PSBT Extend

val sdk = KeystoneSDK()
val encoder = sdk.btc.generatePSBTExtend(psbtBytes, coinId = 2)
val result = sdk.btc.parsePSBTExtend(ur)
// result.psbt: ByteArray; result.coinId: Int? (null for an omitted Bitcoin coin field)

Supported coin IDs: 0 Bitcoin (omitted in CBOR), 2 Litecoin, 3 Dogecoin, 5 Dash, 145 Bitcoin Cash.

Build with an installed Android NDK and JDK 17 (the Gradle 7.6.1 wrapper does not support JDK 21):

export ANDROID_NDK_HOME="/path/to/android/ndk"
./gradlew :library:assembleRelease

The preBuild task builds the Rust submodule and copies all four ABI libraries. The AAR is generated in library/build/outputs/aar/.
