FrostWire for Android has 2 versions: Plus and Basic. The Plus version has all the functionality of the Basic one + ability to download and preview files from YouTube and SoundCloud.
To download the FrostWire Plus:
1. Allow Apps from outside of Google Play. Tap on Settings -> Security, and check the box next to 'Unknown Sources'. Proceed with the installation.
3. Download the FrostWire PLUS .apk.
4. Tap on the .apk file from notifications after the download is complete or find it using any File Explorer (we like File Commander) - it's usually in the Downloads folder.
5. Follow prompts in the installer.
NOTICE: IF YOU UPDATE YOUR FROSTWIRE, NO BACK-UPS ARE NECESSARY
If you uninstall the version you have and then do a fresh installation, you have to back up all your SD Card downloads or they will be deleted by Android (Learn More)
Google Chrome does not open .apks
We recommend you download the FrostWire Plus apk using Firefox, as the built-in Chrome web browser will only download the installer, but it will refuse to open it (a way for Google to force people to use the Play Store for installing apps)
If you don't want to install Firefox on your device, you can always open the FrostWire Plus installer downloaded with Chrome using a file explorer like File Commander, but any similar one will surely open the .apk file as well.
Tap on Settings -> Security -> and check the box next to 'Unknown Sources'. Go back and continue with the installation.
