Hi
Can you confirm what resolutions are supported by the banana pi running Android?

I need to be able to output 800x480
I am guessing. How would you be connecting this to the Banana Pi? It has no VGA.

Same "roblem" here.
I got a 7" LCD with a native Resolution of 800x480, and the LVDS-Board has HDMI, VGA and two Composite Inputs. it also supports, or should i say it interpolates higher Resolutions like 1280x720, but it looks aweful.

It would be awesome, if we could set the Resolution by some simple editing the Android configuration, but you sound like it's some kind of impossible
And if its possible, i also would like to know how to,do this

getting pretty annoyed by the Android Banana Pi display screen...my display monitor is complaining best with 1280 x 1024 and the Android display is still "readable" but very messy and distorted image....what else can I meddle with to make the Android display on my HDMI monitor look better ? any help will be appreciated

You can modify the resolution by opening the image with DragonFace.
Then edit Android Configuration

Maybe try mucking around with those.
Also, remember you can go into Android Settings -> Display and change the output mode / resolution in there

Hi,

So if I want to output at a resolution of 1024x768, what I need to do is use these settings?

  1. [disp_init]
  2. disp_init_enable        = 1
  3. disp_mode               = 0

  4. screen0_output_type     = 4
  5. screen0_output_mode     = 4

  6. screen1_output_type     = 4
  7. screen1_output_mode     = 4
Copy the Code
Is that correct?

"screen_output_type = 4 " is for vga and the BPi doesn't have a vga output.
So I don't think that will work.

Similarly the "screen_output_mode = 4 " is for a vga resolution which again is not supported.

   Yeah, that's what I was afraid of. Although the kitkat image uses that mode and the output works fine, that's what puzzles me... I'll give it a try in a few days and I'll let you know.I've tried changing the resolution from the command line (su root am display-size 1024x768), but the pi refuses to use the whole screen when I do that.

If all fails, is there anything other than dragonface to edit those images?

Can the boot partirion be mounted in Ubuntu to edit boot scripts or anything like that?
