OS

Android

What Android verison running on ROCK Pi? Can I install Google Play apps?

Currently ROCK Pi 4 have two android 7.1 based images, Android TV like image and Android tablet interface image. Both support Google Play Store. The Android tablet like version supports touchscreen and Camera and HDMI. The Android TV version supports HDMI. Newer Android 9 is working in progress now.

Can I install Android on USB 3 or M.2 SSD?

Currently Android is running on eMMC only. We are working on running on microSD card now. Running on USB3 or NVMe SSD is a little bit trouble some since the CPU can not load USB/NVME directly to boot. So we must put an external bootloader in SPI flash or eMMC or microSD card to loader the image in USB 3 or NVMe SSD. ROCK Pi 4 has reserved SPI flash on board but currently not mounted by default shipping. We are still considering it since if the program in SPI flash is corrupted, it will be trouble some for user since the SPI flash is not removable. We will work on Android running on USB 3 or NVMe SSD.
