I'm trying to get the ANDROID_ID on two different devices but it always return null on both. I'm using a Google Ion (aka HTC Magic) with firmware 1.6 and a Motorola Milestone with firmware 2.0.
I've been using this small sample to show the id, but it always shows null:

As the title says? Or what situations can cause this method to return null? I would of thought it retained this object always.

I came up with the idea, that its only possible to have that location null, after starting the device the very first time. But also than google will check the location right away for my opinion.
Sure, I'm implementing a default location for this rare case. I just want to know how seldom this case is.
I am doing some android application. I just wonder what will case the managedQuery method return a null value?

I'm building an android app and I'm currently having trouble retrieving a bitmap from an URL.
Here is the code I'm using :
CODE:..........
Everything works fine when the picture's write but when some bytes are wrong, result gets null. I think it's basically expectable as it's written this in the doc of BitmapFactory.decodeStream :
If the input stream is null, or cannot be used to decode a bitmap, the function returns null. The stream's position will be where ever it was after the encoded data was read.
The problem is, my wrong picture is well interpreted by my web browser and I can do so on iPhone platform.
Is there a way to sort of ignore those wrong pixels? maybe with the option parameter?

I can not see my device on adb devices. I also got a Sony Xperia and I can not see it on the list either. I upgraded the phone software (the HTC) to 1.6 a few days ago. Maybe that is what caused the change, but I could not be sure.

Is there an equivalent to Java's null layout in Android? Basically I want to specify the x and y coordinates of each component and not have the layout manager choose where they go. They will be within a scroll pane so it doesn't matter whether they fit on the screen.
I know null layouts are generally not a good idea but I have a special case where I need it. I'm porting a Java TV guide app and the program grid is made up of JLabels. The program dynamically generates them all, setting the x and y coords based on start/end time and channel. Each program could start and end at any time so as far as I know a table layout won't work.
I have a picture in the setImageResource, but I want to make it null; so far I am using i.setImageResource(1), but would like to know a better way.

I am having a real hard time with the geocoder API of android sdk 1.5rc2. In my app I am trying to get the addresses corresponding to a location name by using the getFromLocationName method of the Geocoder class. But the problem is whenever I call this method it returns a null value. I have also pushed a geodb file containing some fake addresses at 'data/misc/location' directory in the phone.
The format of the data in the geodb file is as follows :
address 1 latitude "38.898763" longitude "-77.036655" line 0 "1600 Pennsylvania Ave NW" line 1 "Washington, DC 20006" locality "Washington" region "DC" postalCode "20006" countryCode "US" countryName "United States"
and following is the code snippet : Geocoder geocoder = new Geocoder(this, Locale.getDefault()); List<Address> addresses=geocoder.getFromLocationName("1600 Pennsylvania", 10);

Following other threads - I'm trying to get a unique device ID from the device. I tried this:

why RingtoneManager.getRingtone(this, Settings.System.DEFAULT_RINGTONE_URI); always returns null when launching from my activity?
