Now receive coins working but send not working i.e tx hash show tx not found on blockchain.
Please check below log.

Can anyone help to find issue ?

I would start with fixing Performing thread fixup: you are accessing bitcoinj via a thread that has not had any context set on it. at the top. bitcoinj needs the Context set up so it knows what network parameters (i.e. Dogecoin rather than Bitcoin to use).

CATE for example handles this by creating a context at the start ( https://github.com/rnicoll/cate/blob/master/src/main/java/org/libdohj/cate/controller/MainController.java#L186 ) and using a custom thread factory to propagate the context onto every thread it creates: https://github.com/rnicoll/cate/blob/master/src/main/java/org/libdohj/cate/util/NetworkThreadFactory.java#L54

Hi,
I have mentioned network param via wallet init code is as below,
WalletAppKit kit = new WalletAppKit(DogecoinTestNet3Params.get(), new File("/home/ep"),"doge-testnet");

Below can be reason ??

2018-08-02 11:40:52,622 INFO [org.bitcoinj.core.TransactionBroadcast] (EJB default - 36) Waiting for 10 peers required for broadcast, we have 8 ...

For testnet only one dns seed mentioned i.e "testseed.jrn.me.uk".
Do we have more ?

[kunalransing]

I guess issue solved. In code for testnet dns seeds contains only one entry. For broadcast 10 peers connection required & I had only 8 connected. Now I added few more dns seeds then peers connection crossed 10 & it broadcasts txs.
Thanks.
