# Zcash Android SDK
This lightweight SDK connects Android to Zcash, allowing third-party Android apps to send and receive shielded transactions easily, securely and privately.
# Hush Android SDK
This lightweight SDK connects Android to Hush, allowing third-party Android apps to send and receive shielded transactions easily, securely and privately.
Different sections of this repository documentation are oriented to different roles, specifically Consumers (you want to use the SDK) and Maintainers (you want to modify the SDK).
Note: This SDK is designed to work with [lightwalletd](https://github.com/zcash-hackworks/lightwalletd). As either a consumer of the SDK or developer, you'll need a lightwalletd instance to connect to. These servers are maintained by the Zcash community.

Note: Because we have not deployed a non-beta release of the SDK yet, version numbers currently follow a variation of [semantic versioning](https://semver.org/). Generally a non-breaking change will increment the beta number while a breaking change will increment the minor number. 1.0.0-beta01 -> 1.0.0-beta02 is non-breaking, while 1.0.0-beta01 -> 1.1.0-beta01 is breaking. This is subject to change.
# Zcash Networks
# Hush Networks
"mainnet" (main network) and "testnet" (test network) are terms used in the blockchain ecosystem to describe different blockchain networks. Mainnet is responsible for executing actual transactions within the network and storing them on the blockchain. In contrast, the testnet provides an alternative environment that mimics the mainnet's functionality to allow developers to build and test projects without needing to facilitate live transactions or the use of cryptocurrencies, for example.
The Zcash testnet is an alternative blockchain that attempts to mimic the mainnet (main Zcash network) for testing purposes. Testnet coins are distinct from actual ZEC and do not have value. Developers and users can experiment with the testnet without having to use valuable currency. The testnet is also used to test network upgrades and their activation before committing to the upgrade on the main Zcash network. For more information on how to add testnet funds visit [Testnet Guide](https://zcash.readthedocs.io/en/latest/rtd_pages/testnet_guide.html) or go right to the [Testnet Faucet](https://faucet.zecpages.com/).

This SDK supports both mainnet and testnet. Further details on switching networks are covered in the remaining documentation.

1. Intel-based machines may have trouble building in Android Studio. The workaround is to add the following line to `~/.gradle/gradle.properties`: `ZCASH_IS_DEPENDENCY_LOCKING_ENABLED=false`
1. During builds, a warning will be printed that says "Unable to detect AGP versions for included builds. All projects in the build should use the same AGP version." This can be safely ignored. The version under build-conventions is the same as the version used elsewhere in the application.
1. Android Studio will warn about the Gradle checksum. This is a [known issue](https://github.com/gradle/gradle/issues/9361) and can be safely ignored.
## Compiling notes for Hush
We currently rely on mavenLocal publishing for the SDK. Run the following commands to build and publish the SDK locally before compiling the Android wallet.
```
./gradlew clean
./gradlew build
./gradlew build publishToMavenLocal
```
On Windows you may also need to manually create the following directory if build fails for it not existing:
