Switch from pygame to sdl2 easily

[Tungsteno74]

Hello,
Is possible to switch the engine from pygame to sdl2 in buildozer?
I have not seen any setup string about the engine in buildozer.spec file.

I ask this because I have a problem with the size of some widgets that are not positioned / sized as expected. They seem to be different than in windows or linux with sdl2.
Android system: 4.4.2 on galaxy s3 neo (gt-i9301i)

thanks and sorry for my bad english.

[pythonic64]

You can install master version and use target "android_new" which will build with SDL2.

[Tungsteno74]

I did this:
pip install --upgrade buildozer --target android_new
Without uninstall the preview version (with pygame).

buildozer -v android debug this work for start the debug with sdl2? or need some other parameter?

thanks

[pythonic64]

What I meant is:

• Clone buildozer master branch
• Inside cloned directory do python setup.py install
• And then in your app directory run buildozer -v android_new debug

I think that pip install --upgrade buildozer --target android_new will not work.

[Tungsteno74]

Oh ok man, thanks. This work but raise the following problem when debug:

Where can i found the sh module?

[pythonic64]

I think you can install it with pip install python-sh or with apt-get install python-sh.

[Tungsteno74]

i found sh with pip install sh but not python-sh. This is the same?

[pythonic64]

I'm not currently on Linux, so I don't know for sure. You can always uninstall it if it isn't the same.

[inclement]

Yes, sh is the module name.

[Tungsteno74]

Seem to be working with sh instead of python-sh, but now i have another error:

This seems a lot of strange for me. The pygame version did not give these errors.
Is it possible that so many libraries missing with the new toolchan?

Someone have a working android_new toolchan to send?

[inclement]

These are dependencies of python-for-android that buildozer does not (yet) install automatically. Feel free to open an issue about this specifically. For now, just install the missing modules manually.

[Tungsteno74]

ok thanks i will try.

[Tungsteno74]

Can i use this thread to make a list of missing dependencies that i found in the sdl2 toolchan?
I ask this because I found other missing modules. So if someone else uses the same toolchain and has the same mistakes he can check them here.

I added sqlite3 in buildozer.spec but raise the following error:

i've tryed to install it with sudo pip install pysqlite but request a sqlite3.h file:

I am unfamiliar with indeep change in buildozer code, so i removed it from buildozer.spec (i can't fix)

[inclement]

There is not yet a sqlite3 recipe in the new toolchain, but there is a PR for one.

[Tungsteno74]

Are you saying that they are interchangeable?

I don't know PR. I'm not able to find a package with this name on the web. Can explain me please?

Excuse my ignorance
PR = project ? if so i go ahead.

Another error, this time is not for a missing module:

There is a fast fix? Or i need to go indeep?

[inclement]

This is a known bug. The workaround is to add 'hostpython2' in the requirements.

Also, PR is pull request. In this case it is a submission to python-for-android, not buildozer, you can find the current PRs in the python-for-android github repository.

[Tungsteno74]

@inclement Oh thanks for your explanation. I am unfamiliar with abbreviations used in repositories.

[Tungsteno74]

fixed with sudo pip install Jinja2

[Tungsteno74]

OK, now the build process work.

@inclement
I have a problem when deploy run the test app on device with sudo buildozer android_new deploy run.
I post the error here or open a new issue?

I found a similar issue, Touchscreen input with SDL2 bootstrap #516, but i see only the presplash.
