General :: Cannot Connect To 3G Service
May 2, 2013
I got a Star N8000 with android 4.1.1 1 month and a half ago and I think its a great phone... anyways the point is that when Im connected on wifi everything is perfect, notifications aren't delayed at all but when I use data mobile its different =/ when the screen turns off for 5 mins or something like that, notifications are quite delayed... sometimes I have to turn on the screen and wait like 20 secs after I open whatsapp and all messages start to come. I dont know why I cannot connect to 3G service, maybe its because Movistar doesnt have it (Im from venezuela) so I use EDGE and I figured out about something: when I open whatsapp (after inactivity) it starts to try to connect I think because in the signal icon appears two white signs like an arrow or something like that. I dont know if it the software but it doesnt happen on wifi:.. so I dont have any idea about it. Im not root user (tried to be but didnt work) and I dont have any task killer..

I'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.

I have an android app that must connect to my local webservice with soap but I cant seem to get it working. This is the code I have.
[HIGH]public void Hello()
{
String SOAP_ACTION = "http://tempuri.org/Hello";
String METHOD_NAME = "Hello";
String NAMESPACE = "http://tempuri.org/";
String URL = "http://10.0.2.2/MainService/MainService.asmx";
[Code]...
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.

I'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.
Here is the Photographer activity:
CODE:..........
And here is where this activity gets called from:
CODE:............
Having trouble pasting the relevant portions of AndroidManifest.xml, but I have permissions for Camera:
CODE:..........
Here's the Photographer part:
CODE:..............
Also set for testing on G1:
android:debuggable="true"
and working off of 1.6:
<uses-sdk android:minSdkVersion="4" />
All this works on a 1.6 emulator, but when I run this on the G1, LogCat shows:
CODE:.............
And /data/anr/traces.txt shows:
CODE:................
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...
CODE:............
The method it crashes in is..
CODE:.........
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?

I had a moment in the beginning and took it back,got a hero had massive problems and finally got my hero replaced with another moment that was brand new.I just got it like 2-3 days ago and its having the same issues that i had on 1.5 when i had it the first time.I had it replaced when i had it the first time and same issue.I have 2.1 now and the battery life is still horrible like dropping not long after taking it off the charger without using it but biggest problem is that the phone will tell me i have no service and it will have an x up above where the bars should be and i have to remove the battery and put it back in before it will work again.The data does the same thing and i can turn the phone off and back on for that and it will work again.Does this happen to anyone else??Its very frustrating!!Also the wifi wont connect.It just says it is unable to connect but it was just working and my laptop works wirelessly so i know that its not my router or anything with my connection.

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.

I've experienced quite a lot of problems with the WiFi after updating the Andriod. Everytime I try to connect to my home-network i get that it failed to connect.
The phone didn't have any problems with this before the update.
Anyone had the same kind of problem, or anyone that has a smart fix for it?

I have a service running in the background.I have a background thread that gets a reference to the service from the application's main activity. But when the background thread calls a method in the service to display a toast, I get the "Looper not initialized exception".Why,if I have a valid, bound reference to a Service, does this still happen?

I am trying to run the sample soft keyboard included in the SDK. I am using the debugger, and the literature says that to use a breakpoint while debugging a SERVICE, I need to include:
android.os.Debug.waitForDebugger();
So here is the portion of the code I modified:
CODE:...........
I have put a couple of breakpoints, at the statements indicated by the comments.
This is what happens: the debugger first stops at the breakpoint1, for a few seconds. But then the service restarts. For the life of me I can't figure out what makes the service to restart.

My service works exactly the way i want as long as i use start and stop and communicate using intents. However my activity needs to change the state of my service as well as retrieving state information.So i thought it would be nice to broadcast some kind of state_changed event from my service and use a binder interface to pull information from the service or change the services state based on user input.This works fine too. The only problem is that my service gets killed when i unbind it just as the documentation says.Is there any way to keep the service alive but still get an interface to control it directly. My activity offers the user a way to stop the service and the service kills itself anyway after it's work is done but i don't want the service to stop every time the activity is destroyed.

I recently bought a Samsung Galaxy S3. It has Android 4.0.4 (ICS). However, when i tried to connect it to my VW EOS via a USB cable, the car failed to recognise the device. It worked with my previous phone, an HTC Desire. Upon reading a wee bit, it looks like ICS drops USB Mass Storage support in favour of MTP. Is this why the connections doesn't work?

I am the proud owner of a SGS3...But I'm not the biggest fan of touchwiz and I love everything about 4.2! So like many others, I flash a 4.2 custom ROM. AOKP 4.2 build 2, to be exact.After flashing, I loved it. Everything about it was just perfect. It was fast, light, easy to use, and FAST! But then I go to take a picture. And boom.
"Can't Connect to Camera"..I had no idea what to do, so I did the first thing that comes to mind. reboot. But sadly, this solved nothing. So of course I re-flash my touchwiz ROM to see if the ROM was the problem. And the Touchwiz camera worked perfectly. Later on when I had time, I tested it out again, and had the same problem. So I downloaded a camera app, and same thing. I even flashed a different Camera.zip for God's sake! I've searched for the past week for fixes and every one I tried just failed! So now I'm really done with Touchwiz and want to customize the look and feel of my phone (which is one of the reasons I like AOKP!)
It seems that my camera only works on Touchwiz ROMs! I also tried another ROM this time running 4.1.2 thinking maybe it was just a bug in 4.2! But sadly, the same error message.
I was flashing a 4.2 camera .zip file and i guess it was messing up the permissions. So I disabled it. Now it is working perfectly so far. Yesterday i switched over to a 4.1.2 ROM hoping it would fix it and so then i flashed this 4.2 camera and then after about a day of use, it messed up the permissions.

I got a chinese X12 dual sim phone because i really needed only 1 phone (had to carry around 2 of them).Phone works great, only problem is with the mobile networks. It can connect to GSM networks but it won't connect to a 3G network. The phone has 3G capabilities, 3G is enabled for the required sim, it finds the 3G network but it will not connect to it.
Sim works fine, had it in a Samsung i900 on 3G (WCDMA) The thing that surprises me most is that the phone came with android 4.0 instead of the 2.3.6 it was advertised, could this be the problem?
