Sorry, there are three separate applications. One is my Photo Editor
application. The other two applications are the launcher applications,
they emit  android.intent.action.EDIT intent to launch my Photo Editor
application.

The Photo Editor application contains my photo editor activity which
uses a singleton class. And that singleton class instance is used by
the two instance of my photo editor activity due to  other two
applications both emit  android.intent.action.EDIT intent.

What do you mean use the Application context to synchronize access to
the singleton? How should I use it?

Thanks!
