App crashing on startup- ImportError: dlopen failed: _imaging.so is 64-bit

[zoemaestra]

EDIT: https://github.com/kivy/kivy/issues/4095 seems to be the same issue, but nobody has gotten an answer from there.

Hi, when I run an apk which has the pillow imported in it (from PIL import Image) it will crash on startup citing this, and force closing:
ImportError: dlopen failed: "/data/data/org.benjimaestro.hypertext/files/app/lib/python2.7/site-packages/PIL/_imaging.so" is 64-bit instead of 32-bit

I am using Python 3.5 64bit on Ubuntu 64bit. The Pillow module was installed with pip.

[inclement]

Thanks for the report, it sounds like the PIL recipe has a bug.

[AndreMiras]

Well it could have a bug indeed, but your buildozer.spec seems wrong to me. Since you've added both pil and pillow in here:

requirements = kivy,hostpython2,plyer,android,pil,pillow

But pillow does not (yet) have a recipe, see #786.
So the error you're having would definitely happen if you try to build/install an extension which has no recipe. Even if the pil recipe was not broken ;)

Edit:

I could successfully test the PIL module on my install. Since you installed pillow once, you need to make sure it's completely cleared before trying again with PIL. I remember I had some issues with that where the previous pillow install was remaining. You could try to manually delete the Android application as well as running:

buildozer android p4a -- clean_recipe_build pil

Before doing your build and deployment again, good luck :)

[inclement]

Thanks @AndreMiras, I'll close this. If there are specific issues with the pil recipe, feel free to open a new issue about them.

For what it's worth, I intend to look at fixing up the recipes after the next release.

I've been trying to fix this error for a pretty long time. I did what you said and now my app is running on Android. Thank you @AndreMiras You are my personal jesus christ :)

How to solve the question?I I haven't found a way to find it for a long time.

[ghost]

@Subdue0 you need to add the exact variant that has a p4a recipe to your --requirements as in the p4a option, or if you use buildozer, the buildozer.spec requirements entry. Adding it to your project's requirements.txt or similar is not sufficient. For a python 2 app, both pil and Pillow should work, for Python 3 use Pillow. Also, I'm not sure the recipes are in working order in p4a's stable, so you may need to use the git master development version. (someone else can possibly correct me on this) You can install the p4a dev version using pip install -U https://github.com/kivy/python-for-android/archive/master.zip

And try what @AndreMiras suggested above, which is:

1. Remove your distribution folder (usually named unnamed_dist_1 or similar in the p4a build subfolder, you should be able to find it on Linux using sudo updatedb && locate unnamed_dist) such that it is recreated from scratch next time
2. Use buildozer android p4a -- clean_recipe_build pil

Hope that helps. You can also drop by on the discord where we might be able to help you better

[Subdue0]

@Jonast I have tried all of the above, but none of them can be solved. My p4a 's 'recipes' contains Pillow and pil, no pillow, and if i use 'pillow' in the requirements, it can be successfully packaged, but the APK cannot be run ('_imaging.so" is 64-bit instead of 32 -bit'), the other will have errors when packaging.

[ghost]

if i use 'pillow' in the requirements

On recent stable this might give you no recipe. That will obviously build but not anything useful (as evidenced by the error at runtime).

the other will have errors when packaging

If you don't give us the detailed errors, nobody can help you 😢

It appears as if p4a doesn't pass the correct the NDK version along to the NDK makefile to me. I don't think this is related to pil/Pillow in any way, it looks like a generic p4a bug. Can you file a new ticket with this backtrace so we can see what needs fixing?

(My spontaneous guess is that the ndk-build call quoted in RAN would need to add the APP_PLATFORM option, but I'm sure other devs also have some ideas)

Also what p4a version is this? Could you possibly try git master if this is the pypi or some other stable/older version to see if that changes anything?

[ghost]

Just to clarify: with new ticket I mean create one here: https://github.com/kivy/python-for-android/issues/new you could title it ndk-build error during build or something
