node_modules/bdk-rn/android/src/main/java/io/ltbl/bdkrn/BdkRnModule.kt:450:21 Comparison of incompatible enums '[Error type: Not found recorded type for addressIndex.getType()]' and 'ReadableType' is always unsuccessful

so bdk-rn is not working on android? Since I cant run the app in android emulator... only on iOS?

in addition to the above my build was also failing as shown

e: file:///home/ojokne/Documents/BDK/node_modules/bdk-rn/android/src/main/java/io/ltbl/bdkrn/BdkRnModule.kt:724:52 Argument type mismatch: actual type is 'ReadableMap?', but 'ReadableMap' was expected.

I applied the fix in #87 and the following

updated addUtxos function

fun addUtxos(id: String, outPoints: ReadableArray, result: Promise) {
    Thread {
        val mappedOutPoints: MutableList<OutPoint> = mutableListOf()
        for (i in 0 until outPoints.size()) {
            outPoints.getMap(i)?.let { readableMap ->
                mappedOutPoints.add(createOutPoint(readableMap))
            }
        }
        _txBuilders[id] = _txBuilders[id]?.addUtxos(mappedOutPoints)
        result.resolve(true)
    }.start()
}

updated unspendable function

fun unspendable(id: String, outPoints: ReadableArray, result: Promise) {
    Thread {
        val mappedOutPoints: MutableList<OutPoint> = mutableListOf()
        for (i in 0 until outPoints.size()) {
            outPoints.getMap(i)?.let { readableMap ->
                mappedOutPoints.add(createOutPoint(readableMap))
            }
        }
        _txBuilders[id] = _txBuilders[id]?.unspendable(mappedOutPoints)
        result.resolve(true)
    }.start()
}

updated setRecipients function

fun setRecipients(id: String, recipients: ReadableArray, result: Promise) {
    Thread {
        val scriptAmounts: MutableList<ScriptAmount> = mutableListOf()
        for (i in 0 until recipients.size()) {
            recipients.getMap(i)?.let { item ->
                val amount = item.getInt("amount").toULong()
                val scriptId = item.getMap("script")?.getString("id")
                if (scriptId != null) {
                    val scriptAmount = ScriptAmount(_scripts[scriptId]!!, amount)
                    scriptAmounts.add(scriptAmount)
                }
            }
        }
        _txBuilders[id]?.let { builder ->
        _txBuilders[id] = builder.setRecipients(scriptAmounts)
        result.resolve(true)
    }.start()
}
