Question

There are many ways to start another activity.
The most of the overloading methods requires you to pass a context.

But when using componentName to launch an activity using

public Intent setComponent (ComponentName component)

and this constructor for ComponentName

ComponentName(String pkg, String cls)

You see above, I am able to launch an activity WITHOUT using any Context argument

But it must use some “context” somehow internally, am I right? If so, which context? Application one or the activity one?
Does this mean that every time I use this two methods (above), I do not need to worry about memory leak becuase I am not passing any context around??

Thanks

You don’t have to worry about memory leaks in either case, but it’s good that you’re keeping an eye on where you’re passing Context objects. Intent simply uses the Context parameter to look up your package name when you use the Intent(Context, Class) constructor or setClass(Context, Class) method. They’re just convenience methods.
