Invalid format: isGranted not found

Error message

Invalid format: isGranted not found

What it means

NotificationListenerRule's constructor reads the isGranted boolean from the flattened rule string. If the tokenizer is exhausted, it throws this IllegalArgumentException because a NOTIFICATION rule requires the isGranted field to know whether listener access is granted.

Solutions

  1. Append a "true"/"false" isGranted token to the flattened rule string
  2. Validate token count before constructing the rule
  3. Re-export rules from the current version to restore missing fields
  4. Try-catch the parse and skip malformed notification rules

Example fix

// before
new NotificationListenerRule(pkg, "cmp", new StringTokenizer("com.example\tcmp")); // throws
// after
new NotificationListenerRule(pkg, "cmp", new StringTokenizer("com.example\tcmp\ttrue"));
Defensive patterns

Strategy: try-catch

Validate before calling

String[] p = line.split("\t");
if (p.length < 3) throw new IllegalArgumentException("NOTIFICATION rule needs isGranted");
Boolean.parseBoolean(p[2]);

Type guard

boolean isParsableNotificationRule(String line) { String[] p = line.split("\t"); return p.length >= 3 && (p[2].equals("true") || p[2].equals("false")); }

Try / catch

try { new NotificationListenerRule(pkg, name, tokenizer); } catch (IllegalArgumentException e) { log.warn("Bad notification rule: " + line); }

Prevention

When it happens

Trigger: new NotificationListenerRule(packageName, name, tokenizer) called with no tokens remaining after the name, i.e. the flattened string stops at the component name.

Common situations: Truncated rules exports, manually trimmed lines, or parsing with a wrong delimiter so the boolean token merges or disappears.
