If you can get the new version of DB Navigator to work e.g. on a different phone, or if it is already working e.g. on a different phone …
- On the phone where it works, additionally install SAI Split APKs Installer (F-Droid / Play Store).
- Use SAI to export the split APK of the new version of DB Navigator.
- Transfer the exported split APK file to the phone where DB Navigator doesn’t work.
- Install SAI there, too, and use SAI to install the split APK.
Confirmed working with DB Navigator 19.10.p03.02 on lineage-16.0-20191119-microG-FP2.zip. (Solution originally found here.)
