title: What is the better way to get Context?
body: <p>According to <a href="https://stackoverflow.com/a/3572553/393984">this answer</a> 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.</p>
  
  <p>Let's say I'm in the Foo Activity and in need to pass the context to Bar's constructor.</p>
  
  <pre><code>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 
  </code></pre>
  
  <p>Taking into account of memory leaks, speed , general performance , what will be the better way between all those possibilities ? </p>
