TODOs: Userdata collection This sets up the userdata syncgroup among the same user's devices. When the user creates a new todo list, the other devices will also join that todo list collection. We currently shard by email address and use a common cloud. Caveats: - Since we can only create syncgroups underneath an existing syncbase, and merging is not supported, the same user must be sure to start one device a bit before the other to avoid a creation race. - Discovery between syncbases has occasional errors saying that ads are too large on both the creator and joiner sides. This is expected, but we need a hack to syncbase to ensure that the cloud is published too. https://vanadium-review.googlesource.com/22043 - Similarly, the aforementioned CL is used to improve stability after a user's 2nd device joins the todo list. It won't crash if a local publish of Vanadium uses that patch. https://github.com/vanadium/issues/issues/1314 - If you run with vlog, the app runs out of memory eventually and crashes. This bug already existed though, IIRC. - There are occasional errors in go-jni. "Error while importing keypair: -1 panic: Reference 42975 doesn't exist" as well as "panic: runtime error: cgo argument has Go pointer to Go pointer" https://github.com/vanadium/issues/issues/1315 This only starts to happen after syncing and seemingly occurs randomly.

This is a TODOs application for Android which uses either Firebase or Syncbase as a persistence layer.
To switch between Firebase and Syncbase use: Build -> Select Build Variant and choose between the various options (e.g., firebaseDebug, syncbaseDebug etc.)
The firebase app is at https://vivid-heat-7354.firebaseio.com/. Ross Wang and Alex Fandrianto manage the administration of the database.
WARNING: There is no authentication required in this demo, and the TODO list is global, accessible to all. In a real TODOs app this would not be the case of course. In the mean time, don't put anything sensitive there!
