Question

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 ?

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.
