There are four ways to install Android apps on a PlugOS device.

1. Install basic applications from the official app store built into the PlugOS device.
2. Use the shared folder feature to copy APK files from the host to the PlugOS device and then install them. This method is suitable for APKs not published online, such as internal company or organization apps.
3. On the PlugOS device, use the browser to visit websites that publish Android apps, download the APK, and install it.
4. On the PlugOS device, use the browser to search for and download third-party app stores, then browse and install apps from there.
