[android-beginners] Intent between 2 APK (different projects)?
Hello, I have two different android projects and would like to communicate a data stream between those. Is this possible with intents? I can only find example code to communicate within the same project. I would appreciate if someone know where to find some example code.

[android-beginners] Possible to send object via intent extras?
Hi, Is it possible to send an object via intent extras? I would like to send a pipeoutputstream to another APK (project via extra). Can I save an object to a bundle somehow?

Is it possible to send an object via intent extras? I would like to send a pipeoutputstream to another APK (project via extra). That is not possible. Can I save an object to a bundle somehow? Only if you can make it implement Parcelable or Serializable. If you need to expose some sort of stream, you will need to wrap the stream in some API that you expose to other applications via AIDL. -- Mark Murphy (a Commons Guy) http://commonsware.com Android App Developer Books: http://commonsware.com/books.html --~--~-~--~~~---~--~~ You received this message because you are subscribed to the Google Groups Android Beginners group.

[android-beginners] Re: A problem about application die unexpected.
someone can correct me if i am wrong, but i believe this is normal and
expected. android will stop your process when memory becomes low. to
verify this, put some debugging in your onPause(), onStop(),
onDestroy() methods. if those are being called, it the OS stopping your
process.

[android-beginners] Sprite Type Images Guy
Hey Guys, I was wondering if there was any sort of sprite support built into Android? Currently, I've got TONS of tiny icon-ish files (40x100, 90x90) and it's taking up a considerable amount of space. The first set is around 272KB total and the second is 432KB. When I sprite and optimize the images, it comes out to 88KB and 152KB, a savings of around 60%. Also, that 450kb just inflates the size of my apk dramatically. Is there any way to do Spriting? I use the icon currently in Images in both Grid and ListViews. Thanks! Evan --~--~-~--~~~---~--~~ You received this message because you are subscribed to the Google Groups Android Beginners group.

[android-beginners] Re: Poor performance on my file loader (code optimization help!)
Thanks for the reply. I think your suggestion of going binary is one
of the better ones I had considered. Especially because I can avoid
the parseFloat() calls altogether using this method.
As for the quaternion vs axis/angle, I had thought I HAD to translate
them originally (I found out later with more research that I just had
to use the more complicated matrix math rather than simple glrotate
and gltranslate calls if I didn't). I don't suppose you could direct
me to a tutorial or good description that will help a 3D rendering
newbie like me use the quaternions? If it really is better/faster, I
want to go that route rather than finding out later I should have.
I'm still looking for any additional suggestions on what particular
parts of the code might be killing my load times, although I'm sure
switching to binary and not using acos and sqrt will help quite a bit.
Thanks,
Glen

Ugh, why oh why are you transforming quaterninions to axis/angle
representation? Quaternion interpolation is easier, and gives better
result (you will also save a lot of time on calculations).
About performance, if it's possible (eg. you are not downloading the
scene files from network or smth), write a small utility that will
convert text file to binary representation offline, and then read the
binary files on android. Also try to minimize number of allocation
during file loading.

[android-beginners] Re: Poor performance on my file loader (code optimization help!)
Fadden, Sorry, I missed your reply when I responded to Bart! I tried to find significant ways that I could avoid allocation, but the StringTokenizer is the main thing that I'm calling 'new' on and I didn't see any way to avoid doing that for every line. Your suggestion of using regexs for a parser kind of threw me off, because I didn't even see that as a possibility. I'll have to look into that and see what you mean. I also didn't know the G1 didn't have floating- point hardware. Will this likely be the case for other android phones in the near future? This information combined with Bart's suggestion to stick with quaternions means I'll very likely be removing those calls to acos and sqrt entirely. Also, thanks for the links.

For a parser using regular expressions, you avoid the cost of recompiling the RE. acos() and sqrt() are not especially fast; sqrt () in particular, since the G1 lacks floating-point hardware. You can get some sense for where the time is going with the method tracing facility: http://developer.android.com/guide/developing/tools/traceview.html [...] I could even do something as drastic as performing this load in a separate app (before distribution) and somehow exporting the resulting object (KdfAnimation) that could more easily be picked back up (this would work in C, but I'm doubtful Java would allow such low-level memory copying).

I have subclassed Gallery and modified the onFling method to add in the ability to swipe up on any given view in the gallery. Some users have been complaining about the Galleries being sluggish. After looking into it a little bit it, this is what is happening: - The app launches - On any of the gallery views, swiping left or right initially has some hiccups (it is not a smooth scroll) - After every item has been displayed on the screen at least once the hiccups are gone I assume this is because the Gallery View only stores information for what is currently displayed on the screen and that it also caches the information for items that have been viewed but are not currently visible (hence the smoothness after scrolling through everything). I could not find anything in the SDK docs or the Dev Guide. The adapter is a very simple extension of BaseAdapter... Not very different from the Gallery example in the Dev Guide.

[android-beginners] onKeyboardActionListener vs onKeylistener
Hi, I am new to Android, and am writing an app which has 2 EditTexts (Let's call them A and B) and whenever I hit any key in A, it is automatically copied to B. For example, if I type HELLO in A, it will copy each letter into B. I managed to get this to work perfectly with the setOnKeyListener(). However, in the emulator I found that the virtual keyboard did not respond to this listener the same way. For some weird reason, the number keys in the Virtual Keyboard (0-9) responded to the onKeyListener but none of the others did. After doing a Google search of my issue, I found some people with similar problems, but no real solution. I realized there is a KeyboardView.OnKeyboardActionListener which listens for inputs from the virtual keyboard. However, I have no idea how to use this in my edittext field. I would appreciate some sort of help with this matter. Thanks! --~--~-~--~~~---~--~~ You received this message because you are subscribed to the Google Groups Android Beginners group.

[android-beginners] Re: onKeyboardActionListener vs onKeylistener
Thanks for the reply. If I type HELLO and hit the back button, only O
gets copied into box B. It's weird. Here is the relevant part of my
code:
@Override
public void onCreate(Bundle savedInstanceState) {
super.onCreate(savedInstanceState);
setContentView(R.layout.virtualkeyboard);
final EditText boxA= (EditText) findViewById(R.id.boxA);
final EditText boxB= (EditText) findViewById(R.id.boxB);
boxA.setOnKeyListener(new OnKeyListener() {
@Override
public boolean onKey(View v, int keyCode, KeyEvent
event) {
// TODO Auto-generated method stub
if(event.getAction() == KeyEvent.ACTION_UP)
{
//copy text from box A to B
}
return false;
}
});
Now just to repeat my problem, the above code works perfectly when I
use a physical keyboard, or the emulators hard keyboard. It is only
when I use the virtual(soft) keyboard does it not work. I saw some
posts online about using setOnKeyListener instead. But I do not know
how that works since it is not a method for EditText.

[android-beginners] Re: Xzing Barcodescanner without Intent
So well, yess, people preffer using intents because it is much easier! but the google barcodescanner must be installed, otherwise you have to handle the exeptions (when you start the intent put it into a try and if it does not work let a dialog pop up or so...) and yesss, something you should know about intents, sometimes it doesn't handle the orientation changes right! ok, i just found out, that the emulator does not support the android market, so what you can do is look in some filesharing sites and download the apk and then upload it to some website, and then install it via the webbrowser onto your emulator. thats the only thing, i could think of. to your problem of the barcode scanner, it is going to be hard to get that to work isn't there something black and white, when you start the camera on the emulator? couldn't you maybee just change that picture to a barcode one? but i have now idea how you would do that... sorry if i couldn't help you as much as you would prefer... regards joe On 22 Sep., 20:57, wahib haq wahib.t...@gmail.com wrote: hi joe.

[android-beginners] Re: Poor performance on my file loader (code optimization help!)
Hi, As for the quaternion vs axis/angle, I had thought I HAD to translate them originally (I found out later with more research that I just had to use the more complicated matrix math rather than simple glrotate and gltranslate calls if I didn't). I don't suppose you could direct me to a tutorial or good description that will help a 3D rendering newbie like me use the quaternions? If it really is better/faster, I want to go that route rather than finding out later I should have. Quaternions aren't faster (well ok nlerp can be) but they are better at least for interpolation, sice you are clearly reading keyframing data, thus I assumed that you will interpolate it sooner or later therefore transforming them to axis/angle looks a bit redundant (since usually rotation is interpolated with cubic quaternion interpolation aka. squad). If yor some basic info about quaternions you can check this old (very) flipcode FAQ: http://www.flipcode.com/documents/matrfaq.html (this is really basic so may be a bit too basic :)) After bit searching I also found this: www.itu.dk/people/erikdam/DOWNLOAD/98-5.pdf looks ok to me And of course if you have Foley, van Dam CG: Principles And Practice book.

[android-beginners] coarse versus fine location provider
The MapView demo application sets the ACCESS_COARSE_LOCATION permission for wifi or cell location. Should a MapView activity also set the ACCESS_FINE_LOCATION permission to enable GPS location providers or is that permission also implied by setting ACCESS_COARSE_LOCATION? If both permissions are set and both settings are enabled will MapView prefer the fine (over the coarse) location provider? And will MapView sense a change in the availability of GPS?
