Digits is not an integer.

Error message

Digits is not an integer.

What it means

EditEntryActivity.parseEntry() parses the digits field with Integer.parseInt and wraps NumberFormatException in a ParseException. Aegis throws this when the number-of-digits field for the OTP code is empty or non-numeric, because the code length must be an integer to configure the OtpInfo.

Solutions

1. Enter a plain integer (commonly 6 or 8) in the Digits field before saving
2. Retype the value to remove stray whitespace or hidden characters
3. Restore the provider's documented code length (usually 6)

Example fix

// before
digitsField.setText("6.0");
// after
digitsField.setText("6");

String digits = _textDigits.getText().toString().trim();
if (!digits.matches("\\d+")) {
    _textDigitsLayout.setError("Enter a whole number");
    return;
}

try {
    saveEntry();
} catch (ParseException e) {
    if ("Digits is not an integer.".equals(e.getMessage())) {
        _textDigitsLayout.setError("Digits must be a whole number");
    }
}

When it happens

Trigger: Saving an entry while the 'Digits' text field is empty, contains letters, decimal values like '6.0', or whitespace; Integer.parseInt throws NumberFormatException.

Common situations: Users experimenting with advanced settings clearing the digits field, or pasting values such as 'six' or '6 ' into it.
