[core] Change which activity is launched by default from the smali debugger

[Auties00]

I'm trying to debug an Android app using the included smali debugger. When I launch the app, the debugger outputs: Breakpoint will set at com.whatsapp.settings.SettingsNotifications.onCreate(Landroid/os/Bundle;)V` Yet I want to launch another activity and set a breakpoint there, how can I do this? Also, can I set arbitrary breakpoints from the source code(i.e. at specific lines)?
