SecurityException

[b5-3]

Do you know why this security exception occur? I am accessing it in my own process.

I am keeping tray provider like below for proguard obfuscation

-keep class net.grandcentrix.tray.provider.** {*;}

Does it happen only for release builds? how often does it happen? Always? When are you querying the provider? Right after the app has started?

[b5-3]

When I receive ACTION_MY_PACKAGE_REPLACED, I read a preference key like below in onReceive() means, process has been killed for package install and then created by ACTION_MY_PACKAGE_REPLACED.

• SETUP_WIZARD : module name

• 1 : version

  Preference oldPreference = new Preference("SETUP_WIZARD", 1);
  String oldWay = null;
  try {
      oldWay = oldPreference.getString(Preference.KEY_SOFTWARE_UPDATE);
  } catch (ItemNotFoundException e) {
      LogUtil.w(TAG, "KEY_SOFTWARE_UPDATE not found");
  }

it's occurred frequently. not always I have observed this in release build only now, but I'm not sure that debug build has no same issue.

Should I create a tray preference instance in Application class?
