Different types of ERC20 Tokens

This is an amazing repository. The explanation is very lucid. But I got stuck at some place. I'm getting an error when I called a contract method "transferFrom" from user's address to send tokens to another user. I'm keep getting transaction exception. I'm using web3j wallet in android to do all the transactions. I can read balance, get approved limit but can't called transferFrom or mint functions. I keep getting TransactionException without any cause. Please help me resolve this issue.
