Ever wanted to download adb or fastboot without having to download the whole of Android Studio?

Google released adb/fastboot binaries:

• SDK Platform-Tools for Windows
• SDK Platform-Tools for Mac
• SDK Platform-Tools for Linux

The links on that page will always return the adb/fastboot binaries currently shipping with Android Studio. No need to guess what the current version is, or update your own links: just follow these and get the latest binaries, direct from the source.
