(shortened above)

Hi Ted, I have experienced the need to know the height/width of the view for 
the sizing of many components which I draw on the screen that are all 
relative to the view size.  I have found in my experience that using 
onSizeChanged is what seems to be the best approach.  It can be called 
several times (possibly even initially with 0,0 as values, unless I am 
mistaken), and each time it is called I update some variables which I then 
use to size/scale/place components.   Previously I had used onMeasure, but 
this did not seem to work as well or as cleanly.  Hopefully others can weigh 
in as I'm curious what others have done in this regard.  

This is all done outside of onDraw, though, as you do not want onDraw to do 
anything unnecessary or intensive.  The number of times onDraw is going to 
be called far exceed that of onMeasure or onSizeChanged, so keep that in 
mind - remember that it can be called many times per second, so that 
anything calculation wise or creation wise that can be cached, should be. 
 If you have elements which may involve intense calculations to scale and 
compose, then using a separate thread is desirable instead of doing it on 
the main thread.  You can perhaps take the strategy of always using values 
you have "published" and cached in your onDraw call, meanwhile calculating 
new values in a separate thread, and then publishing them when ready (with 
some synchronization/locking here - kind of a double buffering/swap effect). 
 Carefully profiling any approach will be key for performance.

Adam

[android-developers] scrollTo not working on Samsung Galaxy browser

[Novice Developer]

 We use JQuery plaugin 'scrollTo' to navigate to different parts of a
big document, or for navigating using thumbnails.
Although 'scrollTo' works fine on all desktop browsers and on iPhone
and iPad, it's not working on the android browser on Samsung Galaxy
tablet.
Anyone any clue?

[android-developers] need help with weird table

[bob]

I need help creating a weird table.  Basically, the table is a sports
stats table with player names in the first column and some stat in the
first row.  So, here's an example:


Touchdowns  Yards   Rushing 
Yards Passing
Dan Marino  2   200 
55
Chad Henne  8   700 
53
Brett Favre 7   300 
44
Emmitt Smith4   400 
108

Anyway, the thing about it is it's WAY too big to fit on the screen.
So, if it's scrolled the player name or stat name may be off the
screen.  So, the weird thing about it is that the player name and stat
name must be visible at all times.  So, I think it's kind of like a
spreadsheet.  As far as I know, there is no widget that does anything
like this.

Anyone have any ideas about how to implement this?

Thanks.

No. The specifics of this have nothing to do with Android. It will depend on

Re: [android-developers] Re: OutOfMemory exceptions

[Christopher Van Kirk]

The best strategy here is to figure out why you're running out of memory 
and re-architect your code so you don't even come close. This is a cell 
phone and tablet OS, not a surface to air missile OS. There's no need to 
be writing code that pushes the hardware to its absolute limits.

In general you can't do that. If you have an OutOfMemoryError the JVM 
can't allocate more memory and then you can't show a message or 
something because there is no memory to build the objects.

[android-developers] Too may error log output

[Hiko]

Hi,all

Below logs are taken by my Optimus Bright by LG which is based on
Optimus Black.
(the version is 2.3.3)

a usual behavior seems to be strange( it take a few seconds to move to
the next behavior).
Therefore, I took the log with logcat.

[pranay]

I have a Java server. I would like to know the mechanism for sending
images (which I will be getting from the camera) to the server? Do we
have some ready API or a simple way..?
Any help would be appreciated..
Thanks!

Re: [android-developers] Custom LayoutParams

[Romain Guy]

You need to override the method generateLayoutParams():
http://developer.android.com/reference/android/view/ViewGroup.html#generateLayoutParams(android.util.AttributeSet)
and checkLayoutParams():
http://developer.android.com/reference/android/view/ViewGroup.html#checkLayoutParams(android.view.ViewGroup.LayoutParams)
and generateDefaultLayoutParams():
http://developer.android.com/reference/android/view/ViewGroup.html#generateDefaultLayoutParams()

[android-developers] Custom LayoutParams

[Zsolt Vasvari]

I created my own Layout, let's callit MyLayout and the corresponding
LayoutParams class:  MyLayout.LayoutParams.

But when I am inflating my view from XML, it creates the child views
using ViewGroup.LayoutParams instead of MyLayout.LayoutParams.
Obviously, I am missing something in the XML definition where I tie my
MyLayout.LayoutParams to MyLayout.

Anyboyd knows what I am doing wrong here?

Probably, the EoL is encoding dependent. Try forcing the encoding to
something like UTF-8 in both ends of the socket.

In general you can't do that. If you have an OutOfMemoryError the JVM can't
allocate more memory and then you can't show a message or something because
there is no memory to build the objects.

[android-developers] Re: character replace

[bob]

This seems close to what I'm looking for, but not quite it.  I don't
want a single replacement char for all weird chars.  I want weird
hyphens replaced with normal hyphens, weird single quotes replaced
with normal single quotes , weird double quotes replaced with normal
double quotes, weird apostrophes replaced with normal apostrophes,
etc.

[android-developers] Re: BufferedReader hangs on readline

[petter]

It seem to work if I use read instead of readline like:


char[] buf = new char[8192];
int charsRead;
charsRead = d.read(buf,0,buf.length);

Are end of line characters handled differently in Android?

[android-developers] Webview UTF-8 broken?

[bob]

I made a simple test to see if the Webview correctly supports UTF-8:

wv.loadData("%E2%80%91", "text/html", "UTF-8");

If it did support UTF-8 correctly, the preceding code should load a
single long hyphen.  Instead, it loads three weird characters.  Did I
do this right or am I missing something?

[android-developers] Flash Nexus One with Gingerbread, from scratch

[JP]

I've regularly flashed my Nexus One with the various updates, GRJ22-
from-GRI40, GRI40-from-FRG83G etc.
It is my understanding these are all updates that build on previously
installed versions of Android?
If so - is there a full stock Android Gingerbread ROM for the Nexus
One that flashes a version of Android from scratch, without any prior
version of Android required? This is intended as a restore path after
flashing some custom ROMs...

[android-developers] Dynamically loading code in Android application

[Raffaele Sgarro]

Is it possible to run code downloaded ar runtime? Something like

new URLClassLoader(myURL).loadClass("MyClassName")

The class code will be in a JAR archive. The question is how do I compile 
and package that code? I think Dalvik cannot executes plain Java bytecode, 
so I'll have to postprocess the JAR with dx tool. Is is right? But 
unfortunately dx is not documented, so I really need more information on 
this topic

[android-developers] Re: Hide Phone Number in the Dialer

[Jens]

Have you tried supplying your own account manager implementation,
adding a contact with the display name "My Special Number" and then
sending your dialer Intent?

Since you cannot override (afaik) the dialer from appspace that'd
pretty much be the only way of doing it.

[android-developers] Re: Hide Phone Number in the Dialer

That should not be permitted - if an application without permission to dial 
the phone uses an intent to do so, the user needs to know what number they 
are dialing, in order to make an informed choice if they want to dial it or 
not.

Afraid this kind of thing doesn't exist.  You really don't have a way
to know what will even be used to process the ACTION_VIEW intent, and
there's no extra (that I know of at least) that you can use to make
this kind of thing happen.  Any``browser'' you will activate will have
the same properties as any other application, and there isn't any way
to specify this in other apps either.  (I would suppose that you would
model this as passing a continuation to the called app as code for
onBack? ...,)

tl;dr:  no, no flag.

[android-developers] BufferedReader hangs on readline

[petter]

I'm trying to read a response from a server and
BufferedReader.readline will block and never return.

If I run the exact same code from the command line on my Linux host it
works, but it will hang when run on my emulator or device.

Here's the code

try {
System.out.println("will call socket!");
mysocket = new Socket(hostname, portno);
System.out.println("Connected to " +
mysocket.getInetAddress() + " on port "
   + mysocket.getPort() + " from port " +
mysocket.getLocalPort() + " of "
   + mysocket.getLocalAddress());

DataOutputStream os = new
DataOutputStream(mysocket.getOutputStream());
DataInputStream is = new
DataInputStream(mysocket.getInputStream());

BufferedReader d = new BufferedReader(new
InputStreamReader(is));

if (mysocket != null && os != null && is != null) {
os.writeBytes(command + "\r\n");
String line;
System.out.println("calling readline after command:" + command);
line = d.readLine();
System.out.println("got: " + line);
return line;
}
}
catch (UnknownHostException e) {
...

What I see on android is:

I/System.out(  644): will call socket!
I/System.out(  644): Connected to /192.168.1.109 on port 4998 from
port 52695 of /10.0.2.15
I/global  (  644): Default buffer size used in BufferedReader
constructor. It would be better to be explicit if an 8k-char buffer is
required.
I/System.out(  644): calling readline after command:getversion
D/dalvikvm(   98): GC freed 2313 objects / 133904 bytes in 67ms
W/KeyCharacterMap(  644): No keyboard for id 0
W/KeyCharacterMap(  644): Using default keymap: /system/usr/keychars/
qwerty.kcm.

On Linux (OpenJDK) I get what I expect:

Connected to /192.168.1.109 on port 4998 from port 33097 of /
192.168.1.104
calling readline after command:getversion
got: 710-1001-04
getversion returned: 710-1001-04

Any ideas? Is the BufferedReader different on Android?

[android-developers] my_activity -> brower-activity (How can I go back to my activity)??

[Satya Komatineni]

My Activity A  starts BrowserActivity with a URL. (No flags)

I press BACK button while in the browser

Browser follows its own history back and not come back to my activity A.

Because I am starting the browser activity (I do realize it is a
singletask) is there any flag I can set to have the browser honor the
activity that is invoking it?

Appreciate your help

If this occurs consistently, even after restarting the emulator, there
is something with your network that is interfering (e.g., firewall,
proxy server). You will need to contact the people in charge of your
network for assistance.

I can proportion for you to load instance runntime and find input

See

[android-developers] Re: Got the Bluetooth blues: Service Discovery Failed

[gjs]

Hi,

Sort of, there is a common UUID used most for 'serial devices', this
is mentioned in the docs -

'Hint: If you are connecting to a Bluetooth serial board then try
using the well-known SPP UUID 1101--1000-8000-00805F9B34FB.
However if you are connecting to an Android peer then please generate
your own unique UUID.'

See 
http://developer.android.com/reference/android/bluetooth/BluetoothDevice.html#createRfcommSocketToServiceRecord(java.util.UUID)

Give it a try with your device. I find it works it most bluetooth GPS
devices, laser range finder and other BT serial devices on Android. I
only use a random UUID if I am connection to another Android device
using BT.

Regards

In two days my market statistics show 5 orders but my orders page
shows only one.
Are orders registered later?

[android-developers] Re: OutOfMemory exceptions

[gjs]

Hi,

These are typically OutOfMemory errors (not exceptions) which you can
catch in a try catch block, you can then hide these errors from the
user or display a friendly message. Most commonly on this list, they
are usually associated with trying to allocate memory for bitmaps that
are too large. If so try using smaller of less images & remember to
recycle bitmaps when done.

Regards

Re: [android-developers] Re: character replace

[Miguel Morales]

Right, this should be fairly automatic.  Read the file in as a utf-8
stream and output as ascii.
Post some code, and what you're trying to do.
