Aug 21, 2017  Owners of either one of those devices are now able to download the first Android 8.0 Oreo system image for their smartphone and manually flash it onto the device. Note that this method is. While there might not be any Samsung system images to download and install on the Android Studio emulator, there is another option. Samsung has something called Remote Test Lab, which lets you access and control a real Samsung device online.You have to join the Samsung Developers programme, and then you can use these test devices.

The Android Developer Challenge is back! Submit your idea before December 2.

A Generic System Image (GSI) is a pure Android implementation with unmodified Android Open Source Project (AOSP) code, runnable on a variety of Android devices.

Figure 1. GSI support across devices.

Starting with Android 9 (API level 28), Generic System Images (GSIs) are available to app developers throughout the full Android release cycle. You, as an app developer, can install and run the latest Android GSIs on a variety of existing Android devices, and in different Android OS release stages including Preview and Beta phases, to perform app testing! In this way, your app gets broader test coverage, starting at an much earlier time than before:

  • More test coverage on real devices
  • More time to fix app compatibility issues
  • More opportunities to fix non-compatible issues in Android OS reported by app developers

Note: You would install a later GSI version than the version of Android currently installed on a device.

The GSI project helps improve the Android ecosystem by providing more ways to improve app and OS quality before the next release of the OS. The project is also open-sourced.

GSI includes core system functionalities in all devices running Android 9 and above; in other words, GSI does not include device manufacturers's customizations. You might encounter behavioral differences in the following situations:

  • Interactions that involve the UI.
  • Workflows that request newer hardware features.

Check device compliance

GSI works only on devices with the following characteristics:

  • Bootloader is unlocked.
  • Fully Treble-compliant.
  • Launched with Android 9 (API level 28) or higher. Devices upgraded to Android 9 from an earlier version may or may not support GSI.

Warning: Attempting to flash GSI to a non-compliant device couldresult in your device becoming non-bootable. Always confirm that your device is compliant before flashing, and follow the installation steps provided by your device's manufacturer. GSI doesn't support rollback. You will need a recovery method and original system ROM to revert to the original system.

To determine whether your device can use GSI and which GSI OS version you should install, do the following:

  1. Check for Treble support by running the following command:

    If the response is false, the device isn't compatible with GSI and you shouldn't continue. If the response is true, continue to the next step.

  2. Check for cross-version support by running the following command:

    Note: Depending on your platform, the configuration file in the preceding command may or may not have a version identifier in it.

    In the output, look in the section [vendor] for namespace.default.isolated.

    If the value for that attribute is true, then the device fully supports Vendor Native Development Kit (VNDK) and can use any GSI operating system (OS) version newer than the on device OS version. Choose the latest GSI OS version available.

    If the value for the attribute is false, then the device isn't fully VNDK-compliant, and the device can use only the GSI for the same on-device OS version. For example, an Android 9 (API version 28) device that isn't VNDK-compliant can load only an Android 9 GSI image.

  3. The GSI CPU architecture type must match the device’s CPU architecture. To find the right CPU architecture for the GSI image, run the following command:

    Use the output to determine which GSI image to use when flashing your device. For example, on a Pixel 3, the output would indicate that the CPU architecture is arm64-v8a, so you would use the arm64 type of GSI.

Download GSI images

These versions of GSIs here are not to be used by OEMs to run and submit compliance tests. OEMs should continue to refer to their existing communication channels, such as their Technical Account Managers for compliance test related activities.

There are a few ways to get GSIs, depending on your development needs:

  • For Android 10 GSI images, download from the GSI release page.
  • For Android 9 GSI source code, download from AOSP and build your GSI images.
  • For pre-built GSI images without GMS applications, download from the AOSP CI site.

Install GSI images

Note: If your device has adopted Android Verified Boot (AVB), download and flash the following image to disable AVB before flashing a GSI: vbmeta.img

Installing GSI is device-dependent. Refer to your device's manufacturer for the exact tools and procedures. For Pixel 3 and newer devices, there are several ways to install:

  • Manually flashing GSI images — see Flashing GSIs
  • Using Dynamic System Update (DSU) for devices that already run Android 10 — see the Dynamic System Update site
  • Android os image download

    Updated: Google released the official build of Android 10 for the Google Pixel series devices. The latest official Android 10 GSI builds (generic system images) are now available for download officially from Google servers. Earlier, we posted about the Android Q GSI beta builds available for downloads directly from Google’s servers. Here are the Android 10 GSI builds. We also have the custom Android 10 GSI by Erfan Abdi for One UI, Oxygen OS, MIUI, Zen UI, Flyme OS, Hydrogen OS, NubiaUI, Moto, Candy ROM, Xpieria, Pixel, ZUI, and more.

    Original: Android Q is going to be the next version of the most popular mobile operating system in the world. This is the tenth iterations of Android OS and it comes packed with many new features. These features include a native system wide dark mode or night mode, advanced or complete control over Android permissions using permission usage section, possible accent and font options, and time to read feature. So download Android Q GSI right now!

    With the new permissions usage section under Privacy tab in settings app, you can control all the permissions that certain apps are using. Moreover, you can monitor the permission used by a certain app in real time right at the status bar. The dark mode can be activated from the Developer Options and can also trigger some apps to get native dark mode feature. Most importantly, there is a new option in the Accessibility settings called Time to read where you can control the time of heads up notifications that appear on the screen.

    There is also a new Desktop mode under Developer Settings that we may see more about once the Android beta program kicks in. Maybe something like Samsung Dex? Android Q may also support accent colors or fonts similar to Oxygen OS, and support for native face unlock feature for all.

    The Android Q beta program that will start likely in mid-March and stable builds will be available in 2019 itself. Moreover, here we have the early builds of the Android Q GSI (Generic System Image) even before the Android 10 Developer Preview builds. You can flash the GSI images onto your Project Treble supported Android phones.
