After a successful build using python makepanda/makepanda.py --everything --target android-21 --no-tiff --installer --threads=4, I could install the APK using the files app (xdg-open didn’t work).
After running ./run_pview.sh /sdcard/models/panda.egg from the panda/src/android folder, I get the following in logcat:

After a quick find, I found that file at “/data/data/com.termux/files/usr/lib/libc++_shared.so” and copied it into built/lib. After re-running the build and reinstalling the app, I get AndroidRuntime: java.lang.UnsatisfiedLinkError: dlopen failed: library "libfreetype.so" not found
I could keep drilling in and looking up each one, but perhaps there is a better way? Is something wrong with the build system?
Okay, so the problem there was that it didn’t look at the linker paths correctly, only using the LD_LIBRARY_PATH environment variable. Finally I added a mildly dirty fix to the makepanda/makepackage.py file:
diff --git a/makepanda/makepackage.py b/makepanda/makepackage.py

Now I get the following issue:

What’s interesting here is that when I checked the directory that the app was installed to (/data/app/org.panda3d.sdk-e0VkIIJU3JLNCbUBj9_YFw==/lib/arm64), I found libssl.so there. So now I got no idea why its not finding it.
BINGO! Turns out I also had to change the SONAME of all the libraries to match their new names.
Here is the final patch:

@rdb Is this good enough for a PR or should I attempt to clean up the ld parsing?
Hi, usually libssl may get old on device that’s why you may want to use a newer one and embark it in the app/lib folder. cpython has also some specific requirements about ssl support since 3.7+.
Are you interested in cross compilation of CPython and Panda3D ? Api 19 (kitkat 4.4) has some support and also basic support for non native application ( eg Panda3D on SurfaceView )
