[android-beginners] Re: Camera Button Broadcast Receiver Problem...
Works like a charm! I have another question now. For devices that don't have a camera button (e.g. T-Mobile MyTouch and others) would it be feasible/ok to use the SEARCH_LONG_PRESS broadcast and do the same thing with that button instead? This is what I currently have but I can't test it... receiver android:enabled=true android:name=.CameraLaunchReceiver intent-filter android:priority=1 action android:name=android.intent.action.CAMERA_BUTTON / action android:name=android.intent.action.SEARCH_LONG_PRESS / /intent-filter /receiver Thanks, Justin -- There are only 10 types of people in the world...

Just have a simple receiver to receive the same intent as the camera that is: android.intent.action.CAMERA_BUTTON In that receiver class start your required activity as required. And, in the corresponding AndroidManifest.xml of your application declare the receiver as below: receiver android:name=*.TestReceiver* intent-filter android:priority=*1* action android:name=*android.intent.action.CAMERA_BUTTON */ /intent-filter /receiver The priority field tells Android to first choose the activity with the higher priority. I have used a very large value. Maybe even a smaller value will work. Also, in your receiver in the first line of your onReceive itself add the following line: abortBroadcast(); This will set a flag to abort the broadcast so nobody else will receive it after you. So, by setting the priority you are telling Android to choose your receiver first and by abortBroadcast you are cancelling the broadcast for Camera so it wont open at all. Hope this helps.

As an example, I have used an application called Task Switcher. I don't know how the developer does it, but he provides a setting that makes his app (and only his app) launch when the camera button is pressed. He lets the user know what will happen and verifies they want to proceed. I found this ability very useful and handy. I am developing an application very similar to Task Switcher and want to provide the same option to launch my app from the camera button. I would just prefer that the default camera didn't launch before my app... It makes it look like my app launched the camera and then itself and is very unprofessional-looking. Again, if any one knows how to do this, I would be very grateful.

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] Re: Empty EditText Causing force closes
Well, I got it working but I'm pretty sure there is an easier way to
do it. I basically just add a string variable containing 0, check to
make sure the string coming from the EditText isn't equal to 0, and
then parseInt the string and divide it by 10 to get the original
number. If anyone knows of an easier way to get this done that would
be great!

It's also always good to point out best practices to a poster that violates them, because they are otherwise left wondering why they get no answers to their questions. Mark is definitely not the only subscriber on this list who ignores cross-posters or people who re-post the same question within hours of the last one. Anyway, another option in addition to Mark's suggestion would be to block the startActivity call whilst your AsyncTask is running.

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!

[android-beginners] Microphone disabled by audio adapter?
Just started using my ADP1 in the car; with an HTC audio adapter, I can connect a line from the phoen to the car stereo. Works great for music, but when I tried to use the phone in speakerphone mode, the internal microphone was disabled. Is there any work around for this? The HTC pinout has a microphone input, so I guess plugging an audio adapter in automatically disables it. When I use the HTC headphones that came with the phone, I am still able to use the phone as a phone, without unplugging them. --~--~-~--~~~---~--~~ You received this message because you are subscribed to the Google Groups Android Beginners group.

Although this person was able to kill -9 his emulator. Still, it might be different symptoms for the same bug... Is there a particular reason why you're using such an outdated version of the SDK? I'm a tad suspicious of the reliability running a 1.5 AVD against a 1.1 emulator, it might be fine, but if you're having problems it might be worth downloading the latest SDK to eliminate the possibility of compatibility problems.

[android-beginners] Re: Poor performance on my file loader (code optimization help!)
Is there a reason to why you use a LineNumberReader? I would instead
use a BufferedReader, that will probably improve your performance.
I don't know anything about the dataformat in the file, but there
probably is a much faster way to parse it than using all those
StringTokenizers (or regexp even if that might be faster). I would
also try to parse the file without mark and reset.

Hello!
I'm fairly new to both Android and Java (pretty experienced in C/C++),
and (stupidly, perhaps) took on a big project. In it, I need to load
information about 3D models and their respective animations from a
text file (proprietary file format based on PSK/PSA).
The loading process on a sample (1000+ line) file is abysmally slow
(more than 4 minutes). The good news is that there are lots and lots
of ways I can improve it. What I'm hoping to find out here is if
there's anything in *particular* in my code that is very inefficient
that I can change. Don't worry about offending me, I know this is
amateur code here.
Some possible causes for the slowness:
- Extensive use of parseFloat()
- Creating new StringTokenizer for every line
- Inefficiencies in for() loops (not caching as necessary?)
- Repeated use of the acos() and sqrt() functions
I'd like to find out from you gentlemen (ladies) what you think is the
major thing eating up my time here. If there's some tool I can use to
find out what lines of code are taking up the most time that'd be
ideal. I'm open to any possible solutions. The file format can
change (and probably will). 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).
One final note is that the action loading section of this code
occupies about 3/4 of the files being loaded (so this section may be
more important to optimize).
Loader Code
public class KdfLoader {
public static KdfAnimation load(String file) throws IOException {
KdfAnimation anim = new KdfAnimation();
FileInputStream fis = new FileInputStream(file);
String line = [start];
LineNumberReader lnr = new LineNumberReader(new
InputStreamReader
(fis));
int boneNum = 0;
try {
for (line = lnr.readLine(); line != null; line =
lnr.readLine()) {
if (line.length() 0) {
if (line.startsWith(numbones)) {
// Ignore it for now
}
else if (line.startsWith(bone)) {
// Bone define
StringTokenizer tok = new
StringTokenizer(line);
KdfBone bone = new KdfBone();
// Toss out bone
tok.nextToken();
// Set name
bone.boneName = tok.nextToken();
if (boneNum == 0) {
// Root bone. Ignore
children and parent id in file
bone.parentId = 0;
bone.parent = null;
// ignore numchildren x
// ignore parentid x
}
else
{
// ignore numchildren x
tok.nextToken();
tok.nextToken();
// ignore parentid text
tok.nextToken();
bone.parentId =
Integer.parseInt(tok.nextToken());
bone.parent =
anim.allBones.get(bone.parentId);

[android-beginners] Re: onKeyboardActionListener vs onKeylistener
Hi Balwinder,
That is pretty much what I'm doing. I'm running 1.6. I guess it's
working for me as well that way, but why do I have to hit the back

this would be kind of frustrating.

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.

[android-beginners] java.util.prefs.Preferences doesn't work on device?
Hi! My simple app needs to permanantly save its state before being destroyed. I use something like this: private static final Preferences prefs = Preferences.userNodeForPackage (WordChoice.class); Now it seems that after experimenting a while on my g1 device, it seems that preferences are sometimes cleared when the application stops, from my experience this happens at random and there is a roughly a 50% chance that preferences will be cleared. This does not happen in the emulator, and certainly should not in the Java world as far as I know since preferences are permanent type of storing data. Is there a way to use java.util.prefs.Preferences on Android platform without risking clearing the prefs every time the app is stopped?

this is the problem: there are 5 EDITTEXT boxes. the value that the user enters into FIELD1 needs to be retrieved in to a variable called FIELD1_RETRIEVED. if the user enters 135.98, that number is used in the calculation process. once FIELD1 is entered, the CALCULATE button is pressed. WHATEVER those value might be the remaining fields(FIELD2, FIELD3, FIELD4 AND FIELD5) need to take on those values. all the R.id.FIELDX are an INTEGER. so how to do this is getting abit overwhelming, i realize that it isn't all that hard to do, but at this time, very frustrating. anyone who could lend so code samples of how to read what a value is, and put a result into a EDITTEXT field would be appreciated. thanks to all, rc3375 --~--~-~--~~~---~--~~ You received this message because you are subscribed to the Google Groups Android Beginners group.

[android-beginners] ImageAdapter Help
I'm working on a program that generates dice, lots of dice. I finally
found out how to make an adapter to display an image dynamically, but
now I have a new problem. The dice that are generated/displayed by the
Adapter change if they scroll off the screen. Basically every time
each die image moves into view it is re-randomizing what die it needs
to show. I also need it to log the die results to a separate file, but
I don't know where to stick that code, seeing as it would add dice to
the list every time a die is re-drawn.
This is my current code:
public View getView(int position, View convertView, ViewGroup parent)
{
ImageView imageView;
if (convertView == null) {
imageView = new ImageView(mContext);
imageView.setLayoutParams(new GridView.LayoutParams(75,
75));
imageView.setScaleType(ImageView.ScaleType.CENTER_CROP);
imageView.setPadding(1, 1, 1, 1);
} else {
imageView = (ImageView) convertView;
}
Random RollDie = new Random();
Die1 = RollDie.nextInt(6);
Die1Copy = Die1;
if(((Die1Copy += QuickShoot.BSFinal) 6)) {
Die1 += 6;
}
imageView.setImageResource(DieResult[Die1]);
return imageView;
}
// references to our images
private Integer[] DieResult = {
R.drawable.die1, R.drawable.die2,
R.drawable.die3, R.drawable.die4,
R.drawable.die5, R.drawable.die6,
R.drawable.die1under, R.drawable.die2under,
R.drawable.die3under, R.drawable.die4under,
R.drawable.die5under, R.drawable.die6under
};
}
If anyone knows how I can make it generate a Die for a set position
and then not redraw please let me know you will save my life!

[android-beginners] Re: Scroll image like a WebView
The idea is that I want to use standard UI designs for things. I have a large scrollable area, and I want people to know it's scrollable because there's the same scrollbars that they see in other applications. It feels silly to have to rebuild the scrolling functionality from scratch. It already exists in another component, and really should exist in a primitive form, but if I have to rebuild that functionality from scratch, well, I guess that's what I have to do. I just hope that in a future SDK release, someone will realize that not having this particular bit of functionality outside of the WebView widget is unnecessarily limiting.

This is for an Android port of Nethack: http://www.nethack.org/ For reference, here's an image of the WinCE port: http://images.google.com/imgres?imgurl=http://freewareppc.com/images/... There's a large map, the tiles are 16x16 pixels, and scrolling in both directions is absolutely required. This is really something that should be easy in Android, but I have no idea how to do it. Try using the 2D graphics API (Canvas and SurfaceView). I suspect there are few, if any, games on Android akin to Nethack that attempt to use the widget API (ImageView and scrolling containers). I know that Ed Burnette's book _Hello, Android_ covers this API, albeit for a Sudoku game rather than something like Nethack. One of these days, I'll have to learn this stuff myself... -- 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.
