Methods on Android are failing

[BlakeKaufman]

I have installed the LWK into a bare react-native test environment You can reproduce the issue here: https://github.com/BlakeKaufman/lwkTest

Everything seems to be working fine on IOS, however, Android is returning errors when calling methods.

When calling wollet.getAddress(); I am getting an error saying: LwkRnModule.getAddress got 4 arguments, expected 3. This error is crashing the app.

When calling wollet.getTransactions() I am getting a warning saying: java.lang.illegalArgumentException: Could not convert class lwk.Txid. Although it is just a warning nothing is returned.

when calling wollet.getBalance() I am getting a warning saying: java.lang.RuntimeException: Cannot convert argument of type class koltin.collections.builders.MapBuilder. Although this is just a warning, nothing is returned.

The code I am running is

import {Wollet, Client, Signer, Network, TxBuilder} from 'lwk-rn';

async function connectToLWK() {
  const mnemonic =
    'abandon abandon abandon abandon abandon abandon abandon abandon abandon abandon abandon about';
  console.log(mnemonic);
  const network = Network.Testnet;
  const signer = await new Signer().create(mnemonic, network);
  const descriptor = await signer.wpkhSlip77Descriptor();
  console.log(await descriptor.asString());

  const wollet = await new Wollet().create(network, descriptor, null);
  const client = await new Client().defaultElectrumClient(network);
  const update = await client.fullScan(wollet);
  await wollet.applyUpdate(update);

  // const txs = await wollet.getTransactions();
  // // console.log('Get transactions');
  // console.log(txs);

  // const address = await wollet.getAddress();
  // console.log('Get address');
  // console.log(address);

  const balance = await wollet.getBalance();
  // console.log('Get balance');
  console.log(balance[liquidTestnet]);

  return;
  const out_address =
    'tlq1qqfkh3gtdtfw0uqcx8d0r7w3zh65tenu63qg394hwyed0lpey4hp5e0gztg6ay3nvz2k6d44quhz634s8weg6jt3xsz0h3jems';
  const satoshis = 1000;
  const fee_rate = 100; // this seems like absolute fees
  const builder = await new TxBuilder().create(network);
  await builder.addLbtcRecipient(out_address, satoshis);
  await builder.feeRate(fee_rate);
  let pset = await builder.finish(wollet);
  let signed_pset = await signer.sign(pset);
  let finalized_pset = await wollet.finalize(signed_pset);
  const tx = await finalized_pset.extractTx();
  await client.broadcast(tx);
  console.log('BROADCASTED TX!\nTXID: {:?}', (await tx.txId()).toString());
}

Hi @BlakeKaufman , there was some incompatibility in kotlin types with react native. Fix android bindings and more related stuff in https://github.com/lvaccaro/lwk-rn/pull/11 . Could you check again your code?

I could make a new tag and publish a npm release, if it makes your tests easier. thanks

[BlakeKaufman]

Ya, could you make another tag on npm? It will ensure I don't add any user error when copying changes.

Merged #11 and tag new release 0.1.1 available at https://www.npmjs.com/package/lwk-rn
