Install APK

What happens if my t*.apk will installed on a Q/10 device and opened (bash) or is it not possible:
type bash is non-native(~/u)? Four shots to install and use of example check see README:

• 1 Startscreen with Termux and X-Server plugin on my current P/9 device
• 2 QuickEdit-App to view sources - for comparison with check.
• 3 Termux-App with process control (pp) start/log of example (t/c) alias/env check
• 4 XClient (check.exe) in X-Server to view sources (here *.xpm) -source in preraration.

The action is simple with Android 9. To do the same in 10/API-29 would have to be u/bin u/lib (ln -s ~/../usr ~/u) and ~/check.exe ($s) in native /system.
@xeffyr said Yes to Could the APK solution be tested on Andriod-9? How does it work?

Github has a limit that my-t77.apk (63Mb) can not be saved - is also here and created with apksigner. There are also the versions 0.73 (smaller but needs package update) and 0.82 to find. An exchange of the 'my-t*.apk` (same signing) has no restriction of the check function to follow.

@fornwall made a (proot less) suggestion in dev - where do I find (and how to use) the
'termux-package-binary' and do you've an example of a script?
