It'll take the upload, sure, but it renders it on a black background
(at least it did mine).

[android-developers] Re: Backup of APK to SDCard.. Astro file manager does it...

[String]

Non-forward-locked APKs are just stored in /data/app, and can be
copied the same as any other file. If an app is forward-locked - what
the Market calls "copy protected" - it's kept in a different dir with
system-level privs. Which means that you need a rooted device to get
at it... but this is the major hole that forward-locking has had from
the beginning.

I was fortunate in that I'd already created 512px icons for a
different market. But yeah, definitely pretty damn annoying that this
is suddenly *required* with no advance notice.

I also dispute the whole notion of a 512px "icon". By definition, an
icon is a simple image which looks good at a small size. Even if you
have the source graphics, an icon which works well at 48px is likely
to look stupid when upsized to 512px. /grumble

Yes, it just ignores the alpha channel and that is why transparent
pixels or black.

I'll just add a white background for now.

I(We) want to know a guideline
 and it should be documented asap.

- just a high res icon? with black background? white?
- high res image with some additional
  graphic enhancement  compared to normal(low res) icon?
- image with some texts?
- like an ads banner?

and also want to know an usage of this high res icon.

[android-developers] Re: Android Project association with an emulator(s)

[adithya]

I have followed exactly the same steps you have mentioned.

Lets say i goto run->run configurations and run project1 on AVD_1, the
project runs on the specified target i.e. AVD_1
Now, i goto run->run configurations and run project2 on AVD_2, the
project runs on the specified target i.e. AVD_2

When i see the AVD's (AVD_1 and AVD_2), both are running the same
application !!

Hence, i verified the target for project1 and found that Project1's
target in run->run configuration gets changed to AVD_2 whereas it
should have remained AVD_1 which i had previously specified !

What could be the reason behind this ?? I am using android sdk 2.2 for
windows ! Is there a problem with emulator version. I had read
somewhere that m3 doesn't support multiple instances as both listen to
the same port whereas version - m5 does !! Is there a way to find the
version of the emulator ?
Do i need to download emulator m5 ? Is there a document which explains
how to configure emulator m5 with the android application we run ?

Thanks,
Adithya.

[android-developers] Re: Android Project association with an emulator(s)

[adithya]

That is exactly what i have done.

I ran project A by run->run configurations - >target - >AVD1 and the
application was running on AVD1
I ran project B by run->run configurations - >target - >AVD2 and the
application was running on AVD2

But i found that both the applications were running the same
application !

I verified this by going back to the run configurations of project A
and noticed that the target had shifted to AVD2 whereas it should have
stayed on AVD1  project B 's target was still pointing to AVD2.

What could be the reason behind this strange behavior ?

Currently ,i am using android sdk 2.2 windows.

I read somewhere that emulator version m3 doesn't support multiple
instances because all run on the same adb port !! How do i find out
the version of my emulator ?
Do i need to download version m5 to make my work ?? Is there a
document to configure the emulator to run with the new emulator as i
am using the emulator supplied by the sdk.

Thanks,
Adithya.

There's no requirement to get any approval. Do however expect
lot of negative comments and 1 star rates for doing this.

[Paolo]

Thanks Victor, for your answer, but the adapter alone doesn't solve my
problem. The softreference is cleared, by definition, when the system
needs memory, not when then objects looses all the references.

Thanks to Streets of Boston too, I haven't thounght about your
solution with LinkedHashMap, overriding "removeEldestEntry()" to limit
the cache-size. It' very interesting as solution. I'm going to try
quickly.

I will inform you about the result. Thanks to all.

Not necessarily - it all depends on how it's done. Last I checked, for
example, EverNote was using a webview to implement their "native"
Android app, and it has 12457 ratings with an average of 4.08 stars.

That's what I've done. My working assumption is that these new assets

[android-developers] Re: ConnectionPoolTimeoutException with DefaultHttpClient / ThreadSafeClientConnManager

[viktor]

You also can use next params:

 ConnPerRoute connPerRoute = new
ConnPerRouteBean(CONNECTION_PER_ROUTE);
 ConnManagerParams.setMaxConnectionsPerRoute(params, connPerRoute);

Where CONNECTION_PER_ROUTE is number of simultanious connections to
the same host

[android-developers] Re: Adding separators to a ListView

[Neilz]

Hi Kostya. It's making sense to me now, thanks for the tip.

The only thing I need to know now: I need to pass my List a Collection
of custom objects, not a Cursor. So for example I have a standard
object with getName(), I want to pass a List of these and the name
element is what appears on the list item.

Is your code suitable for this, or would I need a completely different
type of Adapter?

Re: [android-developers] Resetting a value weekly

[Vinay Julme]

You could use a remote service. I guess that would be better compared to an
activity. There maybe a better solution available using
Broadcast Receivers but haven't looked into it.

[android-developers] changes to Android Market

[Éva Lovrencsics]

Hello,

Sorry to disturbing you, but everybody got a message from Android
Market about the changes.
It says: A “feature” graphic, landscape aspect ratio, 1024 x 500 (required).
What is a feature graphic? I googled it but didn't find any example.

[android-developers] how to increase camera resolution??

[xi developer]

I run my application with camera functionality implemented in an
android-powered phone, but the camera image I got always has small
resolution. It seems by default, the android camera resolution is
small (e.g. 640*410), how to increase the resolution (e.g. to 1024 *
768), I use the following code to implement the camera part:


Intent i = new Intent("android.media.action.IMAGE_CAPTURE");

File photo=new File(Environment.getExternalStorageDirectory(),
"123.jpg");

i.putExtra(MediaStore.EXTRA_OUTPUT,
   Uri.fromFile(photo));
startActivityForResult(i, 1);

any suggestions on this???

The featured 1024 is in case your app gets featured, obviously...
you are right, I am guessing.
The whole thing must be a quiet (half of the internet is talking about
it) move to enable existing apps for Google TV.

Polishing things is a worthy cause - just look how focused and
successful Apple is with such strategy.

Re: [android-developers] view overlap

[sathvik]

May be parent container of ur custom view is not allowing your textview to
get below the imageview , increase the height of parent container and check
, check by giving marginTop (though it might not be the right soln)

[android-developers] Re: Problem with UI Thread which hangs up

[umakantpatil]

Hi,

Below is the link which shows how my UI looks:
http://i56.tinypic.com/6p89q8.jpg
You can see those articles now. Article are coming from RSS of blog.

So i m making question more simpler:

I wrote code this way as follows: (Im giving code in short)

public void onCreate(Bundle savedInstanceState) {
   super.onCreate(savedInstanceState);
   setContentView(R.layout.articleslist);
   dialog = ProgressDialog.show(Articles.this, "","Loading. Please
wait...", true);
   new InsertDataTask().execute(this);
}


private class InsertDataTask extends AsyncTask {

private Context context;
protected Cursor doInBackground(final Context... args){
//fetch all the data from db and out it in ArrayList and return 
it
}
protected void onPostExecute(final ArrayList c){
//now here is inserted for loop for rendering those
articles in UI
tablev = findViewById(R.id.articleslist);
   for(){
tr = new TableRow(context);
tr.setLayoutParams(new
LayoutParams( LayoutParams.FILL_PARENT, LayoutParams.WRAP_CONTENT));

tr.setFocusable(true);

and insert those image into tr

 When i execute the code.
Because that for loop takes 2/3 seconds to render the UI. My UI gets
hangs for those 2/3 seconds

I think you are clear now

Re: [android-developers] Re: Adding separators to a ListView

[Kostya Vasilyev]

Neil,

If your data is sitting in an in-memory collection, you can still use my 
pattern, and in fact it's even easier.


Derive your adapter from BaseAdapter, override getViewTypeCount, 
getItemViewType, and getView.


Make a small change to isNewGroup, and get the previous data item from 
the in-memory data structure (for data key comparison).


For efficiency, I recommend you use an array to hold your data objects, 
as that allows direct access to elements by index.

Is your code suitable for this, or would I need a completely different

Matt,

- how essential is phone in your scenario?
- I mean does it have to be essential in routing of messages to the
server? What I mean is that you could simply open cheapo account at
some commercial SMS gateway and it would give you a mobile number to
send messages to and from plus an API.

If you need to notify a mobile user, do it separately to the main
interaction above, as this part will be less reliable.

[android-developers] Re: Some coding errors from a novice

[student]

Hi James,
whenever  you add a new image, u should remember that, u have to add
the same image in res folder -> drawable (3 category) right same image
to add these 3 category. otherwise i wont display image and its error
should be No resources found.

U can't edit the R.java, it will be build implicitly.Once ,after u
created any modification need to change layout u should clear all
before whatever u built. (project -> clear all) then go to file and
select Build all

I hope it wil work fine.

Re: [android-developers] Re: Some coding errors from a novice

[Kostya Vasilyev]

Not true.

It's enough to have images only in "res/drawable" to satisfy resource 
dependencies.


This probably won't look good, and require alternate resources in 
"res/drawable-hdpi-v4" and "res/drawable-ldpi-v4", but that's another 
matter entirely.


2OP:

You *never* edit R.java yourself. To add images, put them into the 
folder in Eclipse. This triggers a rebuild, which automatically updates 
R.java to include the new resource ID.


You should also take a look at this:

I would not make a time-limited trial (that was kind of my point).
With the way the Android market works (and the demographics of its
users), it is not really well suited to these kind of apps.

I would look to limit the functionality/choice in your trial app
instead. I can see that you do wallpapers; you could for instance
offer a basic variant for free that does not permit any (or very
little) tweaking of your wallpaper settings. Or put in ads whenever
the settings are changed - whichever solution seems to fit best with
your strategy.

The Android market is a very different beast, for better and worse.

Visibility is an issue on the market. There's a reason that most of
the success stories on the market were either early arrivals to
Android or "big names" (e.g. Rovio).

> Or is it possible to sell good on Android market without having a
> trial version?

I think you misunderstand the purpose of a trial version in the
context of the Android market.

Keep in mind that the Android Market already implements a default time-
limited trial version of your app - ANY user can download your app and
return it within 24-48 hours practically for free. Do people really
need more than 24 hours to determine whether they want to buy your
app? I think that it is a very rare app where this would be the case.
Obviously, seeing a high return percentage on your app is not be nice,
but why spend effort implementing something which already exists in
the Android market?

I would reformulate your question into a better one (from my point of
view on what occurs in the Android Market): is it possible to sell
well on the Android Market without having an established fanbase? If
you have a killer app, maybe. For the vast majority of apps, it would
take brilliant and/or massively unscrupulous (sadly a lot of that
around too) marketing effort to generate sales.

What a "trial version" is for is to spearhead your marketing effort.
You want to put something on the market that makes people say "Man
this is awesome" -> telling all their friends about it and rating it
5* -> more downloads -> hopefully sales of your other products. What
you are most likely to get from a time-limited trial on the Android
market is a "WTF doesn't this work anymore?" and more angry users
rating your trial with 1 star. Marking your app as a time-limited
trial is not going to change that substantially. Assume that anything
you write to promote your app can and will be misunderstood (for some
users, it seems you should just assume that they can't/won't read
anything you write).

Regards,

Michael A.

Honza,


Short answer is: I don't think so.
In order to achieve this, you would need to look at Distributed
Transaction Coordinators, if you require full transactionality.

Java EE has JTA (Java Transaction API)  but it's not present on mobile
platforms. To achieve this it relies on few very crucial things:
- JDBC 2.0 drivers for each data source you need in your distributed
transaction that actually implements XADataSource and XADataConnection
- JEE Application Server

Android API mentions XADataSource and XAConnection, just have a look
at javax.sql.DataSource documentation, but there is nothing else. I am
pretty sure that SQLite does not support such mechanisms, but I could
be wrong.


You can try doing it the garage way:

   db.beginTransaction();
   try {
 //send data to SQLite
 //send data to external service
 db.setTransactionSuccessful();
   } catch (SQLException) {
  //error in DB: contact the server to revert the commit and hope
it will do it
   } catch (IOException) {
  //error with the external server, and you have no guarantee,
whether it has been written or not
   } finally {
 db.endTransaction();
   }


As you can see, you can have guarantees only about the internal SQLite
database. As soon as you involve network in your transaction, things
get orders of magnitude more complicated.
I am not sure, how strict are your requirements on transactionality.
You could also implement some timer on your server that is
transactionally persisted to a DBMS on that server, so that crash +
restart or network outage would not cause it disappear. They you would
revert any uncommitted transactions after some timeout. That gets you
somwhere, but I am pretty sure it will break in some scenarios.

[android-developers] Re: 512x512 high res icon required?

[Warren]

There wasn't much notice, but there was an email that came from
Android Market Support that gave a maintenance window and a list of
changes to the market. I was also lucky enough to have designed my
icon at 1024x1024, which I then downsize for antialiasing. As for my
other apps, I guess I'll have to redo them. Slightly annoying, sure.
But then, they are doing this to help us market our apps, so I can't
complain too much ;)

[android-developers] Re: Transactions

[biokys]

Hi Daniel,
thx for your post
my goal is to make data sharing among any users so they can store
their information locally in SQLite (in case of no network connection)
and when they want, they can synchronize these datas with central
datastore (Google app engine). so i assume, that transactional
behavior is not crucial in this case, but can be handy.

[android-developers] reading sound stream to speakers

Is there a way to  read the signal being sent to the speakers /

I would like to perform actions based on the music playing through the
speakers.  I could write my own media player so that I have direct
access to the sound stream, but that seams like overkill. It would be
much better if I could allow the user to choose any media player and
have my app use the audio output as it's input.

Is this possible? I haven't found anything about it so far.

Hey Honza,

That is true, you don't need a transaction that would span both interactions.
It would be 2 separate transactions, or to be precise 1 local
transaction and server upload would be the best effort kind of thing,
with the assumption that it will eventually work at some point in the
future (could be quite distant future in terms of transactions).

All you have to do is to have some sort of time stamp attached to the
data in both places and the server routine will ask only mobile for
the data since its latest time stamp.

You will need a BroadcastReceiver to watch for the ACTION_SHUTDOWN
system broadcast:

[android-developers] Re: cannot click on suggestion of AutoCompleteTextView

[Christophe]

It work if I use a TextView instead of my custo layout (see my first
post). Don't ask me why.
So I cheated and set the picture of the contact as the background of
the text view.
The newView method now look like this :

@Override
public View newView(Context context, Cursor cursor, ViewGroup
parent) {
float density =
context.getResources().getDisplayMetrics().density;
TextView name = new TextView(context);
name.setText(cursor.getString(1));
name.setTag(cursor.getLong(0));
name.setGravity(Gravity.CENTER_VERTICAL);
name.setTextColor(Color.BLACK);
name.setTextSize(19);
name.setHeight((int) (54 * density));

Uri contactPhotoUri =
ContentUris.withAppendedId(Contacts.CONTENT_URI, cursor.getLong(0));
InputStream image_stream =
Contacts.openContactPhotoInputStream(mContent, contactPhotoUri);

Drawable avatar;
if (image_stream != null) {
Bitmap b = BitmapFactory.decodeStream(image_stream);
avatar = new BitmapDrawable(b);
} else {
avatar =
context.getResources().getDrawable(R.drawable.contact_picture);
}

avatar.setBounds(0, 0, (int) (54 * density), (int) (54 *
density));
name.setCompoundDrawablePadding((int) (3 * density));
name.setCompoundDrawables(avatar, null, null, null);
return name;
}

Also the code in bindView is not needed (don't know why there is 2
methods newView and bindView ...)

@Override
public void bindView(View view, Context context, Cursor cursor) {
// already done in newView
}

So if you want a autocompletetextView which autocomplete on the name
of the contacts and disply their photo you can use this :

Cursor cursor =
getContentResolver().query(ContactsContract.Contacts.CONTENT_URI,
ContactListAdapter.PEOPLE_PROJECTION, null, null,
ContactsContract.Contacts.DISPLAY_NAME + " COLLATE LOCALIZED ASC");
ContactListAdapter adapter = new ContactListAdapter(this, cursor);
AutoCompleteTextView textView = (AutoCompleteTextView)
findViewById(R.id.AutoCompleteTextView);
textView.setAdapter(adapter);

[android-developers] Re: 512x512 high res icon required?

[Christophe]

well, that's great, but it would be better to know what we are suppose
to put in these pictures (icon & "feature") and where it is going to
be used BEFORE making it mandatory.

Have you looked at fcntl ?

@TreKing "without cache" means that the OS does not read the file into
the cache to improve subsequent reading operations. Sometimes you
don't want this.

If so, this behaviour is to be expected. Otherwise, this is strange.

The FRG83 image does not correspond 100% to the content of the Android
open-source tree,
but the most likely reason for the difference might be that you are running
a "user" build on the
Nexus, while you built a "user-debug" or "eng" build from the source tree.
They have a few
differences related to security which might explain the issue.

It's hard to tell without more information. For the record, can you dump the
dynamic section and dynamic symbol table from your shared library?

Thanks ernestw. You're probably right, but I'm going to have a closer
look and monitor the connections.

@victor. I've come across the connections per route params as well,
and specifying them won't make any difference in this case as that
does not effect how the connections are closed.

[android-developers] Backup in Android

[uday]

Hi All,

Im trying to do the backing up of my application's data into the
Google Servers..

For doing this i've implemented a BackupAgent in my code and i i
included this in the Android  Manifest file and "Meta-data" after
registered my Application's package with the Android Backup Service.

When i run the application to do the backup this is not performing the
backup.. Im using Nexus one device(connected to WIFI also) .

Could any one please let me know why it is not calling my
BackupAgent's onBackup() or even onCreate() methods??

Am i missing some thing, to include in the Android manifest file or
some where in the program??

I've tried the example given in the SDK samples.. But no use..

Thanks in advance for the information

Android has no access to the in-call audio stream at this time.

If the phone is in speakerphone mode, my understanding is that you can
play a media file through the speakers, and that it may get picked up
by the microphone and therefore go into the call.

[android-developers] Re: Access sensors' data directly

[babak]

Thank you for your answer,
Actually, I am using the HTC Desire and I just reach to 5Hz sampling
rate with Java-API. But it is too low for me. Do know how to reach to
50Hz, it is not important whether by using  standard API, JNI, or
working on the my phone's kernel. Actually, It is also Ok for me, if I
can reach to this performance just in my phone.

Regards.
Babak

[android-developers] Re: Access sensors' data directly

[Bret Foreman]

50Hz is nowhere near the capacity of the CPU to handle sensor data.
I've run 2000 Hz on an ARM-7 and still had cycles to spare for other
tasks. You'll need to create your own (C-code) ISR which loads values
into a circular buffer and then unload the buffer from the Java side,
passing the pointer to the buffer via JNI.

Of course, you will need to root the phone and rebuild the kernel and
it will only ever work on rooted phones with your special kernel but
it's totally doable.

Hey Bret,
Thank you for your fast answer.

[android-developers] Re: Custom Navigator app questions

[Spiral123]

wow, you're in a rush.  I thought you had all year for this project!

Google have spent man-years of development effort to build a Maps
solution.  Rather than waste the effort to re-engineer it yourself why
don't you leverage it to your advantage instead and do something
creative and interesting instead?.

Here are some suggestions:


- Build a custom overlay of the campus buildings and place them over
the Google Maps versions, so that they pan and zoom nicely as the
underlying map is manipulated.  This will also stop worries about what
will happen when you reach the end of your world.  Add a menu option
to center on the Campus and zoom appropriately so your users can
always get back to a useful starting point.

- Add a button to Turn on and off current location.

- Look at capturing touch events on your buildings so that you could
set them as destinations.

- Use intents to launch Google Navigator when they have destinations
to visit and give them walking directions from their current location.

- Go round the campus and physically check GPS accuracy in the
buildings.  If you are lucky then it may be accurate enough to allow
navigation within a building.  Do intra-building directions.

- Build a server-side app that records the trails of your users as
they journey around campus.
   - Analyse the data to find out what are the most trafficked routes
and see if you can suggest improvements to the College staff.

   - Build 'crowdsourced' feedback to show typical journey times and
color the routes according to congestion.

Build in a Manhunt or Zombie-type game where students can get points
for photographing specific landmarks or finding each other etc.


Do you really need more ideas?

[android-developers] Re: Using onCreateDrawableState

[Bret Foreman]

I'm trying to create a small "edit" icon that changes state after an
edit has been made. The icon has a white background when no edit has
been made and changes to a yellow background once the user has made
edits. This let's the user know that the underlying data, which comes
from an online source, is "dirty" and needs to be sync'ed if they want
to save their edits. So I'm really piggy-backing on the "checked"
state and taking it to mean "dirty" in my app.

[android-developers] AT&T HTC ARIA - Can not install APK

I have been looking for 3 days on how to install an APK that I created
with my SDK on my desktop.
I was able to copy the APK from my desktop to my phone but now
whenever I
try to install the APK on my phone I get an message
INSTALL BLOCKED
For security, your phone is set to block installation of applications
not source in android market.

Is it possible to install a non market APK to my ARIA?

Thanks,

Re: [android-developers] Re: Using onCreateDrawableState

[Kostya Vasilyev]

Bret,

You can use a standard ImageButton, and a state-drawable that has a 
selector for "android:state_selected".


Then use "setSelected(true)" from your code.

No custom component is necessary.

[android-developers] Re: What's a "feature graphic" supposed to contain? A list of features? Screenshots of features? (Why need screens then?)

[Patrick]

Count me in, too, as someone interested in an explanation
of this and the 512x512 "icon" (with no alpha??).

Best I can tell is the feature graphic is used when an
app gets featured by Google (not holding my breath...)

[android-developers] Update information in contacts

[vnv]

Hi,

I am trying to update information in Contacts database, phonenumber.

Analyzing following code:

public ArrayList getPhoneNumbers(String id) {
ArrayList phones = new ArrayList();

Cursor pCur = this.cr.query(

ContactsContract.CommonDataKinds.Phone.CONTENT_URI,
null,

ContactsContract.CommonDataKinds.Phone.CONTACT_ID +" = ?",
new String[]{id}, null);
while (pCur.moveToNext()) {
phones.add(new Phone(
 
pCur.getString(pCur.getColumnIndex(ContactsContract.CommonDataKinds.Phone.NUMBER))
,
pCur.getString(pCur.getColumnIndex(ContactsContract.CommonDataKinds.Phone.TYPE))
));

}
pCur.close();
return(phones);
}



I am trying to update info about record with id=1:

Doc says that I could use getContentResolver.update();

So I want to use it like

ContentResolver cr = getContentResolver();
final ContentValues values = new ContentValues();
values.put(ContactsContract.CommonDataKinds.Phone.NUMBER, "");

cr.update(ContactsContract.Contacts.CONTENT_URI, values, where,
selectionArgs);

Will this work and how to configure where and selectionArgs properly
for doing this if it works?

[android-developers] Re: Custom Navigator app questions

[Mikey]

Sorry, I didn't mean to seem pushy or anything, I'm just under a lot
of pressure from my director to be making steady progress. I will look
into overlaying the google maps this weekend. Is this part of the
MapView structure?

As for the touch events on buildings, the whole point of this app is
that incoming students don't know where the buildings are. Schedules
are given that show the name and room number of the building. Thus, I
had created a ListView with all the names of all the buildings, and
was planning to have it route you to whatever building you chose. My
idea for routing was to create a location node for each building, each
crosswalk, everywhere the sidewalk splits or turns, etc. Then, when
you hit navigate, it would center you to your nearest node, and it
would know your goal node, and then it would be a "find the shortest
path between nodes". The reason I was going to do it this way was so
that it would follow campus's sidewalks and walkways, which (correct
me if I'm wrong) Google Navigator doesn't see. Doesn't the walking
navigator only walk you along street sides?

I really appreciate the feedback! Thanks for the ideas, I'll certainly
mull them over when I hunker down with my laptop and droid this
weekend.

For zooming, determine the max and min zoom levels you want to allow and
don't allow going past that.
For panning, as the image is panned, detect when been moved as much as it
can, then force the location back to that point. So if the left edge has
been panned to the right farther than the left of the screen, force the left
edge back to the left of the screen. Same idea for the other edges.

Derive from ImageView, call super.onDraw() (or super.draw(), I forget), to
do the default image drawing, then draw your circle as required.

The draw function gets a canvas - draw on that.

[android-developers] Developing custom component for android, example - CustomSpinner

[Vitaliy Tarasenko]

Android CustomSpinner Component
I've created a custom component which works like a lock of a safe.

Component is an extention of ScrollView. It have ability to scroll
inner views, but one an inner view always will be centered. After
scrolling, the component will do own smooth scrolling to set spinner
in a correct position.
So if you use it, you can set some own views, set different
backgrounds for any view, and for header and footer of CustomSpinner.

Source you can find here:
http://code.google.com/p/customspinner/

If someone have question how to create own components or how works
mine component please answer,
but be sure that you have read this:

When using a RelativeLayout, you must specify what each child is laid out
relative to. Otherwise the layout just stacks them, as you have seen.

[android-developers] What Intent for Browser without URL

[jotobjects]

I want to invoke the internet browser app without giving it a URL to
open.  I have tried a couple of things.  What seems to work is this -

   Intent webIntent = new Intent(Intent.ACTION_MAIN);
   webIntent.addCategory(Intent.CATEGORY_LAUNCHER);
   webIntent.addCategory(Intent.CATEGORY_DEFAULT);
   webIntent.addCategory(Intent.CATEGORY_BROWSABLE);
   context.startActivity(webIntent);

Is there another or better Intent to use?  Is it good practice to use
the Launcher Intent for an app in this way?

Re: [android-developers] What Intent for Browser without URL

[Dianne Hackborn]

That is a bogus Intent; it is just blind luck that it happens to only run
into the browser as something that happens to match it, and you can't count
on that doing what you want anywhere else.

I don't believe there is a generic action to start "the browser;" you are
supposed to start it by asking it to view a URI.

Yes, we really need to know the actual size of the graphic when it's
viewed in order to figure out what to put in it. On my PC screen,
512x512 is HUGE and I could put a lot of detail in it, but if it gets
shrunk down to a centimeter or two on a side on someone's tablet
device, it's another story!

Yes, but we were told for a very long time not to use "copy

rooted users could copy off the .apk.

[android-developers] xml for email app

[John]

Hi,
  Could anybody point me to the xml that gives a layout similar to the
Android email app?
  Basically it's a list view, with 3 columns per row. The 1st and 3rd
columns are fixed width, and the middle column expands to fill the
view.

  I understand how to customize a list view, but I cannot figure out
the xml required for those rows.

Thanks,
John
