I receive the following error message when trying to create an APK using Buildozer:

Hi Mabel,

Inside your buildozer.spec file have you set log level to 2?

If you haven’t, do so and repeat the error and post it here with extra information.

Normally a log level 2 will indicate a dependency issue or perhaps the device you are attempting to build to is not the correct API level.

So from what I can see it could be a python for android error. But I’d need to see more detailed logs to assist further.

Michael.

Hi,

Thanks for your reply.

I'm testing different SDK versions and different arch, and I found different issues so far:

r17c - armeabi-v7a

[WARNING]: lld not found, linking without it. Consider installing lld if linker errors occur.

clang++: error: linker command failed with exit code 1 (use -v to see invocation)

make: *** [/Users/Mabel/work/LEGEC/draft4_android/.buildozer/android/platform/build/build/bootstrap_builds/sdl2-python2/obj/local/armeabi-v7a/libmain.so] Error 1

r19c x86_64 --> here was missing the prebuilts of gcc that I did downloaded from github

[WARNING]: lld not found, linking without it. Consider installing lld if linker errors occur.

See `config.log' for more details

I don't know what to do anymore.

Please, help me!

Thanks a lot for you attention

Mabel

Okay. I had a look. It’s a big log lol lots to read.

- - this is where it starts (the error)

#### I’m not completely sure as I’m not familiar with this SDK but it seems lpython2.7 and lpython2.7 -lstdc++ -lc -lm -o could be an issue. Find out more about anything you can install dependency wise for this lpython2.7. Don’t be shy about it. Install everything you can. Using brew or pip #######

#### Below are lots of undefined references. I’m not entirely sure how you acquire those but I would say it’s a dependency problem. It usually always is. #####

#### I’m not sure either oh your syntax being used. But to me it looks python 2.7 specific t missing modules. Google some more but that’s the best I can do right now. Google module names and the errors you get below. Just the error not all the other bits. Anyway, if I can help more let me know. I would just start with what I’ve mentioned and try again #####

Hi! Did you fix this problem now ?Now I have the same trouble here.Some one tell me to install the LLVM, I do it, but it doesn't work.If you fix it, please tell me the way how to fix it.My email is nghing...@gmail.com

Hi Hinglam,

No, I can't fixed this problem on OSX. I really struggle in this task for over 3 weeks, and nothing.

I decide to go back to linux and run my app for android from there. This is the best choice if you have a deadline to fulfill.

If you decide to do the same I can give you some tips to make it work.

Best regards

Mabel

Hi Hinglam,

You can give a try! Unfortunately, I have no memory left in my macbook, so this is one of my problems to deal with buildozer.

In the linux machine it works using this set of data:

* java8 (jdk)

* buildozer downloaded from git

* cython =0.25

* download SDK manually: build-tools

platforms

platforms-tools

tools

In buildozer (SDK path = /home/SDK/) put the directory in which you save the SDK tools.

* python2.7 - it works just for a python2 requirements.

If you succeed in this attempt, let me know!

I hope to hear from you soon.

Best regards

Mabel

Here are some more detailed instructions, for a related task.

These are not what you want as they are Linux/Android/Python3/p4a

But they do show how to download and build the Google SDK, jdk8, etc.
