    Can you upload rockchip to Android OS 12 image and release a version?
    I have ESP32 and Tinker Board 2S.

    I need to use Tinker Board's Uart as well, and I also need connection to ESP 32's Access Point
    To do this, Android OS Version must be 12 or higher. Also, rockchip must be included within the OS for use with the Tinker Board
    (Reference URL: https://github.com/TinkerBoard-Android/rockchip-android-manifest)

    Is it possible to distribute including a rock chip within Android OS 12 version in the near future?

    Hello everyone!
    I have a Tinker Board 2s and it also has a touchable LCD display.
    The products of display model are as follows
    >> 9.3inch Capacitive Touch Display, High Brightness, 1600×600, Optical Bonding Toughened Glass Panel, HDMI Interface, IPS | 9.3inch 1600x600 LCD (waveshare.com)

    The display and the Tinker Board are connected using HDMI only.
    And the os image on the Tinker Board is Android 12. (Tinker_Board_2-Android11-v2.0.8-20220503)
    First of all, the lcd display on the Tinker Board shows Android's screen well.
    However, the screen is streched a bit vertically.
    I,ve also tried the following ways to solve this problem myself.

    on the Tinker Board 2s :
           Setting > Display > HDMI > (SCREEN SETTING) HDMIA: Change Resolution

    But it didn't work....
    How can I change the resolution to a normal state where the vertical is not stretched?
    Or does Tinker Board not support the resolution of the display I use....?
    I would appreciate it if you could let me know the solution!

    Thank you in advance.

    hello @ChaJH, 

    1. i mean the tinker board android os version you're using (for example android 11 v.2.0.8), did you get the sources from here? TinkerBoard-Android/rockchip-android-manifest (github.com)

    2. the sample codes from this .zip does include libmraajava.so, would you like to give it a try? 

    The Sample codes of Mraa API for Tinker Board 2: Android-MraaDemo_tinkerboard2.zip

    thank you sir, @tooz!

    mraa works normally.

    Thank you very much.

    @tooz,  As you said, can I get it in that version and proceed with it?

    Like the image above.
    Can I download and use Tinker Board OS from the official site (https://tinker-board.asus.com/download-list.html?product=tinker-board-2s) )?

    Or, should I download it from the giturl you told me?

    The image above is Android Studio using mraa-2.2.0.aar.

    I need Uart control Tinker Board 2S.

    However, when you build an app through Tinkerboard using the mraa library, the app dies with the following error.

     

    [java.lang.UnsatisfiedLinkError: dlopen failed: library "libmraajava.so" not found]

     

    The error is suspect.
    I can't find libmraajava.so .
    However, the mraa-2.2.0.aar file does not contain libmraajava.so in jni.

    It doesn't work with what I received from the official address above, so what's the problem?

    Code for the problem mraaJNI.class found by debugging.

    Additionally, when executing code to call GPIO, you get a [ libmraajava.so not found ] error as you go to the static try {} catch {} just above

     

    import mraa.Gpio

    import mraa.Dir

     

    var gpio = Gpio(1) // error code start...
