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.

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;

Ta -is that useful? I don’t really know :p But if so, these might be too:

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…)


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


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!


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 🙁


Ahh, I see. They then probably used ftp upload to bypass that crazy web-virus-check nonsense.


[…] 10 days ago, Android 4.2.2 SDK for MK908 (RK3188) HDMI TV Stick was leaked, and now, I’m reporting another leak, this time for the Android 4.2.2 SDK for the […]




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

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
