[android-developers] google api demo question about drawBitmapMesh algorithm

[a a]

Hi all,

I'm not good at mathematics algorithm, so i can't undanstand the following
code

private void warp(float cx, float cy) {
final float K = 1;  // why it is 1 ??
float[] src = mOrig;
float[] dst = mVerts;
for (int i = 0; i < COUNT*2; i += 2) {
float x = src[i+0];
float y = src[i+1];
float dx = cx - x;
float dy = cy - y;
float dd = dx*dx + dy*dy;
float d = FloatMath.sqrt(dd);
float pull = K / (dd + 0.01f);

pull /= (d + 0.01f); // so it is pull = d * K /
(dd),what is it meaning ?

// let me take a example, there have a triangle, a, b, c

// pull is c/sqrt(a*a + b*b)  then * 1? what is the
result meaning?? maybe the c/sqrt(a*a + b*) is 1 or less 1 or more then 1.
can anyone tell me why  it * 1?
// and what it meaning about the result  d * K / (dd), ?


android.util.Log.d("skia", "index " + i + " dist=" + d + "
pull=" + pull);
if (pull >= 1) {
dst[i+0] = cx;
dst[i+1] = cy;
} else {
dst[i+0] = x + dx * pull;
dst[i+1] = y + dy * pull;
}
}
}

best regards, thanks.

[android-developers] Android with Python

[raduq]

What do you guys think about Android applications developed with
Python? I'm going to start a mobiel applications training in a company
and i have received a few hours ago an email that told me to read
about Python before the first class.

I am very surprised because I thought Android apps were made only by
using Java and/or C#. Do any of you have developed Android apps with
Python?

If yes, please tell me how it is compared to Java, if you have any
experience with Java.. Is it easier, are the Python apps faster than
Java ones? I'm asking this because I would like to know the advantages
and disadvantages of developing apps in Python before I begin the
training.

Thanks in advance for your answers!

[android-developers] search hardware button

[John Goche]

Hello,

I was wondering whether I can rely on an android phone having
the search hardware button because I am thinking about hardcoding
some specific function to it in my application, but then if it is not
avaiable
on some smartphone models this would be a problem.

Any feedback welcome,

John Goche

[android-developers] SurfaceView no longer adjusts canvas to screen size?

[Michael A.]

I've run into a weird glitch.

Since the early versions of the SDK, I've been using a SurfaceView to
draw graphics, painting a bitmap into the canvas and then drawing/
painting on top of it, while adjusting the drawing dependent on the
density of the phone.

Since SDK14, however, this behavior seems to have changed.

Even though I run it on a 480x800 HDPI view, the SurfaceView returns
320x460 in the code for the dimensions of the view and the same for
the canvas in the code. This of course messes up everything, as I
still scale my drawing. If I remove the scaling, it works correctly
again, as the SurfaceView seems to be automatically scaled up
according to the density settings, but it looks terrible now (since
the graphics are scaled up 1.5 - before the SurfaceView used the hdpi
graphics, now it seems to use the mdpi graphics which are then scaled
up).

Is this intentional? Did I miss a memo somewhere?

Re: [android-developers] SurfaceView no longer adjusts canvas to screen size?

[Kostya Vasilyev]

Sounds like compatibility mode scaling. If your manifest is properly set up
with minSdk set to 4 or above, I would think it's an emulator bug.

Re: [android-developers] search hardware button

[Michael Banzon]

My initial response was going to be something like: I can run Android
on everything - so don't rely on my fridge having a "Back"-button.

After considering it some more: If you are going to publish your app
on Android Market you should check the requirements for Android
Market. AFAIK it requires the handset maker to obtain a license from
Google which might put some restrictions/requirements on hardware.

Re: [android-developers] search hardware button

[Latimerius]

I asked this question about a month ago - you might want to check this:

http://groups.google.com/group/android-developers/browse_thread/thread/cf312b4dd2fdb440/dd7c156d618e0bdb?lnk=gst&q=how+to+check+if+device+has+hardware+search+key#dd7c156d618e0bdb

TL;DR: you can't rely on pretty much anything being there and in
general, you can't even check.

It is workable but it still sucks because you have to rely on the user
being agile enough to set their own controls to get most of your app.

[android-developers] Custom preference (slider) on a non-touchscreen device - how to convert left/right keys to slider change?

[lbendlin]

A number of my custom preferences are of the'"Seekbar" variety. They can be 
adjusted nicely on a touch screen device. However, our app is no also being 
used on the Parrot Asteroid which doesn't even have proper left/right keys 
(the scroll wheel emulated up/down).  
I can map the media keys prev/next  to left/right, so there is a hardware 
workaround. I just don't know how to catch these key events for my custom 
preference (without impacting the up/down paradigm) and convert them into 
slider changes. I guess worst case I could override the onClick event for 
the custom preference so that hitting the big button would cycle through a 
few discrete slider settings. 
 
Is it possible to override onKeyDown for a custom preference?

Re: [android-developers] Custom preference (slider) on a non-touchscreen device - how to convert left/right keys to slider change?

[Kostya Vasilyev]

I don't see anything in Preference that would do this out-of-the-box.

However, you could receive key events in your PreferenceActivity 
subclass and dispatch it to the current (that would need to be defined, 
too) preference.


Another way that comes to mind is using a dialog preference with a 
slider, instead of a slider directly in the preference list... which has 
the advantage of already having the concept of currently affected value. 
You'd then receive key events in the dialog (sub)class.


( Regarding the device - are there still cars that can use those 
DIN-sized radios? I thought this was a thing of the past, apparently not? )

Re: [android-developers] SurfaceView no longer adjusts canvas to screen size?

[Michael A.]

Seems like you were right. i was forced to reconstruct all of my projects 
due to the library problems with the new ADK/ADT, and apparently the 
manifest settings switching off the compatibility mode had somehow gotten 
lost in the transition.

Many thanks for the timely help. It's been so long since I last had to 
dabble with those settings that I had completely forgotten that they 
existed.

Regards,

Michael A.

[android-developers] Re: How to obtain A-GPS data via Android phone

[Kenneth WON]

Hi, lbendlin,

I just want to obtain a more accurate location (such as latitude and
longitude. etc) no matter it is in indoor or outdoor.
And how to implement it?

Thanks and Regards,
Kenneth Won

[android-developers] Re: Should I use the same certifcate for all my apps or a different one per app?

[Michael A.]

I've only seen one good argument for having multiple keys, and that is if 
you - at some point - would want to sell off one of your apps to someone 
else. Because of the way the market works, the only really practicable way 
to do that (without recoding the thing and submitting it as a whole new app 
- not likely what a purchaser would be interested in) - is to transfer the 
key certificate to the buyer. Which is not ideal, of course, if you have a 
bunch of other apps using the same key.

It's worth remembering if one is building apps for others, but I can't see 
it being much of an issue for the majority of app developers.

Re: [android-developers] How to get updated c2dm registration Id.

[Studio LFP]

What type of response code are you getting from the C2DM server when you 
try to send a message to that specific device ID? It will let you know if 
there is any issues with your current device ID.

[android-developers] GROUP_SOURCE_ID -> GROUP_ROW_ID caching issue

[Jay]

I'm not sure if this is a bug in Android, a bug in the emulator, or a
bug in my code. I have a syncadpter that creates a few groups and
populates them with raw contacts. The code works as expected on a
freshly booted emulator. If I delete the syncadapter's account the
groups and contacts are deleted as expected. However, if I then add
the account back, the groups and contacts are recreated just fine, but
are not linked together properly. Based on looking at the contacts db
with the adb shell, it seems that the GroupMembership data rows (which
were added with the GROUP_SOURCE_ID parameter) are using the
group_row_ids from when the groups were created the first time. So it
looks like there is a stale GROUP_SOURCE_ID -> GROUP_ROW_ID cache
being used somewhere. Does this look like a platform bug, or is there
an api for clearing such a cache I should be using?

Thanks,
Jay

This is the inner loop of my contact create code. The necessary groups
have already been created.

// Contact does not exist; create him
final int backRef = batch.size();
batch.add(ContentProviderOperation.newInsert(RawContacts.CONTENT_URI)
.withYieldAllowed(true)
.withValue(RawContacts.ACCOUNT_TYPE, account.type)
.withValue(RawContacts.ACCOUNT_NAME, account.name)
.withValue(RawContacts.SOURCE_ID, serverId).build());
// Attach names
batch.add(ContentProviderOperation.newInsert(Data.CONTENT_URI)
.withValueBackReference(Data.RAW_CONTACT_ID, backRef)
.withValue(Data.MIMETYPE, 
StructuredName.CONTENT_ITEM_TYPE)
.withValue(StructuredName.GIVEN_NAME, 
contact.getGiven())
.withValue(StructuredName.FAMILY_NAME,
contact.getFamily()).build());
// Attach groups
for (final long groupServerId : contact.getGroups()) {
batch.add(ContentProviderOperation.newInsert(Data.CONTENT_URI)
.withValueBackReference(Data.RAW_CONTACT_ID, 
backRef)
.withValue(Data.MIMETYPE, 
GroupMembership.CONTENT_ITEM_TYPE)
.withValue(GroupMembership.GROUP_SOURCE_ID,
groupServerId).build());
}

Re: [android-developers] How to get updated c2dm registration Id.

[Studio LFP]

That should be a correct response. You may want to refresh your C2DM key on 
the device and then refresh the server with the updated one. You may want 
to call the unregister intent on device first with the following:

http://code.google.com/android/c2dm/index.html#unregistering

I would figure that unregistering a device would remove all previous 
entries if there is more than one entry. I'm not sure that there can be 
more than one ID for a device for the same app, but it is worth trying the 
unregister intent to see if it might help clear up your issue.

 If you give the user the option of unregistering, then you would use 
 the same register routine again to get a new ID. If the user uninstalls 
 the 
 application, it also unregisters and you would need to get a new ID if 
 they 
 reinstalled. If neither of these two happen, I believe you don't ever have 
 to refresh the ID of the device.

 Are you running into a problem?

[android-developers] finishActivity: (popping two activities simultaneously?)

[John Goche]

Hello,

I have come across the following scenario: I have an activity A which
needs to launch activity B to make a selection. The selected value
eventually needs to be passed back to A, but before that happens,
selecting the value from activity B launches another activity C. When
a selection is made on activity C both selected values from B and C
are passed back to A.

So now I am wondering what the best way to code this is. Do I use
finishActivity() or just call finish() in activity B when its
onActivityResult()
is called? Suggestions welcome. Basically I would like to rid myself of
both popup windows when a selection in the latter is made.

Thank you for your input,

John Goche

Thank you all for your replies,

Your answers were helpful and made me decide not to
rely on the hardware button being there. I will have to go

[android-developers] Re: How to obtain A-GPS data via Android phone

[Kenneth WON]

Hi, lbendlin,

Yes, I know, the GPS is not designed for indoor use.

In some case, such in subway or tunnel, the GPS cannot functional, so
I need to use A-GPS to obtain the location instead of using GPS.
(Someone tell me that the A-GPS can be functional in indoor
environment. Please let me know if I am wrong).

The big point is I have no idea of obtaining the A-GPS position.


Thanks and Regards,
Kenneth Won

Re: [android-developers] Android with Python

[Kristopher Micinski]

Python isn't usable for real application development, at least at this
point.  If you want to write production quality apps, you'll need to
use the sdk, in java.

Apps aren't written solely in Java, but they are not written in C#.
The reason apps are written in java is because the vm runs bytecode
translated from Java.  You can also use C/++, but it's not an excuse
for not learning the Java SDK.

While it is possible to write some simple things using SLA (python),
you won't get too far with it.

[android-developers] Re: How to obtain A-GPS data via Android phone

[lbendlin]

Sorry, A-GPS has nothing to do with indoor navigation. All it does is speed 
up the initial lock because it can tell the receiver which satellites to 
expect (normally the receiver has to listen and build up the ephemeris by 
itself).
 
what you probably want are alternative solutions like DGPS (very 
expensive), NorthStar, or WiFi, WiFi would be a good candidate but there is 
absolutely no standard, and you would have to come up with the solution 
yourself.

[android-developers] Re: finishActivity: (popping two activities simultaneously?)

[lbendlin]

use startActivityforResult
 
and then listen to the resultCode in onActivityResult. for example "OK" 
could mean "stay on B when C has finished", and "Cancel" could mean "finish 
B too when C is done."

[android-developers] Re: Android with Python

[raduq]

So, in the end for advanced development I will have to use the Java
SDK. I have started out to make some simple apps with the Java SDK but
now after being noticed in the e-mail to read about Python I started
looking up what Python can do for Android apps, but haven't found much
info. Have you developed apps for Android in Python?

Re: [android-developers] Custom preference (slider) on a non-touchscreen device - how to convert left/right keys to slider change?

[lbendlin]

that's a bit grand for such a small user base. I ended up going with the 
inelegant but simple onClick solution iterating up and down the slider. 
Good enough as the preferences are not changed often.

I haven't "developed apps" but I have "played around with the SLA
(Scripting Layer for Android)."  In the end, if you want to play with
apps and maybe get something up and running prototype wise, it might
be a nice idea to use Python.  But for real production apps, and just
to learn about how the system *actually works* you would be remiss not
to get a fairly good understanding of the SDK.

[android-developers] Library srec_jni

[DulcetTone]

Where does this reside, in a format compatible with
System.loadLibrary() on the host computer (say, when it is being used
within the simulator)?

I see a libsrec_jni.so , but regular non-Dalvik Java code on my own
machine does not recognize it as something good for loadLibrary() or
load().

There MUST be a version of it somewhere, as it can be used from within
the simulator.  I am trying to figure out if that one is suitable for
use from normal Java apps, and -- if not -- how to build one that is.

[android-developers] Camera autofocus

[kypriakos]

Hi all,

I am getting the famous Failure [INSTALL_FAILED_MISSING_FEATURE] on an
Optimus LG 350P running Froyo (2.2.1). Checking the logging I see the
following:

E/PackageManager( 1376): Package org.mortbay.ijetty requires
unavailable feature android.hardware.camera.autofocus; failing!

What ??? The phone does have the autofocus feature on the phone. And
the app works
fine on the G1 ... would this mean that the autofocus is not "enabled"
hardware wise
on the device? Or is something else missing from the app's point of
view?

Thanks
