Invalid key

Error message

Invalid key ${key}

What it means

InstalledOption.test() switches over the configured key (all/installed/not_installed/installed_before/installed_after); any other key hits the default branch and throws UnsupportedOperationException. The key should have been validated by setKeyValue(), so this means the key state is inconsistent with the class's switch.

Solutions

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

Example fix

// before
case "installed_after":
    return result.setMatched(installed && info.getFirstInstallTime() >= longValue);
default:
    throw new UnsupportedOperationException("Invalid key " + key);
// after
case "installed_after":
    return result.setMatched(installed && info.getFirstInstallTime() >= 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 present in InstalledOption's key map but missing a case in test()'s switch; direct modification of the protected `key` field; stale keys from hand-built Parcels or reflection.

Common situations: Adding a new install-related key without updating test(); forked builds with extra keys; deserialization of crafted 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.
