Various outdated versions of Android are available for our boards. Since Android depends on Vendor SDKs, they’re usually not supported or upgraded over time. We do not recommend using Android as the building block of anything. These images should be used for testing and experimentation only. There’s is little to no support for any issue you will have. The Android SDKs used to build the images are only provided under NDA by the SoC vendors and even then not supported very well if at all.
