[android-developers] Re: etting SIGNAL 11 error

[ko5tik]

SIGNAL 11 means that something went wrong in native code,  and proces
was killed
because of segmentation violation - this comes from outside of davlik
- that's why you do not have stack
trace.
The question is:  what did you try to do  before this crash?

[android-developers] List onItemSelectedListener not working

[Varun Tewari]

Hey Guys,

While working with fragments i am trying to have one list in left panel and
detail fragment in right side of it.
I have my first item item already selected as soon as i launch app. And
"SHOULD HOLD ITS SELECTED STATE"
I tried using onItemSelectedListener with setSelection(0), but it didn't get
called. Any one knows the reason?

Reg,
Varun

[android-developers] Re: Honeycomb / 3.0 / OpenGL ES / Broken / Again!?!

[MichaelEGR]

http://mobile-broadband.t-mobile.com/android-tablet/g-slate

I believe it was previously called the LG Optimus Pad before release?

It could be an issue from LG perhaps with a pseudo-incomplete GL
driver and not in the court of the Android team / Google. One would
think the default Honeycomb implementation I assume from Google was
heavily tested against the Tegra 2 SoC and may exhibit the problem say
on the Xoom or other Honeycomb tablet. I have yet to test anything
beside the G-Slate.

My assumption is that without being able to test directly (IE print
out all the config profiles the GL driver returns to verify) is that
the likely optimum depth size could be 32 for the Tegra 2 devices and
that the max my config chooser currently searches for is 24 (2nd gen
devices) and this is not present on Tegra 2 devices (3rd gen).
Therefore depth 24 does not match anything and the further default
fall back searches for depth size 16 which is located as a "valid" GL
config found by TyphonRT.

So 5/6/5/16 works OK with the G2x, but fails with the G-Slate. No
EGL / GL errors are raised and 5/6/5/16 comes back as a valid config
arrangement on the G-Slate, but it's broken such that no rendering
occurs with this non-optimum config setting.

The expected behavior I believe is that some sort of rendering should
occur if a valid GL config is matched and a context obtained even if
it is not the optimum config. Of note though there are no perceived
performance problems with the G2x at this config setting.

It seems obvious that 5/6/5/16 is not the optimum configuration for a
Tegra 2 device (was the optimum setting for gen 1 devices). Once I
modify the default fall back settings and include 5/6/5/32 as the top
config to search after verifying that indeed is a valid target in
general I'm guessing things will match up with the optimum supported
config on Tegra 2 devices and things will be fine. It just happens
that things are not borked on the G2x at 5/6/5/16, but the G-Slate
fails with this setting further misleading me.

As things go I've yet to add external settings (extra XML file /
external config by exception, etc.) to configure GL config parameters,
so until I finish rebuilding my platform in ~1-2 weeks I won't get to
update the defaults or finish the external XML config mechanism. In
the future with my efforts an external XML file that can filter by
device / family as necessary can provide the GL config decision tree
and not rely on the hard coded default decision tree, so testing will
be easy in the future without recompiling.

Regards,
--Mike

[fr4gus]

If you are using Eclipse, when you "Export" the project, you can
create your own certificated during the process. Keep in mind, that
once create the certificate, you have to keep it in a very secure
place because subsequent updates of your application must be signed
with the same certificate.

Re: [android-developers] Re: How do you counter repeated bogus reviews from competitors?

[Brill Pappin]

TreKing,

You might try osTicket for your support system instead of the blog... it 
doesn't have the problems your describing using the blog and its fairly 
light to run (runs fine on an AWS micro instance).

We've been using it fine for several months and even added our own hack that 
allows us to pass a non-english support request through Google Translate 
with the touch of a button (very handy).

We are currently looking at using zendesk, but its a bit pricy if you have 
more than one support agent. The advantage is that they have an Android lib 
that allows users to contact support directly from your app, which we think 
is a win/win.

Its Zendesk or we will create a UI for osTicket

[android-developers] Re: How do you counter repeated bogus reviews from competitors?

[Brill Pappin]

Actually Pent, touching my own review and actually addressing a negative 
reviewer by changing the text is the *only* way of combating these people.
I do it routinely and even for legitimate users who need help (in which case 
I point them at support). This has the advantage that the first review a new 
customer has is a 5 star rating.

The other advantage to the "touch"  feature is that quite often a user will 
get to support and I'll help them out or fix a bug, the user then comes back 
and adds more stars and edits their comment to something more positive.

Anyway, i really hope they don't suddenly remove that "touch" feature 
because its actually one way to get the nefarious competitor reviews buried 
and/or addressed.

I'm not surprised your short today...
My orders stopped processing at 9:25 PM yesterday (Apr 24th).

I've got a bunch of new orders that have not been processed (which is 
unusual).
My guess is that there are a team of engineers and PR people working over 
night as we speak :)

Likely some of them are kicking themselves.

If you wait around for the Android Market monkeys to do anything, you're
going to die waiting. Even if they implemented a way to respond to users, it
would be half-assed and mostly non-functional, if the statistics and error
reporting "features" are any indication of what these clowns are capable of.

I've taken matters into my own hands - I respond to comments on a blog that
my app is rigged to check for new posts. When I get a stupid comment /
rating, I post a response. When a new response is posted, users get an alert
(if they leave the option enabled). With enough luck, the user it's actually
targeted at reads the response. I've addressed many complaints this way and
makes for a fun interaction with some users. In addition, other users see
that I response and hopefully learn to ask about issues. But of course, when
I respond to all issues, I then get complaints about the alerts of me
responding to issues - even when they can be disabled. You can't win against
stupid.

In your case, I would have alerted a fairly large number of my users to
this douche competitor and very surely would have not only had a large
number of positive reviews burying their comments, but probably would have
had enough people marking it as spam to have it removed. And if I knew the
offending competitor, I could name them and let the users bombard them with
negative reviews (of their own accord, of course ;-) )

[android-developers] Re: what's the unit of "setStrokeWidth()" (dp or pixel)

[Zsolt Vasvari]

AFAIK, every measurement in Android is in pixels.  When you define
something in dp or whatever else in dimens.xml or in your layout, they
get converted to pixels.  The easit way to do it is to define your
measurements in dimens.xml and that way you can use whatever UOM you
want and the system will take care of the conversion for you.

It's been the top requested feature of the Android Market since
probably day 1.

Obviously, if it hasn't happened already, it won't -- at least not
until there is a "regime change" in the Market team.

Hi Michael,

I changed MiFareClassic object to IsoDep. But I am getting the

Must I add in additional code to sustain the connection? (Am I

[android-developers] Re: How do you counter repeated bogus reviews from competitors?

[MB]

Hi Brill,

Thanks a lot for the response and the suggestions. I updated the app
description with a one liner indicating what our specific competitor
has been upto.

Given how sensitive an app's quality perception is based on top
reviews, I really wish Android market provided their vendors/
developers a way to respond to comments esp. to  users who frequently
update/touch their comments.

Thanks,

--MB.

Calling native functions for rendering from

[android-developers] what's the unit of "setStrokeWidth()" (dp or pixel)

[xeagle]

Hi,

I need draw a "dotted line" in my app. I use codes below:
Paint paint = new Paint();
paint.setColor(0xff00b900);
paint.setStyle(Paint.Style.STROKE);
paint.setStrokeWidth(1);
paint.setPathEffect(new DashPathEffect(new float[] {5, 5, 5,
5}, 1));
canvas.drawLine(0, 50, 160, 50, paint);

Now I'd like know the unit of parameter of "setStrokeWidth". Is it dp
or pixel? If the unit is "dp", will the line seems same width in
devices with different DPI?
I test it on emulator and my phone, it seems that "x,y" coordinate of
"drawLine" is "dp".

Thanks

[android-developers] Code an Education Revolution (@Qykno) in 54 hours! Location: San Francisco Bay Area

[Kalimah Priforce]

 

Code an Education Revolution (@Qykno) in 54 hours!

 

Location: San Francisco Bay Area (San Francisco, Oakland, Berkeley)

 

Event: Startup Weekend Education (June 3rd - 5th) 

 

On June 3rd - 5th, an event called Startup Weekend Education will gather 
hackers, hustlers, and designers together and for 54 hours, teams will be 
formed around groundbreaking ideas, and each team will be engineering their 
product on-premise for the length of the entire weekend.  There will be 
guests speakers, press, and a panel of judges who will be judging each 
product and its pitch at the end of this build-a-thon.

 

The Mission: Careerspotting 4 Kids

 

Should you choose to accept it, is to build a minimum viable product of 
Qykno, a Careerspotting for Kids platform that exposes youth ages 12-21 to 
career possibilities using video storytelling and social gaming.  There are 
two pathways to take for a MVP depending on the skillset of the team:

 

(1) Web app of Video Storytelling - A catalog of video content that features 
the stories of professionals sharing the how-tos of their journey.

 

or

 

(2) Mobile app of "roadmapping" that will be a location-based social game 
where kids receive awards and points for checking into destinations related 
to their career path.

 

Team Qykno:

 

Will consist of five core members - three uniquely talented coders and:

 

Kalimah Priforce (me): 12+ years in education, youth dev. & biz strategy | 
Co-Founder @ Qykno

Taisha Rucker: Attorney | Program Director at Pacific Educational Group

 

Taisha and I will handle content creation, be responsible for marketing the 
product, and recruiting the UI/UX design and video production talent to the 
team from those in attendance.   I'll pitch the concept to the crowd and 
draw excitement for the project.

 

Must haves:

   - Able to work with a diverse team with other programmers/developers in 
   an intensive fast-pace environment.
   - You care more about getting it done than it having to be perfect.
   - Experience with at least one modern programming language such as Ruby 
   on Rails, PHP, AJAX, ActionScript, Python, C++, C#, Objective C, or Java.
   - A love of games and gameplay.

 

Nice-to-haves:

   - Social game development experience.
   - Experience with Facebook APIs.
   - You're available to join our team full-time; must have a flexible 
   schedule.

 

The Perks:

   - We pay for your entry ticket ($75) value, plus food and transportation 
   to and from your residence.
   - If we win, $5,000 divided amongst the team, plus the recognition of 
   winning a high profile tech event.
   - Guaranteed invitation to join the co-founder/management team and join 
   us for startup seed accelerator programs in the summer.

 

Contact us: team[at]qykno[dot]com, 347-985-0365, skype/gchat: kapriforce

 

We'll be making our final decisions by mid-may.

[android-developers] Re: Honeycomb / 3.0 / OpenGL ES / Broken / Again!?!

[MichaelEGR]

Romain thanks for asking all the right questions.

It appears that the GL config matching system I have needs a little
modification though it should still not fail as I'll describe below.

Of interest all 2nd gen devices (Droid, N1, Nexus S, etc.)
appropriately find the "high quality" parameters as specified in the
default fall back scheme (a config by exception system):
EGL_RED_SIZE: 5
EGL_GREEN_SIZE: 6
EGL_BLUE_SIZE: 5
EGL_ALPHA_SIZE: 0
EGL_DEPTH_SIZE: 24
EGL_STENCIL_SIZE: 8

On the G2x / Froyo for whatever reason the "high quality" default
settings are not matched and the "mid quality" default config is
chosen, but everything runs perfectly fine and fast:
EGL_RED_SIZE: 5
EGL_GREEN_SIZE: 6
EGL_BLUE_SIZE: 5
EGL_ALPHA_SIZE: 0
EGL_DEPTH_SIZE: 16
EGL_STENCIL_SIZE: 8

With the G-Slate the same "mid quality" config is chosen and a context
and everything succeeds in being created with no EGL/GL errors except
no rendering / blank screen. Even the 1st thing done in the demo is to
set ortho mode and simply draw a texture to the screen (not rocket
science here), so nothing complex is done regarding cameras or other
typical GL problems and there are no hard coded parameters (screen
size, etc.) that should break any fundamental rendering. There are
also no other errors raised while the normal execution path /
rendering loop engages.

So for the G-Slate even though those config values result in a valid
context currently it seems the GL drivers or something of that nature
are not liking it despite this very same config working fine on the
G2x / Tegra 2.

As mentioned I've been doing a very large refactoring of the TyphonRT
codebase making it a fully component oriented architecture and have
been working on it since July 22nd (last day when I compiled all the
demos). Granted I had a 5 month full time contract in between then and
now working part time (Sept-Feb). I'm just about to finish the full
component rearchitecture / refactor and get 3D support back up and
running here in 1-2 weeks when I can address any changes to the GL
config / chooser support.  So the demo apps I've been using were last
compiled back in July which is no problem really. I thought I had a
robust enough of a default fall back system, but apparently not.

I still think it may be a bug / issue with the G-Slate in regard to
being able to setup a context with likely non-optimal settings causing
a blank screen / no rendering. Something should still render
regardless.

A similar issue occurred with Android 2.0 and the Droid when the "mid
quality"  settings (essentially depth size of 16 instead of 24) caused
a hang in the GL driver. 2.0.1 fixed that and when depth size 16 was
chosen things worked, but less efficiently..

In my current case with the G-Slate those settings don't raise any
errors or signs of failure except for no rendering which was the same
symptoms surrounding the Android 2.0 failures and that got my mind
running.

Once I get the platform fully reworked here I'll examine things deeper
and figure out the right default GL config fall back mechanism to
support the G-Slate. I've been fairly stressed as of late with the
remaining work I've been doing as it's complex and I'm overshooting
desired time estimates. The last thing I need are fundamental driver
issues. I admit I had 6 devices working with only the G-Slate failing
and I tossed it in a proverbial tub of water and it floated and thus
this "it's a witch" post occurred. ;P

I still think there is a general error regarding GL support with the G-
Slate especially since the G2x / Tegra 2 works fine with the same
parameters, but this is a solvable problem and not the end of the
world.  I think each dev working with low level stuff should get at
least one pass for an "it's a witch" post.. ;P

Regards,
--Mike

[android-developers] Re: Problem setting file permissions when filename has a space

[Paul]

Thanks - my implementation looks correct, so no idea why it's not
being called.  Tried tracing the call to
getContentResolver().openFileDescriptor() and it seemed to be invoking
openAssetFileDescriptor(), so intercepted openAssetFile() in my
content provider, but it too isn't being called.

Re: [android-developers] Re: Problem setting file permissions when filename has a space

I don't know if it will help, but here is the source to the media provider
which implements openFile:

http://android.git.kernel.org/?p=platform/packages/providers/MediaProvider.git;a=blob;f=src/com/android/providers/media/MediaProvider.java;h=7a72e239b0291e6b2ef986c4f675d58dfcda0732;hb=HEAD

This allows for example sharing of pictures in Gallery to work.

Well if I can get the openFile override working, I won't need to use
the cache directory and won't need this at all, so this shouldn't be
an issue moving forward.

The content provider is published in my manifest:



I am using it for all DB activity in my app, so it's working... and
have tried the following, and no errors are generated:

getContentResolver().openFileDescriptor(Uri.fromFile(shareFile), "r");

But... this does not trigger a call to openFile().

As I've switched over to passing the SEND the path directly to my file
in the app's file directory, versus the path to the one I was copying
to my cache directoy, the Uri for this is now:

/data/data/package.name/files/1.png

I get a permissions error now (as expected), but again, no call to
openFile().

[android-developers] Re: Custom preference, targetSdkVersion=“11”: missing indent?

[Zsolt Vasvari]

FWIW, I have a bunch of custom Dialog preferences, but I don't see the
issue you are seeing.  They look just like the standard Honeycomb
ones.

That said, I've had a custom layout pre-Honeycomb, to support multi-
line preference titles (why is it restricted to a single line???), so
that looked like your "bad" preference on Honeycomb -- I know only set
the cusom layout if I am running on a pre-Honeycomb system.

RE: [android-developers] Help in simple read/write applications.

[Tommy]

I didn't think you could access app files between apps... Why not create a
folder on the SD card and write the file there that way both apps have
access? Maybe I am wrong about apps being able to access eachothers files
other than with maybe custom providers? Maybe you could try using an Intent
from App B to call an activity on App A that passes back the data you are
looking for?

[Zsolt Vasvari]

This is exactly the kind of stuff why people scream about
fragmentation.  It's OK that devices are different, but they should be
determinably different.

I think this is where Google needs to step in and revoke the license
of the non-open source stuff until device firmwares are fixed and
updated to comply with the test suite and not report bogus values.

Just a static constant is fine.  For example:

This may not be a safe assumption.  For example the send will often take a
while, so an implementation may very likely exit once the send has been
confirmed and execute the operation in a background service.

Have you published the content provider in your manifest and ensured you
have set the authority correctly there in and the Intent's URI?  Have you
tried opening it yourself to see if it works?  Is anything interested

[android-developers] Re: Possible to use OpenGL in both C++ and Java?

[Indicator Veritatis]

The "normal way" is to use the NDK. There is a separate Google group
for that. But if you really need to port a large body of C++ code,
that is the way to go. Otherwise you could have to rewrite using the
Android Java OpenGL interface, which is basically JSR-239 with some
"glue code" for connecting to Android's SurfaceView, the parent class
of GLSurfaceView.

See http://developer.android.com/sdk/ndk/overview.html for more about
the NDK.

Re: [android-developers] Re: System.exit

[Dianne Hackborn]

System.exit() will not necessarily fix this.  If the application has left
its activity stack in a bad state and does this in the background, the stack
is still being maintained by the system and will be restored as per its last
state when the application's process is re-created.

Also system.exit() can break the behavior of an app, so it should be
avoided.

I am storing it in the XML as a way of storing the value... any other

I'm not counting on it returning anything useful, just having the
functionality indicate that it has finished is enough, I am then
setting a boolean field to true when it does, so that I know I that
the app has created a temporary copy of the file in the app's cache
directory.  On exiting the program, if the field is true, I then empty
the cache directory.  Obviously don't need to do this if I am no
longer copying the file if/when I get the method you suggest using
onFile() to work.

On that front, I have overriden the onFile() method in my content
provider, but it is not being triggered by the above code, any
suggestions?

@Override
public ParcelFileDescriptor openFile(Uri uri, String mode) {
  Log.d(LOG_TAG, "openFile() called");
  return null;
}

[android-developers] Re: System.exit

[Indicator Veritatis]

System.exit() as a feature for the paranoid user? I wish that were
never necessary. But there is yet another case where I wish I had the
app calling system.exit() itself: when the app has done a bad job of
keeping track of state, and leaves the user, yes, even the
sophisticated user, with no idea how to navigate back to a known good
state in the menu tree. Then the only way for me to get the app back
to the top of the tree is to kill it with SystemExit (the application,
not the API) and start it again.

One of the promised benefits of certain competing Android Application
Markets is that the Market staff will verify the program the developer
submits, checking for stupid errors like this one, as well as other
failures to do Android Lifecycle management correctly before approving
the application for distribution. But I haven't had enough experience
with them yet to know whether they keep this promise or not. They may
have found they bit off more than they could chew.

Dianne-

What you say is true, at least for those of us who accept the party
line Google has been preaching for years, but you have not answered
the question. In fact, one could believe you had answered it only if
you confused the contrary and the contradictory of a non-null
affirmative categorical statement.

In fact, the mismatch between his question and your 'answer' is giving
me good ideas for how to update SylloGizmo to support using the
Square of Opposition in entering and analyzing categorical
syllogisms;)

Re: [android-developers] Fragments for Google Maps add on?

[Streets Of Boston]

You're right. That's still the same (btw, the docs say you can have multiple 
MapActivities per app, as long as they are in different processes "... *Only 
one MapActivity is supported per process* ...").
 
The post above describes how you can have a MapView in a Fragment using the 
V4 compatibility library's sources.
I was interested in this, because I'd like to use the LoaderManager getting 
data from the web to display on a map.

OK, I thought you literally didn't know what you variable "parent" was,
which didn't make much sense :-P

Well, I've not used PopupWindow myself, so I don't know what to tell you.
FWIW, I tried an equally simple example (threw a textview with "Hello" in it
into a POW and tried to show it at the location of a ImageView I have in a
listview) and it did not work either.

Also tried showAsDropDown() and that didn't work either. I've seen the thing
used in plenty of other apps so I'm sure it works, but I guess it's not
as straightforward to use as it would appear.

But I don't provide the layout for the preference. It's a

Re: [android-developers] Custom preference, targetSdkVersion=“11”: missing indent?

If you are using the Holo theme, the preference item now needs to take care
of the indent itself.  This is to allow items to have things like icons
within that area.  I believe there is a resource/attribute for the indent
size, though I don't recall it off-hand.

[android-developers] ViewFlipper and ScrollView animation

[Rick]

I have a scroll view that wraps a view flipper with 2 form-input
views.

I can use animations for some fancy transitions between the two but
the primary view is significantly larger than the second view.
As a result, when I am at the bottom of the primary view and I hit a
button that should transition me to the secondary view, the primary
view is forced back to the top then starts the transition.

What I really want is for the transition to start with out having to
scroll to index 0. It should transition with out moving the scroll
position.

Any ideas?

I've tried a couple of different things for parent.  Here is the full
method -

public void onClick(View v)
{
PopupWindow popup = new PopupWindow(context);
TextView contentView = new TextView(context);
popup.setContentView(contentView);
contentView.setLayoutParams(
new LayoutParams(LayoutParams.WRAP_CONTENT,
LayoutParams.WRAP_CONTENT));
contentView.setText(text);
//View window = ((Activity)context).getWindow().getDecorView();
popup.showAtLocation(v, Gravity.CENTER, 0, 0);
}

It does compile and tracing it with the debugger it executes without
error.

Re: [android-developers] Fragments for Google Maps add on?

[Streets Of Boston]

The option from Valentin in stackoverflow doesn't work well with the 
*compatibility 
library*. This is what i did to make it MapActivity work with Fragments 
using the compatibility library (it is not the best solution, but it seems 
to work so far):
 

   1. Use the source of the compatibililty library (just copy android/* into 
   your project's source dir). 
   2. Rename (don't refactor!) FragmentActivity.java into 
   AFragmentActivity.java (rename file and class-name). 
   3. Create a new java file FragmentActivity.java. Make it an interface 
   (see below). 
   4. Have AFragmentActivity implement FragmentActivity. 
   *public class AFragmentActivity extends Activity implements 
   FragmentActivity ... *
1. Fix the compiler errors that will happen.
  2. instead of .mFragments, use getFragments()
  3. instead of mHandler, use getHandler()
  4. add casts that will cast FragmentActivity into Context or Activity 
  where necessary.
  5. etc.
  5. After all compiler errors have been fixed, make a copy of 
   AFragmentActivity.java and call it AFragmentMapActivity.java and have it 
   extend MapActivity
   *public abstract class AFragmentMapActivity extends MapActivity 
   implements FragmentActivity ...*
   
Now you can have a MapView in a regular fragment as long as that fragment is 
hosted inside a AFragmentMapActivity.
 
Source of the FragmentActivity interface (without the imports and such):
*package android.support.v4.app;*
*...*
*...*
*public interface FragmentActivity {
 public ClassLoader getClassLoader();
 public View findViewById(int mViewId);
 public Context getApplicationContext();
 public Resources getResources();
 public Window getWindow();  
 public LayoutInflater getLayoutInflater();
 public boolean isFinishing();
 public void onCreateContextMenu(ContextMenu menu, View v, ContextMenuInfo 
menuInfo);*
** 
* public FragmentManagerImpl getFragments();
 public Handler getHandler();*
** 
* public LoaderManagerImpl getLoaderManager(int mIndex, boolean 
mLoadersStarted, boolean b);
 public CharSequence getText(int mBreadCrumbTitleRes);
 public void invalidateFragmentIndex(int mIndex);
 public void onAttachFragment(Fragment f);
 public void startActivityFromFragment(Fragment fragment, Intent intent, int 
i);
 public void supportInvalidateOptionsMenu();
}*

[android-developers] Custom preference, targetSdkVersion=“11”: missing indent?

I am not having a lot of luck on this one over on StackOverflow:

Summary: I have a custom preference that works on Honeycomb, but the

it's not indented, and the fonts appear a bit larger. This *feels*

Share/send is not an app.  It is a convention for applications to interact

No that is the standard way it works.

There is no reason for this string to come from a resource; it is not
something that gets localized, it is just a constant.

ACTION_SEND is not specified to return anything, so if you are getting any
result at all you can't count on what you get back being useful.

[android-developers] Re: Push notifications

[nikhil]

I am not sure if there is an app for twitter or facebook.

I had used push notification in one of my apps and I had used a third
party api. You can visit xtify.com for more details.

Google has also introduced push notifications I believe, the only
thing is user needs to login to gmail I think but I am not sure..

[android-developers] Re: Problem setting file permissions when filename has a space

[Paul]

So just to clarify (as I have no access to the other app and what it
calls, in this case the other app is the OS-standard 'share/send'
functionality), I override the openFile() method in my app's content
provider, and then when I trigger the 'share' functionality and pass
it in the Uri to the file, the share functionality will then make a
call to openFileDescriptor() which will call my overridden
openFile()... correct?

Anything special I need to do to trigger this workflow, other than the
standard:

Intent share = new Intent(Intent.ACTION_SEND);
share.setType(getString(R.string.note_default_mime_png));
share.putExtra(Intent.EXTRA_STREAM, Uri.fromFile(shareFileCopy));
startActivityForResult(Intent.createChooser(share, "Share"),
ACTIVITY_SHARE);

Thanks,

Paul

I don't think your question is very clear. However, off the bat I would say
you do not need a "MyForm" class that extends View. You just need a layout
defined in XML that lays out your form and you can set that as the content
for your view. As for "refreshing", most things are automatic (like setting
the text on a TextView) but if you need to force refresh you can look at
invalidate().

[android-developers] Re: Market sales suddenly cut in half

[Brill Pappin]

I just did some data analysis on our orders from our local database copy.
(we're in canada, so the only way we can calculate tax is by scraping the 
checkout pages).

it looks like our overall orders have actually dropped (which suggests a 
change in the market, not Checkout) but that the ratio of cancels to charged 
has also gone up (suggests a change in Checkout, not Market) after the 19th, 
until april 24th when we get a whopping 50% cancels!

It's pretty clear that there is some sort of problem...

in the interest of helping to get this resolved, here are our numbers, 
charged vs. cancelled, for the last several days, so other publishers can 
compare with their own data:

total financial_status day
26 CANCELLED 2011-04-24
26 CHARGED 2011-04-24
10 CANCELLED 2011-04-23
28 CHARGED 2011-04-23
15 CANCELLED 2011-04-22
39 CHARGED 2011-04-22
11 CANCELLED 2011-04-21
31 CHARGED 2011-04-21
14 CANCELLED 2011-04-20
34 CHARGED 2011-04-20  <== orders get mucked up here
20 CANCELLED 2011-04-19  <== Last normal day of sales
57 CHARGED 2011-04-19
24 CANCELLED 2011-04-18
45 CHARGED 2011-04-18
22 CANCELLED 2011-04-17
42 CHARGED 2011-04-17

I don't know if anyone else is seeing numbers like this, but for us this is 
a big deal as our margins are not that great.
I've already asked support if something has changed in the Market recently, 
but i haven't taken this to Checkout yet.

Maybe if one of you Google employees who have an eye on this stuff can pass 
the problem along, it would be helpful.

Re: [android-developers] Re: Fragmentation-resistant product design

Yes, I think I'd agree :)

and your right, what we're really interested in is the actual values.

We noticed that the Motorola Atrix reports the wrong stuff, but not only 
that, my partner did some manual calculations on screen size/density and 
discovered that not only is it reporting the wrong stuff, but its actually 
got the wrong values for the basic dimensions that those values are based 
on.

Anyway, when we get this stuff up, i'll post to the list and see if anyone

[android-developers] # downloads seems to get stuck in marketplace admin console?

[Mark Wyszomierski]

Hi,

When you log into the admin console for android marketplace, we see
two numbers:

N total
N active installs (M%)

These numbers appear to get "stuck" for me quite regularly. The new
hyperlink named "stats" shows me active installs per day which seems
to really be updated daily. I am also tracking installs as a side
effect of the nature of my multiplayer game, so I'm again sure
downloads are going up.

I'm just wondering which numbers to trust here, or why the values seem
to get stuck. Are they only updated once weekly or something like
that?

Thank you

In this case, I think a popup window makes sense. An incoming call already

There are no formal requirements. The emulator is slower for newer
versions of Android and for larger screen sizes. Also, the emulator
uses only one core of your CPU, so having multiple cores may not help
you much.

So, for example, a dual-core 2.5GHz CPU with 4GB of RAM can run the
Android 1.5-2.2 emulators just fine, 2.3.3 emulator OK, and 3.0
emulator poorly. A quad-core 2.66GHz CPU with 4GB of RAM has much the
same experience.
