title: How to create bitcoin wallet from mnemonics using bitcoinj (walletappkit) in android
body: <p>I am creating a wallet from mnemonics,for ethereum i have used web3j library for generating mnemonics,address and its private key and now for bitcoin i want to use the same generated mnemonics to generate bitcoin address and its private key for bitcoin i am using Bitcoinj library but not able to get its address and key.</p>
  <p>I also tried Walletappkit but its generating address without getting mnemonics so is there any way of using mnemonics in Walletappkit so i can get bitcoin address and sync the bitcoin chain for transactions.
  Also is there any way of using walletappkit without syncing and gets bitcoin detail like its balance and transaction info.</p>
  <p>Below is the code how I created ethereum wallet and its mnemonic key using web3j and bitcoinj.</p>
  <pre><code>val wallet = WalletUtils.generateBip39Wallet(&quot;&quot;, File(path))
              val mnemonics = wallet.mnemonic
              //  bitcoinj
              var seed = DeterministicSeed(wallet.mnemonic, null, &quot;&quot;, 1409478661L)
              val chain = DeterministicKeyChain.builder().seed(seed).build()
              val keyPath = HDUtils.parsePath(&quot;M/44H/60H/0H/0/0&quot;)
              val key = chain.getKeyByPath(keyPath, true)
              val privKey = key.privKey
  
               
              // Web3j
              val credentials = Credentials.create(privKey.toString(16))
              val eth_address = credentials.address
  </code></pre>
