Android :: Fail To Connect To Camera
Apr 1, 2010
I'm using the Android APIDemo sample code.
When I run the CameraPreview example, at first it was giving me an error.(http://stackoverflow.com/questions/2556389/android-camera-functionality-howto)
I traced that one down and the sample was working for a while.
Now, it no longer works. It says ERROR/AndroidRuntime(2949): java.lang.RuntimeException: Fail to connect to camera service
What can be causing that? It happens when camera.open() is called.

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?

When it comes to smart phones and flashing. I recently got a HTC Evo and had it flashed to be on metro pcs to try and save a little cash on the bill. Well I think I am learning you get what you pay for. I am hoping I can get some tips or tricks from this forum. My phone will not run any apps really. It wont connect to facebook or the app store or google maps and youtube. Basicly all the social apps dont work. However if I connect it to WIFI it will run it them. Is it cause metros data service sucks.

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 don't know how to reconnect my camera to my tablet. I get an error message saying "Cannot Connect to Camera". I have a 10.1 tablet by Hannspree model #SN1AT7 (HSG1279) otherwise known as HANNSpad. i don't know what happened. I installed an update and it just didn't work after that.

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 am running a CM11 nightly of KitKat 4.4.1 on a VZW Note II, however I have had this issue with other devices, carriers, Android versions, etc. so I have always assumed it is just the way Android works.
Basically if an app that is currently using the camera (Camera app, barcode scanner, etc) crashes or hangs and gets force-closed, opening any camera app after that seems to always give me either a "can't connect to camera" error or a black screen instead of the viewfinder. In these cases, a simple reboot fixes the issue and I can use the camera again, but this is inconvenient for two reasons:
1. A reboot on my phone takes 45-60 seconds, by which time whatever I wanted a picture of is usually gone or changed.
2. Rebooting means that any apps that don't save the data constantly but run in the background are restarted and I lose the progress. Mainly I am referring to Chrome incognito tabs, but also apps that don't save in-progress data such as puzzle games or video players.
With my limited knowledge of Linux and my slightly less limited knowledge of operating systems in general, I know that sometimes a temporary lock file is Created to prevent other apps/programs from modifying or accessing a file or program until the lock is released. Does that kind of situation apply here, such as a camera lock file being created when camera access is started and then not able to be released if the app crashes.? Also, if that does apply, would manually deleting the lock file or creating a script that does it for me when it is run allow access to the camera again without rebooting? And if that doesn't apply, is there any way to regain camera access without rebooting when this occurs?

I just got a Star N7189 with android 4.2.1 and the first thing I did, because it was a used phone that my dad gave me, was to perform a factory reset.My dad told me the phone was fine except the camera didn't worked, so I thought the factory reset could also fix this.
After the reset everything in the phone is fine and running without any problem except the camera. In first place there isn't even a camera icon or app, the only way I can access the camera is by sliding the screen after I press the lock/unlock button, and after a second of thinking it gives me the 'can't connect to camera' error.I haven't installed any application or anything.

I'm super happy with my new Hero. But I use an external compact camera to make pictures.
Is it posible to connect an external camera to the HTC hero using a USB cable (and an app)?
This would be supercool when we are on the road without a laptop.

I have a Goophone s4 mega running 4.2.2. I was using the camera and it stopped suddenly. And now when I launch the camera app it says can't connect to the camera. I've looked into it a little and I think I'm missing a folder in the system directory called cam data or cameradata. Does that sound like it could be stopping the camera?

Every time i increase my database version and push the upgraded app to the users, something weird happens.. For some it works perfectly fine, and some report crashes (including through the Market's reporting system) caused by the lack of table columns i just added in onUpgrade.
If you want to see the method:
http://code.google.com/p/tag-todo-list/source/browse/trunk/Donut/src/com/android/todo/data/ToDoDB.java#136
I can't spot any exceptions that appear in onUpgrade. What i'm currently doing to bypass these problems is intercepting the exceptions where the new fields are invoked for the first time and then calling onUpgrade 'manually', which is kind of dirty.
Also, the app sometimes generates a 'no such table' SQLiteException when accessing the main table (again, only for some users) which is incredibly strange... Does someone know why these things happen? Or can you spot something wrong in my code?

I downloaded the SDK 2.0 toolkit and tried to launch the android tool to download the latest SDK. The application seems to launch with the following output:
$ ./android-sdk-mac/tools/android Starting Android SDK and AVD Manager No command line parameters provided, launching UI. See 'android --help' for operations from the command line. $
That's it. Nothing happens, no UI appears or any processes are started (check with ps, but there is no new java process). I'm running this on Mac OS X 10.5.8. The previous SDK s runs fine.

I'm struggling to understand why startActivity runs properly when copied from a tutorial I found and fails when I make the smallest change.
Code from the tutorial:
CODE:........
That works. When I try to change it to what I would consider a simpler design, I am getting an error.
CODE:........
The error is: The constructor Intent(FirstTwoApps.ButtonHandler, Class) is undefined
Notice that all I did was moved the action from the handleButtonClick() method to the onClick() method. Apparently that is not allowed, but I don't understand why.

Dunno what's going on. When I first got my phone Pandora was flawless. Then after awhile it would fail to load songs and lockup (I'd have to kill the process and restart Pandora to get it to work again). Then it got to the point where it would randomly stop mid-song and just skip ahead on its own or fail completely. Now it won't even load. None of my stations load at all. I'd rather not have to resort to using a different service, since I have my Pandora stations setup nearly perfectly

You think that google would put forth a much better effort for the email app on Android but ironically, its just a giant epic fail Inbox view only? WTF was Google thinking? It really does suck that i have to use the web app in order to have the full functionality of gmail. I understand Google is moving forward with web apps and the cloud and all that but damn, they leave us hanging like that?
