General :: Droid 3 USB Connection
Sep 30, 2011
Before the update, when I connected my Droid3 to my computer via USB, the USB icon would come on the phone and its internal storage would show up in Win7 for me to use (pull pics, etc.) After the update, when I connect my Droid3, it simply charges. No icon, nothing in Windows happens.
I know there used to be a setting somewhere to specify what would happen when you connected via USB... but now I cannot find it. Has it been removed, or am I blind?

How to set up my internet connection but I am having some problems. When my services bars are blue, and it says 3G or 4G LTE next to it, I can connect to the internet, or if I am in a, area with wifi, I can connect to that. However, If I am not on wifi, and the service bars are grey (without 3G or 4G LTE written next to it), I can not connect to the internet, get my emails, etc. I have a DROID BIONIC.

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.

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.

Whenever a application needs internet and connection fails, I get a message dialog
Connection failed
This application requires network access. Enable mobile network or Wi-Fi to download data.
and two buttons, Settings, Cancel.
How do I detect there is no internet connection?
How do I popup a same dialog in my application?

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?

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 have a HTC Droid Inc 2 w/ 2.3.4.I am no longer able to connect to the PC. I have it set on "Disk Drive" but anytime I plug into the computer's USB, it only charges without any prompts given. If I do a Fastboot with the phone plugged to the USB, the puter then says "doesn't recognize device". I suppose it must be a hardware problem with the port on the phone. I used to be able to connect with the same phone and computer. Don't I HAVE to plug directly to the PC in order to unlock the security to get rooted?

Big hands + small phone = need for a GOOD phone-to-PC connection app.
Phone is a Medion E4002 (bought from Aldi) running Android 4.1.1. Does everything I want and great value for money.
I've tried a few apps but so far not found anything that easily allows me to do all my phone editing on the PC screen - mainly extensive contacts editing, but also file transfer etc. Texting is a big one too, as I need to frequently send text messages to groups.
I want an app that loads when I want to use it, not when it thinks it's needed - some are really annoying in this respect.
I sit at my desk all day with phone beside me so connection will always be via USB cable. Don't care about other connection types (Bluetooth, etc).

I got a new Droid (new verizon customer) last Friday. Twice now I have lost 3G downsignal only (which effectively means no data connection). To be clear, I still have the 3G signal icon on my phone, and all my apps are uploading data (according to the icon) however no data is being sent back down. I've tried waiting 10 minutes and tried going in and out of airplane mode (3G icon does come back after leaving airplane mode) however I still don't have downstream connection, only upstream.
The only way I have fixed this is to reboot the phone, which sucks. Has anyone had this issue? I'm not sure i'll be able to get a replacement (even with insurance) unless I can reproduce it in front of Verizon reps, so I'm not sure what I should do about it.

We are developing an Android application will connect to Oracle DB. I have problem with JDBC library dependencies.
I always get (java.lang.ClassNotFoundException: oracle.jdbc.OracleDriver) error, this happened when the Class.forName ("oracle.jdbc.OracleDriver") didn't find the JDBC library. At my case I double checked that my ojdbc6.jar library is existed correctly at build path.
Is there any farther configuration I've missed ? Regarding libraries dependencies, is there any difference at development between J2SE and Android application ?
IDE: Eclipse SDK 4.2 with Android
Android target platform: 2.3.3

I just spent the day looking for what the limits are for Android v4.3 limit on the BLE connection parameters.
Such as:
-Interval Min
-Interval Max
-Slave Latency
-Supervision Timeout
No luck, Apple is nice enough to document all of these in their Bluetooth Design Guidelines, but Google hasn't been so nice.

I'm wondering if there is a good application for my droid that will use the GPS to get me around with a preloaded map database so that it doesn't rely on me having a data connection.
Edit: did some research, looks like osmand and mapdroyd are the best choices. Any user opinions on which is better and why?

I installed freedom about two months ago and ever since I've been getting the " No Connection Error". I've tried these and have
1. Resetting the phone ( both through settings and service menu. )
2. Re-installing Freedom, opening it and manual closing it, clearing data and uninstaling.
3. Made sure the # is in front of the second IP address in the host file.
4. Uninstalling and re-installing play store through Lucky Patcher
get the play store working again.

I have a nasty problem with the adb and my Galaxy Nexus (CM10 nightly-20120926). The ADB seems not to work properly. Every time I start my app within Eclipse it gets installed on my Galaxy Nexus and the LogCat window show some output. So far so good. But suddenly ADB stops writing messages and the "Console" windows shows a lot of messages like:
Code:
[2012-09-26 21:01:15 - DeviceMonitor] Adb rejected connection to client '2930': closed
[2012-09-26 21:01:15 - DeviceMonitor] Adb rejected connection to client '2459': closed
[2012-09-26 21:01:15 - DeviceMonitor] Adb rejected connection to client '2459': closed
[2012-09-26 21:01:17 - DeviceMonitor] Adb rejected connection to client '2610': closed
[2012-09-26 21:01:17 - DeviceMonitor] Adb rejected connection to client '3079': closed
[Code .......
From now on the ADB does not output messages any longer. I have to reconnect my Galaxy Nexus to my USB-Port to restart the debugging.
And some messages I generate by using "System.out.println();" are never displayed also!
My onCreate() method looks like
Code:
@Override
public void onCreate(Bundle savedInstanceState) {
super.onCreate(savedInstanceState);
setContentView(R.layout.activity_main);
System.out.println("ON_CREATE!");
[...]
But "ON_CREATE" will never be displayed!!

Is there an app or a script I could run to tell my phone not to connect to wifi when 4G is available..? I run with wifi on all the time and have a handful of networks I connect to but would like the phone to automatically disconnect from wifi when 4G is available then reconnect if it is lost. This is useful for me at work because depending on where I am in the building I may have 4G/3G/no data but the wifi is everywhere but it is unsecured so I'd rather not use it if I don't have to.

how I wound up with this but after a factory reset I noticed that in my phone contacts there are all these "connections" with a chainlink type icon. I didn't have these things before my factory reset.
I don't sync with Google, I use Companion Link and DejaOffice. DON'T want to sync with Google. I can't find a way to "un-connect" and get rid of these things. If I press on them, I get an option to add a connection but no option to disconnect that I can see.
I'm assuming this is either an Android or another one of freaking Google's attempts to invade a my space, privacy and run my life and I don't like it.
