8. Extract downloaded sdk-tools to AndroidSDK"
9. Open command prompt at "...\AndroidSDK\tools\bin"
10. Install platform-tools using the following command sdkmanager platform-tools

11. Install corresponding platform and build-tools for your mobile device.

    1. sdkmanager platforms;android-28 (Use sdkmanager --list to see all packages available).
