Your code is incomplete. You're not showing where the wallet is set up. Perhaps the bug is there.
BTW that code seems quite old - IRC hasn't been used for a long time.
following is the whole code:
public static void main(String[] args) throws AddressFormatException, IOException {
boolean testNet = args.length > 0 && args[0].equalsIgnoreCase("testnet");
final NetworkParameters params = testNet ? NetworkParameters.testNet() : NetworkParameters.prodNet();
Wallet wallet=new Wallet(params);
byte bytes[]=Utils.parseAsHexOrBase58("500E3714FA3FD232C3885BEA78FB9418054AE4BB7000E589B1CF6CFD36598F6A");
byte bytes1[]=Utils.parseAsHexOrBase58("A65DE055E85412BF6EC98B3459E7773F1102504504F077C3E9DD212580C26A57");
byte bytes2[]=Utils.parseAsHexOrBase58("21");
ECKey key=new ECKey(new BigInteger(1,bytes),null,false);
ECKey key1=new ECKey(new BigInteger(1,bytes1),null,true);
ECKey key2=new ECKey(new BigInteger(1,bytes2));
wallet.addKey(key);
wallet.addKey(key1);
wallet.addKey(key2);
try
{
System.out.println("Reading block store from disk");
File file=new File("temp.blockchain");
BlockStore blockStore = new BoundedOverheadBlockStore(params, file);
BlockChain chain = new BlockChain(params, wallet, blockStore);
System.out.println("Connecting ...");
PeerGroup peerGroup = new PeerGroup(params, chain);
peerGroup.setUserAgent("PingService", "1.0");
if (testNet) {
peerGroup.addPeerDiscovery(new IrcDiscovery("#bitcoinTEST3"));
} else {
peerGroup.addPeerDiscovery(new DnsDiscovery(params));
}
peerGroup.addWallet(wallet);
peerGroup.startAndWait();
peerGroup.downloadBlockChain();
System.out.println("You have " + Utils.bitcoinValueToFriendlyString(wallet.getBalance()) + " BTC");
}
catch (Exception e)
{
e.printStackTrace();
}
}for the first time it works ok. and show me the balance correctly . and under my project there is a new "temp.blockchain" file;
and then I shut down the app and run again ,it only shows me "0.00 BTC" with the same wallet ,same Ekeys.
and there is no error reported to me .
and then I deleted the temp.blockchain ,and run again ,everything goes ok.
So It seems I find the solution . BUT ,everytime the app tries to download the new blockchain , it takes me nearly half an hour（about 25M）
I tried to change the BoundedOverheadBlockStore to DiskBlockStore ,but I don't know where to download it .
