@Ste_W pointing to hosting a tiddlywiki somewhere where both the Windows device and android device is possibly the most robust approach.
With the other methods you are forced to make some choices such as which device is the host, or reference copy. One of the best I have seen (but not easy to use) is hosting the wiki on android with termux, basically you access the wiki on the android when at home via windows and local Wi-Fi to the phone. Depending on your needs such as a private wiki.
Other solutions work based on;
- One drive, Google Drive, Dropbox and others
- Accessing the wiki on a phone via wifi or USB cable
- Aforementioned hosting
- Using file synchronisation
