[Development]Edit Htc's Camera app

---

Hi folks!


I've been searching this section for an answer about editing the stock camera-app. Without any success at all (except by briefly sentences about this).

The goal with this is to make the flash to light up right before the application tries to focus. This will make it a alot easier to take photos in more dark places. (And for those with a past of nokia devices) you already experienced this function.

I've attached a .rar-file containing the following:
1. The original .apk file
2. The decomlied .jar file
3. A folder containing everything from inside the .apk (for those of you that haven't a clue at all how to extract files from a .apk file)

Well if you are following this thread, you probably already know what's going on.
But for new visitors: I decided to change my approach to several problems I stumble upon. So I will more likely create a complete new camera app specific for the DHD. And yes, users to this forum will be the first to try it out. But I've haven't decided yet how I will distribute the app, if it will be through google marketplace, or just in here (or what ever it will be).

But if this project take up to much time, I would appreciate some kind of donations But of course after you folks seen some results
So keep tuned for more news!

Still stuck at succeeding to complie back to ordinary apk-file again. So if there is someone with any kind of knowledge about this, please let me know.

Well guys, I succeeded to change some values, but I still got some problems to complie it back to .dex
Maybe an update about this during the day

I've succeeded to find the class containing all definitions (for an exapmle: how many seconds it will take for the timer to take a photo).
I will try to edit some values and the complie it back to .dex (in other words make it back to .apk).

I hope to update before the end of the day.
Cheers folks!

I've manage to decomplie classes.dex in HTCCamera.apk to a .jar-file. So if you got a java complier it shouldn't be any problem to open up the file.

The main problem right now is to find which class that handles the actual moment when it tries to focus. So if any one with some sort of knowledge about programming have some time over, feel free to help me find this specific class.

While it's a good idea, what I do is extract the torch app from Cyanogen Mod, then put it on and go home, because the torch will stay on until you go back on the app and shut it off, so I use the torch and then I launch the camera, try it!

I don't use Cyanogen mod, can you upload that apk somewhere?

A more pressing matter is that when a video is recorded, audio is compressed and encoded in such a low quality. As a result, the audio is very bad. Here are some ideas I can give you. Reroute the microphone input from back to front mic. In other words, the mic we use while talking. Increase quality to at least 128kbps and 44100Hz frequency. And disable ACG. I assure you, doing this will benefit the whole of the Desire HD community I'll gladly donate once my EMA comes in next week

Well, it's a solution ^^
But not one I want to use. I don't want to luanch two applications just to take one picture.

But thanks for the suggestion





Elemental_Fire:
That is exactly the kind of things I want to change

Glad that someone is finally doing something about this.

I just don't understand why this function is not found in DHD.
Without it, most photos taken in the dark are blur as there is not sufficient time and light for it to focus correctly.

I personally don't like to use 3rd party application for camera. Therefore I hope that your work would interact with the phone camera and make the LED flash to bright up automatically without any additional application or with "one time setting" only.

Fingers crossed for this...

Any progress made? Maybe some ROM developers could take a look at it?

Well, sorry guys for my inactivity. But I got som studies in the way, so I hope there will be som extra time over for this

So stay tune for more news

Hmmm, loving the idea. I'm also wondering about pausing in video recording, like pause-continue recording-stop etc, like in nokia's too

Looking forward to updates here. Hopefully you can do something about the god awful audio quality.

@Elemental Fire..as far as i know, there is only one mic on our DHDs, the mic you use to talk on phone calls at the bottom. There is no other mic.

edit: this thread should really be moved to the Development section. There would be a lot more activity there and more who could help.
