Invalid attribute " + name + ": " + e

Error message

Invalid attribute " + name + ": " + e

What it means

Attribute.getValueDouble() throws XmlPullParserException when the attribute's string representation cannot be parsed as a double (stored type TYPE_STRING/TYPE_STRING_INTERNED). The message embeds the attribute name and the underlying NumberFormatException.

Solutions

1. Fix the producer to write valid double literals (Locale-invariant formatting, e.g. Double.toString).
2. Pre-validate the string with Double.parseDouble in a try-catch before parsing, or use a fallback default.
3. Use the getter matching the attribute's actual type (TYPE_DOUBLE attributes parse directly and won't take this branch).
4. Catch XmlPullParserException and treat the attribute as missing/invalid.

Example fix

// before
double d = attr.getValueDouble(); // "1,5" throws
// after
double d;
try { d = attr.getValueDouble(); }
catch (XmlPullParserException e) { d = 0.0; /* or log & recover */ }

String s = attr.getValueString();
boolean parseable = s != null;
if (parseable) {
    try { Double.parseDouble(s); } catch (NumberFormatException e) { parseable = false; }
}

try {
    d = attr.getValueDouble();
} catch (XmlPullParserException e) {
    d = DEFAULT_DOUBLE; // log e.getMessage() for diagnostics
}

When it happens

Trigger: Calling getValueDouble() on a string-typed attribute whose value is not a valid double literal, e.g. "abc", "1,5", or an empty string.

Common situations: Binary XML written by another tool/locale where numbers were serialized with commas or units, or a schema change that stored a non-numeric string where a double was expected.
