It handles whole image overlays so if you can create a single image that contains all your data then it works well. The v2 API has tile overlays which may work better for your application.

[android-developers] Re: switch between GPS and Networkprovider
Hi!
If you want to monitor the availability of GPS signals you have to
have a Listener constantly on the GPS_PROVIDER for status changes and
set and remove a different NETWORK_PROVIDER listener on those changes,
otherwise you won't get notified if gps signal is available again.
However you have to solve data passing and synchronization between the
two LocationListeners somehow.
If you need further help you can contact me in private.
Zod.

Hi,
I wanted to know how to switch beteen GPS and Network providers.
Iam now busy with making a program that shows the location of the
phone holder on the google map. I want to make use of both the GPS
provider and the network provider. I prefer using gps. When gps is not
temporarily unavailable then the program chooses for the network
provider. But when the gps is available again I want the program to
use the gps again.
At this moment my program is only able to switch to network provider
when gps is not available but it cant check whether gps is back again.
here is how it is done:
@Override
public void onStatusChanged(String provider, int status,
Bundle b) {
if (status == LocationProvider.OUT_OF_SERVICE) {
lm.requestLocationUpdates
(LocationManager.NETWORK_PROVIDER,
mInterval, 0, this);
}
else if(status ==
LocationProvider.TEMPORARILY_UNAVAILABLE){
lm.requestLocationUpdates
(LocationManager.NETWORK_PROVIDER,
mInterval, 0, this);
}
}
Could someone please tell me how to check the status of the gps while
the location manager is using the Network provider?
thank you

[android-developers] Installing USB drivers on Vista 64 bit
Hey all, I am currently having issues installing my G1 in development mode on Vista 64 Premium SP1. I have tried both installing the drivers that come with the latest SDK and also the ones here: http://forum.xda-developers.com/showthread.php?t=446274. Whenever I plug the phone in it comes up as an unknown USB device under device manger. When I go to update driver and point the installer at the correct driver location it either says 'the device driver is up to date' or when using the have disk option it says 'the folder specified does not contain a compatible software driver for your device'. Any help would be really appreciated - I have been hitting Google for about 2 hours now!

[android-developers] Re: onSaveInstanceState() normally not called ?
onSavedInstanceState() First make sure you don't have a typo, because it is called onSaveInstanceState(...). A case where it is definitely called is when you switch orientation (in the G1, slide out the keyboard). Then onSaveInstanceState(..) is called 100%, and onCreate(...) in the newly created activity contains the bundle that you stored yourself. (provided you let the system handle the screen orientation change). Does this work? It should. If you call finish() or press Back, then onSaveInstanceState() is NOT called, because it is assumed the user finishes the activity. If the user opens the activity again, a fresh instance is created. If you think the current directory should be the same after you press finish() and launch the application again, then it is NOT a candidate for saving in the instance state. If you only want to keep the current directory when changing screen orientation, or being interrupted by an incoming call, then saveInstanceState IS the correct thing for you.

[android-developers] Re: onSaveInstanceState() normally not called ?
Also onSaveInstanceState() will definitely be called when your activity is in the foreground and you press home. In that case the activity is not being finished, so the user may return to the same instance later (in the same state as they left it), so onSaveInstanceState() will be called before onPause() in case its process gets kill any time after onPause() returns.

If you are just writing a self-contained application -- it is all running in the same process -- then you really don't need to do anything special. Just normal Java stuff -- define a callback interface that the second activity implements, and hands to your network thread for it to call back on when it is done.

[android-developers] Re: targeting broadcasts issue
Dianne, I really don't want control over the notification at all. I beleive that i am either missing something or doing something the wrong way. maybe you can tell me what i am doing wrong or know someone that could point me in the wright direction. My understanding of intents is that the whole point of them is so that you can have multiple applications providing similar or the same functionality and that those applications become interchangable via intents. Now when a new sms comes in there is a notification in the notification bar and that notification will allow any application implementing the correct intent (action view and data of sms) to be triggered from the notification to display the sms. This part works perfectly. The issues is that when the notification trigers my application instead of the default messaging application the notification never goes away. I have marked the sms as read and done everything i can think of to try to trigger it to update the notification to either the next sms or to remove the notification. I am happy to post my code if that helps as i have to be missing something. It makes no sense to allow developers to offer alternative applications via intents with the notifications and then have the notification never go away. I mean i have clicked th notification to trigger the intent and i have marked the sms as read when my app loads the intent. Is there something else i need to do? Fire some other intent or something? This is all just an atempt to work around the issue http://code.google.com/p/android/issues/detail?id=2261. All i want to do is allow my users to send sms over the internet. The issues is why you can implement an intent for a new sms half the sms my users send are replies and since reply is built into most sms apps unless the issue above is implemented you need to write an app to view sms so that you can capture the replies hence what i am trying to do above. I really want to keep this as simple as possible as this is only a small part of my application but it is turning out to be the bigest time consumer.

Yeah currently notifications are very much owned by the app that created them, and there is no facility for other apps to interact with them.

better/correct way to completely clear resources used by an

[android-developers] Re: Intercepting bluetooth device buttons
Register your intent receiver at a higher priority, and call abortBroadcast() while handling the Intent.

However, I have the following problem: I have an application that plays audio and I listen through my bluetooth headset. When I push the play/pause button on the headset, my application get the corresponding broadcast and pauses the audio. However, the built-in Android music player also gets this broadcast and starts playing one of its audio files. How can I prevent this?

AVRCP events are broadcast as media intent's if the foreground application does not consume them. For example, KEYCODE_MEDIA_PLAY_PAUSE KEYCODE_MEDIA_STOP etc. HFP events are consumed by the Handsfree services, and as Mark says there's no easy way to hook into those.

[android-developers] How do I access a URI such as content://drm/audio/2 (which is a ringtone)
Hi all, I am trying to play a ringtone that is specified as the Default system ringtone. Unfortunately when i get the actual URI I get the above (content://drm/audio/2) and then when I try to play it, I hear the fallback ringtone - the one that you'd hear if the default was unavailable. Ringtones appear to get this URI when downloaded through sites such as Myxer and the like. Now it seems that when the default ringtone is on the SD card under a folder called 'ringtones' I do not run into this problem. I have tried to add the line: uses-permission android:name=android.permission.ACCESS_DRM / ...to the manifest but that doesn't seem to work either. If anyone has an idea as how I would be able to play this ringtone, I would be eternally grateful! I have been researching this and I can't seem to find anywhere any documentation on how to do this.

Hi Marco,Basically supplying the ringtone's URI to the RingtoneManager's getRingtone function (returning a Ringtone) and then calling play() to what's returned. Should i be doing it differently?
