[android-developers] Re: Self-restarting service

I suppose you could try having a parent service that only has the job
of keeping your other service alive. Essentially it could be crash
proof if you made it simple enough. I'm not sure but I think services
and activities can execute code when they're paused or closed.
Hopefully when something crashes onDestroy() still gets called. You
could write your main service to send an intent to the parent service
to get restarted.

Take all this with a grain of salt. My advice is just a shot in the
dark.

[android-developers] Self-restarting service

Hello,

I am developing a slightly "mission critical" Android application, and want a Service component of it to be essentially "immortal" or at least "self-restarting" in the event of a crash (of the service). What would be the best way to accomplish this? I use API level 3 (Android 1.5).

Thanks in advance,

[android-developers] Re: Sleep mode

Anyone? If it can't be done in any other way, is there by any chance any way to emulate that the 'end call' button has been pressed? (I've tried with dispatchKeyEvent() to my own activity, but that didn't do anything.)

Thanks,
Anders Feder

2009/10/24 Anders Feder <anders.feder.83@gmail.com>

Hello,

Is it possible to programmaticly send the device into sleep mode (i.e. like when pressing the [end call] button once so screen the turns off and locks)?

Thanks in advance,

[android-developers] Android SDK and AVD Manager

I just setup my development environment on a Windows XP VM and I'm
having problems getting the Android SDK & AVD Manager to retreive the
available packages. The message under Sites, Packages, and Archives
says "Failed to fetch URL". When I attempt to retrieve the 'Available
Packages', I get the following message:

XML verification failed for http://dl-ssl.google.com/android/repository/repository.xml.
Error: The markup declarations contained or pointed to by the document
type declaration must be well-formed.
Failed to fetch URL http://dl-ssl.google.com/android/repository/repository.xml,
reason: Unknown
Failed to parse XML document

I have the Windows firewall turned off, no antivirus software, and
have the "force https:// ...to be fetched using http://" checked. I've
also tried manually creating a file named 'androidtool.cfg' with the
text "sdkman.force.http=true".

Still getting the same error. Any ideas what to try next?

Ever Attended A Mustache Wedding Party?

Ever Attended A Mustache Wedding Party?

Loading images, Please wait...

Brides and their grooms and their guests love fake mustaches. LOVE THEM. I have no idea where this trend came from, but within the last month I've seen enough mustachioed wedding parties to realize that this isn't an isolated incident. And in fact, it's not even just weddings — mustaches are everywhere.

I'm telling you, fake mustaches are hot right now, people. Fake mustaches are the new red wedding dress. Take a look at all the mustaches in the funlobby bride flickr pool!

I get that it's a trend … but can anyone tell me why? Where did it come from?

[android-developers] Locale and TTS problem

I have set my emulator to use US English.

When I run Locale.getDefault()

There is no country code!
The language code is set to "en_us"

When I set a varaible "audioLocale" using

audioLocale= Locale.US

The country code is "US"
The language code is "en"

When I run

mTts.isLanguageAvailable(audioLocale) == TextToSpeech.LANG_AVAILABLE

I get

-2 == 0

Why is mTts reporting that the US language is not available?

[android-developers] Re: AppWidgetProvider

Ah right, yes I believe there is an emulator only bug in 2.0 with
widgets. I've experienced your problem before, launching a new
emulator usually fixes it. Haven't really been able to track down the
cause of it but I don't think it will be a problem with devices. I'm
not sure if it has any effect but lately I've been running a lot of
different emulators at once, which could cause problems, sometimes I
have emulators launch with crippled performance and small things like
that.

When I experienced this problem, the solution for me to was to do a

[android-developers] http client connect timeout

I try to set timeout for apache http client like this
HttpConnectionParams.setConnectionTimeout( params, TIMEOUT );
But it does not work
Is there a way to set connect timeout for http client on Android?
Thanks

[android-developers] Re: Debug question

One additional data point. The line:

[2009-10-31 17:13:10 - MyApp]Application already deployed. No need to
reinstall.

appears at the beginning of a launch. The application is *not* seen
under Manage Applications on the device nor does it appear anywhere as
a background [hidden] task.

[android-developers] Debug question

After much screwing around with configuration settings I finally got
Eclipse to recognize and attach to a tethered MyTouch for debugging.

The problem now is that before running the debugger I have to manually
push the build to the device in order for the debugger to launch it.
If I do not first manually install the file on the device it does not
get uploaded and I see the following errors in the android console
window:

[2009-10-31 16:54:05 - MyApp]Starting activity com.me.android.MyApp on
device
[2009-10-31 16:54:06 - MyApp]New package not yet registered with the
system. Waiting 3 seconds before next attempt.
[2009-10-31 16:54:09 - MyApp]Starting activity com.me.android.MyApp on
device
[2009-10-31 16:54:11 - MyApp]New package not yet registered with the
system. Waiting 3 seconds before next attempt.
[2009-10-31 16:54:14 - MyApp]Starting activity com.me.android.MyApp on
device
[2009-10-31 16:54:15 - MyApp]ActivityManager: Starting: Intent
{ cmp=com.me.android/.MyApp}
[2009-10-31 16:54:15 - MyApp]ActivityManager: Error type 3
[2009-10-31 16:54:15 - MyApp]ActivityManager: Error: Activity class
{com.me.android/com.me.android.MyApp} does not exist.

If the file exists then the debugger attaches and breakpoints work but
the old image is the one that is always connected to as automatic
uploads still do not happen upon rebuild/redeploy.

I have tried turning USB storage on and off but that does not work
either.

Am I missing an address setting or checkbox somewhere?

Found it on http://developer.android.com/guide/topics/resources/available-resources.html:

<quote>If you use an apostrophe or a quote in your string, you must
either escape it or enclose the whole string in the other kind of
enclosing quotes</quote>

Does not give a reason though.

I think it's documented somewhere. I remember it from my one book, and I

[android-developers] Back key after Search doesn't return to list in 2.0 as it did in all earlier versions

Hi all,

I experience something slightly confusing in the 2.0 emulators (tried
several variants):

One of my apps is somewhat similar to Market in structure in that it is
a ListActivity that keeps creating new Intent(this, xxx.class); of
itself with various .putExtra(); that presents data in appropriate ways.
In the Manifest there is also an intent-filter for action.SEARCH that
triggers onSearchRequested() and then onCreate() checks for
Intent.ACTION_SEARCH - pretty straight forward IMHO and it has also
worked exactly as intended up to and including 1.6 (where the new search
stuff seemed to integrate as expected).

However, in 2.0 I don't get back to the previous ListActivity when I
have used the search key to show something and then press the Back key.
The back key takes yet another step back.

Is this related to some other Back key issues I've seen mentioned here,
an intended new behaviour that I must handle differently in 2.0 or some
kind of bug that needs reporting. I don't have any kind if special key
listening going on at all.

Best / Jonas

PS. Lack of account handling and hardware to test Bluetooth on really
makes the emulation testing a pain - I'd love a Moto Droid over here.
Any suggestions as to how I can get my hands on one soon would be much
appreciated...

[android-developers] Re: second dialog in activity is not showing

The UI is not thread safe and calling related methods from a
background thread like that run by java.util.Timer can cause trouble.
There's a good blog post on ways to schedule work on the UI thread or
communicate back to it here:
http://android-developers.blogspot.com/2009/05/painless-threading.html

There's also an example of communicating back to the UI thread called
"Example ProgressDialog with a second thread" on this page:

[android-developers] Double quotes in resources?

I'm probably missing something obvious, but for some reason I don't
manage to put a string with double quotes in a resources file.

strings.xml:
<resources>
<string name="message_empty_folder">Folder "%s" is
empty.</string>
</resources>

LIstFolderActivity.java:
String format = getResources().getString
(R.string.message_empty_folder);
System.out.println(format);

Log output:
Folder %s is empty.

What's eating up the double quotes?

Thanks in advance,
Markus

[android-developers] second dialog in activity is not showing

Hi android guys and girls!

I have a really strange problem. I have an activity which displays a map
and a marker with the users current location on that maps.

Right now my code is something like this: (in onCreate of the activity)

1) display a progress dialog with the text "detecting your location,
please wait..."

2) request location updates. (activity implements LocationListener)
locationManager.requestLocationUpdates(provider,
(long)Constants.MIN_TIME, (float)Constants.MIN_DISTANCE, this);

3) right after the line above i have following:
timer.schedule(new GetLastLocation(this), 5000);
which means: wait 5 sec and then call GetLastLocation().run()

GetLastLocation looks like this:

class GetLastLocation extends TimerTask {
private SetupActivity parent;
public GetLastLocation(SetupActivity act) {
parent = act;
}
public void run() {
removeDialog(DIALOG_GET_POSITION);
parent.showMessage();
}
}

So if 5 seconds pass by, i dismiss(remove) the dialog i displayed in 1)

4) now i want to show an AlertDialog with the message "could not find
your location, taking the last known"
parent.showMessage() looks like this:
public void showMessage() {
Log.e("###", "showMessage 1/2");
showDialog(DIALOG_GET_POSITION);
Log.e("###", "showMessage 2/2");
}

and here the first log message "showMessage 1/2" is printed to the log,
but not the second one "showMessage 2/2".
And there is no exception and nothing that tells me what is wrong...

Could someone please help me?
Maybe there is a better way to get he location and if no location is
delivered show a message!

Thankful for every hint,
Anton

[android-developers] Re: AppWidgetProvider

Yea our provider is fully public. Our widgets worked perfectly fine,
well we worked around the current widget bugs, until 2.0. The 1.6
release we have no problems on actual phones or the emulator with the
2.0 emulator is where we see the problems, hopefully it's just a bug
in the emulator. But it would be nice to know either way.

[android-developers] Mystery Null Pointer Error - Seeking Opinions

*,

An error that appeared in my Flurry logs but seemed impossible to reproduce otherwise just occured! That's the good news. The bad news is that the LogCat info is not telling me enough. I would appreciate a second set of eyes taking a look and offering wisdom.

The lead up is that I was playing with my app, and put it away for a while. I did a lot of other things with my phone since, like making phone calls, etc ... I hooked up my phone to the computer to make another attempt to find the mystery bug, and decided to see if anything weird appeared in the logs from earlier. I then brought my app to the foreground using the Home/Hold technique and whamo! the bug appeared before my eyes in LogCat.

I got a Force Close message. When the app died, it did not get resurrected. What is particularly odd is the "onPrepareOptionsMenu" being called (at all).

So here is what LogCat coughed up:

This is not my app but may provide a clue ...

[android-developers] Re: IMPORTANT - display.getOrientation() does not work on all devices

Well then this is extremely confusing!

Firstly, thanks Mark for taking the time to test it.

The only other thing which could be wrong is how the coordinate system
is represented in each device. I draw to the screen once I have
remapped the coordinate system i.e.:

if(screenOrientation == 1) { // Portrait
SensorManager.remapCoordinateSystem(R, SensorManager.AXIS_MINUS_Z,
SensorManager.AXIS_X, outR);
}
else { // All other send to Landscape
SensorManager.remapCoordinateSystem(R, SensorManager.AXIS_X,
SensorManager.AXIS_Z, outR);
}

However, this shouldn't be an issue should it?

I just tested this on a G1, and
getResources().getConfiguration().orientation is 2 in landscape and 1 in
portrait, just like it should be.

I also tested it on an HTC Magic, and it works just fine.

Heck, it even works on an ARCHOS 5 Android tablet.
