Bad URI format

Error message

Bad URI format

What it means

Generic guard in parseExportUri(String): thrown when Uri.parse(s) returns null for the given export URI string, meaning the input could not be parsed as a URI at all. It fires on syntactically invalid or empty strings passed to vault export/import handling before any content is inspected.

Solutions

1. Verify the string is a complete export URI with the expected scheme before calling parseExportUri
2. Catch GoogleAuthInfoException and prompt the user to re-scan/re-share the export
3. Check the intent/clipboard source isn't returning empty or transformed text

Example fix

// before
GoogleAuthInfo.Export export = GoogleAuthInfo.parseExportUri(data);
// after
if (data != null && data.contains("://")) {
    GoogleAuthInfo.Export export = GoogleAuthInfo.parseExportUri(data);
} else {
    throw new GoogleAuthInfoException(null, "Invalid export URI");
}

if (s == null || !s.contains("://")) throw new IllegalArgumentException("not a URI");

try { GoogleAuthInfo.Export e = GoogleAuthInfo.parseExportUri(s); } catch (GoogleAuthInfoException ex) { showInvalidExportError(); }

When it happens

Trigger: Calling parseExportUri(s) with a null or unparseable string s.

Common situations: Passing a raw JSON/text export instead of an aegis:// (otpauth-migration style) URI, or a truncated string from an intent/clipboard read.
