Google has released the first developer preview for Android O, its eighth operating system to follow the lettered naming convention that will likely see a full release later in 2017. While there’s not a whole lot that’s new, at least in the premiere snippet of software, you’re probably wondering how you can get it on your device. First off, you’ll need one of the following devices: Google Pixel, Google Pixel XL, Google Pixel C, Nexus 5X, Nexus 6P. If you own the Nexus Player, you can follow along, too. Just make sure that you can plug it into your television or a monitor to keep up with the steps. Next, you’ll need a little bit of time and patience to install it. Be warned, Android O is unfinished and therefore buggy software currently, so it’s best to load it onto a device that isn’t your daily driver. It’s also worth noting that Google hasn’t enabled Android Beta support for O just yet, so the only way to get the new software is by doing things the hard way. However, future previews will likely be delivered via over the air (OTA) update. Ready to get started? Let’s do this. Back up your device Digging into the back-end of your Android device presents the risk of unintentionally wiping your data. And since we’re flashing the phone, unlocking the bootloader will wipe your device. Thus, you’ll want to make sure you have your things backed up. Thankfully, it’s easy enough to back up your Android smartphone. Head to “Settings” then navigated to “Backup & Reset”. If you have a computer handy, copying over photos from the DCIM folder is a simple drag-and-drop affair. But it’s just as easy by backing up your photos and videos via Google Photos. Become a developer It’s now time to become a developer and thankfully, your phone won’t notice if you’re lying. Navigate to the “about phone” section and scroll down to where the “build number” is listed. Click this box seven times and you will magically “become a developer”. With these powers bestowed, a new option called “developer options” pops up on the previous menu. Click into that. Make sure that both “OEM unlocking” and “USB debugging” are both set to the “on” position. This will allow both the bootloader to be unlocked with a simple command (detailed below) and for your computer to be able to send files to your device. Once you’re all set, we’re ready to download the system image. Downloading Android O Now, you’ll need to download the image that’s made for your device. Google has made it easy and listed each of the supported devices next to their corresponding preview images. Click and the download will begin. The file size is well over 1GB, so to keep busy during the download, head to the next step. Download 15 seconds ADB installer This lightweight application installs all of the necessary files to allow your PC to communicate with your phone and send over the new Android O software. Download the program here and run the software. A window will appear asking if you want to install ADB and Fastboot. Type Y on the keyboard to agree. Press Y again when asked to Install ADB system-wide and if you want to install device drivers. A new window will open to start installing the drivers. Allow this, then click restart now to reboot your PC. The program will now be installed to C:\adb (if C:\ is your default hard drive). Now, it’s time to plug your phone into your computer (if it isn't already). Get your system image files in order Once you download the Android O image for your device, you’ll need to shift it around to a different location on your hard drive. Right click it and unzip the .zip file using a program like 7Zip and set it to extract in C:/adb, if that’s your default drive letter. If you’re confused, refer to the image above to see what your C:/adb folder should look like at this point. Flash Android O to your device The fun begins. Power down your phone and ensure that it’s plugged into your computer. Now, you need to start it in fastboot mode – to do this on the Nexus 6P, press and hold down the Volume Down and Power buttons on the handset from the off state. Same goes for the Nexus 5X, Google Pixel, Google Pixel XL and Google Pixel C. Once your device has booted in fastboot mode, open up the folder on your PC where you extracted the Android O image to. Click into the folder until you find a file called flash-all.bat. Double click this to begin installing the new software onto your device. (Refer to the image above if you're confused at this point) The next and final step: be patient! If all goes well, the process should take about five minutes. Unfortunately, there’s no progress bar, so you’ll just have to trust that things are going well. You can watch the process unfold in the command prompt menu. If you’re experiencing an error due to a locked bootloader, you’ll need to unlock it.In the C:/adb folder, hold shift and right click in empty space. Select “open command window here”. Now, type the following commands. fastboot devices The above command will display your phone’s serial number. A good sign that it’s communicating well with your computer. fastboot flashing unlock This will unlock your bootloader and wipe everything on your phone in the process. To re-lock the bootloader once Android O is installed, simply enter the following command. fastboot flashing lock Keep in mind that if you want to revert to Android Nougat, or if you see yourself wanting to flash in the future, you may want to leave it unlocked so that you don’t have to wipe your device going forward. However, an unlocked bootloader means that Android won’t ask for your PIN or fingerprint for authentication upon boot. So if your phone is stolen, the thief will be able to wipe it. You did it! Congratulations on installing Android O. Once you've completed the steps above, your device should now reboot and be running the latest, but not yet greatest software from Google. It has more than a few kinks to iron out before it can claim that title. Source
CrAKeN posted a topic in Mobile NewsOfficial Android O logo Today, Google launched the very first Android O Developer Preview, making the version available for download. The release is aimed at developers and Google did mention that it’s not intended for daily or consumer use. It’s worth mentioning that Android O Developer Preview packs lots of bugs and various stability issues, as expected. The new version can be installed on Google Pixel, Pixel XL, Pixel C, Nexus 6P, Nexus 5X and Nexus Player. Google made the Developer Preview system images available, together with Release Notes that contain additional information on the new Android OS version. Google did mention that some apps may not function properly and that battery life may be regressed for screen-on and screen-off use cases. A number of new features were announced Google detailed several new features that developers will find in the first Android O preview. Therefore, this version comes with background limits, which will allow users to improve their phone’s battery life and the device’s interactive performance. As expected, Google brought notification channels, which are new “app-defined categories for notification content”. It will give developers the option to control different kinds of notifications and users, the ability to block or change the behavior of each channel individually. New visuals and grouping tools were also added. Moreover, this version introduces new autofill APIs for apps to store and secure data per user request. Picture-in-picture display was made available on phones and tablets so users can work on multiple apps at the same time. Google also added a new app overlay window and multi-display support for launching an activity on a remote display. Adaptive icons in Android O Another change is adaptive icons that are displayed in different shapes, based on user preference. Connectivity options for Bluetooth and WiFi were also added, together with wide-gamut color for app developers. This release is mainly targeted at developers, while a stable version of Android O is expected to be announced later this year, after a number of developer previews are released. Source
CrAKeN posted a topic in Mobile NewsGoogle I/O Google is said to offer a first glimpse at Android O during the Google I/O conference, set to take place in May. Until then, new information about the upcoming OS version continues to surface online, the latest referring to changes regarding notifications. Apparently, Google intends to bring lots of changes to notifications in Android O, including app icon badges for notifications. This would mean that each notification would carry the app icon, and users would be able to get a quick glance at how many notifications they have for any given app simply by looking at the home screen. In addition, 9to5Google stated that Android O could come with a completely redesigned notification system, but that remains to be seen. Google might also include a picture-in-picture mode just like on Android TV. Moreover, Google might be working on a smart text selection floating toolbar with Assistant integration. The feature would automatically copy relevant information from apps and surface it when needed. The “Copy Less” feature was mentioned in an earlier report, stating that it would include integration with Google Assistant. Restricted background activities from apps and dynamically changing icons Google might also bring the restricted background activities from apps feature to Android O. The tool is currently found in Chrome 57 and it allows users to reduce power consumption of background tabs, so that battery life would be optimized. The stricter throttling tool in Chrome 57 can result in 25% less power consumption. Dynamically changing icons is another feature revealed in the report, a feature that is currently found in the Pixel Launcher for Google Pixel smartphones. Furthermore, Google may intend to bring lots of improvements to MediaRecorder API, which allows apps to capture audio and video in order to save data to persistent storage. Moreover, improvements could also be brought to enterprise features and audio latency. Take this information with a grain of salt for now, and we’ll just have to wait and see what Google has in store for Android O. When it comes to the name of the upcoming version, some have hinted towards Android Oreo, but it’s simply too early to say for sure. Source
