Android :: Application For Using Camera Flash For Notifications?
Apr 25, 2010
Being relatively new to my Droid, I'm still finding fun stuff. Recently, I picked up the shell/holster combo and really like it. However, while I am at work, I have my phone on vibrate (thanks Timeriffic) and can't tell who is texting/emailing me like I used to (different colors for the LED, thanks Handcent). What I was wondering is: is it possible to write an app that uses the camera flash like a vibrate function.
The ability to customize the number of flashes and duration would be cool, as would the ability to have it only flash when the phone is on vibrate or silent. Preferably, without having to root the phone. If its not possible due to hardware or software lockouts oh well.

My app is using the camera on the phone. For phones w/ 2.0+ I have been able to activate the Flash. When I test on a phone with 1.5 OS on it the app crashes. I get: java.lang.reflect.InvocationTargetException and the Cause is java.lang.VerifyError: fishers.Nav.TakePicture$1
I assume because you have to access the flash differently in apps below 2.0? Can anyone give me some advice or links to examples showing how I could make it work over the whole range of Operating System version or is that just not at all do-able?

Has anyone found a FlashLight App that uses the dual LED Camera Flash as a light source? I have this on my BlackBerry Storm and it works Awesome. Have not had any luck finding one like it for the DROID?

There is an app in the market which is written just for the Moment that uses the camera flash as a flashlight -- essentially it turns on the camera flash. The application says not to use the flash "too long" or damage may occur, but the "too long" time period is not defined. First, will having the flash on for an period of time damage it? Second, if so, any idea what maximum period of time would be "safe?"

Is there a particular flag that we can use to prevent apps showing up in marketplace which require the phone to have a camera flash /LED? Typical apps are ones which make the phone act like a torchlight in dark. I have seen a tag which prevents apps requiring auto focus in a camera from appearing in the marketplace. Just looking to find out if there is something similar for camera flash.

My camera stopped working. When I click my camera application I get the message "The application camera (process com.android.camera) has stopped unexpectedly. Please try again". It's just a blank screen?

If you could only choose one of these, which would you have chosen for the Fascinate? (Obviously it would be best to have both).

Is there a way to turn off the LED notification for Gmail? I went into the LED options and unchecked "Email," but I'm not sure if that's just for the "Email" app itself, and not Gmail. I still get the LED flash when I have new Gmail, but it doesn't seem to happen *every* time! I still want the notification icon to appear, so I don't want to turn off Gmail notification altogether. I already turned off sound, now I just need to turn off the LED.

I would LOVE to have any of my LED flash notifications from missed calls, text messages, or voice-mails flash continously UNTIL I acknowledge or clear them. Right now, the notifications flash for a few minutes then time-out.
1. Does anyone know how I can keep these notifications flashing until I clear them WITHOUT a 3rd party app? If so, please do tell... If not, what app would you suggest?
2. Lastly out of curiosity, anyone have a clue what the "pre-determined" time frame is before the flashing times itself out?

Is there a way by which I can control the camera flash at the back of the phone? I want it to be on for a certain period of time during my app.

I hate trying to record something at night or in a nightclub with my Moto Droid because it looks like crap! All dark and not viewable. So my question is, is there an app that will turn on the camera's flash and use that for the video camera? Im trying to find something in the market.

I'm trying to use the camera in an Android app using the 1.5 API. I want the camera to flash for every picture. However, when I looked at the API for camera.parameters, the setFlashMode() method is only supported for 2.0 and higher. Yet my Cliq XT, which runs 1.5, has a flash that I can set in the menu - I take this to mean there is a way to do this for the 1.5 API, though I was unable to find it.Does anyone know how to set the flash mode using the 1.5 API?

Is there such an app that can make the camera flash LED work as a notifier instead of the notification LED?

So how do you turn on the camera's "flash" LED in Android? (like flashlight apps) - and is it possible to vary the brightness?
search results for "android flash" too polluted by adobe flash..

My Flash on the camera has stopped working all of a sudden. I checked the camcorder and the light (flash on) didn't work. I tapped the back of the phone near the flash. It worked. I went back to camera and turned on flash, it worked. So by tapping something I jigged something around in there and the flash was working.

The camera flash on the Incredible is killing me, it basically blurs out everything in the picture, especially a face! Anything white in the picture will have not detail or definition when you use the flash to take a picture.

I tried to start the camera flash for an app I'm doing but I don't understand why it isn't working.
here is the code:
Code:
import android.app.Activity;
import android.hardware.Camera;
import android.hardware.Camera.Parameters;
[Code].....
For information I'm using a LG Optimus 3D for the test of this app.

Will the android version 2.1 update provide the X10 a proper flash LED when taking photo's? Currently, it's somewhat cumbersome to go all the way into settings to turn on the LED light (that stays on until you turn it off) just to take a well lit photo. So I'm just wondering will the LED flash on the new OS update provide the automatic LED flash?

Bought a HTC Desire and just cannot get its camera flash working. Obviously having hard time with people at the shop ("have you tried taking these pictures at night, maybe it understands that it is still daytime even if you tried it in bathroom"). My dumb brain would suggest that manual - flash always on (unless that 5% battery limit is not hit), automatic - depends on sensor income, off - no flash. Really hard to search for stuff like that in forums as usually "flash not working" refers to Adobe Flash.

When taking pictures in low light, my flash seems to be way too bright. It completely washes out almost the whole picture. Any special settings I can use?

Hey there! I've been looking but with no success so far. Does anyone know if there is an app for the Eve to turn the camera's led flash into a torch? I've found a few that use the LCD light, but that's not intense enough... And all the apps I found so far that use the led flash light, do not work on the Eve.

I've noticed since the Froyo update that when I take pictures, the camera flash is so bright that objects/people turn out completely white, depending on the distance. Is anyone else experiencing this?

I've been stunned by how different Samsung's camera behaves compared to the other devices I've tested camera preview stuff with.
Mind you, this is in 2.1 so the SDK 8 Camera.getZoomRatios() and Camera.isZooomSupported() are not available.
Looking at the Camera.getParameters().flatten() result shows that the common "zoom-supported" that I see in HTC, N1, and Mototrolla devices is not there.
Instead there's something called "digi-zoom". I couldnt find any documentation or posts about its usage but a little experimenting revealed it takes numerals 1..10 as string and will zoom accordingly. I have no idea what the ratios would be.
Also, there's some madness with the flash mode on the Galaxy S Epic that I have tested with.
Calls to getSupportedFlashModes() return only auto,on,off. There is no torch supported.
However, if you do params.setFlashMode(Camera.Parameters.FLASH_MODE_TORCH) it will turn the LED on!
Sadly, subsequently setting it to FLASH_MODE_OFF or FLASH_MODE_AUTO does not turn the LED off! It's stuck on until Camera.release(), or maybe Camera.stopPreview(), I havent traced into it yet to see which actually turns it off.
I suppose that's why Samsung doesnt return torch in the supported list. I'd prefer not to have to stop and restart the preview to turn it off for this model.
