Hey there!

I tried upgrading to version 7.0.0 and got the following error during build

[...]/node_modules/react-native-keychain/android/src/main/java/com/oblador/keychain/cipherStorage/CipherStorageKeystoreAESCBC.java:37: error: com.oblador.keychain.cipherStorage.CipherStorageKeystoreAESCBC is not abstract and does not override abstract method getDefaultAliasServiceName() in com.oblador.keychain.cipherStorage.CipherStorage

Delete the file node_modules/react-native-keychain/android/src/main/java/com/oblador/keychain/cipherStorage/CipherStorageKeystoreAESCBC.java. It appears to have been renamed with different casing CipherStorageKeystoreAesCbc.java somewhere along the line, and you have an old version.
