- Method Detail
  - onCoinsReceived
```
void onCoinsReceived(Wallet wallet,
                     Transaction tx,
                     Coin prevBalance,
                     Coin newBalance)
```
    This is called when a transaction is seen that sends coins to this wallet, either because it was broadcast across the network or because a block was received. If a transaction is seen when it was broadcast, onCoinsReceived won't be called again when a block containing it is received. If you want to know when such a transaction receives its first confirmation, register a TransactionConfidence event listener using the object retrieved via Transaction.getConfidence(). It's safe to modify the wallet in this callback, for example, by spending the transaction just received.
    
    Parameters:
    
    wallet - The wallet object that received the coins
    
    tx - The transaction which sent us the coins.
    
    prevBalance - Balance before the coins were received.
    
    newBalance - Current balance of the wallet. This is the 'estimated' balance.
