@kcubeterm Why closing? Is this not feasible for this app?

This will not allow storage of termux app data like $HOME and $PREFIX on the external removable sd card, it will just allow installation of APK on external storage.

The .apk file is saved on the external storage, but all private user data, databases, optimized .dex files, and extracted native code are saved on the internal device memory.

Moreover, check Applications that should NOT install on external storage section. This will cause problems with termux service, boot receiver, widgets, etc. Saving ~80MB (which may reduce to ~20MB in future) is not worth all the mess this will create.

I see... Thank you for explaining.

welcome.
