I successfully setup android studio to compile a debug lk8000 apk.
My problem is that that the conditional:
#ifdef __arm__
is always false when I run the apk in the target device (I'm working on color e-ink support).
So, all the code that depends on that conditional is not executed. What should I do to compile it properly? Unfortunately I am not familiar with C++ and android studio. |

I don't know, I did not set it because I don't know what it is and how to set it.
I just exported the code from github, import it in android studio and then do Build -> Make Project from the menu.
I copied the generated file android-studio/app/build/outputs/apk/debug/LK8000-7.1p-debug.apk from the computer to the device and installed it, where it works except that #ifdef __arm__ parts are not taken into account.
The device where I test the apk is an HiSense A5 Pro CC.
By the way, I can't run LK8000 in the emulator because after it starts I just see a black screen (even tough sound and mouse clicks seem to work), I don't know if this is related.

I tried to set the abi:
menu Build -> Select Build Variant
then I set "Active ABI" to armeabi-v7a, rebuild everything, but didn't work: still __arm__ not defined.
Same thing for arm64-v8a.
I even tried doing:
menu Build -> Edit Build Types -> Variables -> :app -> new variable
set __arm__ to value "y"
with no luck :-( |

| abi depends of target device only, so for arm64 device "__arm__" is not defined, instead "__aarch64__" is defined ... |

| Could you give me a hint on the correct way to compile for android with DITHER and GREYSCALE defined? |

| "DITHER" and "GREYSCALE" can't be defined for OpenGL Target and Android is OpenGl target. |
