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.

- Enhanced implementation of SaplingParamTool component. It got sapling files move from legacy folder to the preferred one functionality. It downloads the sapling files atomically now (through the temporary file names). It contains all related constants now. It works with SaplingParamToolProperties, which allows us to easily test the SaplingParamTool functionalities. It also now checks file hashes. Removed unnecessary clear function from the component. Changed valid function.
- Moved related constants from ZcashSdk class to SaplingParamTool class
- Changed Initializer, WalletTransactionEncoder and RustBackend classes to work with File instead of path String
- Minor changes in comments in other classes
- Added getSha1Hash() extension function to the FileExt class
* Related tests
- Two new test fixtures to simplify our tests
- Test for getSha1Hash() extension function
- Minor changes in existing tests
- Created new SaplingParamToolBasicTest, which covers non-integration functionality of SaplingParamTool
- Moved integration tests of the SaplingParamTool to the new SaplingParamToolIntegrationTest and added some new
* Related manual tests
- Created Download sapling files manual test
- Created Move sapling files to no_backup manual test
- Update existing Move database files to no_bakcup manual test

* [#509] Remove OkHttp and Okio dependencies
- Okio -> Java NIO anf OkHttp -> HttpURLConnection in SaplingParamTool class
- Both replaced also in the test packages
- Removed dependencies to the replaced components
- Again switched a few assertions from JUnit to kotlin.test
- Created readLinesInFlow() function which is now reused in few places and runs without OkHttp
- Added subsequent TODOs to code base
- Wrapped to withContext to move it to an IO thread.
- Added use function on the stream and close() at the end of the channels use.
