[xtkoba]

Problem description

Please explain why this package is needed. I'm going to remove this if no explanation is provided.

What is the expected behavior?

#16680 (comment)

If you have better ideas feel free to break the package

[xtkoba]

I'm not familiar with Termux Docker, but is it true that it does not have /system/lib(64)?/libandroid.so?

[xtkoba]

Note that there are other packages (e.g. mpv, libgnustep-base) that link against libandroid.so. They also won't work on Termux Docker without libandroid package, if ffmpeg doesn't. We should be consistent in that.

Yes and I suggest you to use it if you can fix this in better ways

[xtkoba]

What do you mean by "it" if it does not exist?

[truboxl]

By it I mean https://github.com/termux/termux-docker

[xtkoba]

Then my opinion is Termux Docker is broken and it should be fixed so that it includes system libandroid.so. libandroid.so is assumed to exist on every Android environment.

[xtkoba]

And normal Termux environment should not require libandroid package.

[xtkoba]

FYI, system libs that are assumed to exist:

libEGL.so
libGLESv1_CM.so
libGLESv2.so
libGLESv3.so
libOpenMAXAL.so
libOpenSLES.so
libandroid.so
libc.so
libcamera2ndk.so
libdl.so
libjnigraphics.so
liblog.so
libm.so
libmediandk.so
libstdc++.so
libvulkan.so
libz.so

IIUC Termux Docker is not an officially supported environment. So IIUC no problem if the dependency of a package is specified so that it may be insufficient for Termux Docker.

I understand libandroid package itself is useful for some environment and I won't remove it from our repo. Please manually install libandroid package if necessary.

(Honestly I don't want to check every package if it depends on libandroid.so.)
