Android :: How To Write App To Connect Device To Host USB GPS Device

Oct 29, 2010

I have a standalone GPS enabled data recorder in my car that can function as either a USB host or device. (Its a class 0x00h USB device). I currently connect to it via a WM 6.5 app running on my Palm Treo 750. I would like to port my WM 6.5 app to an Android phone. (I don't have a specific Android phone in mind, I would like it to be as generic as possible).Replicating the GUI is not that difficult, but I am having trouble getting started on the USB communication. I'd appreciate it if someone could point me towards an example, or the appropriate tutorial.

Android :: Host Network When Debugging On Device Via Eclipse / ADB?

Jul 7, 2010

I have a Android phone connected with host computer with USB cable. ADB runs well and I can debug application on phone. The only problem is that the App requires special network setup which I can reach on host but not mobile. Is there a way to let the device send all network operations through ADB and Host network?

General :: IPv6 Access From Host To Android Device?

Jan 1, 2012

I'm trying to connect from a host (PC or other) to a mobile cellular Android device on the Verizon/AT&T cellular network. This device uses only the 3G network and has its Wi-Fi turned off. The Android device has a listening socket and I need the remote host to be the connection initiator. As far as I know, Verizon/AT&T uses NAT traversal for mobile phones and assigns local IP addresses to them on the cellular network. This prevents me from initiating a connection to the device from a remote host.

With the usage of IPv6 assignments there shouldn't be any practical limitation (virtually unlimited) to the number of "real" IPs that can be assigned.Therefore my questions are:

1. Does the Verizon/AT&T cellular network support IPv6 and assigns IPv6 addresses to capable Android devices?

2. Does Android 2.2+ have enough support for IPv6 to implement such solution?

I am aware of other methods that can be used, such as C2DM, but it has some drawbacks (such as unknown response time) that prevent me from using it.

General :: Android Device Cannot Write Anything Into Flash

Sep 9, 2013

I have a cell phone which name is Huawei Ascend P1. Now I have a problem, that is the devices can not bootup into Android's home and I can not write anything into flash, even using fastboot.

When booting, the screen stays on the welcome logo, and stay there forever, and adb could connect to linux shell on the phone. I can see all file on the phone, and I can save files after "mount -o remount / /", but after reboot, the file is gone.

If I use fastboot to flash a recovery into my phone, by follow command:

fastboot flash recovery recovery.img

The command line prompt says OK, but when it reboots, it still reboot into the previous recovery.

Android :: How To Create/write File In The Root Of The Device

Jan 17, 2010

I found out that you can use something like this to create a file:

CODE:............

When running the above code I get an IllegalArgumentException stating:

CODE:......

And Im guessing the "/" is not appreciated. I wanted the "/" since I need to write the file to the root directory of the device, as stated in the API in trying to follow:


CODE:.........

Question is: how do I place a file in the root-directory? I have been looking around for an answer, but havent found one yet.

Android :: Can't Connect To SPP Device

Mar 18, 2010

I currently run android 1.5 on a HTC magic. I'm trying to communicate from my phone to a bluetooth device that supports SPP. I can't seem to be able to connect to the device. I have tryed two ways to connect: 1- via the official 2.0 API using the backport-android to make it work on android 1.5 2- via the unofficial bluetooth api 0.3 Both method give me an error around the same connection process. ith API 2.0, I can discover devices and pair with them. Then i create a socket which seems to work, but when I use the .connect() method, I get this error in CatLog: IOException Unable to start Service Discovery. This is related to doSdp() in public class BluetoothSocket.Searching the web, it seems this error is related to a wrong UUID ... but I am using the SPP UUID properly. So, I thought the problem could be backport android, so I tried with the unofficial API from Gerdavax ( http://code.google.com/p/android-bluetooth/To connect to a device with this API you first create a socket, then you connect using the .openSocket( port number) method. The weird thing is, if I try with a new port, it connects, if I try a second time, it wont work, unless I change the port. I get a similar related error of SDP. Code...

General :: One-Tap Connect To Paired Device?

Oct 8, 2012

I am looking for an app/widget to add a tiny bit of convenience to my life. I want the ability to tap on an icon on my homescreen that will trigger a (Bluetooth) connect to a device that I have paired with in the past. A one-tap-and-you're-done widget would be perfect. I have a Bluetooth dongle in my car that I connect to quite often that plays music over a stereo system (HTC Stereoclip A100). The device is paired with my phone, but I must go to Bluetooth Settings and click on the device to connect every time I get into my car.

I have tried a few apps in the Marketplace with no luck. I am using ICS (HTC EVO 4G LTE). One specific app that worked, but no longer works in ICS: Bluetooth Profile Widget [URL]

General :: Automatically Connect To VPN On Device Startup

Feb 1, 2014

I have an android device: it's a stick connected to my TV, running android 4.1 rooted. The stick is an MK808B. The stick is connected to my TV's USB so that when I turn the TV on, the stick boots and when I turn the TV off, it shuts down completely.

I am looking for something that automatically connect the stick to VPN when I boot it. I would preferably use VPN over L2DP, although I'll take PPTP if there's no other option. I can't use openVPN because my ROM's kernel doesn't have TUN. There are two ways to approach this: one way is to connect it on boot, another way is to connect to VPN when the stick connects to a wireless network because my stick is stationary and always connects to the same wi-fi network.
