How To Start Camera Flash
Jul 18, 2011
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.

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 any way to start the camera app from the lock screen? Whenever I use the camera icon and swipe it over, it prompts me to enter my PIN number.
I just want to be able to take photos, without unlocking, iPhone style.

Is there any way, with root access, to change the search button to make it bring up the camera app instead of the search app? i have never used the search feature, nor do i plan too, however i use the camera quite a bit and would like to have instant (well, close too) access to it. *just to verify, i am talking about the hardware, led backlit, search button...obviously not the onscreen search button...just wanted to be 100% clear

possible to prevent camera app to start automatically rotating into landscape with just the icons adjusting to portrait/ landscape view? I find this real annoying because not just the pop ups are always in landscape but also it does not start or close smoothly and by the way it looks ugly..so is it be possible to make the camera start as other apps in that mode I actually hold my phone?

I really have no use for it otherwise. I would like to be able to click on it and have camera pop up if possible.

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.

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.

sorry if someone answered this but I couldn't find it, is there an app for using the flash as a flashlight without going into the camera app? I would prefer a toggle switch like the one made by curve fish, Sent from my ADR6300 using Tapatalk

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?

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.

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 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'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 was certain I'd seen another post on this, but can't find it. Since Froyo, my camera doesn't work with flash. Even at 90% battery I get this message: Flash is disabled due to low battery power, cold weather, or a running application that uses a lot of power, like Wi-Fi hot spot and phone. I haven't got a LED flash torch thing - I uninstalled that before updating to 2.2. Ideas?

I noticed at some point after the upgrade to CL14 (done via sprint) that my flash on the camera isn't working. This could have been happening before the upgrade but i doubt it.
Anyways so the camera doesn't light up the flash. I saw it light up the flash once since I started troubleshooting but thats about it. I switched back and forth between flash on/off a dozen times or so.
Downloaded momentflash. Low and behold i started the app and it worked! Then i tried turning the flash on again and no luck. So i uninstalled, rebooted phone over and over again, no luck. I then did some reading and realized there was a widget. Put that on the desktop and again the FIRST time i ran the widget the flash worked. then it stopped again. I haven't been able to light it up since then.
I haven't been able to do much troubleshooting when it does work, but it doesn't seem hardware related. it stays on until i hit off, but i didn't get a chance to wiggle it around to see if contacts needed cleaing, etc...
Just wondering if anyone had any ideas? I don't think its any apps i have installed as i have pretty standard ones and had those on when it was working ( i believe at least).
i also tried killing all my running apps to see if any were causing conflict, then restarting momentflash and it still wouldn't light it up...
any help would be great, I don't really know what else to try. Looked at the android logs and nothing jumped out as having an issue.
I could probably try hard resetting but don't want to restore the phone again if i don't have to.

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?

First, is there a good reason the captivate does not have a camera flash (aside from the devs thinking the night mode worked 'well enough')?
If not: I strongly suggest we get a huge number of people to say they would be interested in buying a flashlight/camera flash add-on for the phone were someone to develop one. After we get a big enough number, we'll kindly forward it to several companies. I took my phone out last night for halloween, and was quite disappointed with the night quality. I'm sure something like this would be profitable at ~$6, but I would pay $10-15 to cover research costs/etc.

Does anyone know if the Incredible, or any Android phone for that matter, has a camera flash setting to reduce red eye? I just got my phone a week ago and have been playing around with it but I haven't see a setting for it.

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?

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.
