Bluetooth Devices - Array List Isn't Populating
Dec 8, 2013
I'm writing a small program in which I'm using my phone to detect Bluetooth devices. I'm currently stuck on populating an array list with the names of all the device names that have Bluetooth.
Code:
Set<BluetoothDevice> pairedDevices = mBluetoothAdapter.getBondedDevices();
if (pairedDevices.size() > 0) {
for (BluetoothDevice device : pairedDevices)
mArrayAdapter.add(device.getName());
[Code] ...........
For some reason, the array list isn't populating. Also, how can I display the array list in a ListView

I've spent hours trying to figure this one out with no luck. I have an LG Ally and Jabra BT350 earpiece. How do I remove Bluetooth devices from my list? I've tried everything. I can add as many as I want, but I can't figure out how to remove them!!

Since Bluetooth is sketchy on the Hero, I figure it would be useful to have a list of peoples' experiences with different devices. If you have a Bluetooth device, please reply with it's manufacturer, name, the exact OS you are using, and how well it works. I'll try to keep this post updated.
Stock 2.1:
* Blueant Interphone (motorcycle helmet bluetooth) -- Works
* Jawbone Icon -- Works for both voice and A2DP
* Parrot CK3100 car kit -- Works for voice and enables voice dial
* Plantronics Voyager Pro -- Works
* 2010 Mazda 3 GT with Bose stereo system -- Works for voice but not A2DP
* Blue Ant T1 -- Does not work properly
Stock 1.5:
* Blueparrott B250-XT -- Works
* Foxl G-2 Bluetooth speaker -- Works
Fresh 2.3.3:
* Blue Ant T1 -- Does not work properly

I am using a progress bar in android, so that till my data is loaded, user is getting a proper feedback of what is going on.
The code for the bar is below:
CODE:............
The setSelected() method is inserting data into an array list, and then creating an array adapter and then using a list view to show those items. so when I put the setSelected() method in progress bar, it shows the loading circle, but once loading is done. Nothing is displayed in listview. But if I take out progress bar code (thread and run method), and simply call setSelected() method, the listview successfully declares the data. so far it concludes that the progress bar code is doing some thing...so wanted to know am I missing something to add in or take out from the code. I need to the show progress bar as I am reading data from online source and it takes time , which may make user uncomfortable.

I am using a simple expandable list that is populated by two arrays ( group array for the groups and a multi dimensional children array for the child). The arrays are built dynamically in the program and some group items have more children than others. So I end up defining the highest number as the array size for the multidimensional child array. After populating the child array, some positions are left null, as there are no values for those group items (explained above). When I associate this with the expandable list adapter, the getChildView method throws a nullpointer exception when it comes across a position in child array that does noto have value. I have two questions:
1. Can I make the base adapter skip the shildview method if the value in that child is null? The current implementation of getchildView method has to return a view and even if I suppress the nullpointer exception, it adds a blank element in the child position in the list.
2. Is there a better way of associated multidimensional arrays that are populated at run time? The current set of examples only use hardcoded string array values. Even the cursor adapters examples use very basic setup.

After several hours of searching for the cause of a Out Of Memory Error, I found a wierd problem with Strings. To keep it simple, trimmed it down to something like this:
ArrayList<String> someStringList = new ArrayList<String>(1000);
for (int i=0; i<1000; i++) {
String someBigString = new String(new char[100000]);
String someSmallString = someBigString.substring(0,1);
someStringList.add(someSmallString);
}

I have an array adapted listview (the array adapting is done in another class). I just got the click listener working for the list but now I want set it up so that when I click an item. It pulls the strings from the clicked item and piggybacks them on the intent to a new activity. I figure I am supposed to use intent.putextra however I am not sure how to pull the correct strings corresponding to the item that i click on. My code is below. I am simply lost to be honest
//Initialize the ListView lstTest = (ListView)findViewById(R.id.lstText);
//Initialize the ArrayList alrts = new ArrayList<Alerts>();
//Initialize the array adapter notice with the listitems.xml layout
arrayAdapter = new AlertsAdapter(this, R.layout.listitems,alrts);
//Set the above adapter as the adapter for the list
lstTest.setAdapter(arrayAdapter);
//Set the click listener for the list
lstTest.setOnItemClickListener(new AdapterView.OnItemClickListener() {
public void onItemClick(AdapterView adapterView, View view, int item, long arg3) {
Intent intent = new Intent( HomePageActivity.this, PromotionActivity.class );
finish(); startActivity(intent); } } );
my alerts class..
public class Alerts {
public String cityid;
public String promoterid;
public String promoshortcontent;
public String promocontent;
public String promotitle;
public String locationid;
public String cover;
@Override public String toString() {
return "City: " +cityid+ " Promoter: " +promoterid+ "Short Promotion: " +promoshortcontent+ "Promotion: " +promocontent+ "Title: " +promotitle+ "Location: " +locationid+ "Cover: " +cover+ "$"; } }
anddddd my alertsadapter class..
public class AlertsAdapter extends ArrayAdapter<Alerts> {
int resource;
String response; Context context;
//Initialize adapter public AlertsAdapter(Context context, int resource, List<Alerts> items) {
super(context, resource, items); this.resource=resource;
} @Override public View getView(int position, View convertView, ViewGroup parent)
{ LinearLayout alertView; //Get the current alert object Alerts al = getItem(position);
//Inflate the view if(convertView==null) {
alertView = new LinearLayout(getContext());
String inflater = Context.LAYOUT_INFLATER_SERVICE; LayoutInflater vi;
vi = (LayoutInflater)getContext().getSystemService(inflater);
vi.inflate(resource, alertView, true); } else {
alertView = (LinearLayout) convertView; }
//Get the text boxes from the listitem.xml file
TextView textPromo =(TextView)alertView.findViewById(R.id.txtPromo);
TextView textPromoter =(TextView)alertView.findViewById(R.id.txtPromoter);
TextView textLocation =(TextView)alertView.findViewById(R.id.txtLocation);
//Assign the appropriate data from our alert object above
textPromo.setText(al.promocontent); textPromoter.setText(al.promoterid);
textLocation.setText(al.locationid); return alertView;
} }

I'm trying to connect to connect to my T-Mobile G1 to test a simple android app I an creating. I cannot get it to show up in the list of connected android devices. Here are the details: - 32-bit Windows XP - I have enabled USB Debugging on my device - I am not prompted with the New Hardware Wizard when I plug my device in, it is merely seen as a new removable drive. It does not appear under any other categories in Device Manager, nor is there a new "Unknown Device" entry anywhere to be found - I have tried "Update Driver" and select the driver that Google provides for their official developer devices, but it says "this driver does not match your device" or something to that effect. Probably because it is expected a device type other than "Disk Drive" - I have tried uninstalling the device under "Disk Drives" and plugging it in again but it always gets reinstalled automatically as a "Disk Drive" - I have tried uninstalling the device, manually installing the Google driver from the INF file and plugging in the device and it is still only recognized as a "Disk Drive" - Most importantly, I get a blank device list when I run "adb devices" from the Android SDK tools directory before and after each step I tried After hours of scouring the web I get the distinct impression that a new device category should be popping up in Device Manager if the driver is installed correctly, but I have not been able to get the device to come up as anything other than a new "Disk Drive"

I bought a stereo bluetooth receiver from DealExtreme for $13 so I could use it in my car. It has a built in mic, so if calls come in, I can pick them up, but I drive a convertible, so it's too noisy in the car to use that.
I also have a jawbone bluetooth headset that I use in the car...it works great for phone calls in a noisy enviroment.
I just discovered that if I go to Settings:Wireless Controls:Bluetooth Settings and long press on the BCK-08 (the stereo bluetooth module), I can select options, and uncheck the 'phone audio'.
Now, I can use both at the same time...and the cool thing is that if a call comes in while listening to music, it mutes the music till I hang up, then starts it back up where it left off!

I know there isn't bluetooth API in 1.0 SDK, but I have a doubt. I need to know the visible bluetooth devices. That is, I only need do a scan of the bluetooth devices and save the diferent addresses. I don't need connect to them.
I have read here
http://groups.google.com/group/android-beginners/browse_thread/thread...
that API "only expose functionality to use/control headsets (audio profile)."
And now my question: It is possible do this functionality? Can I find which bluetooth devices are visible?

First - let me know if this is not the correct discussion group.
How do you remove a bluetooth device?
Path I'm taking:
- Settings
- Wireless & Networks
- Bluetooth Settings
- Menu
The only option I receive via menu is 'Scan for Devices'

I'm trying to setup bluetooth trusted devices on my Moto X so I don't have to unlock the phone when I'm near my computer, but for some reason, the bluetooth connection keeps disconnecting whenever the phone goes to sleep. I tried using my Jambox as a trusted device, and it worked fine.

I have brought over an unlocked G1 phone from the US that I'd like to activate without a SIM card. I've added the necessary entries in the android rules file /etc/udev/rules.d/ (I'm using Ubuntu Hardy). Now the G1 is recognized by the OS as an external USB drive, but 'adb devices' returns an empty list. Is there an instruction page somewhere for this?

I am trying to connect my Acer Liquid with ADB and DDMS under Ubuntu 10.04. I read some posts and already add the VID (0502) and PID(3202) in /etc/udev/rules.d/51-android.rules, but adb devices still list my phone's name as question mark. When I try DDMS, I got the following error: E/DDMS: device (????????????) request rejected: device not found. Is there something I missed?

Galaxy S f/w 2.1. It doesn't find either of my bluetooth devices - headset and handsfree. My old phone worked fine on both of them.
I enable Bluetooth. The icon goes nice and green. The blue squiggly thing appears in the top bar.
I activate my VisorBlade hands-free device. It beeps and the right lights come on. But no glimmer of recognition from the Galaxy. I go to Settings > Wireless and Network > Bluetooth > Scan Devices. Nothing found.
I switch on my Plantronics Voyager 520 and it beeps and the right lights come on. Phone remains nonchalently aloof. Scan for devices. Nothing doing.
But. My PC finds the phone when I do the Make Device Visible thing.

My gf's computer is going south, but all she really does is go online. If I were to find a way to connect her Evo to a monitor (this should be easy with and HDMI cable, right?), a mouse (bluetooth?), and a keyboard (can you do two bluetooth devices at the same time?), she'd be able to essentially have a computer when she docks her phone to all this, right?
But, does Andoid have an app and Evo the capability to bluetooth to a mouse and keyboard and is the HDMI cable the way to go to get the display on a spare monitor, or could I use the USB? Just thinking out loud here. Cell phone processors are fast enough to handle internet browsing and emailing, which is pretty much all she does, and the speed of the connection (we're in a 4G area) would make downloads fast. How could it be done?

I am trying to use Bluetooth SPP to communicate over it. In some Android phones, SPP profile is not activated. I faced the problem in the application that SPP was not activated and so the connection could not be established over bluetooth and when I started another app that is 3g hotspot which I think activates SPP and I was able to connect over bluetooth in my app.
So, how can we actually activate SPP profile of bluetooth in Android devices? And does all the android devices has SPP profile?
