Once that is done, set your `ANDROID_HOME` environment variable to point to where you just extracted your files. Once that is done, set `sdk.dir` in `./local.properties` file, pointing to where you just extracted your files.
If you'd rather choose where android caches its stuff, also set `ANDROID_SDK_HOME` and `ANDROID_USER_HOME` (note that, if equal to `ANDROID_HOME`, they seem to get ignored).

This is not enough: gradle will complain that no license was accepted. You need to navigate to your SDK folder, enter `./bin` directory and run `./sdkmanager --licenses`.

It's not super clear what `--licenses` will do, but it seems that it fetches the current licenses from Google servers and then asks you to accept them. Once that is done, a new folder `licenses` will be created in your SDK root, containing an unique identifier for each software which license you accepted.

The only really necessary license is the android-sdk one (not preview or arm or mips). Everything else can be rejected.
Once you downloaded the SDK and accepted Google licenses, try to build the project once: Gradle will download missing components (such as Platform Tools, Patch Applier, Android Emulator, SDK Tools, Build Tools, SDK platform).

### Failed to find target with hash string '...'
This error is weird and I have no idea why it happens. I think I solved it by manually redownloading the platform with sdkmanager: `$ANDROID_SDK_HOME/bin/sdkmanager "platforms;android-xx"`
