I want to write an game for Android. To present it very well, it has to have an YouTube movie in the Google Play Store.
How can I do this? Because ADB only produce a slideshow, because it's to slow. Is there an app for recording out there?
PS: I only have Tegra devices (Galaxy Nexus and Nexus 7), so http://pkg.to/com.ms.screencast doesn't work, yet.
The new Android 4.2 has a wireless display feature allowing the send the screen's content to TV screens etc. As you have Nexus devices I guess you'll get the update very soon. I do not know the technical details but I'm quite sure there will be possibilities to record the sent signal.
See this anouncement: http://www.android.com/whatsnew/
You may want to try using the emulator and record using a regular video recording program such as FRAPS. The performance of the x86 emulator has improved greatly and also supports GPU emulation.
Here is a page from the Android documentation outlining how to enable hardware acceleration for the emulator:
http://developer.android.com/tools/devices/emulator.html#acceleration
The downside to this approach is that multi-touch gestures aren't easy to do.

I have an app which I have built for Samsung Gear VR with Samsung s6 device. I would like to show the view of the running app in the headset to the audience in the presentation.
Buy a google chromecast and try streaming to a TV or a projector. Note hovever that this may affect the framerate.
I looked into this yesterday and found one of the simplest ways of doing it was to install the Mobizen app on the 'phone and then log into the Mobizen site.
This mirrors the display and allows full screen.
As mentioned in the other answer, it also slowed the framerate and reduced the time before the 'phone needed a break to cool down.
I want make mirroring android application.(Sender)
I wrote question about "mirroring" yesterday and..
I got "Presentation APIs" -API 17-.
(http://developer.android.com/reference/android/app/Presentation.html)
But, I still don`t know how can I access screen video stream.
Therefore, My question is this.
How can I make packet that phone`s screen stream?(both video & audio)
Is ADT provide APIs about mirroring?
Is it need root privileges?
I found mirroring APIs for only SAMSUNG Galaxy phones.
But I finding android common API.
Please help me..
Thank you.
The latest version of Chromecast App allows screen mirroring - at least for certain devices like Nexus 5, 7, 10 ... So I don't think it would make much sense for you to pursue that.
I'm on Windows 7 with i7 processor and I'm trying to use Android SDK Emulator. However, when I set pixel density to 320 and turn GPU emulation on it starts to lag and freeze and its browser is almost not usable (it's like 1 frame or less per second).
So far with the below settings it's much, much better and I would qualify it as 5 to 10FPS which is usable but it's not 30FPS (smooth usage).
Abstracted LCD Density - 120
GPU Emulation - NO
Keyboard Support - YES
Can anything else be done to make it work smooth except moving to Linux? I noticed that GPU emulation impacted the performance the most.
The most important setting is your architecture, make sure you are using an Intel emulator. The speedup is tremendous!
A how-to is posted here: https://stackoverflow.com/a/10772162/1741111
If you are trying to achieve that 30FPS mark, forget Android emulator and switch to Genymotion.
I was working on Android emulators for 6 or more months before i discovered Genymotion emulator and what difference that has made to the speed of development.
If you are still developing on Android emulator - go and give Genymotion a try. You will thank me for that. Its a huge difference.
There is a free version for individual developers.
Even though this is an old post. I think this needs a mention here.
You don't need to buy a phone. The emulator is a great tool, however very slow. You can enable hardware acceleration to make it run smoothly. Follow the steps on the developers page and you'll notice a remarkable difference in the speed. AFAIK the settings you mentioned do no have that great influence on the speed.
I have wrote a short blog post on speeding up the emulator and adding Google map support:
the first part will be relevant to you. try the Hardware acceleration and tell us what you think:
here is the post:
Speeding Up the Emulator
The best emulator is to buy a simple Android Smartphone and debug/run your apps on this device. I'm doing this and it works wonderfully with no laggs
I am trying to do a demo on a android device, but the screen is too small so is kinda hard to do a demo let say in a meeting room with 12 people. Although I can pass the device around the table or just simple borrow or get more devices for the demo purposes.
I understand there are devies where you can buy special USB converter to do TV-out like in iPhone, and some specific devices on Android (e.g. Motorola Incredible?) But I have to demo on a specific device where it runs standard Android build.
I understand I can do it on Android emulator but the screen refresh rate is too slow, as it will send the wrong message to the audience that the app is slow. (Or there is a way to increase the screen refresh rate for emulator?) Furthermore the emulator doesn't support multitouch. (Or am I wrong?)
Not sure if anyone
You do not have many options.
You can use Droid#Screen, but the refresh rate on it is maybe 6fps. I am not aware of any other software projector that is faster.
You failed to mention the "specific device" that you are using, so I cannot comment on whether it has TV-out capability. The HTC DROID Incredible and the Samsung Galaxy S series support composite output -- I use the DROID Incredible for this purpose a fair bit. Most of the devices that have HDMI output only support it for certain built-in apps, such as the video player.
You can rent or purchase a device projector, like an ELMO. These are fairly expensive pieces of equipment purchased new, though I see a handful of used ones on eBay at interesting prices (though watch out -- many seem to lack the AC adapter).
If you can delay the demo several months, you may be able to use a Google TV.
And that's about it, AFAIK.
Or there is a way to increase the screen refresh rate for emulator?
Get a faster computer.
Furthermore the emulator doesn't support multitouch. (Or am I wrong?)
I am not aware of a way to simulate multitouch with an emulator, though I have not gone looking for a solution there.
If you have an Galaxy S3 Android mobile phone, you can use Mobizen. It's free and the screen refresh rate is relatively good. You can control you mobile phone from you computer using your mouse and your keyboard. It's working using USB, 3G or Wifi connection.
I have used this Android screencast tool: http://code.google.com/p/androidscreencast/ in past demos, but again the downside is the relatively slow refresh rate.
If you have a rooted device, you could try Droid VNC Server (it's on the market). The refresh rate isn't too bad, but I certainly wouldn't want to demo full motion video or an arcade game on it.
You could also get a webcam, rig it up with a tripod. Something like this. Downside is your hands will be in the way, maybe issues with lighting and/or focus. Upside is a decent refresh rate.
I am using the code available here VideoView Example. This code runs properly on Android emulator 1.6 but not on 2.1.
In 2.1 it only plays the audio and not video. I have gone through several other threads where this issue has been mentioned. I will like to know whether this problem is limited to emulator only or the devices also have the same problem.

Emulators will have great difficulty playing back video, due to speed. The emulator does not have hardware acceleration -- combine that with converting ARM opcodes to x86 on the fly, and the emulator cannot keep up. I have a quad-core 2.6GHz desktop, and I can only occasionally get the emulator to play back video.
IMHO, to work with video, you need a device.
Try it in real android device,because emulator can not play video
