According to this answer or the android's documentation there is several ways to get the Context in an app and pass it to an other class/method/whateveruneed.
Let's say I'm in the Foo Activity and in need to pass the context to Bar's constructor.
Bar bar = new Bar(Foo.this);
Bar bar2 = new Bar(this); //same as first i guess
Bar bar3 = new Bar(getApplicationContext());
Bar bar4 = new Bar(getBaseContext());
Bar bar5 = new Bar(MyApp.getContext); // get context statically
Taking into account of memory leaks, speed , general performance , what will be the better way between all those possibilities ?

Application Context : We can access it using getApplicationContext(). It returns the context for the entire application (the process inside which all activity is running). If somewhere in the activity we need a context which is tied to the whole application lifecycle and not just the activity.
Application Context This Context is tied to the Lifecycle of an Application. Mainly it is an instance that is a singleton and can be accessed via getApplicationContext().
Kubectl current-context command shows the current context of kubectl. When you enter the 'kubectl config current-context' in the virtual machine environment, the following output will be displayed. The 'kubectl config use-context cluster-name' command is used to set the default context to the given cluster name.
Definition. it's the context of current state of the application/object. It lets newly-created objects understand what has been going on. Typically, you call it to get information regarding another part of your program (activity and package/application).
You should check out this question - which basicly covers the same as yours.
Also the Developer Docs on Avoiding memory leaks gives you a decent explanation of some situtations in which various of the methods are reasonable to use.

I think that this post will provide you enough information. Look at the first response.
