sdk semi-manual installation

[aryez91]

Hi guys, I didn't manage to install sdk as it was instructed. So I downloaded and extracted manually two files: commandlinetools-win-6609375_latest.zip into whatsdump-master\android-sdk\cmdline-tools

and platform-tools_r30.0.4-windows.zip into WhatsDump-master\android-sdk\platform-tools

and set appropriate environment paths for both folders.

It got me somewhat forward, but still couldn't proceed either to launching whatsdump (its says [ERROR] Cannot find WhatsDump AVD; install Android SDK and emulator packages with --install-sdk), and by running with the --install-sdk flag i get this:

[INFO] SDK tools directory already exists, skipping download & extraction...
[INFO] Updating SDK from manager...

    startupinfo)
WindowsError: [Error 2] The system cannot find the file specified

Any ideas how to proceed?
