The blockchain download

[leandrogomesmachado]

Hello, I am with a little trouble with the J server and Android Wallet, did you get a problem to download the blockchain properly?
I am working hard here but I can't figure where is the problem, the Android Wallet download the chain only to 12 or 13 hours behind the main chain, located at block explorer.
I found that are with URL exception with ?package=kobocoin_android_wallet here but I update and I am testing... I think that will not work good, but I don't know where I need to change.

Matthew, I know that you are very busy guy, but please can you give me help? I need finish this two wallets, I will send now to github and will send to you a pushback from the code. Back soon

Actual problem is this, only show this blocks, the wallet stuck and not download new blocks. what I need to do?

After debugging I get this:

I know that is a checksig problem, but I don't know how to solve it.

[HashEngineering]

This log doesn't contain enough information. There is a VerificationException that is triggered.
com.bushstar.htmlcoinj.core.VerificationException: Could not verify block 00000000c06639b2ad26da1c35c99c1bc63fe8bf5ab2294c9c104395cbe5361a
at com.bushstar.htmlcoinj.core.AbstractBlockChain.add(AbstractBlockChain.java:268) ~[na:0.0]
...
Caused by: com.bushstar.h

The exception is thrown when the block is added to the blockchain because of some error, which could be the proof of work check, difficulty bits don't match or other reasons. The line that says "Caused by: com.bustar.h" needs to be expanded to see where the VerificationException is thrown.

The difficulty target does not match nbits I think, the link for pastebin gave the full log with full informations.
I will upload today the updated code of htmlcoinj to see. Thank you
