Hello Everyone,

I am facing an issue while trying to run/build the android wallet source code in android studio. I downloaded the wallet source code from [https://github.com/blockchain-certificates/wallet-android](https://github.com/blockchain-certificates/wallet-android). I imported the code as gradle project and tried to run it, got the following error.  
Java Compiler : error: cannot find symbol method verifyIssuer(BlockCert,TxRecord); error: cannot find symbol method verifyBitcoinTransactionRecord(BlockCert) ![33%20PM](https://us1.discourse-cdn.com/flex016/uploads/blockcerts/original/1X/e8548ead98d4ed3c392b5f440b4dbefaf57f6dfb.png)

Also, tried running the build.sh file, and it got failed.

Kindly help me solve the issue.

Note: BTW, I am very new to Blockchain, Android & Java. So, kindly spare me if any.

Thanks,  
Gowtham R
