Iam connecting 3G phone for my Android device for internet connection and another Socket(SPP) for CAN signal receiving.Whenever I manually connect to the Bluetooth tethering via 3G phone, i can browse internet perfectly and speed is good.Whenever programmatically connect to the 3G connection, i couldn't browse internet.i checked in shell and observing that in my mobile 'device is connected' message displayed and E symbol appears.No problem for me to connect Socket.But I got problem to use 3G phone.For this iam using APN/DUN mode.I checked both but no use.Is there any performance issue here or anything wrong to connect different devices by using Bluetooth API in android.Why this happends while connecting Mobile programmatically.
View 1 Replies View RelatedI was cleaning all the crap off my phone I don't use anymore and I believe I accidently removed the bluetooth software that allows it to connect to stereo bluetooth headsets. I can control the player with the headset, I can make phone calls from it, but when I try to play music there is no sound.
I was trying to reset the phone using RUU, but it reboots the phone and then says it cannot reconnect after that and the software shuts down. I can still sync with outlook, so my driver is not the issue. I am out of ideas.
Is there anyway possible to reinstall just the bluetooth portion of the rom?

View 3 Replies View RelatedI'm trying to write a basic camera app. The problem that I am facing is that it works fine in emulator but on the phone (Nexus one) it fails.
The point of failure is the very first call, i.e. Camera.open(). It fails on the phone saying "Failed to connect to camera service". Any idea what could be wrong? (BTW, I am calling this from my activity's onCreate funtion itself, could that be an issue?)
For the information, I do have the necessary Camera permissions specified in my manifest xml file.
I apologize in advance for this long post, but it's necessary to show what is happening.
I've been working on an app that works on the 1.6 emulator, but bombs on my G1.

All this works on a 1.6 emulator, but when I run this on the G1, LogCat shows:

And /data/anr/traces.txt shows:

It sounds like the problem is a timeout issue, but I am at a loss as to where I should be looking ....
I had my camera set to this.setRequestedOrientation(ActivityInfo.SCREEN_ORIENTATION_LANDSCAPE); and it works fine but if I change it to PORTRAIT instead of LANDSCAPE then it crashes with the following error...

It crashes at mCamera = Camera.open();
My Manifest file has <uses-permission android:name="android.permission.CAMERA"></uses-permission>
How do I fix this so I can view my app in Portrait?
At the moment i have the following problem. I try to establish a connect to a SOAP-service. Therefore i need basicauth via http. I use ksoap2 and HttpTransportBasicAuth. The problem is, I do not know how i can start a call when i use HttpTransportBasicAuth because the function "call" is not available.

View 1 Replies View RelatedI'm developing an automatic vulnerability scanner/exploiter for android. I'm adding the cool feature of using the metasploit framework from our android phones.
I can start the MsfRpcd ( the metasploit daemon ) from a su shell an make it bind to the 127.0.0.1 address.
I can connect to the server using busybox netcat ( no Java though here ).
I can't connect to 127.0.0.1 from the android app! i got ECONNREFUSED.
After a bit of google i understood that JavaVM have a separate network and it filter out my connection to localhost/127.0.0.1.
how can i connect to a service bind to 127.0.0.1 on my phone from an android app?
I gave a quick look at iptables -L output, maybe i can make some hack there, but probably i will break the JavaVM network.
Binding on wifi ip is not an answer.

View 3 Replies View RelatedI am looking for a way to initiate the audio connection between the Android phone and my headset within my application. The idea is to simplify the connection process in such a way that the user doesn't have to go through the different settings menus anymore (Apps -> Settings -> Wireless & Networs -> Bluetooth settings).
Both devices are supposed to be already paired and the Bluetooth address of the headset to be known.
As far as I learned, the Bluetooth capabilities (available since version 2.0 of the Android SDK) are restricted to Bluetooth discovery and the connection of RFComm channels (host/client) between the Android phone and a Bluetooth device. Is there another way to request Bluetooth profiles on the Android system to initiate a connection to a known device from an app or is this impossible?

I'm trying to register the phone as a HID device through bluetooth. So far I did the following - Created a BluetoothServerSocket with bluetoothAdapter.listenUsingRfcommWithServiceRecord("Any name", "00001124-0000-1000-8000-00805f9b34fb"). The UUID is the standard one for HID devices. - Paired the phone with a Windows PC - The phone is recognized as "Bluetooth HID device, but I get the error "Device driver software was not successfully installed"
Does anyone know what steps can be taken next to make it work? I think I should register a SDP service record, but I'm not sure if Android Bluetooth API has support for this.
On my phone, a dev phone, the bluetooth headset service is always running even though bluetooth connectivity is disable in the Settings app. Is this normal?
The ear speaker is not emitting any sound for maybe two weeks now, even if the on-call sound level is at max (5), so I'm checking a few things before I try to send back the phone for repair or exchange.

I am trying to write an Android app to connect to an existing web service. I'm pretty new to web services in general, other than what I've done with this first web services (written with JSPs, Struts 1.x, and JAVA). This web service is connected to a document storage database. The user would first login to the service, then using search parameters (document title, type, etc.) the user would be displayed a list of possibly relevant documents. The user would choose a specific document from that list, and the service would then stream the entire document (pdf file) to the user for viewing.What methods are available to Android where I can make a request given some specific parameters, and be able to parse a response?The only thing I know of is HTTP, but my project leader (I'm a summer intern) is hinting that there are others available. I'm not sure where to start looking.

All this does is catch an exception with the message "Null". Note that I am not an android developer, this is my very first project.
I did the same thing with Netbeans and regular Java and it works perfectly.
