Geeksphone Revolution añade otro sistema operativo a su repertorio, y reduce su precio #teléfono #noticias

El Geeksphone Revolution es uno de los pocos smartphones que soporta oficialmente más de un sistema operativo, pues aquellos que estuviesen interesados están de enhorabuena, ya que acaba de recibir una reducción de precios y el apoyo de CyanogenMod.

Este smartphone fue lanzado a principios de 2014, y su peculiaridad es que tenía soporte para Android y para Boot2Gecko, un dispositivo que prometía…

O B2G( Boot to Gecko ), é uma plataforma para dispositivos moveis que esta sendo desenvolvida pela mozilla. Com o intuito de ser aberta, e utilizando padrões web para construir os aplicativos para essa plataforma. As tecnologias seriam HTML5, CSS3 e Javascript.

A metas deste projeto é construir uma plataforma para dispositivos moveis totalmente baseada na tecnologias abertas. E que uma plataforma não deve ter um dono. E utilizar os conhecimentos existentes para a construção de aplicações web nessa plataforma.

A turning point in an open source mobile OS?

NEW ORLEANS — Mozilla is most famous for its desktop software, so seeing the non-profit, open-source-oriented company at a trade show for the wireless industry initially seems odd, even dissonant. But the developer behind the Firefox web browser and Thunderbird e-mail client is branching out into a smartphone operating system of all things, so its presence at the CTIA wireless show in New Orleans is all but de rigueur. “The mobile space is different than the desktop web,” Todd Simpson, Mozilla’s chief of innovation, told Wired at CTIA. “We can’t rely on word of mouth to get us onto smartphones and into retail stores with the level of success it had for us on the desktop.” With that in mind, Simpson and other Mozilla honchos attended their first CTIA convention, showing off phones running their operating system project, Boot2Gecko, or B2G. I caught up with Simpson, and tried out B2G running on four different Samsung Galaxy S II handsets. While the software is still in its early stages, it did look very promising.‪ ‬”The interest we’ve seen from operators so far is because we’re offering the open web on a smartphone, and anyone can grab it and use it however they’d like.” –Todd Simpson‪ ‬The B2G operating system, its user interface, and all the apps it runs are built entirely using modern web standards, such as HTML5 and JavaScript. On the backend of the OS, everything runs on Gecko, the HTML rendering engine Mozilla uses for its Firefox browser — hence the somewhat clunky, consumer-unfriendly name, Boot2Gecko. Simpson promised that the web-based OS and all the apps it runs will eventually match the functionality and performance of what we see in Google’s Android OS, Apple’s iOS and Microsoft’s Windows Phone platform. It’s an ambitious goal, but from what I saw, its didn’t seem far-fetched. At this point, B2G’s user interface consists of a few home screens’ worth of apps, each of which can be launched by tapping a rectangular icon. The apps may be web-based, but launched blazingly fast because most were cached onto the phones. Thanks to the caching scheme, B2G phones will still work when a network signal is out of reach. So far, Mozilla is only showing off the most basic apps. There’s a phone dialer for making calls, a web browser (of course), a camera app, a gallery app for checking out the photos you’ve shot, a video player, and a calculator app. B2G also runs a few games, including the iOS and Android hit Cut The Rope. An app called CrystalSkull demoed Boot2Gecko’s ability to handle complicated 3D graphics — you manipulate the motion of a clear, floating skull with touches and swipes. CrystalSkull, and every other app I tried, responded exactly as you’d expect from a smartphone. Pinching and zooming photos, surfing the web, playing games, and even placing an actual phone call all worked with no touchscreen lag or performance issues. In all, my 30 minutes with the B2G phones left me feeling like I had been field-testing a perfectly able set of smartphones. But, again, Boot2Gecko is in its early stages. There’s no centralized app store, no place to buy music and movies, and the camera app can’t yet shoot video. What is clear, however, is that Mozilla is making progress at a surprisingly fast pace. Could HTML5-based apps spell the end for relatively closed app platforms like iOS and even Android? Only time will tell. But if nothing else, B2G proves that basic, baseline app-like functionality can be executed in HTML5 and JavaScript. Simpson wouldn’t say which hardware makers are interested in using Boot2Gecko in the U.S. market, though rumors have floated LG as a possible OEM partner. Demoing the OS on Samsung Galaxy S II handsets wasn’t a plug for Samsung, Simpson said. “We’re using Samsung phones because they’re good phones and we had them around,” Simpson said. “We’ve had Boot2Gecko running on a bunch of different phones from different companies so far.” Anyone with a GitHub account can download a build of the OS and load it to a touchscreen handset to try the software out for themselves, he noted. Telefonica is hoping to launch a smartphone running Boot2Gecko in Brazil sometime early next year, and T-Mobile’s parent company Deutsche Telekom is interested in offering B2G phones as well, Simpson said. Oh, and about the name: When the OS eventually launches, it won’t be called Boot2Gecko, Simpson said. Like the Firefox browser, B2G is a completely open-source project, with Mozilla engineers working alongside any coder who’d like to contribute across the web. The open source approach will allow for infinite customization possibilities, Simpson said, complete with downloadable user interface themes (later on, down the road) and the option for hardware manufacturers to fork the software into their own operating systems. “Our goal is to keep Boot2Gecko as open as possible,” he said. “The interest we’ve seen from operators so far is because we’re offering the open web on a smartphone, and anyone can grab it and use it however they’d like. No other operating system is really offering that at this point.” By Nathan Olivarez-Giles

This is my Samsung Galaxy S II running my orange theme on BootToGecko.

BootToGecko is NOT CONSUMER READY!

It's a pre-pre-pre alpha system, much like the iPhone would've been back in 2003, when the definition of 'smartphone' was a PocketPC.

BootToGecko Features

Here's what it does do at the moment:

Make calls

Send texts

Browse the web

Install a selection of Mozilla Open WebApps

And now, what it DOESN'T do:

App notifications (e.g. Mail, Twitter)

Stay stable (occasional crashes send it into stock BootToGecko mode)

Play your music/video (SD card support is still being tested)

Build Environment Requirements

I'm currently using a Dell XPS 15 (L502X) which dual-boots Ubuntu 11.10 (x64) and Windows 7 (x64) and is, overall, a pretty sweet machine.

I'd suggest atleast 4GB RAM, plenty of storage space, and a strong internet connection.

The Steps I Took

If there's a problem in the steps (I might've forgotten something) or a step simply doesn't make sense, please leave a comment and I'll get back to you ASAP!

Install Ubuntu 64-bit I created an ext2 partition for the Ubuntu installation, and an 8GB swap partition as recommended. This isn't required, however, and you can simply install inside Windows for an easier process.

Boot into Ubuntu You won't be seeing Windows for some time, so say your goodbyes.

Install Mozilla's Build Environment packages Just copy these commands into a Terminal and press Enter. Press 'Y' when prompted and it should take care of the rest.

sudo apt-get build-dep firefox sudo apt-get install git mercurial libasound2-dev libcurl4-openssl-dev libnotify-dev libxt-dev libiw-dev mesa-common-dev autoconf2.13 sudo apt-get install ia32-libs gcc-multilib g++-multilib bison flex gperf lib32z-dev lib32ncurses5-dev lib32ncursesw5-dev sudo apt-get install libidl-dev lib32gomp1 autoconf2.13 ccache libx11-dev lib32readline-gplv2-dev

Install OpenJDK

sudo apt-get install openjdk-7-jre

From the Software Centre, it's easy enough to find. I used version 6 rather than 7 since it's been around longer. Mozilla recommend 7, so you can use the above command to get that version, if you want.

Download Android SDK From the Android Developers' page, download the .tar.gz file, extract it, and copy the 'android-sdk-linux' folder to your /home directory (mine's called '/nikhil') I've never gotten the hang of adding PATH variables, but if you do, go right ahead and perform your ./bashrc magic. I have a workaround that'll be explained later.

Edit Android config files to allow your SGS II to interact with Ubuntu

sudo gedit /etc/udev/rules.d/51-android.rules

This will open an empty file in Ubuntu's default text editor. Add the following line:

SUBSYSTEM=="usb", ATTR{idVendor}=="04e8", MODE="0666", GROUP="plugdev"

Save and close the file. Now run the following command to make the file readable.

sudo chmod a+r /etc/udev/rules.d/51-android.rules

Install Heimdall Run the .deb file from https://github.com/downloads/Benjamin-Dobell/Heimdall/heimdall_1.3.1_amd64.deb It's a program that easily interfaces between Ubuntu and the Galaxy S II. It's a quick download from the website, and an easy install since it's a .deb file.

Backup your Galaxy S II My Galaxy S II has been rooted since day one, and it's time for you to do the same. ClockWorkMod's ROM Manager is a fantastic tool that eases the backup/restore process, and you should definitely get it. Once you have it, backup your phone using the CWM app from Google Play, or reboot into Recovery Mode and make a backup there. Then, mount the SGSII as a drive via USB and copy over all the files from your phone.

Install Git

sudo apt-get install git

Easy to find in the Ubuntu Software Centre, it's a one-click process to install.

Create a new 'BootToGecko' build folder This is where everything will be done. I put mine in '/nikhil/B2G' but anywhere is fine.

Install 'Open in Terminal' to drastically improve your productivity

sudo apt-get install nautilus-open-terminal nautilus -q

This feature used to be present in older versions of Ubuntu, but seems to have been removed by default, for whatever reason. It lets you open the current folder in Terminal, saving you having to manually change directory by typing.

Change working directory to the BootToGecko directory Navigate to your BootToGecko folder, right click open space and select 'Open in Terminal'. This opens a command prompt and you enter all the subsequent commands here.

Use Git to 'Clone' the BootToGecko repository from GitHub

git clone https://github.com/andreasgal/B2G.git

This takes a few minutes, after which you can open the /BootToGecko folder and see it filled with stuff.

Use the 'make sync' command to actually build BootToGecko; this takes AGES!

make sync

TIME TO BREW A GOOD CUP OF COFFEE! From what I can tell, this command downloads the majority of BootToGecko files and then compiles them. My internet connection died a few times during this step; this meant I had to stop the command using CTRL+C and then run 'make sync' again. The good thing is, it only restarts the interrupted file, so you only lose a few hundred megabytes, tops.

Plug in the phone and run the Galaxy S II specific commands

export ANDROIDFS_DIR=sgs2-android make config-galaxy-s2

This pulls a lot of files from your phone, so that a suitable version of BootToGecko is built. I had a tough time with this step, since it didn't recognize my firmware version. Eventually, an Ubuntu restart and a phone restart solved the problem. If it still doesn't work, restore your phone to the original stock firmware and try again.

Build the kernel

make kernel

Takes a few minutes, just be patient.

Reboot the Galaxy S II into 'Download Mode'

adb reboot download

This gets the phone ready for any kernel changes. An android image should be displayed, along with some text saying 'Download Mode'.

Flash the BootToGecko kernel using Heimdall

heimdall flash --kernel boot/kernel-android-galaxy-s2/arch/arm/boot/zImage

A one-line command that should do all the work for you. Watch the phone display for a progressbar which should fill up quickly.

Reboot the Galaxy S II into 'Recovery Mode'

adb reboot recovery

This should reboot into ClockWorkMod, or the equivalent Recovery manager.

Build and flash the base OS

make gonk

'Gonk' is the codename for the base Operating System which BootToGecko is built upon. On top on Gonk is 'Gaia', the actual system that manages what you see on the display, such as the lock-screen/home-screens etc.

Finally, build and flash the rest of BootToGecko

make flash

Be patient, and make sure the phone is connected to the computer while this command runs. Once it finishes, it will automatically reboot the phone into Recovery mode and install the final bits of BootToGecko.

POTENTIAL PROBLEMS

adb commands don't work, 'adb could not be found' This is easily fixed. Go to the 'android-sdk-linux/platform-tools' folder and copy the 'adb' file. Paste it into the BootToGecko folder. Now, whenever you need to run an adb command, add a './' to the front. The './' denotes that adb is located in the current folder, and thus links to the file you just copied.

A '500 - Server error' page is displayed This means that BootToGecko cannot access the 'Gaia' interface, either on the phone or online. For me, this was due to an error while building BootToGecko's 'Gaia' front-end.

make install-gaia

This command re-builds and installs the Gaia interface. Read the output to see if any error has occurred. If there is an error, it means the command was unable to find 'adb'. Fix this problem by either adding adb to Ubuntu's PATH variables, or editing the 'Makefile' at '/B2G/gaia' and changing line 14 to:

ADB?=./adb

And copying the 'adb' file to the '/B2G/gaia' folder as well. This means Gaia will now build using the copy of adb stored in its own folder.

Final notes

Don't expect to use BootToGecko as an everyday OS. It's just an enthusiast's toy for now, but I'm expecting ridiculous amounts of development within the next 6 months.

Once the BootToGecko phones land in the market, expect high quality releases that will easily compete with Windows Phone, Android and iOS.

There are a lots of mobile OSes today iOS, Android, WP7, webOS, etc. Some are open sourced many are closed. Most of them though expose native APIs using which app developers create apps for these platform either using predefined languages or tweaked versions of C++, Javascript, etc. There is also an effort by quite a number of frameworks such as PhoneGap and Appcelerator that allows developers to build HTML5 applications and run them on these individual OSes. More like build one and deploy on all. But it is not as simple as that as what can be accomplished via Java on Android is not the same as Javascript on Android via PhoneGap.

Mozilla is entering the mobile space with is own OS called the Boot2Gecko. The aim of the project is to build the entire UI and app stack using HTML, JavaScript and CSS standards. The entire project is built out in the open right from the start. The source code is available for everybody to view and test. In the run up to this project Mozilla launched the WebAPI project that aim to expose consistent JavaScript APIs across web browsers, operating systems and devices. Mozilla is also working to standardize these APIs. What this would mean is that B2G can run as well on a browser as well as it planned for a mobile device. The core objective of the B2G project is to enable browser based mobile apps built using HTML and JavaScript to perform all those functionalities that apps built using native frameworks do. 

The UI of B2G is called Gaia and is a collection of web apps. I downloaded the code from GitHub. Since the entire stack is built using HTML, CSS and JavaScript this can be run on the browser. I opened the homescreen.html and was able to navigate to most of the other screens. Most of the clicks and swipes are available to be tested on the browser right now. In fact Penguin Pop and Tower Jelly was available to play as well. It If you happen to posses a Samsung GSII or its variants then you can run the current version of the OS on it. Check this for instructions and this for a demo.

This is a paradigm shift in the way mobile OSes are today. Android is open source but not from ground up. webOS will be soon but it uses it own set of frameworks. What B2G aims is to essentially take jquery and build apps or run many of the existing apps available on the Mozilla store or any of the other stores that feature HTML5 apps.
