Invalid key

Error message

Invalid key ${key}

What it means

LastUpdateOption.test() switches over the configured key (all/before/after); any other key hits the default branch and throws UnsupportedOperationException. Since setKeyValue() validates keys against the key map, this error means the key state and the test() switch are out of sync.

Solutions

1. Add a case for the key in LastUpdateOption.test()'s switch.
2. Set keys only via setKeyValue() for validation.
3. Keep the key map and test() switch synchronized.

Example fix

// before
case "after":
    return result.setMatched(installed && info.getLastUpdateTime() >= longValue);
default:
    throw new UnsupportedOperationException("Invalid key " + key);
// after
case "after":
    return result.setMatched(installed && info.getLastUpdateTime() >= longValue);
case "new_key":
    return result.setMatched(/* logic */);
default:
    throw new UnsupportedOperationException("Invalid key " + key);

if (!option.getKeysWithType().containsKey(option.getKey())) {
    throw new IllegalStateException("Unrecognized key: " + option.getKey());
}

try {
    result = option.test(info, result);
} catch (UnsupportedOperationException e) {
    Log.w(TAG, "Filter option key not supported", e);
    result.setMatched(false);
}

When it happens

Trigger: A key in LastUpdateOption's key map without a case in test()'s switch; the protected `key` field mutated directly; stale keys from hand-built Parcels or reflection.

Common situations: Adding a new time-comparison key without updating test(); forked builds with extra keys; deserialization of crafted filter data.

Understand the failure class

Background: UnsupportedOperationException and "is not supported" errors: when a library deliberately refuses a call — this error's family across 30 libraries.
