Is it possible (and allowed) to bundle Termux libraries and executables to be used in other standalone Android apps?

[s-cerevisiae]

I'm struggling to bundle and run some Python (or JavaScript) services as a part of a standalone Android app. There was almost zero information on how to do this with any kind of framework (like python-for-android which only gives minimal instructions and is not a general solution).

I'd like to know if I can use the binaries/build scripts of termux-packages to help me bundle Python or NodeJS servers into an Android app. Much appreciated if instructions are also given.

Zero information because it is a very specific unsupported case. Termux executables are not portable.

For now you have only these options:

1. Use com.termux as application package name and as result your app and Termux can't coexist on same device.
2. Ensure your application's package name length equal to yours, then try to run sed over executables to replace com.termux with own app.pkgnam (remember, length must equal).
3. (the most correct and easy way) Build packages with own prefix instead of /data/data/com.termux/files/usr

Also there are hard requirements:

• Your application must have target SDK level 28 or below. Why so: Revisit the Android W^X problem termux-app#2155
• You should copy all dependencies, ensuring com.termux was fixed as well.

What sylirre said is correct. Additionally, regarding sylirre's third listed option:

3. (the most correct and easy way) Build packages with own prefix instead of /data/data/com.termux/files/usr

I also strongly wanted that functionality, and I practiced doing that for a long time, so eventually, in order to more easily manage and organize my method of doing that, I have created, and have continued maintaining for some time, a helper tool which can build Termux packages automatically into an autogenerated APK that has the name changed from com.termux to any other chosen name.

https://github.com/robertkirkman/termux-generator

The resulting outputs of my tool are:

• An autogenerated APK (plus other APKs derived similarly from the code of the Termux addon APKs like Termux:Boot) with whatever packages and APK name you choose, which is initially very similar-looking and similar-behaving to Termux, with all Termux Terminal features included by default
• Full source code of that APK, which you could optionally edit further to insert your own Android Activities and other frontend components
• One or more architecture-specific Bootstrap .zips for that APK, containing all the packages which were chosen to build, which can also be transplanted manually into any other custom app with the same App Name if it is desired to start from scratch and not use the normal Termux-based frontend Activities.

It is important to keep in mind that my project is an unofficial tool and is not an official Termux project, but I have been told it is OK for me to mention my project if someone is asking about this topic very explicitly like you have.

If you decide to use my tool, please keep that in mind and remember to open any issues you encounter with it in https://github.com/robertkirkman/termux-generator/issues, where I can help you one-on-one, and not in github.com/termux.
