Done loading packages. Preparing to install archives Downloading Android SDK Platform-tools, revision 26.0.2 Download interrupted: Connection to https://dl.google.com refused Done. Nothing was installed. Preparing to install archives Downloading Android SDK Platform-tools, revision 26.0.2 Download finished with wrong checksum. Expected 98832431e339c82be1fe910a733a3782071200fd, got aa3ef6f18eff4b8f12dbdf980647a6ce6c2ebe8c. Done. Nothing was installed. 

Answer 1

I had to install it by myself.

1. Download link:
   https://developer.android.com/studio/releases/platform-tools.html
2. Select the zip file SDK Platform-Tools for Windows and extract it.
3. Move it into your android directory, in my case it was: C:\Users\Public\Documents\Embarcadero\Studio\19.0\CatalogRepository\AndroidSDK-2433_19.0.27659.1188.
4. Now you have the new directory: C:\Users\Public\Documents\Embarcadero\Studio\19.0\CatalogRepository\AndroidSDK-2433_19.0.27659.1188\platform-tools.
5. Run SDK Manager.exe again.

In my case, the error was gone. I had to install 4 packages first and then I had to install 3 packages after that. Now it run perfect.

Answer 2

You can just extract the archive the SDK Manager already downloaded:

1. Go to your android-sdk directory
2. Enter the 'temp' folder
3. Extract the 'platform-tools_r26.0.2-windows.zip' to the android-sdk root directory

But this makes the checksum pointless, it might be better to wait until it is fixed unless you need the new version now.
