Bad component name

Error message

Bad component name: ${rawValue}

What it means

IntentCompat.parseExtraValue() reconstructs typed Intent extras from a flattened string form. For TYPE_COMPONENT_NAME it calls ComponentName.unflattenFromString(rawValue); a null result means the string is not of the form 'package/class', so it throws IllegalArgumentException('Bad component name: ...').

Solutions

1. Format the value as 'full.package.name/fully.qualified.ClassName', e.g. com.example/.MainActivity
2. Use ComponentName.flattenToString() on the source side so the value round-trips correctly
3. Validate with ComponentName.unflattenFromString() != null before setting the extra

Example fix

// before
"com.example.MainActivity" // no package/class separator
// after
"com.example/com.example.MainActivity"

if (ComponentName.unflattenFromString(rawValue) == null) {
    throw new IllegalArgumentException("Not a flattenToString() component: " + rawValue);
}

try {
    Object v = IntentCompat.parseExtraValue(type, rawValue);
} catch (IllegalArgumentException e) {
    Log.w(TAG, "Malformed extra value", e);
}

When it happens

Trigger: Passing a TYPE_COMPONENT_NAME extra whose raw value lacks the required 'pkg/cls' flattening — e.g. missing slash, empty class, or malformed package.

Common situations: Hand-crafting or editing intercepted-intent strings; copying intent URIs between apps with typos; automation scripts producing invalid component strings.
