store last wallet balance in app

[DanielPollithy]

If a device is not connected to the internet we can't show the current account balance. I guess we should store this (together with the last index) in the EncryptedSharedPreferences

What do you think, Toby?

@DanielPollithy Yeah, that makes sense. I can put an output message that the balance may not be up to date.

@tobywoerthle Thanks! The thing is that I want to check the balance of the user before starting a hotspot...

@DanielPollithy Use below function to retrieve shared pref for balance + balance update date time

ex.

String balance = getSharedPrefKey("balance");
String balanceUpdateDateTime = getSharedPrefKey("balanceDateUpdate");

private String getSharedPrefKey(String key) {
        SharedPreferences sharedPref = context.getSharedPreferences(prefFile, Context.MODE_PRIVATE);
        String defaultValue = "0";
        String storedBalance = sharedPref.getString(key,defaultValue);
        return storedBalance;
    }

I'll update this as soon as the app starts.

The balance will be updated when app starts and gets past seed login screen: 3e96e2fba6850cfc7c2fa65ef47c88fb80a0faef
