Android :: USB Adb Connection Unknown Device Which Has No IDs
Oct 15, 2010
This month, I am not able to get a AT&T Samsung Galaxy Captivate to be recognized by my Win xp when I connect them with a USB cable. This is the same phone I had trouble connecting a few months back. With much help from this list, I was able to get them connected. (Win device mngr, red check mark, get ID, insert this ID in android_winusb.inf file and reinstall android sdk usb driver.) After the fix, communication was successfull for Aug and Sept (about 10 connections per monthduring a 5 day period). But this month the Win xp will not recognize the phone. The only thing that happens is that the device manager, usb, list is updated to include "unknown device" which has no ID's. I have talked to AT&T and Samsung. One person said that there was "an update Oct 5" and this bit of information got me introduced to Samsung tech suppor level 1 and then, after considerable talking, to level 2. Samsung level 2 said that I must have the specific USB cable that came in the box with the phone, I said that probably was not the problem because I have used this (motorola) cable successfully at least 20 times. Then all of a sudden I get a dial tone. So I drove the 20 miles, went into the owners home (while talking to him on his phone, he has mine to use beta testing) and got the cable. Results are the same with this Samsung cable. I am writting this long note becasue I have lots of time waiting for 50 minutes for level 2 support again. I am loosing hope that Samsung is going to be able to help me or possibly they recognize my phone # and know my problem is unresolvable. Does anybody have any light they can shed on this issue?

When I get handed a new and previously unknown Android device (typically from a minor player), is there a way to figure out which components it is made of, such as the SoC, the flash chip, the RAM type etc. (Assuming noone else has posted the info of cause)?
In other words are there any tools (other than a screwdriver) for finding this out directly from the device, preferably without rooting (as some of this info may be needed to pick a rooting method...)?

I am attempting to pull an image from an unknown android device. I am running into a few issues:
When I attempt to pull the image by using the command in ADB : dd if=/dev/block/mmcblk1 of =/sdcard/boot.img I get the error write Error: File too large.
This happens when getting to the 4.0 GB mark, (assuming this is an issue with FAT32)
Is there an adb command to do a rom dump directly to my PC? Is there an application?

I plugged my Droid X into my computer to try and transfer a video I took today. It came up with a Motorola "CD ROM" drive. I clicked the setup file, installed it, then switched my phone to USB Storage. Windows tried installing the drivers and said there was an error. Now when I connect my phone to the computer nothing happens besides windows saying theres an unknown device.

I ran into the first problem with my Droid- and I am sure it is not the Droid itself. I am running Vista32- I have Motorola Media Link installed. When I plug my Droid into the PC, I get a mass storage device that installs OK most of the time, and an "unknown device".. Even when I mount the SD from the phone, I still see no Drive in my computer The unknown device never installs. I have tried almost every suggestion i have seen.. reboot pc..reinstall MML, reboot phone.. no luck

I'm looking for a protocol to secure a connection between a mobile device and a web service. I want to ensure that only the mobile device can perform actions on the web service and vice versa. Data doesn't need to be encrypted. I know Oauth, but it seems that it's more used to secure connections when you got 3 different entities (Server, Consumer and Auth). Here, the Consumer and the User would be the same person. Is there a simple protocol to do that (without requiring the user to login and then authorize the access token like it is the case for Oauth)? I need to use it on different plateforms, so the protocol needs to be available at least on iPhone and PHP.

I am creating an Android application. This application should send message to computer via internet and Wifi (check whether if the device is using internet). The main function is by pressing on a button in Android device a message should go to computer via internet (I don't know, but I think it should be with UDP). I know that I need to set the server for computer and write down IP and port to the android app code. I don't have any clue how to do it. I kinda need to create a computer (windows 7) server receiver, which would receive messages. I am using Eclipse Android SDK

Most of my Android contacts are listed as "device" under the "connection" heading. About 10% of my contacts are listed as either "google" or as "google" and "device". The contacts that are have Google under the Connection heading auto-sync to Google+, the remaining 90% of my contacts don't sync.
Is there a way to edit/change the Connection type to add Google to all my contacts?

I have tried with zero success to get a USB debug connection from a WinXP dev box to a brand X Android 1.6 tablet. I believe I had everything configured correctly on the Android and installed correctly on the dev box, but when the two are connected with a USB cable NOTHING HAPPENS; i.e. Windows finds no new hardware much less a new USB device; therefore, I cannot then install the Android SDK USB drivers on Windows and do the debug thing with Eclipse.
Either the mfg of the Android tablet device has disabled USB debugging and just didn't remove the UI that appears to enable it -- or I've left out some crucial step(s). (The device manual is 100% Chinese and I'm 0% Chinese, so it's no help. The tablet is very nearly, but not, the model A84 7" touch screen 'laptop' at 'www.lezestar.com' in case this helps.)
On the tablet:
- 'Settings/Application/Development/USB Debugging' is enabled.
- Tried 'Settings/Application/Development/Allow mock locations' enabled and not.
- Has 500MB internal flash 'hard disk'
- Has installed 2G SD card
- Firmware: 1.6
- Kernel: 2.6.29-002360g4f8dbbb-dirty
- Build No: 1.7.3
On Dev box:
- Windows XP SP3
- Device Manager finds no 'new hardware' when XP<-->Android USB cable is connected.
- Neither USBDeview.exe (Nirsoft) nor USBView.exe (Microsoft) find any evidence of connection with the Android
- Eclipse Galileo (3.5.2) with Android SDK (for 1.6) and ADV Manager.
- USB Driver package, rev 3. downloaded using ADV Manager.
Other:
- USB ports on both Tablet and dev box successfully connect a USB mouse.
- Tablet and Windows XP have been rebooted often.
Is permanently disabling debugging something that Android manufacturors are allowed to do and therefore I'm trying something that can't be done?
If the mfg has 'disabled' debugging, is there a way to work around this; e.g. download a tool that can change Android OS configuration to reenable it?

I'm developing an App that sends keep-alive packets to its server to ensure the connection is still alive.
The server is java based and thus easily to run. I run the server on a virtual machine (Windows 7). After my App is connected and the first keep-alive packet is received (it displays a message in its console output) I disable the network interface in Windows. This step is very important because by disabling it, there is no way to send any packet back to the client informing it about network changes.
The clients are configured to send every 25 seconds a keep-alive packet, so you don't need to wait long.
When you use the sample JavaClient on Windows 7 it takes less than a minute after the keep-Alive packet and an exception is thrown which triggers reconnection (which currently can't occur). This is the expected behaviour.
When you use the sample Android App on an emulator (tested Android version 2 and 4) it is the same behaviour. So in less than a minute after the keep-alive packet it recognises that the connection is dead, throws an exception, this triggers reconnection.
Problem is now when this App runs on a real device (tested several, Xpearia Arc S, one Cyanogen Mod 4 on Galaxy S3 and my Galaxy S3). I've waited 5 minutes, but there was no exception. This behaviour is reproducable.
Since this is a sample App, it uses no wakelock or service, so to test it is important to have it in foreground all the time (don't switch to other Apps or homescreen) and increase your display timeout to a few minutes to ensure that it doesn't go off. Use Logcat-Output to get informed whats happening, because there is no output in the App itself.
Now Sample-Code is in the attachement. Something had gone wrong. The Code consists of 3 Eclipse projects which you can easily import.

I'm using ThreadSafeClientConnManager to manage a pool of client connections, because my application has several threads, which are simultaneously connecting to a webserver.
Abstract sample code:
CODE:..............
Now lets say on of this threads is downloading a large file, but then the user of my application is switching to another activity/screen. Therefor the file is needless and I'd like to abort this download connection.
In ThreadSafeClientConnManager I found this method: public ClientConnectionRequest requestConnection (HttpRoute route, Object state) Returns a new ClientConnectionRequest, from which a ManagedClientConnection can be obtained or the request can be aborted.
So far I've been using:
CODE:.........
Now from what I understand, I've to use:
httpclient.getConnectionManager().requestConnection(HttpRoute route, Object state);
And that's the point where I'm stuck. I assume that for the route I can just use new HttpRoute(new HttpHost("10.0.0.1")) or whatever my server is, but what to put in for Object state?
And second, as soon as I've the ClientConnectionManager I can call getConnection(long timeout, TimeUnit tunit). But then from there, how I do I execute my HttpGet httpRequest = new HttpGet(URL_TO_FILE); as I did before with HttpResponse response = (HttpResponse) httpclient.execute(httpRequest);?
I've been gone through the documentation and tried out quite a few different things, but I wasn't able to obtain a working solution. Therefor any suggestions and/or code examples are more than welcome.

I'm coding a very basic FTP client on top of my application and I have 2 activities. The first one is the file explorer and the second one is the image viewer. Once I click on the image filename on the explorer, I want to pass the connection to the other activity to handle extra stuff. Basically, I want to keep the same org.apache.commons.net.ftp.FTPClient object (which handles the connection) alive in-between the 2 activities. I know I can't pass an object inside an intent so I don't know what my best bets are.

What's the technical term for being able to have voice connection and data connection simultaneously? Like AT&T was promoting heavily for a while.Apparently, the new T-Mobile Vibrant has this capability. A friend got one and was accessing the web while talking to me, double jealous now.I have benn lusting after the Verizon version, Fascinate, and wondering if there is any chance it will as well.

I was monitoring the traffic on Eclair 2.1 and noticed periodic DNS queries to "android.clients.google.com" after launching IM/Email/ Browser even though the phone was idle and I was not doing anything. why Android generates these periodic queries to "android.clients.google.com"? Is there a specific service generating these queries?

In the past week or so when anyone calls my phone, the number comes up as "unknown". If the person is on my contacts list, their name comes up as unknown & if it's a regular number like my work or Dr office it also comes up as unknown. Even if I make a call, my call log shows the number I contact as unknown, even if I check my voicemail. It's driving me crazy since I always screen my calls. I an on a G1 phone and my carrier is T-Moible.

For an unknown reason to me, after to switched from using the common SQLiteOpenHelper to a custom one which allows me to store my database on the SD card, every 6th or 7th image that is loaded throws a NullPointer at:
imageCallback.imageLoaded((Bitmap) message.obj, wallpaperNumber);
I've checked everything and don't actually know what variable is actually null.

I get the following error
CODE:...
When trying to execute this code in a service:
CODE:..........
When the service is first called and no MediaPlayer-object exists, the stream is started correctly. But when the onStart()-method is called again (with the player streaming) I get the above error code. I can't find any information about this error code, so I turn to you for help. Replacing mp.pause() with mp.stop() makes it work. Could it be that the stream does not support pausing? It's an online radio stream (RTSP) in the SDP format.

If my screen locks while I have a wifi connection, then the connection is lost when I unlock the phone.First, is this perhaps deliberate, to save power? Also, either way, when I unlock the screen and go into wifi settings, I see that the phone is trying to make a wifi connection, but it never succeeds, even though it's my home network and I'm in the same room as the router. It just states 'Obtaining address.

Long time reader, first time poster here. How does one know if the Epic is using the wifi connection as opposed to using the 3G connection? When wifi is connected both that and the 3G connection shows at the top. So which one is in control per se? And how can it be verified?
