This is not really a developer question but not sure where else to ask. I'm getting close to making a video tutorial for my android app. On windows I used something called "demobuilder" which is pretty cool, it records the screen as you demo your app (with voice over) and it produces a flash video.
I've been looking for something like that for android but haven't found anything that captures the screen to a video.
Can someone recommend an app that will help?
The alternative is pointing a webcam at my tablet which I think is a bit unprofessional.
I had the same problem sometime ago. Like Michael said, it is hard to capture at full frame rate from the Android (or the emulator).
I ended up using Screencast for android. However, what I would probably do now was getting something like Elgato. You connect the device trhough HDMI to that box and it allows you to record the HDMI output signal.
Another approach is to build your app for Android-x86, so that it'll run on your computer without emulation. At that point, your usual screen cast tools all work.

I like this concept as shown in the YouTube link
But not sure how it is possible for real application. Is it possible to implement as shown in the YouTube. SamSung has GalaxyBeam, but the projector is at the top of the phone. I like to use the flash light as a projector. Is it possible to develop or silly idea?
Thanks
Cute concept...
In the video, how the screen is beaming on the wall is by using airplay. If you purchase a projector with airplay feature, you can do the same.
Using the built in led of the iphone as a projector (like seen in the video) is just a concept and currently not possible. They also used airplay for filming this concept.
I don't think that such a feature will even be in iPhone6 and I'm sure it will create battery issues...
There are some 3rd party options. You may check one of them
I am looking for a way of displaying an analog video stream on an android phone. On a pc/mac/etc you can achieve this using a cheap usb analog-digital converter such as a grabby: http://www.terratec.net/en/products/Grabby_82248.html, and then view on VLC, for example.
Would such a thing work (in theory) on android if the proper drivers were available? (ie. are there any hardware issues which make this impossible?)
Does anyone know if such a device with android drivers is available?
Ultimately I want to make an app which interfaces with the grabby (or similar device) and allows the user to view video on the android and capture and send short clips.
First of all the Android device needs to support USB Host. This limits your userbase significantly.
Then there is the problem with power. Some USB Host devices will be incompatible simply because an Android phone will not be able to push enough power through to port to get it running properly.
I'm not sure about the drivers, but I'm 99% sure it won't work "out of the box".
You should certainly take a look at THIS project. It is pretty similar to what you are trying to do. Maybe you should consider getting in touch with that person.
EDIT:
Based on what it took to get that DVB-T dongle running in the project i mentioned above the chances of creating an app that everyone will be able to simply download and use are EXTREMELY slim. Getting that dongle running required using a modified kernel and special scripts. Of course I could be wrong. You can continue the research yourself or wait for someone with more experience than me to reply.
I want to make an application that uses the android camera, but I want to test it using the emulator. I don't have a webcam to use for live image, so I want to know if I can do it faking a still image (somehow) or I will need to use something like a fake cam on my desktop pc, and then make it be used by the android emulator.
I searched about some solutions but they appears old. Anyone is using something like that and can point me to a "fresh" solution?
for the documentation of a project I would like to record the screen of my Nexus One as a movie or at least in form of a lot of images, which I can convert into a movie. Is that possible? Is there an app for it? For the moment I only know about this screen capture functions in the SDK's tool directory.
I've use two tools and both work well:
Androidscreencast fps 4-5
Droid#Screen fps 30
Do you need it from the device itself, or would from an emulator do? Here is a Nexus One Emulation Skin.
Here is information about the Dalvik Debug Monitor which claims to:
which provides port-forwarding services, screen capture on the device, thread and heap information on the device
(emphasis is mine)
I am not an Android Developer, so I can't comment on the usefulness of the tool.
As far I know you can only record screen of an Android device from a PC.
You need to use a tool that will put the phone's screen onto PC.
For this you can use Droid#Screen . I use this tool for presentation purposes. Than on PC you use whatever screen recording app.
It is raithe handy to use android 4.x builtin method via adb shell screencap. I wrote a basic PyGtk adbcap wrapper to make it even more simple to use.
More or less as it says on the tin.
Before I even contemplate downloading the SDK, I was wondering if there was any way of testing Android apps that I'd write without an Android phone available to me? I'm unsure as to whether or not the tools that come with the SDK come with an emulator like VS does for Windows Mobile.
Sorry if this is a stupid question, but maybe I'm searching for the wrong thing.
Edit I don't suppose there's anything that'll let me write widgets on/for an emulated version of the interface HTC use on the Hero/G2 either is there? Not that it would matter that much.
There's an emulator available as part of the SDK.
http://developer.android.com/guide/developing/tools/emulator.html
I'd add that the emulator is really quite comprehensive. Things like camera previews don't actually display camera data, but they put block animations in their place. All in all it's one of the best mobile emulators I've seen to date. Probably better even than gasp the iPhone simulator.
As said above there's an emulator available,however with larger apps it gets fairly tedious to use the emulator.Its fine for learning the ins and outs but id suggest investing in an android phone once you've got a good grasp of the sdk,it really does make a difference!.
