Variables not declared at companion/MainActivity.java

master branch has a build issue trying to build *niap-cc/Permissions/Companion* app:
```
> Task :app:compileDebugJavaWithJavac
security-certification-resources/niap-cc/Permissions/Companion/app/src/main/java/com/android/certifications/niap/permissions/companion/MainActivity.java:158: error: cannot find symbol
logdebug("DeviceConfig.setProperty failed.(" + a + "," + b + "," + value + ")",e);
^
symbol: variable a
location: class MainActivity
security-certification-resources/niap-cc/Permissions/Companion/app/src/main/java/com/android/certifications/niap/permissions/companion/MainActivity.java:158: error: cannot find symbol
logdebug("DeviceConfig.setProperty failed.(" + a + "," + b + "," + value + ")",e);
^
symbol: variable b
location: class MainActivity

Note: security-certification-resources/niap-cc/Permissions/Companion/app/src/main/java/com/android/certifications/niap/permissions/companion/MainActivity.java uses or overrides a deprecated API.
Note: Recompile with -Xlint:deprecation for details.
2 errors
```

Open security-certification-resources/niap-cc/Permissions/Companion/app/src/main/java/com/android/certifications/niap/permissions/companion/MainActivity.java around line 158 and inspect the DeviceConfig.setProperty failure logging and its surrounding declarations. Rebuild the Companion app to verify that the undeclared-variable errors are resolved and compilation completes successfully.
