Thank you Jonald for the great Bitcoin Cash Wallet!
Great app, but doesn't work after last update. At least on Huawei Mate 8.
3.1.3 Fixes security flaws in prior versions. A JSONRPC security hole was previously discovered that affects all Electrum forks. This has been fully patched in this version. If you were running a prior version as an online wallet, you should consider the wallet compromised and create a fresh wallet with version 3.1.2 or better.
