Android with landscape mode on eDP display

Moderators: chensy, FATechsupport

If anyone is interested, I have built a custom Android OS that supports landscape display on the 7" eDP display with the Nano PC T4.

The source is hosted on GITLAB and if you follow the instructions in the Wiki to build Android, you can swap the download link with mine to get the updated code.

Please note that it has custom graphics for the boot logo etc so you will likely have to replace a few things if you want to change these.

The landscape support for the touch is hard coded as I have not found a fix for auto detection of the rotation so any attempt to use portrait with this build will not rotate the touch. I will find the fix for this and post it at some point. For my project I always run in landscape so this is not an issue for me.

Could you detail What changes have you made?
I didn't jot them all down as I was doing the work (I know, ny bad) but this is a list that I can remember.

Changes to support Landscape more for the boot animation and have the UI in landscape. Still an issue with the initial stage of the boot animation that I have not tracked down but as it doesn't affect the operation once the boot completes, I will live with it for now.

Change the boot animation

Included AmazeFileManager in the build

Removed a number of FriendlyArm test programmes

Added RIL for SIMCOM7600E modem. Still has an issue with messages over 160 characters and SIMCOM looking into this.

Removed the URL that is used to check for Internet presence as this was causing the PPP connection to fail. Needs alternative but works without.

If I can recall all the changes, I will document them here.
Wow! An amazing contribution! I will be checking it out!

Question: does this build have root access?

Seriously, thank you.

Let me know if you can compile it without errors. I have been able to clone it with another VM machine but cannot build it. I am trying to work out of this is a GITLAB upload issue or I am missing some files from the original source on my machine.
