DESCRIPTION
Android SDK brings with itself the two most important tools needed for tweaking your Android phone, ADB (Android Debug Bridge) and Fastboot
Why do we need them? ADB and fastboot helps us install a custom recovery, which allows us to root our Android devices, install custom ROMs and perform many other system tweaks which are not otherwise possible.
Here are the step-by-instructions to set up ADB / Fastboot on your computer. Follow the steps carefully and make sure you read the tutorial once before actually performing it.
1. Download and Install Java Platform (JDK) from [Java SE Software Development Kit (SDK)] downloads. Once installed, proceed to the next step.
2. Download Android SDK ([android-sdk_r20.0.3-windows.zip]) from the Android Developers website. Preferably: Click on Other platforms and download the ZIP package file for Windows.
3. Extract the zip file anywhere in your computer. We extracted in D:\ drive. So now we have, D:\android-sdk-windows.
4. Open SDK Manager and wait till it loads (fetches) all the packages.
