I am working with watching wallet and Offline wallet using bitcoinj, I created Watching Wallet using tpub key of Offline Wallet

I am receiving payment on watching wallet Fine, now I want to spend coins from watching wallet after Signing my transaction from offline wallet

What I am doing is creating rawTx from the Watching Wallet and then signing it with the private key from Offline Wallet but when I broadcast it, it throws an exception:

InsufficientMoneyException

But my wallet balance is 0.23389 BTC , its not spendable balance as my watching wallet shows

Wallet containing 0.23389 BTC (spendable: 0.00 BTC)

This is not spendable because we cannot spend coins from watching wallet unless you sign it with the corresponding private key

Below is my code: As i am trying to sign transaction from my offline wallet, so i can spend coins from watching wallet

For creating Raw Transaction from Watching Wallet

private void bla()
{
    Coin coin = Coin.parseCoin("0.01");
    Address address = Address.fromBase58(params, "n4oLPFUGvohSdDxvJS3amXvfE1GEdZBddd");
    Transaction tx = new Transaction(params);
    System.out.println("Raw TX: " + tx.toString());
    byte[] bytes = Script.createInputScript("5ff01d61e67c706cb79653aa1e7ad2c7254b841167e0a34055504c35c7240469".getBytes()); // tx hash 
    TransactionInput input = null;
    List<Transaction> list = kit.wallet().getTransactionsByTime();
    for(Transaction t: list)
    {
        input = t.getInput(0);
    }

    //Creates a scriptPubKey that encodes payment to the given address.
    Script scriptPubKey = ScriptBuilder.createOutputScript(address);
    // Signature Script
    Script scriptSig = input.getScriptSig();

    // Adding output that involves Amount and Script
    tx.addOutput(coin, scriptPubKey);
    System.out.println("Script pub key: " + scriptPubKey);

    //Adding input to the raw transaction
    tx.addInput(input);
    System.out.println("After adding inputs: " + tx.toString());
}

Signing Transaction from Offline Wallet Using Private Key

private String signTx()
{
    // TX Hash from Watching wallet
    String unSignHash = "f348ceadcb66e811799aa543107b63b9c92afebda5bc47d11222ba218df6638f";
    // Signing Hash with private key
    System.out.println("Signed Hash from prv key: " + DatatypeConverter.printHexBinary(prvKey().sign(Sha256Hash.wrap(unSignHash)).encodeToDER()));
}

Then I have added one more input in raw transaction

 input.setScriptSig(ScriptBuilder.createInputScript(new TransactionSignature(OfflineWallet.prvKey().sign(hash), Transaction.SigHash.ALL, true), OfflineWallet.ecKey()));
        tx.addInput(input);

After that my raw transaction looks like this

Then i am broadcasting it using

try
        {
            kit.wallet().sendCoins(SendRequest.forTx(tx));
        }
        catch (InsufficientMoneyException e)
        {
            e.printStackTrace();
        }

I am getting the exception here.

I don't know what I am doing wrong here, as I think my tx hash is just fine, all I have to do is broadcast the transaction into the network from watching wallet, which I am also doing but cannot succeed. I would really appreciate if someone helps me to find my mistake and broadcasting the signed transaction from watching wallet.
