Android : Can App's Main Activity Be Bypassed On Launch?

Are there any scenarios on Android where a process can be instantiated (classes loaded, etc.) and a non-main activity launched without going through the main activity? Background: my app has a single main activity (android:name="android.intent.action.MAIN" and android:name="android.intent.category.LAUNCHER"), some secondary activities, and a preferences class providing static methods meant to be called from anywhere. These static methods' implementations require a Context, and so the class has a static Context member s_context; the static methods assert that s_context is non-null before using it. The very first thing I do in my main activity's onCreate() method is pass getApplicationContext() into the preferences class so it can set s_context.
