Android SDK Platform-Tools is a component for the Android SDK. It includes tools that interface with the Android platform, such as adb, fastboot, and systrace. These tools are required for Android app development. They're also needed if you want to unlock your device bootloader and flash it with a new system image.
Although some new features in these tools are available only for recent versions of Android, the tools are backward compatible, so you need only one version of the SDK Platform-Tools
26.0.2 (October 2017)
Add support for Pixel 2 devices.
26.0.1 (September 2017)
Fixed fastboot problems on macOS 10.13 High Sierra (bug 64292422).
26.0.0 (June 2017)
Updated with the release of Android O final SDK (API level 26).
25.0.5 (April 24, 2017)
Fixed adb sideload of large updates on Windows, manifesting as "std::bad_alloc" (bug 37139736).
Fixed adb problems with some Windows firewalls, manifesting as "cannot open transport registration socketpair" (bug 37139725).
Both adb --version and fastboot --version now include the install path.
Changed adb to not resolve localhost to work around misconfigured VPN.
Changed adb to no longer reset USB devices on Linux, which could affect other attached USB devices.
25.0.4 (March 16, 2017)
Added experimental libusb support to Linux and Mac adb
To use the libusb backend, set the environment variable ADB_LIBUSB=true before launching a new adb server. The new adb host-features command will tell you whether or not you're using libusb.
To restart adb with libusb and check that it worked, use adb kill-server; ADB_LIBUSB=1 adb start-server; adb host-features. The output should include "libusb".
In this release, the old non-libusb implementation remains the default.
fastboot doesn't hang 2016 MacBook Pros anymore (bug 231129)
Fixed Systrace command line capture on Mac
25.0.3 (December 16, 2016)
Fixed fastboot bug causing Android Things devices to fail to flash
