[android-developers] Re: Anybody experiencing a boost in sales since opening up to other countries?

[JonFHancock]

Just curious.  Are you all using anything other than the Google
Checkout interface to track sales?

I'm using a paid app called Android Market Report.  It hasn't been
particularly great, but it does show the net sales for each day/week/
month.

[android-developers] Re: Creating a .jar Library

[Doug]

Android project aren't meant to export jars from source code.  The
documentation makes this clear.  They export raw source which gets
compiled directly by dependent projects.  If you want to add a jar
file, I think you'll have to do arrange for Eclipse to pick up a
static jar from a different project with manual configuration.

[android-developers] Re: WebView class from android supports xhtml, html4, html5 ?

[097]

As I know, WebView (1.6 or above) supports XHTML and html4.
If you merely want to display text mixed with images, you can write a
html4 page.
Hope it will help you.

Please explain to me how exactly you know what "normal" is given that
the stat has a long reputation for being inaccurate over the past few
months.  :-)

[android-developers] Drawing on canvas random pngs as game pieces

[acr]

Hello,
I am in the beginning stages of developing my first 2d puzzle game
(7x7 grid kind of like bejeweled), and looking for the best method to
implement the following:

draw 49 random pieces(from 7 original pngs) on the board that can be
moved around without redrawing the whole board. I can get this drawn
out nicely with a basic for loop using
BitmapFactory.decodeResource(getResources(),... but Im not sure where
to go from here plus when I change the screen orientation the pieces
regenerate randomly. Any help pointing me in the right direction would
be greatly appreciated.

Thanks

hi cindy,

Do you know how can I save a streaming video from the position the
MediaPlayer is currently playing?
Because since the streaming is already playing, I assume all the
connection is fine. Can I use some shortcut commands to save the
current playing streaming video? Thanks.

[android-developers] Re: Unit testing a class that uses android.os.Handler

[DanH]

Re starting a thread, on most JVMs it's a relatively expensive
process, and it would be better to keep a thread "warm", with a
Handler waiting, than to start new ones for every operation.

But of course that depends on how frequently you need the thread.
(Would be kinda nice if Android had an implicit async thread you could
throw stuff to, and Android started and ended the thread based on
usage and memory pressure, just like all the other components they
manage.)

Re your test case, it doesn't work because you misunderstand how the
event loop works.  Sending a Message to a Handler just queues the
message, and it doesn't get handled until the thread returns from
whatever work it's doing to the event loop.

Presumably something in the event loop triggers a call to
testHandlerShouldReceiveMessagesPostedToIt.  While that method is
running the event loop doesn't.  While you're waiting in sleep,
nothing's happening -- sleep does not run the event loop.  The event
loop will not run (and process your message) until you return from
testHandlerShouldReceiveMessagesPostedToIt.

What this means is that any sort of sequential programming where you
"wait" for something must be broken into separate segments and
threaded together via Messages and Intents and whatnot -- waiting in
any form is verboten (at least in the UI thread, or any thread that
uses an event loop).  Takes a whole new mindset to design an activity
that must, eg, handle a communication protocol or handshake with an
asynchronous activity.

[android-developers] Creating a .jar Library

[JoeSchmoe]

Do I have to do anything special to create a .jar library with
Android?  I'm simply creating an Android Project and then doing
"Export Jar".

I'm able to do "Add External Jar" and I can compile fine.  When I run,
the classes are unresolved so I crash. (null exception...)

I tried exporting as a "Runnable Jar", but the "Finish" button is
greyed out.  Perhaps I need to create a different project to use a
runnable jar?

Thanks in advance!

[android-developers] Re: Unit testing a class that uses android.os.Handler

[Jeremy Wadsack]

Actually, having thought about this more, I recall my original intent
was to only spawn the thread for the time needed to do the task. That
means I don't have to worry about shutting down or closing the thread
when the application closes. (The task responds to the application
through one or more listeners that are Runnables, but it checks if
they are null before calling them.)

This approach assumes that the gc in Dalvik won't mind spinning up
objects and threads and destroying them regularly. I don't know if
that's better practice for the jvm, but this seems less likely to
produce leaks, right?

I changed the code to use a handler on the main thread. The handler,
when it receives a message, starts a new thread with the long-running
task. Unfortunately the handleMessage method is never called when the
object is built from my test code.

So let's take the threading out of it for a moment. Why does this
basic test case fail?


import android.os.Handler;
import android.os.Message;

public class TaskManagerExample {

  // Test field for inspection
  public boolean messageHandled = false;

  private Handler handler = new Handler() {
@Override
public void handleMessage(Message msg) {
messageHandled = true;
}
  };

  public void start() {
  handler.sendEmptyMessage(0);
  }

}


import android.app.Application;
import android.test.ApplicationTestCase;

public class TaskManagerExampleTest extends
ApplicationTestCase {

public TaskManagerExampleTest() {
super(Application.class);
}

public void testHandlerShouldReceiveMessagesPostedToIt() {
TaskManagerExample example = new TaskManagerExample();
example.start();
try {
Thread.sleep(500);
} catch (InterruptedException e) {
}
assertTrue(example.messageHandled);
}

}


I put the sleep in there, just in case messages sent to the queue take
some time to get processed. Seems half a second should be plenty of
time (and keeps the test responsive). I tried it with five seconds and
it still fails.

What base *TestCase class should I be using the get Handlers, Loopers
and the MessageQueue to run under test?

"Correct" is debatable - there are always multiple ways to solve any given
problem and as I said I haven't actually used Gallery so I couldn't confirm
for sure if this is even doable, but I don't see why it wouldn't be.

If you prefer to wait for the work to be done for you and hope to find it on
the interwebs, or have someone point you to an answer, or give it outright
to you, that's clearly up to you.

However, you should consider that in the time you've posted this and waited
for a response, you could have thrown together an simple example to verify
whether this works or not. Putting together a layout with an image and text
and seeing if it shows up correctly in a Gallery should take all of 10
minutes (assuming you already have *something* to work off of).

[android-developers] Re: TableLayout and displaying Database data

[Brion Emde]

I suggest you start by looking at the Notepad sample, included in the
SDK in the samples directory. That shows how to do a query and display
the result in a list view. The code can also be found in the
developer's page: 
http://developer.android.com/resources/samples/NotePad/index.html

Since you would need to build your table layout contents dynamically,
it would be best if you got the basics down first.

Forgive me if you've already done this and I'm just telling you
something you already know.

Among other things, it does Z-axis ordering, which LinearLayout and

Re: [android-developers] Slow initial showing/drawing of Activities when using own Theme

[Dianne Hackborn]

First, a theme MUST inherit from one of the standard ones.  If it doesn't,
some things won't work now, some things will break in the future, etc.

When an app is being launched for the first time, a preview of it is first
shown by constructing a window with the theme from its manifest and showing
that.  The delay from when that empty window is shown until the actual app
is faded in is the time it is taking your app to launch.  If you want to
reduce that, you need to profile and optimize your app's launch time.

[android-developers] Re: Creating a vertical spacer

[DanH]

Yeah, I need to study up on RelativeLayout a bit.  Haven't quite
figured out what it can do that others can't (other than to make
things much more confusing).

[android-developers] Gone element blocking the view

[Yahel]

Hi all,

I have a fairly easy layout : Two relative layouts filling the parent
frame layout.

firstRelativeLayout appears first in the xml and secondRelativeLayout
appears next.

firstRelativeLayout  has it's visibility not set in the xml (visible
by default).
secondRelativeLayout has it's visibility set to gone.

firstRelativeLayout respond to touch perfectly.

Then I programmatically set secondRelativeLayout visibility to visible
and back to gone.

firstRelativeLayout does not respond to touch anymore.

Any idea what can go wrong ?

Re: [android-developers] Android - landscape-right and landscape-left orientation

[Dianne Hackborn]

Sorry, there currently isn't any way to do this.  Even if you were to
monitor the orientation yourself, there isn't a constant to set the screen
to the alternative landscape orientation.  (Also trying to use the
orientation listener for this would be very tricky since to do this
correctly you need to know how to deal with screens that are landscape when
not rotated etc.)

A future version of the platform should have APIs to help with this.

[android-developers] Re: Possible to check .apk signature?

[DanH]

Yeah, I did some poking around in a small apk and that's what I'd
found.  Just hadn't gotten around to coming back and reporting on it.
(Kinda want to do a little more research, just to satisfy my own
curiosity.)

Make sure you don't try this from your PC.  The URL only works from

[android-developers] Slow initial showing/drawing of Activities when using own Theme

[Streets Of Boston]

When i create an activity that uses a custom-theme, e.g.
android:theme="@style/MyLogonTheme".

I create my theme in styles.xml:


sans
@drawable/
android_screen_logon_bg


(note that i have a few more themes and plenty more styles in
styles.xml, but they are not in use for this particular activity).


When the activity is started brand new (e.g. after the process has
just started), it starts VERY slowly:
1. The background (windowBackground) appears quickly, in a timely
manner and the activity's 'setContentView' is called almost
immediately in the onCreate.
2. However, the activity's content-view (setContentView) finally shows
up 0.5 - 2 seconds later (depending on the speed of the phone)!

When i remove the 'parent' from MyLogonTheme's definition:

sans
@drawable/
android_screen_logon_bg

Both the background and the content-view appear quickly!

Somehow, including the inheritance from the "android:Theme" slows
things down quite considerably.

Why is this the case?
Is there a way around it?


I looked at the log... no special output that may indicate
something... it is just slow.


BTW:
If i do remove the parent="android:Theme" part, things do load/show
quickly, but i get quite a few warnings in the log. The warnings
complain about layout_height is missing and some ColorStateList with
TypedValue (0x2/0x1010059 a=-1) can not be found. They are just
warnings... i see no other side effects.
If i specify the parent="android:Theme", I don't get these warnings.

Can I just remove the parent="android:Theme" part and live with the
warnings?


Thanks!

Re: [android-developers] Trouble with Shared Prefs.

[Kostya Vasilyev]

Don't call edit() multiple times.

Every call to edit() creates a new "change session", so you're changing the
value but not committing the change, and then starting a new changeset and
committing it with no new values.

Hey there all,

I'm having a problem that i don't know how to resolve.

I have a broadcast receiver catching a call from the system.  I need
this receiver to set a flag so that the next time my app runs it can

I am trying to do this with a shared pref but it is not working.

In the receiver I do:

 SharedPreferences sharedPreferences =
context.getSharedPreferences(PREFS_NAME, Context.MODE_PRIVATE);
 sharedPreferences.edit().putBoolean("changed", true);
 sharedPreferences.edit().commit();

Then when i start my app I check like so:

sharedPreferences = getSharedPreferences(PREFS_NAME,

if (sharedPreferences.getBoolean("changed", false)){
   hasChanged = true;
   sharedPreferences.edit().putBoolean("changed", false);
   sharedPreferences.edit().commit();
}


This does not work.  If I download the file from the emulator after
the receiver has triggered it is empty.  It exists but there is no key
value pair.

What am I doing wrong?  Is there a better way to flag my app to run
differently on next startup?

Any help???

Re: [android-developers] bugreport tutorial

[Dianne Hackborn]

Um.

Ahahah.  Hah.  Ouch.

It's probably better to specify fairly specifically what information you
want to get out of one...   there is obvious a *lot* of information, for a
wide variety of things, ranging from hard core kernel developers to
individual app developers.  Nobody understands everything in there.  It's
just everything that we can reasonably generate that might be useful to
diagnose some problem that has happened.

[android-developers] Re: Anybody experiencing a boost in sales since opening up to other countries?

[Zsolt Vasvari]

Sorry, I take that back.  There was one attempted sale in those 6
hours that failed with "The authorization of the customer's credit
card failed."

I see a lot of those in bunches, also.

[android-developers] Re: Anybody experiencing a boost in sales since opening up to other countries?

[Zsolt Vasvari]

Yes, it is very strange.  No sales again for 6 hours, and these 6
hours is when my app sells the most, as it's the afternoon/evening in
the US.  I can't prove that something is wrong, but it certainly is
mind-boggling.

Re: [android-developers] Re: Possible to check .apk signature?

[Dianne Hackborn]

An .apk is a super-set of a .jar, and uses the standard Java certificate and
signing mechanisms in a .jar.  If you are concerned about this being
broken...  well, not sure what to say. :}

Remember that you are putting it in a RelativeLayout. Unless you
specify some other widget as being relative to the View, it's just
going to sit there.

Re: [android-developers] Re: Creating a vertical spacer

[Tom Gibara]

It's not really possible for the system to know this at build time. The
presence of the layout_ attributes can be provided by styles that may be
absent in some resource configurations. Because of this their omission is
essentially a runtime condition.

Well, it doesn't die when I add layout_height.  Doesn't do what I want
(of course), but doesn't die.

Would be nice if this could be reported at build time.

[android-developers] TableLayout and displaying Database data

[Boardy]

Hi all,

I am currently looking in to developing an application for the android
platform. I have some information that is stored within the SQLite
Database of Android.

What I want to be able to do is to perform a query to the database
table and populate a TableLayout with the information from the
database table.

I have tried to find this on the Internet but have not had much luck.
If anyone can help me to get about doing this would be great.

Cheers.

I haven't started yet since I wanted to make sure I wasn't heading

I prefer to stand on the shoulders of giants.

I'd use android:layout_marginTop="200dip" on whatever is below your

Can you post the exception associated with the "horrible death"?

Re: [android-developers] Creating a vertical spacer

Difficult to say without the stack trace, but I notice that there's no
layout_height attribute on the View.

I was referring to the fact that the Android app model makes most of
that stuff useless, since virtually all communications between threads
is via Intents, Messages, et al, vs actually sharing memory.

[android-developers] Creating a vertical spacer

[DanH]

Kind of an newbie question, I suppose -- I haven't done much playing
with layouts yet --

I want a spacer in a layout to space some text down below the "live"
part of a background image.  I tried this:


http://schemas.android.com/apk/res/
android"
android:id="@+id/CheckDeviceConnectivityView"
android:layout_width="fill_parent"
android:layout_height="fill_parent"
android:orientation="vertical"
android:background="@drawable/i_notice_background"
android:paddingLeft="15dip" android:paddingRight="15dip">


. . .

Which seems straight-forward enough.  But setContentView dies a
horrible death when passed the layout.  (And it works fine without
that View element.)

What am I doing wrong?  What's the best way to create a spacer?

Allowing multiple threads direct access to UI state causes a lot of
pain (every data structure needs to be synchronized, lots of
opportunities for races and funky timing issues).  You really want the
UI to be single-threaded.

"Greatly discourages sharing" seems like a bit of an over-statement.
The Java programming language provides well-defined methods of sharing
data between threads, and the Java memory model rigorously defines
what is and isn't expected to work.  (Or were you referring to
something else?)

[android-developers] Re: GLSurface doesn't draw anything when i came back again.

[Lance Nanek]

Well, one thing I can think of, make sure you are reloading your
textures in Renderer#onSurfaceChanged. They get cleared more often
than onSurfaceCreated is called. Also make sure your Activity is
calling GLSurfaceView#onPause and onResume at the right times.

Check www.netmobo.com. There's an API that supports collecting
payments regardless of app store and regardless of country as long as
you have the ability to receive supported payment methods in your
country. Supported payment methods are credit cards, Paypal and Google
Checkout. Cash cards in your country may also be supported.

No. It gets better, but it's not fixed by any means. I pumped out an update

[android-developers] Re: Checkbox with multiple lines with different font size

[DanH]

You can supposedly do some formatting of text in TextView (and
subclasses) by creating a Spanned object out of
android.text.HTML.fromHtml() and then doing setText with that Spanned
object.  The documentation's a little (OK, a lot) vague as to what
subset of HTML is supported, though.

I have not used Gallery, but considering it's just another ViewGroup, I

your image + text. Have you actually tried anything yet?

What you're looking at is a preference. You can achieve the same effect by
using a CheckBoxPreference yourself. If a preference is not what you want,
you can create a simple layout that has two text views and a check box setup
the way you want.

[android-developers] Re: Goo Market Frustration(s) -- a request to experienced app developers

[Nathan]

The failure may very well be non specific to a Hero.
In addition, there are some things that may break on Hero that won't
break on others.

If you run it in a 1.5 emulator, you will already find out if you are
using APIs that weren't available in 1.5.
Also try to run it hundreds of times consecutively in the emulator to
see if you can trigger OutOfMemory.

The HERO handles memory poorly and has less RAM allowed per app than
other devices.
1.5 does not allow certain flags on BitmapFactory that would help the
memory situation a lot.

The combination of these two things is what I believe is causing a
crash that a user reported ( still without many details).

Except for the fact that I've already had 1.5 enabled for some time, I
would consider not supporting 1.5 in the manifest.

[android-developers] Re: Possible to check .apk signature?

[JonFHancock]

I think we're finally  understanding each other, Dan.  I am using the
public key as a secure way of identifying that the app is mine before
I pass data back from the server.  The CRC323 isn't really used.  I do
pass it as an extra piece of information that loosely identifies a
specific build.

The key identifies the app as validly signed by me.  The CRC32 just
loosely says that this build is different from that build.  I do not
depend on it for anything important.

The automotive test tool business is fairly big.  Mostly they use

some sort of dongle to read computer info, do ignition analysis, etc.

Trucking companies may be in the market for specialized apps for
tracking their routes, etc.

Otherwise, how about an app that just shoots the driver if he attempts

Re: [android-developers] Follow up for the active install count problem

[Stephen Jungels]

My count had dropped to the point where it looked like an abandoned
app (about 33% at the lowest, I think).  It started to stabilize and
then go up again, and after I did a release a few days ago it jumped
from 37% to 45%, so I think releasing an update will get things back
to normal more quickly than waiting it out.

[android-developers] Re: Possible to check .apk signature?

[DanH]

Getting back to the original topic, there is a scheme that would be
fairly secure if the regular JDK were used but is probably broken by
Dalvik:  Have the server specify a random class in the application,
and random start/end offsets in the class's bytecodes, and have he
application then do ClassLoader.getResourceAsStream to open the class
file, access the bytes, and compute a checksum on them.  The
combinations would be innumerable, so there's no way the values could
be precomputed, and by using getResourceAsStream you're sure that the
actual code bytes are being referenced.

Alas, it's not perfect, though:  The hacker could install a separate
copy of the original code as a raw file and write his own replacement
for getResourceAsStream.  Would be a fair challenge, though.

And, of course, the whole scheme is torpedoed by Dalvik, since the
bytecodes are not preserved and getResourceAsStream on a class file
likely errors out.

[android-developers] 3D Model Loading Problem

[souza]

Hi everyone,

I'm developing an android application for my thesis and I need to load
a 3D model into it. I have decided to use the .obj file structure as
input. After some searching in the internet and also here in the
Android Developers group I found an object loader provided by the
project android-gl (http://code.google.com/p/android-gl/). Its
ObjectLoader.java file provides the following load methods:

public Model load(InputStream in)
throws IOException

public Model load(String file)
throws IOException

My problem at the moment is to correctly load the model into my
application so that I can see it on the display. I have integrated the
loader call inside the onDrawFrame method:

public void onDrawFrame(GL10 gl) {

gl.glClear(GL10.GL_COLOR_BUFFER_BIT);
gl.glFrontFace(GL10.GL_CW);
gl.glEnable(GL10.GL_CULL_FACE);
gl.glCullFace(GL10.GL_BACK);

for(int loop = 0; loop < 2; loop++) {

if(loop==0) {
gl.glViewport(0, 0, w, h);
gl.glMatrixMode(GL10.GL_PROJECTION);
gl.glLoadIdentity();
gl.glOrthof(-1.0f, 1.0f, -1.0f * h / w, 1.0f * 
h / w, -2.0f,
10.0f);
}

if(loop==1) {
gl.glViewport(0, 65, w/2, w/2);
gl.glMatrixMode(GL10.GL_PROJECTION);
gl.glLoadIdentity();
GLU.gluPerspective(gl, 45.0f, (float) w / 
(float) h, -2.0f,
10.0f);
}

gl.glMatrixMode(GL10.GL_MODELVIEW);
gl.glLoadIdentity();

gl.glClear(GL10.GL_DEPTH_BUFFER_BIT);

if(loop==0) {
gl.glPushMatrix();

gl.glEnableClientState(GL10.GL_VERTEX_ARRAY);

gl.glEnableClientState(GL10.GL_TEXTURE_COORD_ARRAY);
gl.glBindTexture(GL10.GL_TEXTURE_2D, 
textureId);

gl.glTranslatef(0.0f, 0.0f, 10.0f);

gl.glVertexPointer(2, GL10.GL_FLOAT, 0, 
vertices);
gl.glEnable(GL10.GL_TEXTURE_2D);
gl.glTexCoordPointer(2, GL10.GL_FLOAT, 
0, texCoords);
gl.glDrawElements(GL10.GL_TRIANGLES, 
mIndices.length,
GL10.GL_UNSIGNED_SHORT, indices);
gl.glPopMatrix();
gl.glDisable(GL10.GL_TEXTURE_2D);
}


// NOW THE PART WITH THE LOADER


if(loop==1) {
gl.glPushMatrix();
gl.glTranslatef(0.0f, 0.0f, 5.0f);
// loading 3D model
try {
-> loader.load(new 
FileInputStream("sdcard/
pixbag.obj"));
} catch (FileNotFoundException e) {
   e.printStackTrace();
} catch (Exception e) {
   e.printStackTrace();
}
gl.glPopMatrix();
}
}

gl.glDisable(GL10.GL_CULL_FACE);
gl.glFlush();
}

Since I'm working with the android emulator I wanted to load the obj
file out of the emulated sdcard device. But when I'm trying to push a
file onto it using DDMS in eclipse the console returns the following
lines:

Failed to push the item(s).
(null)

I also tried to push the file using the command line tool without
result :( So for now without the model I'm even not sure if the loader
does what it's supposed to do.

Another way I tried was to have the obj file in the assets folder of
my eclipse project from where I also load my texture file. So I have
modified the above-mentioned lines concerning the loader to:

InputStream in = getAssets().open("pixbag.obj");
loader.load(in);

This revision neither worked. I still cannot see the 3d model. Any
help and advise on how I can load and display the 3d data in the
emulator is more than appreciated!

thanks in advance,
Sadi

Right, they usually don't.

Curiously enough, if a task killer or custom firmware is involved, users 
tend to blame the most recently installed application, or one that 
misbehaves (while being killed repeatedly, never having a chance to do 
what it's supposed to).


I'm glad to see this tightened in Froyo.

No. The one star person is unlikely to come back or help you anyway.

my apps which would beg them to get in touch with me if they have
*any* problem at all ...  is this my only means to accomplish this?

Yes, that is probably your best option. Loading up the app with
admonitions is what works best. Get them subscribed to your
newsletter, give them handy error report buttons, walk them through
every step they have to take avoid errors.

Even then, you won't completely prevent comments like you've seen.
Many don't spend more than seven seconds on an app, and not everyone
wants to help improve or fix an app. The app can be working fine, but
not work the way *they* expect, and you will still get that comment.

[android-developers] Horizontal scrolling list with image and text

[Lance Hill]

It seems like the best way to create a horizontal scrolling list of
images is to use the Gallery widget. I need to display sidebar text
with each image.The examples I have seen showing how to use the
Gallery widget only show images. Is it possible to display a list of
images+text descriptions in a Gallery, and if it is, does anyone have
an example of how to do this?

[android-developers] Follow up for the active install count problem

[Fabrizio Giudici]

 Just received this from the Market support:


We wanted to follow-up. By now, you should have noticed that the installs 
metrics for your applications have been restored. We identified the problem as 
occurring with application updates only, have made some changes recently that 
should resolve and prevent this problem. Please let us know if this error 
persists.

If we can assist you further, please let us know.



In my case, things have not changed at all. Downloads are increasing 
(1550) and active installs stabilized at 29% (the value before the drop 
was 44/45%). So, indeed active installs are increasing again - 29% is 
stable since three weeks - but the original percentage was not restored. 
Now, I don't know what to think... Maybe the problem is not solved, 
maybe in my specific case the active installs really dropped for a while 
(but it's curious that it only happened for a while...).
BTW, I didn't release any new upgrade since then (I have a new one 
almost ready, but I'm beyond schedule because of personal problems) - 
and maybe the count would fix itself with new upgrades...


What would you do now? Is there anybody else for which the problem was 
not solved?

[android-developers] Re: Goo Market Frustration(s) -- a request to experienced app developers

[Bret Foreman]

When my app encounters an error it pops up a message with two buttons
- "Dismiss" and "Email Error Report". The error report builds an XML
document with every detail I can query about the phone and emails it
to a dedicated address. This tends to give me at least basic data even
from someone who just downloaded, tried it once, discovered it didn't
work on their phone, and uninstalled it. Half the time, they also
click the "Email Error Report" button so I have both their email
address (in case I have questions or want to let them know I fixed
their problem) and the report data.

In the next release of my app, I plan to record a "menu history" which
will be included in the error report, enabling me to replay the user's
actions. All of this is fairly easy to implement, especially compared
to the normal cat-and-mouse game of trying to get enough data from a
user to diagnose his/her issue.

Users also get a chance to add comments to the email before it's sent,
or to opt out at the last minute. So far this approach is working
great and total implementation time was about a day.

[android-developers] Re: How to convert xml to svg in Android

[DanH]

If at all possible you should use a utility to convert the SVG to some
other format before loading it onto the phone.

[android-developers] Re: Unit testing a class that uses android.os.Handler

[Lance Nanek]

Handler has multiple constructors. The ones that take a Looper
argument can take the Looper for a Thread other than the current one.
That way you don't need to create the Handler on that Thread and it is
easier to ensure it is not null on the Thread using it. There's also
an android.os.HandlerThread utility class that is pretty much just a
Thread with a Looper. It has a getLooper method that's easy to feed
into the Handler constructor and that avoids the issue with prepare()
taking a while sometimes and leaving you with a null longer than you'd
expect.
