Android A to Z: What is the AOSP?
Monday 21st of May 2012
AOSP is a term you'll see used a lot -- here, as well as at other Android-centric sites on the Internet. I'll admit I'm guilty of using it and just expecting everyone to know what I'm talking about, and I shouldn't. To rectify that, at least a little bit, I'll try to explain what the AOSP is now so we're all on the same page.For some of us -- the nerdly types who build software -- the full name tells us what we need to know. AOSPstands for Android Open Source Project. The AOSP was designed and written by folks who had a vision that the world needed an open-source platform that exists for developers to easily build mobile applications. It wasn't designed to beat any other platform in market share, or to fight for user freedom from tyrannical CEOs -- it exists as a delivery mechanism for mobile apps -- like Google's mobile apps, or any of the 400,000+ in the Google Play store. Luckily, Google realized that using open-source software would ensure that this operating system/mobile application content delivery system is available for all, for free. And

Monday 26th of March 2012
Do you know what is the build number or the OS version of your Android device? If you do not know, it wouldn’t cost you anything if you spare some time to check what build number of the OS your device is running on. Knowing the build number of your OS will not be a piece of useless information that you can take for granted; it is helpful if you want to explore more about your OS. There are several ways to know the build number of your device and we will teach you the easiest way through this. Read more to know how to know the OS version or build number of your device.The development of the Android operating system has been a going on for several years now, starting from the first build to the most-craved-for Ice Cream Sandwich. The pace of the development just went faster and so many builds have been released. Many people want to know what OS version is running on their devices–out of curiosity. While many others want to know because the information is useful when installing apps, performing upgrades, or flashing customizations.Here’s a simple tutorial that will h
The Chromebook Pixel project: Chrome OS - Android Authority
Friday 08th of March 2013
Perhaps the most misunderstood part of a Chromebook is the operating system. Some don’t even think it’s a proper OS, while some swear by it. It definitely has limitations, but Chrome OS is probably a lot different than you’ve heard. Let’s get into some truths about Chrome OS, shall we?What Chrome OS isThe central part of any computer is the operating system, and Chrome OS is just not the typical offering. It has a lot going for it, which is rarely discussed. Chrome OS may be a fairly new concept, but it’s not a bad one by any means. In some cases, it may be just what you’re looking for.LightweightWhen your operating system is based on the browser, there’s not much you need on top of it. This is, perhaps, the central point of confusion about Chrome OS. Rather than design and build an entirely new OS to combat Microsoft or Apple, Google went a different route. With the world increasingly moving towards being online almost constantly, Chrome OS makes a lot of sense for many due to it being straightforward and effective for what they want to do.SecureChrome, be it
AOSP Build for a Specific Device Other than Nexus
Wednesday 15th of August 2012
Hi,I downloaded AOSP from http://source.android.com & follow the steps of building the system as mentioned. Got system.img and other img files in the building process of the code. Then I fastboot system img to my android htc desire s device. it installed successfully. But when device reboots, it gets stuck in htc logo. I also tried installing imgs in many different ways. nothing worked.As cyanogenmod & other designing companies have created a custom roms for htc desire, I would like to know how they have solved that issue.What can be the reason for this. Same code works fine in emulator. I saw that AOSP only works in Google nexus devices. For other devices, in order it to work properly need to have drivers (proprietary binaries). Is that true? If so how can I create my own custom rom by using AOSP?**Does this AOSP only nativly works in Nexsus devices? If so what is the use of it as open source?Really appreciate any positive reply on this.Thanks.
Howto build a booting CM10.1?
Sunday 07th of April 2013
Hi guys,Just to understand how the Android/CM buildprocess is working, I've tried to build a CM10.1 ROM with the official CM10.1 sources and gmarkall's CM10.1 device-files from https://github.com/A2109devs/android..._lenovo_a2109a...What I get is a not bootable system...(hangs on first Lenovo logo on screen)I changed the Kernel to Stock Lenovo 4.1.1 (3.1.10) through CWM and the device booted to CM10 Bootscreen. (I haven't tried to changed the libs)So my question is: what is to do to get a booting and (mostly) running CM10.1 (like superhansi's one)? And until now I can't get a booting Kernel with the new source, could you please tell me what I have to do to get a running kernel?Thanks a lot,awatch
Android 4.0 Ice Cream Sandwich Source Now Available - Coming to an Android Near you Soon! - Android Authority
Sunday 20th of November 2011
Great news everyone! As I write this, the Android Dev team is uploading the Ice Cream Sandwich (Android 4.0) source code. While they are saying that it’s a massive release, and it’s not currently finished, it should be completed very soon. Furthermore, this is the same release as what’s going to be on the Galaxy Nexus, which is Android. 4.0.1.According to the Android team:However since this is a large push, please be aware that it will take some time to complete. If you sync before it’s done, you’ll get an incomplete copy that you won’t be able to use, so please wait for us to give the all-clear before you sync. This is actually the source code for version 4.0.1 of Android, which is the specific version that will ship on the Galaxy Nexus, the first Android 4.0 device. In the source tree, you will find a device build target named “full_maguro” that you can use to build a system image for Galaxy Nexus. Build configurations for other devices will come later.It’s important to remember that this code is specific to the Galaxy Nexus, but you can

Google Nexus 7 morphed into ultimate in-car entertainment system
Monday 06th of August 2012
Lots of people have a love of both automobiles and a love of music. The two seem to go hand in hand. The popularity of the combination drives people to all sorts of attempts to build the ultimate car stereo system. In recent years, a new factor in the equation has emerged – the use of smartphones and tablets to serve as the nerve center for an in-car entertainment system. SonicElectronix recently completed a build for a Dodge RAM that incorporates a Google Nexus 7 tablet into the dash for this purpose.//SonicElectronix has connected the Nexus 7 tablet to an Audison bit one controller that drives the audio equipment. By using the Nexus 7 tablet, you can use the Android interface and apps like Google Music to navigate to the music you want to hear with a few finger flicks on the screen. If streaming music is more to your liking than what is in your library, you can access apps like Pandora or Spotify. More than music is available by using a tablet like the Nexus 7 for the interface. The Google Maps app can be used as a navigation unit. Passengers can use the tablet to watch video

What do I "lose" with straight Android?
Saturday 12th of October 2013
I'm thinking of a Nexus for my next phone, but am not sure where plain Android ends and mfr/carrier customizations begin on the phones I've been using. I had an unlocked HTC Desire (Android 2.3) and now an AT&T Galaxy S2 (4.x), but have never been exactly sure what functionality is custom vs. standard Android.For example, a lot of the newer phones have some tricked-out camera options that I'm sure are missing in the basic release. Also, aren't there some hardware features that the mfrs build in that would not be recognized by a vanilla Android build?I have no interest in rooting my phone and flashing new system images, etc. But I do want to be able to quickly upgrade to new Android versions, and as a developer I'd like to be able to verify that my product works on a phone with no vendor-specific add-ons getting in the way. Will I feel that I've lost anything by going this route?
