Counter is not an integer.

Error message

Counter is not an integer.

What it means

For HOTP entries, EditEntryActivity.parseEntry() reads the counter from the period/counter field with Long.parseLong and wraps NumberFormatException in a ParseException. The HOTP counter must be a 64-bit integer, so empty or non-numeric input is rejected before constructing HotpInfo.

Solutions

1. Enter a plain integer counter (e.g. 0) in the period/counter field before saving
2. Retype the value to remove whitespace or separators like commas
3. Use a value within signed 64-bit range (-9223372036854775808 to 9223372036854775807)

Example fix

// before
counterField.setText("1,000");
// after
counterField.setText("1000");

String counter = _textPeriodCounter.getText().toString().trim();
if (!counter.matches("-?\\d+")) {
    _textPeriodCounterLayout.setError("HOTP counter must be an integer");
    return;
}

try {
    saveEntry();
} catch (ParseException e) {
    if ("Counter is not an integer.".equals(e.getMessage())) {
        _textPeriodCounterLayout.setError("Enter an integer counter");
    }
}

When it happens

Trigger: Saving an HOTP entry while the counter field is empty, contains letters/decimals, or exceeds Long range; Long.parseLong throws NumberFormatException.

Common situations: Switching an entry from TOTP to HOTP without setting a counter, or pasting a counter value with formatting such as '1,000' or '0x1F'.
