:








@drawable/splash



With this in the manifest:





And then:

TypedArray a = 
this.obtainStyledAttributes(R.styleable.MainSplash);


Drawable d1 = 
a.getDrawable(R.styleable.MainSplash_splashDrawable);


a.recycle();


BTW, you can put all this xml stuff in one file - the name doesn't 
matter, as long as it's inside res/values.

Ok, I have the following files: attrs.xml, styles.xml, themes.xml

Here is my themes.xml file:

 
@drawable/splash


Here is my styles.xml file:

 
?attr/myMainSplashImage


I have looked at different tutorials and libraries (GreenDroid) to
implement the above.
So I have basically set my custom attribute to whatever I have defined
in my Theme file. This allows me to create different theme files for
different projects (as this is a library project).

I have assigned the Theme to the entire library project. I dont know
if I now have to assign something else to my splash layout file?

Where and how are you setting attribute values?

Your call to getStylableAttributes is looking for attribute values in
the activity's theme, is that where you've specified your values?

Hey,
Ive been looking into getting Custom Attributes working within an
application. I have this working up to the point where I am able to
assign the custom attribute via XML to one of my Views (a Background
or Image Source for example).
What I now want to do is access the Custom Attributes via Code, within
my Activity. I am not implementing custom Views here. I am just
wanting to access, within my Activity, the custom attributes that I
have defined. I will use these to programatically change the look of
my List View based on certain criteria.
Is there a way I can do this? I have the following code, but it does
not work, returns null each time. The code is just a test to assign a
background of the splash programatically.
  @Override
  public void onCreate(Bundle icicle) {
   super.onCreate(
   setContentView(R.layout.splash);
   TypedArray a =
getApplicationContext().obtainStyledAttributes(R.styleable.MainSplash);
   int i =
a.getResourceId(R.styleable.MainSplash_splashDrawable, 0);
   }
I always get returned '0' when using the above code. Any ideas?

And then if you have a Service component, be prepared for it to stop

[android-developers] WebView image source

[Neilz]

Hi all.

I have a WebView where I embed an image in the HTML:

pageContent += "";

However I already have the image cached in memory, which can be called
via a static method to return a Bitmap.

Is there a way I can call the cached Bitmap to go in the 'src' tag?
The method getImage currently returns the full URL of the image.

Thanks.

[android-developers] Help with Content Providers / Content Resolvers

[Pedro Duque]

Hi,

I'm developing an editor for my application data. This application has a
free and a premium version, so each one has it's own content provider with
different authorities to avoid clashes. The editor also have a local content
provider so it can work standalone.

What I want to do is to check for a content provider existence when I start
the editor so I can choose to use the local one, the one from the free
application or the one from the premium application. I've search the
documentation but I can't find a way to list the content providers
available, for ex., for a specific MIME type.

Can somebody help me?

Regards,
PMD

[android-developers] Re: Picture orientation from gallery or camera intent

[Juhani Lehtim?ki]

This is turning out to be very difficult problem. I found a solution to one 
part of my problem by reading Android's gallery app's source. When I get the 
picture from gallery it works. This is a code snippet from my 
onActivityResult()

final Uri imageUri = data.getData();

String[] columns = {MediaStore.Images.Media.DATA, 
MediaStore.Images.Media.ORIENTATION};

Cursor cursor = getContentResolver().query(imageUri, 
columns, null, null, null);


if (cursor == null) {

return;
}

cursor.moveToFirst();

int columnIndex = cursor.getColumnIndex(columns[0]);
int orientationColumnIndex = 
cursor.getColumnIndex(columns[1]);


String filePath = cursor.getString(columnIndex);
int orientation = cursor.getInt(orientationColumnIndex);

Log.d(TAG, "got image orientation "+orientation);

This works and I get correct orientation information on phones that don't 
rotate the image automatically.


However! This approach does not work when I get the image directly from 
camera intent. I can still run the same query with the camera intent uri but 
the orientation column is always 0 regardless of the orientation. 
Do someone know how I could get the image orientation from camera intent? 

Any help very much appreciated! Thank you.

Re: [android-developers] Help with Content Providers / Content Resolvers

[Kostya Vasilyev]

The mime type mapping works in the other direction: once you have a 
ContentProvider (or more specifically, a URI for a data query) it can be 
used to get the mime type.


For your task, take a look at:

http://developer.android.com/reference/android/content/pm/PackageManager.html#queryContentProviders(java.lang.String, 
int, int)


If both lite / pro versions share the same user id, you can try using 
that for the first parameter. If not, just filter the results by 
authority (since you know what you expect).


You can also use:

http://developer.android.com/reference/android/content/pm/PackageManager.html#getProviderInfo(android.content.ComponentName, 
int)


by calling it with the lite / pro authorities and checking the return value.

[android-developers] does a handler prevents memory leaks???

[Shawn Brown]

Hi,

Android docs(1) suggest using threads and a handler to send messages
(to avoid ANR).

Fine.  I've always done that but then porting some code to Android
noticed that it's not necessary.

Passing the Activity (i.e. Context) works fine.

public class WorkerThread extends Thread {

private Activity mActivity;

public WorkerThread(Activity mActivity) {
super();
this.mActivity = mActivity;
}

 @Override
public void run() {
  mActivity.showToast("WorkerThread thread says hello");  //
displays a message
  //setting a TextView works fine too
...
}

I understand the potential for memory leaks (2), but if I control the
WorkerThread lifecycle (it dies when the the Activity  pauses), then
really there is no need to use a handler, is there?  Or do I
misunderstand?

[android-developers] google analytics jar does not seem to work now

[David Liebman]

HI,

I have google analytics incorporated in my android app. When I first
added the code, and then updated my app on android market I got lots
of hits. Now I get none. I know people might just be not using my app,
but I started up the gingerbread emulator and did everything that was
necessary for my app to report using analytics. When I looked at my
google analytics page the next day there was nothing. I could swear
that this worked (from the emulator) before. Unfortunately I have no
access to an actual phone right now. Has anyone else had these
problems? Below are the links to the google analytics android jar file
instructions.

http://www.google.com/url?sa=D&q=http://android-developers.blogspot.com/2010/12/analytics-for-android-apps.html%3Futm_source%3Dfeedburner%26utm_medium%3Dfeed%26utm_campaign%3DFeed%253A%2Bblogspot%252FhsDu%2B%2528Android%2BDevelopers%2BBlog%2529&usg=AFQjCNH6acMiDzFwfl6SCUygAym80-748g

http://code.google.com/mobile/analytics/docs/android/

Here is a link to the barcode for my app on the market if anyone would
like to try it out.

Just don't add so many items, perhaps choosing which ones to add based

[android-developers] Questions about Custom (Compound) control

[Ale]

Hi,

I've developed a custom (compound) control with a count-down progress
bar that I want to embed in some my activities. Now I have the
following questions:

1 - I want, when the count down stops, to let the activity that
contains the control that the count down has stopped. How to do that?

2 - From Android documentation I read the following:

"Note that you also might introduce your own attributes and parameters
into the XML that can be pulled out and used by your constructor"

But how? Do I just need to declare in the control my own attributes,
and how to declare them in XML?

Thank you in advance!

Re: [android-developers] Questions about Custom (Compound) control

[Kostya Vasilyev]

Ale,

1 - You can model your notification on the type of interface callback 
mechanism used by Android views and widgets:


http://developer.android.com/reference/android/view/View.html#setOnClickListener(android.view.View.OnClickListener)

In your case, you'd define your own interface with a notification method 
(onCountdownReachedZero or something).


2 - Search for "declare styleable". This is the first link from Google:

http://blog.pocketjourney.com/2008/05/02/android-tutorial-42-passing-custom-variables-via-xml-resource-files/

[android-developers] Create a subset of Bitmap without make a copy

[pedr0]

Hi at all,

I have this problem, when I try to make a new bitmap for another one,
like this:

first_data = Bitmap.createBitmap(data, 0, 0, data.getWidth() /
2,data.getHeight());
second_data =  Bitmap.createBitmap(data, data.getWidth() / 2, 0,
data.getWidth() / 2, data.getHeight() );

I meet an OutOfMemoryException...

If i use only the original full image I don't meet this issues, I
think that  Bitmap.createBitmap() make a copy of the original first
image.

There are a way to specify that I DON'T WANT make a copy of that?

Thanks a lot!

Why does this happen and how can I resolve it? This thread

[android-developers] Re: MediaPlayer StreamVideo question.

[Scott Deutsch]

Mark, I will take a look at that and try out the progressbar thingy.

Now for my other issue with streaming the video (it is laggy...cause
it catches up to real time then it needs to buffer more), what would
be the best solution group?

I would like to check how much buffered then play it at a certain
percentage, but when it catches up, I would pause the video until it
buffers more then it would resume. Or, what would be a better
solution. Another solution could be downloading temp files, but I want
your guys take on that also.

My ears are open on this subject since I never tackled something like
this before.

Thanks a bunch group.

[android-developers] Simple compass functionality

[Phil Endecott]

Dear Experts,

I'm trying to understand how to get simple compass functionality
working, i.e. I have a map that I want to add a "facing this way"
arrow to.  I don't need other orientation angles i.e. it's not
Augmented Reality, but I do need it to work correctly as the display
orientation changes.  I know about magnetic deviation but will
overlook it in this post.

As far as I can see, there is a reasonably simple deprecated method: I
getDefaultSensor(TYPE_ORIENTATION), and use values[0].  It's
unfortunate that this is deprecated.

The replacement for this deprecated method seems to be:
1. getDefaultSensor(TYPE_GRAVITY) and
getDefaultSensor(TYPE_MAGNETIC_FIELD)
2. When I have new values from both sensors (which don't necessarily
arrive at the same rate), pass them to getRotationMatrix() and then
pass the rotation matrix to getOrientation() to get the angles.

...but that doesn't allow for the display orientation.  I think that I
need to get that (from where?) and subtract it from the result.

...and I also don't think it does the right thing when I am holding
the device near-vertically.  Say you're standing, facing East, holding
the device in front of your face, viewing a map; it will have East at
the top.  But if you tilt the device so it is slightly "overhanging",
this method will flip it so that West is at the top, won't it?  That's
certainly not what the user would expect.

...and I don't really think the accelerometer is needed for this.  I
think the accelerometer is only really needed to get the two other
outputs (pitch and roll) from getOrientation() that I ignore.  Though
I may be wrong about that, if I fix the previous issue, due to varying
magnetic dip angles.

So, has anyone else worked out how all of this should hang together?
Is there some simpler API somewhere that I have missed?


Thanks,  Phil.

[android-developers] Activity / Live Wallpaper communication in Android

[Josh]

I've got a live wallpaper that I'd like to communicate with from an
Activity in the same package. I've never done any work with services.
Would I be able to use the Local Service pattern, or am I restricted
because my service is a live wallpaper, and need to use Intents or
AIDL?

I think the flow would go something like this, please correct me where
my process might fail:

   1. Preview the live wallpaper from the Live Wallpaper Chooser
   2. Go into my custom Settings activity
   3. Click on a "Screen Shot" button or preference to open up a
"Screen Shot" activity
   4. Send a message to my wallpaper, asking for a screen shot bitmap
to be rendered
   5. The wallpaper service receives the message and renders its
current visuals to a bitmap in the app's data directory
   6. The wallpaper sends a message back to the activity indicating
success and location of the bitmap
   7. The activity receives this message, loads the bitmap from the
given location, and displays it to the user for further processing /
sharing

The parts I'm not sure about are the message passing in 4-7.

[android-developers] Re: IsolatedContext and AndroidTestCase.getContext()

[A. Elk]

AndroidTestCase.getContext() returns a normal Context object. It's the
Context of the test case, not the component under test.

IsolatedContext returns a "mock" Context. I put "mock" in quotes
because its not a mock in the normal sense of that term (for testing).
Instead, it's a template Context that you have to set up yourself. It
"isolates" you from the running Android system, so that your Context
or your test doesn't accidentally get outside of the test fixture. For
example, an IsolatedContext won't accidentally hit a production
database (unless you set it up to do that!) Note, however, that some
of the methods in an IsolatedContext may throw exceptions.
IsolatedContext is documented in the Developer Guide under Framework
Topics > Testing, both in Testing Fundamentals and in Content Provider
Testing.

You haven't said anything more about what you're trying to test, but I
find it interesting that you're using AndroidTestCase instead of one
of the more specific classes. Any reason for this?

Elkmeister.

The AT&T devices don't have side-loading through the UI enabled.  They still
allow development (including installing) through ADB, and as I said if they

[android-developers] Focusing a video camera

[elik]

I developed a small video camera application. It is based on code from
the android sources.
It all works fine except focus. First, I was surprised to see that the
sample video camera code don't have autofocus (or focus).
I understand I need to call camera.autofocus, but I don't really know
where is the right place to put the call it. Anyone ever succeeded in
autofocusing a video camera on android?

[android-developers] Re: IsolatedContext and AndroidTestCase.getContext()

[Mattias Svala]

I have just started out developing Android applications, so the only reason 
for me using AndroidTestCase is me being clueless about the other test case 
classes. 

The test I'm writing in this case is for testing some sqlite code. I could 
not find any test case class during my initial investigation that seemed 
appropriate for me to use. What test case class do you think I should use 
and what benefits would that class give me when testing my sqlite code?

Re: [android-developers] Re: WebView image source

[Stephen Jungels]

If the image is cached in a format that is understood by the browser
(ie JPEG, PNG), you should be able to create a content provider that
will feed the image to the browser via a custom scheme.

On the other hand this could end up wasting a lot of memory so is
there a need to cache the image, rather than letting the WebView
handle that?

[android-developers] Looking up a View inside a ViewGroup via coordinates

[Abdull]

I have a ViewGroup (for instance, a RelativeLayout). This ViewGroup is
populated with several Views (for instance, a few Buttons).
Given a Point relative to the ViewGroup's coordinate system, I would
like to look up the View which is located at this Point. That is, I'm
looking for a public method with a signature similar to

class ViewGroup {
...
public View findViewAt(int x, int y)
...
}

Does the Android GUI Framework include such a method? I had a look in
the API documentation but couldn't find something like this. Isn't
this a classic feature GUI APIs usually provide?

[android-developers] Re: WebView image source

[Neilz]

Well the reason I'm looking for a way around this is:

The WebView loads the textual content, then a second or so later the
image loads from the given URL. But when the image loads into the
WebView, it screws up the text that is already on display. For some
reason it makes it all garbled and unreadable. So I'm trying to think
of a way to have the image ready before the WebView loads.

Re: [android-developers] Looking up a View inside a ViewGroup via coordinates

[Kostya Vasilyev]

Abdull,

Take a look at the source for ViewGroup.dispatchTouchEvent.

http://www.netmite.com/android/mydroid/frameworks/base/core/java/android/view/ViewGroup.java

It has code to hit-test children, and it's only a few lines of code.

( provided you can't set click listeners on individual views, which is 
the usual way to handle this )

[android-developers] Re: does a handler prevents memory leaks???

[Kumar Bibek]

Well, if you don't handle that, it will leak. Preferably, you should
be passing the application's context and not the activity's context.
Since, Activity's context depends on the state of the particular
activity, and the context you are probably interested in inside the
Worker thread is most of the times an application context.

[android-developers] Re: What is the name of this widget?

[Kumar Bibek]

The reason why a NumberPicker is not public or a part of the SDK is
perhaps because it's not a widely used widget. If it were, it would
have been a part of the SDK, and the widget would have been public.
IMO.

There might be other reasons as well, but this seems to be the most
obvious reason. Remember, the SDK is for a mobile device.

Once we have the tablet specific SDK(if at all), we might see these
widgets as a part of the SDK, since tablets, I assume would have
better hardware than phones.

[android-developers] Re: change color of DatePickerDialog widget

[Kumar Bibek]

>From the documentation, I couldn't find an easy way to do this. The
theme, will only change things, that it declares. So, to change the
colors, you might have to dig deep into the DatePickerDialog source
code.

But, I think, an easier way to do this is to create your own
DatePickerDialog by extending the Dialog class.

[android-developers] Re: ADT plugin for Eclipse under Rational Application Developer 8.0

[Kumar Bibek]

There might be conflicts between the packages and/or classnames. The
documentation doesn't say that it's compatible with any other IDE
other than some variations of eclipse. (Even the helios is not fully
supported). So, instead of banging your head, please use the correct
IDE and it will work like a charm :)

[android-developers] Re: Google Nexus S - Please provide as DEV phone, asap :-)

[Leon Moreyn-Android Development]

Ok. So here is what I am trying to understand. I have an X10A from
AT&T. I can not develop on the phone because it doesn't allow me to
install third party none market applications. If I try to root the
phone it will remove the 3G and WIFI from functionality from the
phone. At this point I am considering the need that I may need buy a
new phone just for the soul purpose of being able to test the apps I'm
developing. Am I wrong to think that there must be something that AT&T
can provide me with to root the phone so I can develop on it?

Re: [android-developers] does a handler prevents memory leaks???

[Dianne Hackborn]

Toasts must be shown from a thread that is running a handler, and by doing
so you are causing that thread to be a UI a thread for the duration of a
toast with the corresponding constraints (it will not execute its work if
you block it with your own stuff).

You are only living on luck if you touch anything in the view hierarchy from
another thread.  The view hierarchy is very, very single threaded.  There
are some sanity checks at places for calls coming in from the wrong thread,
but they won't catch everything, and the things they don't will result in
randomly broken behavior depending on how threads race or not.

[android-developers] Re: MediaPlayer StreamVideo question.

[Scott Deutsch]

Mark, so the ProgressBar going on top of the SurfaceView worked.

Actually all I had to do was:


http://schemas.android.com/apk/res/android";
android:layout_width="fill_parent"
android:layout_height="fill_parent">






So, now I just need help to fix the lagging streaming video.

Thanks group.

[android-developers] Solution for P2P messaging on Wifi LAN

[Nathan]

I've seen some older posts on here about P2P messaging. Apparently
there is nothing built in, but there are some libraries that people
were hoping would be ported to Android.

I'm looking for a solution for messaging on a wifi local area network.
No server. No internet. No phone service.

I'd like to be able to send short messages among a group of people.

What solution would you use?

[android-developers] Re: MediaPlayer StreamVideo question.

[Doug]

Any reason why you couldn't post your videos to YouTube and let the
(often built-in) YouTube app or its mobile HTML5 web site figure out
what to do with them?  The bonus is that you do no extra coding, your
app stays smaller, and people have the option to view them in higher
quality on their desktop.

You should not as in most cases popular software is packaged. May however
be simply not in generic repository but that usually requires one action to
add or enable it in /etc/apt/sources.list
