manufacturer is absent in result.info.

Error message

manufacturer is absent in result.info.

What it means

Same result.info parsing in CLIMain.doAnalyze: the 'manufacturer' key must be present so the analyzer can report which device leaked the activity. A missing manufacturer line aborts analysis with IllegalStateException after sdkVersion has been validated.

Solutions

  1. Regenerate the result bundle with a matching Matrix version so result.info includes manufacturer=<device maker>
  2. Manually add 'manufacturer=<value>' to result.info inside the zip
  3. Check for typos/key-case mismatches in result.info

Example fix

// before (result.info)
sdkVersion=33
// after (result.info)
sdkVersion=33
manufacturer=Google
Defensive patterns

Strategy: validation

Validate before calling

if (!info.containsKey("manufacturer")) throw new IllegalArgumentException("result.info missing manufacturer");

Type guard

null

Try / catch

try { doAnalyze(args); } catch (IllegalStateException e) { System.err.println("Invalid result bundle: " + e.getMessage()); System.exit(1); }

Prevention

When it happens

Trigger: Running the analyzer on a result zip whose result.info does not include the 'manufacturer' key (missing, misspelled, or empty line).

Common situations: Bundles edited by hand; older or third-party producers of the hprof report zip that omit manufacturer; copying a result.info template that drops the field.
