litecoinj's Issues

Tutorial Please

If it is not too much work could someone link a video tutorial or a readme tutorial on how to get this working.

IllegalStateException: Length field has not been set in constructor for UnknownMessage after parse.

anyone else seeing below stacktrace when constructing WalletAppKit using org.litecoin.test (TestNet3Params) and have a proper workaround (that doesn't involve a try/catch hack)?

the exception does not cause application to crash, but rather is thrown over and over- ad infinitum. strangely at one point, the below exception stopped for several hours- then reappeared.

it appears to be specifically recurring about failed de-serialization of this message (and nothing else):

5c0100000015f7675900000000ffffff7f00000000ffffff7ffeffff7f0000000000ffffff7f00ffffff7f002f555247454e543a20416c657274206b657920636f6d70726f6d697365642c2075706772616465207265717569726564004630440220405f7e7572b176f3316d4e12deab75ad4ff978844f7a7bcd5ed06f6aa094eb6602207880fcc07d0a78e0f46f188d115e04ed4ad48980ea3572cb0e0cb97921048095

the critical parts of the stacktrace are:
org.litecoinj.core.BitcoinSerializer : No support for deserializing message with name alert
and
java.lang.IllegalStateException: Length field has not been set in constructor for UnknownMessage after parse.

here's the full stacktrace:

TestNet dnsSeeds do not seem to exist

The TestNet3Params has 3 dns names hardcoded in for the dnsSeed array values (below). NONE of these 3 dns names even resolve anymore, let alone ping/work. If I use the MainNetParams everything works fine (albeit a good 30 minute first time load of Wallet/WalletKit to sync spv chain). If there are updated testnet config values, would be great if these were merged in. If LiteCoin testnet just not supported/working anymore, that would be nice to know as well.

    dnsSeeds = new String[] {
            "testnet-seed.litecointools.com",
            "seed-b.litecoin.loshan.co.uk",
            "dnsseed-testnet.thrasher.io"
    };

WalletCoinsReceivedEventListener.onCoinsReceived() not receiving events

has anyone else experienced this and have a solution? i have an identical implementation that works fine using bitcoinj/network.

deserializing error

I am trying to develop a wallet application using liteconj library.
When the wallet starts syncing it immediately throws the below error.

Incomplete Method

Please complete this, this program is invaluable to crypto currency and will revolutionize cryptocurrency usage. I believe LegacyAddress.fromKey is an incomplete method the outPutScriptType is added as a parameter but is not updated across the application. Please do this if you can. It will be of great help.

error Context does not match implicit network params

hi when I use your library with bitcoinJ for create lite coin and bitcoin wallet together, I have error error Context does not match implicit network params and Duplicate class org.bitcoin.NativeSecp256k1 found in modules bitcoinj-core-0.16.2 (org.bitcoinj:bitcoinj-core:0.16.2) and litecoinj-0.3.0 (com.github.pokkst:litecoinj:0.3.0)
. how to fix that ?
my example:

val params = MainNetParams.get()
val seed = DeterministicSeed(mnemonic, null, "", System.currentTimeMillis() / 1000)
val wallet = Wallet.fromSeed(params, seed, Script.ScriptType.P2WPKH)

// with your dependency
val params1 =MainNetParams.get()
val seed1 = DeterministicSeed(mnemonic, null, "", System.currentTimeMillis() / 1000)
val wallet1 = Wallet.fromSeed(params1, seed1, Script.ScriptType.P2WPKH)

here I receive this error.
