[android-developers] Re: android bluetooth
As far as I can see, Android does not currently support playing sound (beeps or other) through a mono (SCO) BT headset. I believe that BT stereo (A2DP) headsets work, though. Have not tried. You might want to check this thread for more info: http://code.google.com/p/android/issues/detail?id=7906 As for getting info on headset button activations in your app, I believe that this requires support for the AVRCP profile. Again, this is commonly seen for stereo headsets, but not for mono. I don't think that the Android BT stack supports AVRCP. This wikipedia article gives a good intro to BT profiles, if you need that: http://en.wikipedia.org/wiki/Bluetooth_profile If you manage to get it to work, be aware that the various manufacturer's interpretation of the BT spec tend to vary a bit... In other words: I'd recommend to test the functionality with every headset that you wish to claim supported by your app. Good luck!

You did not get your point across properly. You are doing better in this post, though, despite the disappointing typo of '[oint' for 'point'. But if you do know that the beep is at headsets[sic] control, why you even asking where it is? That makes no sense. The truth of the matter is that the Bluetooth spec does not mandate the beep. The implementer may chose to do it in the headset software, as it is the only choice that makes sense: otherwise the user gets no audio feedback to know that pairing just happened. The only feedback that the Android application gets is that now the headset is listed in the list of bound devices returned by getBondedDevices(). That is, you can sense when the headset was paired by polling getBondedDevices(), but you cannot cause the beep, nor can you sense when the headset does its own beep. You can only rely on what the headset manufacturer chose to implement in their own Bluetooth code.

Your questions seems to strongly imply you have not studied the basics of how to do Bluetooth (whether on Android or not). Specifically, the beep you are interested in controlling is under the headset's control: it is NOT controllable from Android. Nor should it be, so don't wait for it to be added in a future version.

[android-developers] Re: Camera preview not restarting after picture taken
Hi Mark, I've looked at your code, thanks for the link. In my app I'm using the new addcallbackwithbuffer and setpreviewcallbackwithbuffer methods. I'm using them to capture preview frames and process them. I think there may be a bug because the camera take picture routine is stalling. I suspect memory issues, but nothing is obvious in logcat.

You are welcome. Now as for your handset beep: there is no API in the android.bluetooth packet for generating the headset beep on a remote device.

You did not get your point across properly. You are doing better in this post, though, despite the disappointing typo of '[oint' for 'point'. But if you do know that the beep is at headsets[sic] control, why you even asking where it is? That makes no sense. The truth of the matter is that the Bluetooth spec does not mandate the beep. The implementer may chose to do it in the headset software, as it is the only choice that makes sense: otherwise the user gets no audio feedback to know that pairing just happened. The only feedback that the Android application gets is that now the headset is listed in the list of bound devices returned by getBondedDevices(). That is, you can sense when the headset was paired by polling getBondedDevices(), but you cannot cause the beep, nor can you sense when the headset does its own beep. You can only rely on what the headset manufacturer chose to implement in their own Bluetooth code.

When I check, Name did contain the correct value.
I remember array starts with [0] so I create another counter call i

Somehow lv_arrr still contain null. Why is that so?

[android-developers] Re: How to detect when bluetooth is turned on by user?
Please read http://developer.android.com/reference/android/bluetooth/BluetoothAdapter.html and notice that getDefaultAdapter() returns a real Adapter only if Bluetooth support exists. If Bluetooth support exists, but is turned off, then getState() returns STATE_OFF. At least that is the way it is supposed to work: I have vague memories of getDefaultAdapter() returning null when the adapter was turned off on my T-mobile G2. But I can't vouch for that, and am not taking out the time to test for it now. There is a broadcast action you can wait for: ACTION_STATE_CHANGED.

[android-developers] Problem with password based encryption of image files
Hi,
I'm trying to encrypt image files on Android with password based
encryption. To save the encrypted image I just do this:
FileOutputStream fos = new FileOutputStream(thumbnailFile);
CipherOutputStream cos = new CipherOutputStream(fos, encryptCipher);
Bitmap thumbnail = Bitmap.createScaledBitmap(bm2, 140, 140, true);
thumbnail.compress(Bitmap.CompressFormat.JPEG, 80, cos);
and to read it, this:
FileInputStream fis = new FileInputStream(f);
CipherInputStream cis = new CipherInputStream(fis, decryptCipher);
Bitmap b = BitmapFactory.decodeStream(cis);
but the Bitmap ends up as null. The code works when I bypass the
encryption; that is when I use the File(Input|Output)Streams rather
than the Cipher(Input|Output)streams.
My Ciphers are created as follows:
public void initCiphers(char password[]) {
PBEKeySpec pbeKeySpec;
PBEParameterSpec pbeParamSpec;
SecretKeyFactory keyFac;
byte[] salt = {
(byte)0xc7, (byte)0x73, (byte)0x21, (byte)0x8c,
(byte)0x7e, (byte)0xc8, (byte)0xee, (byte)0x99
};
int count = 20;
pbeParamSpec = new PBEParameterSpec(salt, count);
pbeKeySpec = new PBEKeySpec(password);
try {
keyFac = SecretKeyFactory.getInstance(PBEWithMD5AndDES);
SecretKey pbeKey = keyFac.generateSecret(pbeKeySpec);
encryptCipher = Cipher.getInstance(PBEWithMD5AndDES);
decryptCipher = Cipher.getInstance(PBEWithMD5AndDES);
encryptCipher.init(Cipher.ENCRYPT_MODE, pbeKey, pbeParamSpec);
decryptCipher.init(Cipher.DECRYPT_MODE, pbeKey,
pbeParamSpec);
}
catch (Exception e) { Log.v(tag, e.toString()); }
}
I don't get any exceptions.
There is obviously some problem with using Cipher(Output|Input)Streams
with the android functions for encoding and/or decoding images, but
since those functions are opaque and there are no exceptions, its hard
to know what it is. I suspect it has to do with padding or flushing.
Any assistance would be gratefully appreciated.

[android-developers] Re: Problem with password based encryption of image files
Also -- if I use NullCipher as the encyption and decription ciphers
for Cipher(Output|Input)Stream, it works.
Here's a theory: since PBEWithMD5AndDES uses CBC mode with
PKCS5Padding, it could be that Bitmap.compress is flushing its
OutputStream where it should not -- which would be at any point prior
to closing the stream. Ordinarily this would not create a problem, but
with a CipherOutputStream using a padding cipher, it would cause extra
padding bytes to be inserted in the output. I supposed I could try to
find the the source code for Bitmap.compress, to see if this is in
fact what is happening ...

[android-developers] Fill-remainder layout?
I'm used to Java Swing layout managers (especially GridBagLayout), and I haven't been able to figure out to do something relatively simple with the Android layouts. I want to have a bar of controls at the top, and another bar of controls at the bottom. Then I want to have an area in the middle that uses whatever space is left over. (mainly for graphics drawing) I'm currently using a RelativeLayout with 2 Linear layouts for the top and bottom. I just haven't been able to find a combination of layouts that lets me have a view just fill the middle remainder area. I'm trying to start with a simple background color on a view in this area. if I use wrap_content it's way too small. If I use fill_parent it fills the ENTIRE parent, including the areas used by the 2 bars of controls. How do I define something to just fill the remaining space in the middle? -- You received this message because you are subscribed to the Google Groups Android Developers group.

[android-developers] Re: Fill-remainder layout?
layout_weight=1.0 will cause the view to fill any remaining space. If the view in the middle might be bigger than the available space it will push the bottom row off however. There's a solution for that. Pent -- You received this message because you are subscribed to the Google Groups Android Developers group.

[android-developers] Re: Android - InputStream SQLiteDatabase - How to read more than one xml file
If you're doing this to load up the DB, it's simpler/faster to just
include the pre-built DB in your app and then copy it to the right
place once installed. (Be sure to name it .jpg or some such if larger
than 1M to avoid the compression mess.)

[android-developers] Re: Image doesn't appear from sqlite
What's varying? The data won't be read back into the same address,
but into a new byte array, and [...@ is just a byte array at a
certain address. Dump a few bytes of the arrays (eg, first and last
10) so you can compare their contents.

[android-developers] Re: Cannot define a float as a resource?
You could always use floatToIntBits/intBitsToFloat. But keep in mind that the resources are actually char data anyway, and you might as well just use parseFloat on a String (though then you have to catch NumberFormatException).

[android-developers] Re: Image does't appear from sqlite
The addresses vary because they're different objects. You need to
dump some of the actual byte arrays to see if they're different. You
could even write code to compare input and output.

JSON is blazingly simple. You can write your own parser in a day using about 600 lines of code. (Another 300 lines of code and maybe 3 hours to write the encoder end.)

Re: [android-developers] Re: Image doesn't appear from sqlite
+0.02 - this code:
public void insertlistNews(String city,*byte[] newsImageUrl*, String
publishDate, String expiredDate){
[snip]
+ VALUES (' + city + ',*' + imageUrl + '*,' + publishDate+
',' + expiredDate'););
appends a byte[] to a String.
This is the same as appending String.valueOf(imageUri), which calls
byte[].toString, which *does not* return the contents of the array, but
rather its type marker and address - which does look like [...@437c1338
and so on.
If you want to insert byte[] values into the database, use one of:
- SQLiteStatement and bindBlob(int index, byte[] value)
- DatabaseUtils.InsertHelper and bind(int index, byte[] value)
- ContentValues, put(String key, byte[] value), and SQLiteDatabase.insert()
If you mean to insert the URL as a string, make sure you use a String
variable for the URL to build your SQL statement.
Perhaps you are trying to do both (your code sample uses two different
variable names: newsImageUrl and imageUrl), so do each one as described
above.

What's varying? The data won't be read back into the same address,
but into a new byte array, and [...@ is just a byte array at a
certain address. Dump a few bytes of the arrays (eg, first and last
10) so you can compare their contents.

[android-developers] Re: Split screen om android
Indeed, this is not the group for info about how to do this. However, before you go, I'd like you to minimize the set of changes you're thinking about. This group is about programming using the SDK, so I think it's appropriate to discuss what we SDK users would like to see. (Up to a point, anyway). While I'd like to see support for multiple windows, I'd also like to see it involve as few changes to the SDK, and be as upward-compatible for older programs, as possible. And, of course, I'd like the user usage model to be as natural for users as possible. Android already supports multiple activities being visible. The tricks I see needed are: 1) Launching an app using a particular window area. Somehow the home screen app needs a hook here, and you need a policy for when to launch activities into the other vs this by default. I think the default policy should be same app, same window, and that this should be overridable via a value in the intent. 2) Figuring out what the back button should mean here. I think you may only need a single activity stack here. Even if the user has been alternating between screen areas, it would just remove the most recent activity. The long-press Home key could be used to bring up activities in either window and give the user the ability to reorder and select which activities are shown simultaneously. The one enhancement here I'd suggest would be to show which screen portion they're currently displayed on -- and allow the user to drag them to the other side. 3) Applications need to be able to discover which area they are in, and what areas are available, and their geometric relationship. They need this to be able to be able to fill in the intent with the suggestion of where to launch, and they may need to know where they are in order to animate transitions appropriately. Or it may be able to automate that with a standard transition when one activity launches another that ends up in a different window area. In fact, it may be essential, when handling older apps, to suppress the animations supplied and supply something more suitable, as, say, a right-to-left slide out/slide-in, will look completely bizarre if the starting activity is on the left, and the ending activity is on the right (or worse, bottom-left, top-right).

[android-developers] Recycling MotionEvents
Hi there. Have a custom gesture class that detects 'buildup' gestures
for a drawing program. In the class, I test the current MotionEvent
and in ACTION_MOVE, set a private field mCurEvent to the current
event, process it and then set a private mPrevEvent to the same event
so that on the next ACTION_MOVE, I can compare the current and
previous events to determine distance moved, etc. Example:
switch (ev.getAction()) {
case MotionEvent.ACTION_MOVE:
mCurEvent = MotionEvent.obtainNoHistory(ev);
if (mPrevEvent != null) {
compare the two events
}
mPrevEvent = MotionEvent.obtainNoHistory(ev);
break;
Everything works fine, until I start trying to clean up the code
and .recycle() MotionEvents on ACTION_UP, ACTION_CANCEL. Recycling
the current and previous event frees up resources, but on the next
touchdown and move, mCurEvent and mPrevEvent are being allocated to
the exact same object address space, meaning that setting mCurEvent =
MotionEvent.obtainNoHistory(ev); is also setting the mPrevEvent
variable that shares that points to the same object...
I'd like to recycle the events as there could be MANY created with
lots of ACTION_MOVE events... but doing so seems to have these
results.
Any strategies or recommendations?
Thanks,
Paul

Re: [android-developers] Re: Fill-remainder layout?
Thanks, I did finally get it done with a relative layout. The only problem I ran into was making sure there were no forward references in the id's. (Which is why your example had the middle layout at the bottom.) I was just trying to modify my existing layout, and it had the middle in the middle! :-) I had to move it to the bottom of the file so it could reference the bottom panel in it's layout_above entry.

You don't *have* to declare an id where it's first used to identify a view (as opposed to referring to it). It's perfectly legal to do this: View *** note the plus sign here *** layout_above=@+id/anchor_view .../ View id=@id/anchor_view .../ or even this: View *** note the plus sign here *** layout_above=@+id/anchor_view .../ View *** and here *** id=@+id/anchor_view .../ Note that view declaration order in XML is the initial Z-order (top-to-bottom is back-to-front), so sometimes forward references are necessary. -- Kostya Vasilyev -- WiFi Manager + pretty widget -- http://kmansoft.wordpress.com -- You received this message because you are subscribed to the Google Groups Android Developers group.

[android-developers] Re: Using Ant script '.apk' file is not getting created
I don't see anywhere that you're invoking the resource compiler, or
including its output in the compilation. That's what the compiler is
complaining about -- the 'R' class is defined by the resource
compiler, and needs to be compiled together with the rest of the
application.
Instead, you're trying to compile it AFTER the rest of the application
(that's your second invocation of 'javac'), and I don't see anywhere
that you're actually generating it anyway.
I don't recognize just how you generated this file, perhaps this is
the output of Eclipse's import facility. In any event, it doesn't
appear to be what you want.
Wny not let the 'android' command set up your build files, as per the
documentation:
http://developer.android.com/intl/de/guide/developing/other-ide.html
Yes, you can do this even though you're using Eclipse.

If not, where could you define scope so that it would be seen in
both methods?

Re: [android-developers] How to detect click on complex images/polygons
The first thing that comes to mind is java.awt.Polygon.contains(). I've used it, but obviously with AWT and also with polygon data from http://www.census.gov/geo/www/cob/ One approach then would be to find a similar Android polygon class that can be used to draw and hit test your map and a way to convert the map's bitmap image into a vector image, or at least a vector overlay for the bounds hit test. There are some ways you can get vector from a bitmap. I've used Visio by putting the image on one layer and tracing out the vector shapes in another layer, then writing some VB to export the shape vector data to XML. Do you have Adobe CS? That might have some tools for converting bitmap shapes to vectors. Or perhaps the image was originally authored with vectors? There may also be some clever ways to do hit tests on the color values in the bitmap. -- You received this message because you are subscribed to the Google Groups Android Developers group.

Re: [android-developers] Suggestions on sharing code between standard Java Android
I don't have actual experience doing this in Android, but I can offer some suggestions from general experience with Java and software archtecture. How much can you exploit MVC? What part of the code is the View? How much of the code is the Model? If a large part of the code is the Model, that is the business rules, logic, data conversion, etc., then there's a good chance that with some refactoring, you can get that part of the code to run on Android after some refactoring. Unless the code was actually architected to run on different platforms - which it probably wasn't, blinded by the sirens of WORA - chances are there'll be some painful refactoring. BTW, is the existing code base covered with unit tests? That would help. My rule of portable code is: Code isn't portable until it's been ported. -- You received this message because you are subscribed to the Google Groups Android Developers group.

[android-developers] Re: Suggestions on sharing code between standard Java Android
I'd create a common CVS project and check it out into two different environments. It does take a little discipline to prevent the two copies from diverging, but if you check in/out on a regular schedule it should work. On Dec 23, 12:56 pm, Eric e...@alum.mit.edu wrote: We have a large, complex, Java client/server application that is deployed in Java Swing. We hope to leverage this codebase and reuse a lot of the client-side model, controller, and communication code in a new Android port of this application. Does anyone have thoughts on how best to do this (FYI, I use Jetbrains IDEA as my IDE, not Eclipse)? For example, several questions come to mind: - is it better to create a new IDE project for the Android project, or just add an Android module to the existing IDE project (I prefer the latter to take advantage of global refactorings). - if adding an Android module to the current IDE project, how does one best share lower-level Modules across Java Swing and Android? Things become very problematic because Android does not ship with the full standard JDK, and therefore code must be moved, refactored, or even deleted if it depends on JDK packages that are not available on Android. This means that for a pre-existing Util module to be shared across the platforms, we may have to create a new lower-level version of that Module that only depends on the packages that Android has available to it. - I've also found through experimentation that when I try to depend on a pre-existing module that has Jar dependencies of it's own, the Dalvik conversion process doesn't always successfully convert that Jar into Android format (possibly because it contains unsupported code). What's confusing is that the Dalvik conversion works on certain jars that contain unsupported code, but not on others. So the conversion process must be ignoring code that isn't referenced somehow. In summary, I've encountered a lot of problems trying to depend on third- party jars on Android, and I'm wondering if anyone else has the same problems, or suggestions? - another way to approach this is to copy the shared code into the Android project and give up the ideal of trying to share the code, and just maintain two distinct code bases (this is not at all ideal, but it may be the most painless route). - I have another specific question about the Dalvik VM conversion process. Exactly how does that process work? Does it strip out code that is unsupported on Android? For example, I had a JAXB generated file which referenced the import javax.xml.bind.annotation.* classes that are not available on Android. With my Android module SDK set to the main JDK, that code DID compile and DID get converted to Dalvik, despite the fact it references classes that are not available on Android. I did this by adding a dependency to another pure-java module that has the jaxb.jar as its dependency. Did the Dalvik converter actually convert the entire JAXB jar and put it onto Android, or did it just strip out the JAXB classes and references from the bytecode that are not available on Android? I'm very curious about how this all works, because the answer will have a significant impact on how we move forward on our project. We have a lot of code that is written to the standard JDK that we'd like to reuse on Android. The code certainly does references packages that are not available on Android, but we may not necessarily hit those code paths from inside Android. But if the system will automatically strip out the unavailable code paths for us, to allow us to reuse the same source code, that would be very beneficial.

The following test was with Nexus S lying flat on table with display up.

[android-developers] Basic String Array question :(
Sorry, if this is too basic and not entirely Android.. but android is
part java too, so I don't have to hop forum. I believe someone else
might encounter this too. I'm putting some statement in the Android
basically reading an xml file and cast the value into an array to be
use as listview but I encounter some problem. To keep thing simple and
readable, I simplify it as below:
String[] lv_arr;
for(int i=1; i11; i++){
lv_arr[i] = hello;
}
When I toast the value of lv_arr[i] it is null.
If I do this:
String[] lv_arr = {hello, hello, hello} + the for loop, I can get
the hello value when I do the toast.
but [3]-[10] is still null value.
Why is that so?

[android-developers] Help with animation
I have a LinearLayout with 2 vertical components: View1 View2 I would like to smoothly animate-in View1.

[android-developers] Re: Help with animation
I think View1 is always going to have an intrinsic height of its measured height for the layout. That is to say, an animation isn't going to change a view's measured height over time, it will just change the way it appears on screen over the duration of the animation. The mere presence of View1 in your layout will cause the layout to set aside its measured dimensions. I could be wrong, but I don't think an animation with a layout like this is going to achieve the effect you're looking for. You may have to do something where you change the measured height of the view over time and invalidate the view/layout at every tick to get it to re- render everything.

[android-developers] Re: Which JSON Parser is better
The JSON library built into Android (org.json) should be more than efficient for your needs on a mobile device. If there are inefficiencies in it, they almost certainly won't be large enough to cause a visible slowdown in your app unless you are transmitting a drastic amount of information over JSON - which isn't really what it's for.* *In addition, by using the built in library you can be assured that there will be fewer bugs than in something you write yourself simply because the included library is older and more widely deployed. Lastly, you save yourself the time, however minimal, of re-inventing the wheel. Before you write your own JSON parser, I'd just write your app with the included code. Later on, if you notice performance problems you can then measure and eliminate them no matter where they originate.

I really think what you're trying to do is most easily expressed as a LinearLayout (itself using width and height to fill parent) using the layout_weight property to make the middle view grab any extra space.

When I toast the value of lv_arr[i] it is null.
If this is your actual code, you need to initialize the array.
String[] lv_arr = new String[11];
Second, array indexing is zero-based, so you would start your loop from 0
and go to 9 (where i 10).
If I do this:
String[] lv_arr = {hello, hello, hello} + the for loop, I can get the
hello value when I do the toast. but [3]-[10] is still null value.
You've initialized an array to exactly three elements. Anything after that
(index 3 and above) is non-existent.
These are really basic Java concepts. If you don't understand this, I highly
recommend you go study Java on it's own and figure this stuff out before
trying to do an Android project. You're going to run into a lot of headaches
if you try to learn both at the same time.
