Android Studio - manually install android-sdk

On Windows 10: Download the file from e.g.: Extract the zipped file. Copy (OR Cut, not recommended) the contents of the extracted folder e.g.: x86. Find the android-sdk folder. By default, it should be located at C:\Users\[YOUR USER NAME]\AppData\Local\Android\Sdk. Look for a folder named system-images. Create system-images if it doesn't exist. Depending on the file you downloaded, create subfolders within system-images. E.g.: system-images->android-27->google_apis. Paste within google_apis. Restart Android Studio and the system image should be selectable. Shout if you need any further assistance. source :
