Google releases an Android 11 Developer Preview for its ADT-3 Android TV box
Late last year, Google announced Android 10 for Android TV and the new ADT-3 developer device to go along with it. The ADT devices are fully intended for developers and they’re guaranteed to receive updates and security patches from Google. Today, Google is announcing the Android 11 Developer Preview for the ADT-3 box.
The Android 11 Developer Preview for Android TV doesn’t include any visual updates or user-facing changes, but there’s a lot going on under the surface. It brings a bunch of privacy, performance, accessibility, and connectivity features. In addition, there are a number of new APIs that Android TV apps can now use.
We wrote about the new developer features in the first Android 11 Developer Preview back in February. There are a few that are especially important for Android TV devices. One of the most notable is low-latency video decoding, which allows apps to check and configure low-latency playback for a specific codec. This is very important for real-time streaming services like Stadia.
Another important feature pertaining to Android TV is HDMI low-latency mode. This allows apps to check for and request auto low latency mode (commonly known as “game mode”) on external displays and TVs. In this mode, the display or TV disables graphics post-processing in order to minimize latency.
We also discovered that Android 11 adds support for a bunch of new game controllers, which will be very handy for gaming with Android TV. Android 11 adds 84 new mappings for Xbox, Razer, Mad Catz, and more. A controller mapping is what allows Android to appropriately associate buttons to the correct KeyEvent. So if you tap the “A” button it will translate to the “A” KeyEvent in the game.
As mentioned, the Android 11 Developer Preview for Android TV is strictly intended for developers. The following image is for ADT-3 developer device only. All user data on the ADT-3 device will be wiped after flashing. Once the device has been flashed to Android 11, you will not be able to go back to the previous Android 10 build.
- Download the system image (link) and unzip the file.
- Plug in the ADT-3 developer kit for Android TV and enable Developer options.
- Run flash-all.sh in the unzipped folder to perform manual system image installation to the ADT-3 device.
The flash-all script uses fastboot and adb tools to upgrade the system. The latest version of fastboot is recommended; developers can find it in the Android SDK Platform-Tools package.
