[android-developers] iPhone-style 3-button remote control headset support
Is there any way to enable support for iPhone-style 3-button remote control headsets on Android devices? These are the ones that have a button for play/mute, and a pair of volume control buttons. Out-of- the box, this doesn't seem to work, but I wonder if there's a way for applications to obtain low-level enough information from the microphone line or if it's possible to write some sort of driver to do it. -- You received this message because you are subscribed to the Google Groups Android Developers group.

[android-developers] Can Bitmap native resources be recycled by Garbage Collector?
Hi, folks For Java objects, GC can free those objects that are not used any more. For native resources, such as Bitmap image data (not Java Bitmap objects), which are allocated using native code (C/C++, etc), can they be recycled as well? Or I MUST call Bitmap.recycle() to free the resource? Thanks! Gerald -- You received this message because you are subscribed to the Google Groups Android Developers group.

In light of the Nexus One availability in Canada starting today and as a Canadian developer, one thing I'm interested in is if the Nexus One we will receive is the T-Mobile or the Rogers version. I sent an e- mail to the android seeding e-mail address about this, keeping my fingers crossed it is the Rogers one but at the end of the day it is a free phone and no complaints if it ends up being the T-Mobile/AWS variant. -- You received this message because you are subscribed to the Google Groups Android Developers group.

[android-developers] Re: NumberFormat and comma as decimal separator
Thanks for the comments, I check with my user in Germany and he confirmed that he cannot type the comma into a decimal field in Android. The issue is arising for me because when I copy the text into the edit field I convert it into a localized String which has the comma in it. Once this gets into the edit field it makes my current usage of Double.valueOf fail for the reasons discussed above. I'll probably just change my code to enforce using the period everywhere for consistency until this issue gets fixed in a later version of Android.

[android-developers] NumberFormat and comma as decimal separator
I have a program that allows users to enter decimal numbers. One user
noted that my program requires that he use a period as the decimal
separator even though in his country (Germany) they use the comma
instead. No problem, I looked at my code and realized I was
constructing a DecimalFormat directly instead of using
NumberFormat.getInstance() and changed my code as follows:
formatter = NumberFormat.getNumberInstance();
if (formatter instanceof DecimalFormat) {
DecimalFormat format = (DecimalFormat)formatter;
format.applyPattern(PATTERN);
}
I then was going to test it in the emulator and changed my locale to
German. While the language changed there was no change to the number
format and it still used the period as the decimal separator.
Iterating over NumberFormat.getAvailableLocales() I can see that only
English and Japan based countries are returned in the emulator and all
those countries use the period not the comma.
Any ideas on how can I test my changes to make sure they work? I can
override the decimal separator which works fine for testing the
display of numbers, unfortunately the keyboard won't allow me to enter
a comma in a numeric field to test the parsing. My personal Android
phone only supports English and French. I tried changing it to French
but still get the period as the separator, feeling kind of stumped
here.

Hello. I'm trying to develop an app which mimic the MicrosoftPaint application. My current setup is that I have a single activity which contains multiple custom-view. These views correlate to the different tool that program can do. Example: 'pencilView' to simulate the pencilStrokes, 'rectangleView' to simulate the rectangle drawing, etc. Based on onOptionsItemSelected, I setContentView to the selected view, and then requestFocus. But I'm not sure of how to show the different strokes made to be on-top of each other. I tried to pass the canvas object around and call save (at the end) and restore (in the beginning) but that didn't work.

When I tried to run my build, an exception occurred, and I can't
find
where it actually from because it seems to be from an internal
thread.
After an whole day trying, I found that the exception is thrown by
the
line in Launcher.java possibly:
setContentView(R.layout.launcher);
Does anyone have any suggestion?
Thank you very much.
Gerald

[android-developers] Failed to execute the Launcher built by myself
Hi, I need to customize the launcher application. I built it from the android source, and installed it to the emulator successfully(By renaming its package name to solve signing conflicts). When I tried to run my build, an exception occurred, and I can't find where it actually from because it seems to be from an internal thread. After an whole day trying, I found that the exception is thrown by the line in Launcher.java possibly: setContentView(R.layout.launcher); Does anyone have any suggestion? Thank you very much.

[android-developers] How to re-install sign android built-in applications
Hi, I want to customize some built-in applications on android, for example Launcher or Contacts, etc. I've downloaded the source code and compile it by eclipse successfully. But when I tried to run it, a signing error comes: [2009-01-20 16:17:27 - Launcher] Installing Launcher.apk... [2009-01-20 16:17:35 - Launcher] Application already exists. Attempting to re-install instead... [2009-01-20 16:17:43 - Launcher] Re-installation failed due to different application signatures. [2009-01-20 16:17:43 - Launcher] You must perform a full uninstall of the application. WARNING: This will remove the application data! [2009-01-20 16:17:43 - Launcher] Please execute 'adb uninstall com.android.launcher' in a shell. I followed above instruction: adb uninstall com.android.launcher, but it failed (Can't remove the application). The official document only provides How to sign a new application, but it's not usable in my case. Does anyone know how to do it?
