Android :: Determining Unique Bluetooth MAC Address
Nov 15, 2010
Is it possible to determine the unique bluetooth MAC address for an iPhone and an Android (and to a lesser extent, other smartphones) from within an app on said device? Is my assumption that the MAC address is universally unique correct? A general yes or no would be helpful. Example code in the case of an iPhone or an Android would be extremely helpful.

I see another thread on Locale, but it seems to be focused on it technical shortcomings. I thought a thread about how people are using this app would be helpful.
Now... I use Locale for the following:
- Turning the ringer down when I get to work (obviouse one)
- Turning GPS/Bluetooth/wifi on when I plug it in the phone (think car dock)
- Turn on Wifi when I get near my known hot spots.
- Turn off GPS/Bluetooth/wifi off and turn down brightness when my battery is low.
And the last one is a good one for me...
- I have a GV number. When I call my phone from that number, it turns the ringer volume all the way up and it turns on wifi and GPS. This is my "lost phone aid". It turns on the locating features so I can see where the phone is using iGoogle and Latitude, and I can hear the phone if it is "in the cushions" on vibrate.
Anyone else get creative with Locale?

I've a snazzy bluetooth thang in my car. On my old phone (TyTN II) and work phone (Nokia somethingorother), when you pair the phone, it uploads the phonebook so that it's browseable from the car kit.On the Sammy, all I see is a list of phone numbers, no names. Which is less than useful.

How can I tell if a device is using HTC's SenseUI? I thought about using android.os.Build information, but they seem inconsistent. Is there a more definitive way? I need to be able to tell if I can launch the calendar by using com.android.calendar or com.htc.calendar.

My question is- with the telephony manager, is there a way to determine what number the phone is off hook with? I thought getLine1Number() might return that phone number that is being dialed, but it is not what I expect. I am working with 2 emulators, and added a log line so that I could see what that method is doing. When dialing another emulator, I expected getLine1Number() to return 5554, but it was 15555218135. Perhaps there is another method I should be using instead? Do I need to be into the source code to get the information I want?

I was wondering if there is a way to determine who passed an intent to my application. For example, I have a service, that I want to act differently depending on who passed the intent (for security reasons). I'm trying to sandbox each calling application, so they only have access to their data stored in my application.
For it to be secure, I cannot trust any application to be truthful about the identifying data it is passing into my service. Therefore, I need some system way of identifying who sent the intent in a way that the calling application cannot change that information. I don't know if it is possible, but I can't find anything in the Intent class, and I was wondering if there may be another structure which does what I want it to. If it is not possible, I would like to get some type of mechanism to do this in the roadmap.

I'm using a UNIX socket to facilitate communication on and Android device between a system level daemon I've got running in C and an application I've got running in Java. I'm much more of a C coder than a Java coder, so I'm having some issues when trying to read in data from the socket on the Java side. Currently, my code is as follows:
try{//Prepare to write the command and read the ACK
InputStream is = receiver.getInputStream();
OutputStream os = receiver.getOutputStream();
BufferedReader in = new BufferedReader(new InputStreamReader(is));..............................

How do you determine (programatically) if an Android device is: rooted Running a cracked copy of your software or rom. I have some sensitive information in my database, and I would like to encrypt it when the phone is rooted aka the user has access to the database. How do I detect that?

Question: How do you programmatically distinguish between directories and regular files in the assets folder?
When using AssetManager to access files in the assets folder, it seems impossible to determine if a file is in fact a file or a directory. You get the list of files from the list method and then open the file using the open method. I thought perhaps using the openFd method to get the asset file descriptor (and then subsequently requesting the normal file descriptor) would provide me some information. But requesting the file descriptor for a directory results in an IOException (which makes sense since what would it mean for a directory to have a file descriptor...?).
Currently I'm relying on that IOException (resulting from attemptng to open a directory in the assets folder) in order to determine if a file is in fact a directory. (Opening a regular file works just fine). This seems like a bad idea. Any other suggestions to distinguish between a file and a directory?

I am calling the ZXing scanner from Screen-A using intents. Once the scan is done control of course returns to the code behind Screen-A and I do some other work before calling Screen-B. Problem is the screen is black during this work period and I cannot determine the proper context to use to display a "working..." Toast/msgbox.

I'm working on an Android App where the user has different options for sorting the displayed data that comes from the database. Currently my orderBy string that I pass to Androids query() method looks like this:
"LOWER("+columnName+") ASC"
The problem with this is that if the data type in the column specified by columnName is integer, calling LOWER() on it will cause it to be sorted alphabetically, i.e. based only on the leftmost digit, which of course doesn't make any sense for numeric data. Hence I only want to apply LOWER() if the data type of the column is not integer. What I have in mind is a statement like this:
"CASE WHEN [data type of columnName is integer] THEN "+columnName+" ASC ELSE LOWER("+columName+") ASC END"
The part in the brackets is what I don't know how to do. Does SQLite provide a function to determine a column's data type?

I wish to have one application that runs in the background, which knows when any of the built-in applications (messaging, contacts, etc) is running. So my questions are: How I should run my application in the background. How my background application can know what the application currently running in the foreground is.

This seems to be a bit of a vexed issue: see
http://groups.google.com/group/android-developers/browse_thread/threa...
Like the person who started that thread, I need to get a unique ID for a device, without using scary permissions for TelephonyManager. I've tried
id = android.provider.Settings.Secure.getString(getContentResolver(), android.provider.Settings.Secure.ANDROID_ID);
but that just produces "android_id" on my phone. I'm using a Nexus One and Android 2.1.

Is there a unique ID that is given to Android handests that is available through the SDK?
I want to provide a web-service with actions that can only be performed once per resource per user. Maybe there is a different way to go about this. Any ideas?

I'm looking for a way to identify a phone by a unique string or number. That is, get a phone to give out a code which I can say is unique to that specific phone. The IMEI or IMSI would normally do (sim- specific rather than phone-specific is ok), but they require extra security privileges and I would like to avoid that. Is there any other way?
