* [#631] Initial Compose scaffolding for demo app
* Bump Compose Compiler
- To bypass Kotlin version incompatibility
* Switch ConfigureSeed from Column to Scaffold
- To unify our screens UI components
- And to have a fullscreen content, and thus avoid another background color out of column (e.g. in system dark mode)
* Split addresses to two rows
- To reduce a risk of a user overlooks other addresses scrolled out of the screen
* Additional code migrated from Secant
- Added just missing test files, fixtures and model classes
- Fix previously broken dependencies imports
* Link issue to code

The Android and Rust code have previously managed joint custody of the derived data database. With more complex migrations now required, we need to make the Android side read-only. To achieve that, the Android side will remove Room and instead rely on more primitive SQLite APIs for read-only access.
As part of implementing this change, database management throughout the SDK is being refactored.
There will be multiple representations of the data:
- Database representation (and some Entity representations in the places that Room hasn’t been removed yet). These representations are not as type safe and don’t match Kotlin best practices in all cases.
- Once #615 is implemented there will also be network representations
- Type safe models, which often appear in the public API The Database and Network representations will be converted to and from the type safe model representation.
The SDK now exposes UAs primarily, with additional methods for obtaining
corresponding Sapling and transparent addresses for legacy compatibility.
The `Account` DAO is also fixed to use the migrated `accounts` table format.
The demo app now shows the current UA and the legacy Sapling and transparent
addresses.
Closeszcash/zcash-android-wallet-sdk#677.
This change leverages the gRPC streaming API along with the elimination of bulk inserts to SQLite to reduce the amount of memory required to write blocks.
- Replace int with type safe BlockHeight(Long) object
- Fix down casting bug, as BlockHeight is uint32 but Java only supports int32 or int64
- Rename WalletBirthday to Checkpoint and hide from the public API
While there are a lot of changes, the most significant are:
- Update the main entrypoint of the SDK to use a suspending function and eliminate lazy initialization. This also resolves#310
- Changing Dao methods to `suspend`, allowing Room to implicitly manage the threading model under the hood
- Explicitly set the executor thread for the `CompactBlockDb` and `DerivedDataDb`, which is the same thread used when calling into the Rust native library. Room will then use this thread for `suspend` fun calls into it
- With the above set, remove unnecessary hops to Dispatchers.IO which is a thread pool
- Eliminate lazy initialization in `PagedTransactionRepository` to make it easier to reason about the threading model and resolve#355 where the database was being touched from the UI thread
Note that `PendingTransactionsDb` is not opted into this single-threaded approach, because that database is not shared with the Rust code
To quickly get this implemented, some calls in the demo-app have been wrapped in `runBlocking {}`. This is not ideal and will be addressed in followup issues.
In the process of refactoring the Gradle scripts, ktlint now is applied to all Gradle modules. The demo-app hadn't been linted before, so this applies a series of minor autocorrections to this module.
Some tests have been disabled to enable tests to actually complete; there are a number of test failures which need to be addressed.
These tests were failing prior to the refactoring.
The disabled tests can be easily found by searching for the Ignore annotation. They also appear in the Junit results window in Android Studio.
Move SDK from the root gradle project to its own Gradle module
Move the demo app to be a peer of the SDK
This will simplify integration with CI on Bitrise.
