Unsupported OtpInfo type

Error message

Unsupported OtpInfo type: %s

What it means

getUri builds an otpauth:// URI from an OtpInfo; it only knows TotpInfo and HotpInfo subclasses. If _info is neither (a custom or future OtpInfo subclass), a RuntimeException is thrown because there is no standard URI encoding for it. This is an internal invariant rather than bad user input.

Solutions

1. Only pass TotpInfo/HotpInfo entries to getUri; filter or convert other types first
2. Skip unsupported entry types during export instead of failing the whole batch
3. Extend the if/else chain to handle the custom OtpInfo type or subclass TotpInfo/HotpInfo

Example fix

// before
GoogleAuthInfo.getUri(entry); // entry.getInfo() is a custom MotpInfo
// after
if (entry.getInfo() instanceof TotpInfo || entry.getInfo() instanceof HotpInfo) {
    GoogleAuthInfo.getUri(entry);
} else {
    continue; // skip unsupported type
}

if (!(info instanceof TotpInfo) && !(info instanceof HotpInfo)) {
    throw new IllegalArgumentException("Only TOTP/HOTP entries can be exported");
}

boolean exportable(VaultEntry e) {
    return e.getInfo() instanceof TotpInfo || e.getInfo() instanceof HotpInfo;
}

try {
    uri = GoogleAuthInfo.getUri(entry);
} catch (RuntimeException e) {
    Log.w(TAG, "Skipping non-exportable entry: " + e.getMessage());
}

When it happens

Trigger: Calling GoogleAuthInfo.getUri (directly or via export/exportGoogleUris) on an entry whose OtpInfo is neither TotpInfo nor HotpInfo.

Common situations: Custom OtpInfo subclasses added by forks (e.g. Steam or Yandex types) passed into the Google export path, or future info types from library updates not yet handled here.
