MK908 Rockchip RK3188 mini PC Android 4.2.2 SDK Leaked

We’ve had the Linux source code for RK3188 for a little while, which allowed a preliminary Ubuntu image to boot on devices such as Tronsmart T428. But AFAIK, we did not have any Android SDK for RK3188 HDMI TV Stick, until now. A new user on ARMTvTech has uploaded 5 rar files that can be decompressed into a single 3.2GB file called mk908_RK3188_R-BOX_ANDROID4.2.2-SDK.tar.gz.

I’ve had a look, and this is the content of the file which appears to be a complete Android 4.2.2 SDK for MK908.

There’s 2 documents in Chinese:

  • mk908_checklist.doc – Apparently some instructions, or recommendations specific to Android
  • MK908_checklist_kernel.docx – Some details about the kernel config

There are also more documents and directories in RKTools/docs, but I haven’t checked the details:

Back to the root directory, we’ve got a Makefile, and script, but both are called by script which apparently builds all, and generates a firmware upgrade image. I’ve tried to run, but the build failed with the following error:

make: *** No rule to make target out/target/common/obj/APPS/Calendar_intermediates/classes.jar', needed by out/target/common/obj/APPS/CalendarTests_intermediates/classes-full-debug.jar’.  Stop.

I haven’t tried to investigate the error further. If one of you is successful with the build, please do let us know.

    a) adb use: Please refer to the adb instructions RK3066 Android4.2.2
    b) kernel directory has a subdirectory as the android exist, if kernel directory location
    To make a change, it would need to re-set the kernel’s default position.
    The specific method is to set the ics/device/rockchip/rk31sdk/
    kernel the default location that TARGET_PREBUILT_KERNEL value of this variable;
    Four cases related tools
    As this SDK only supports RK31, users can perform without lunch, directly make
    Compilation. But “R-Box Platform User Manual” in the introduction of compiling party in BOX SDK
    Method to be effective. Also note that there are RK packaged remote control, infrared remote control, wifi
    display and other related instructions.

    Ta -is that useful? I don’t really know :p But if so, these might be too:
    android分区修改说明.pdf – “amend partitions explanation”
    ROBX-SDK 发布说明(RK3188_R-BOX_ANDROID4.2.2-SDK_V1.0.0_130514).pdf – also release notes.

    I notice it only seems to support 1GB RAM???

    How are MK908s different from the MK809 III? (That one seems to be available cheaper & a 4GB RAM might come out soon…)

  3. @onebir
    There’s a lot here – 7.5GB once installed – I think previously we’ve only been provided with the kernel sub-directory for the equivalent MK802IV so this looks interesting. I’ve noticed the IGB RAM references in a number of places so perhaps this info is somewhat dated? Key difference between MK908 and MK809 III (for compiling Linux) is the wifi/bt chip. Pricing seems similar at USD 64.99 vs USD 67.99 from a well known retailer who provides shite customer support :-0

  4. Well, if you can get Linux working nicely on any of these RK3188 sticks it’ll be an amazing amount of computing power for the price &/ size! 🙂 Best of luck mate!

  5. @cnxsoft
    How did you manage to upload anything there?

    All I get is: “interdit” – I wonder why that would be – or “Virus detecté, fichier détruit et banni…” – aaah! Really!?- , when I try to upload a tiny test file like “autorun.inf” (43 B) or “setup.exe” (110kB) from a guaranteed virus-free printed DVD or /tmp/MozUpdater/updater.png (3.9kB) from my Linux Mint system.

    Their web-based upload file testing/AV-check simply is bonkers 🙁

  6. Hi:


    In order to compile Android with this SDK two “” files should be changed to “”

    ./RK3188_R-BOX_ANDROID4.2.2-SDK_V1.0.0/packages/apps/Calendar$ ls
    AndroidManifest.xml extensions_src MODULE_LICENSE_APACHE2 NOTICE proguard.flags res src tests
    ./RK3188_R-BOX_ANDROID4.2.2-SDK_V1.0.0/packages/apps/Calendar$ mv

    ./RK3188_R-BOX_ANDROID4.2.2-SDK_V1.0.0/packages/apps$ cd Mms/
    ./RK3188_R-BOX_ANDROID4.2.2-SDK_V1.0.0/packages/apps/Mms$ ls AndroidManifest.xml MODULE_LICENSE_APACHE2 NOTICE apptests proguard.flags res src tests
    ./RK3188_R-BOX_ANDROID4.2.2-SDK_V1.0.0/packages/apps/Mms$ mv

    cd ~/RK3188_R-BOX_ANDROID4.2.2-SDK_V1.0.0/

    source build/
    make -j4
    (if “make -j4” fails the first time try “make -k”, wait, and then do again a “make -j4”)

    Happy hacking, and cnx readers please publish advances related to the mk908 and post a link here
