Toast not showing on progressUpdate in android 6 when using getApplicationContext() as context

Question

I´m trying to show a Toast on ProgressUpdate() method. Works well on Android 4,5 but the toast is not shown on android 6 and no exceptions are thrown.

Here is my method:

@Override
    protected void onProgressUpdate(String... values) { 
    super.onProgressUpdate(values);
    Toast.makeText(getApplicationContext(), values[0],     Toast.LENGTH_SHORT).show();
    }

If I replace getApplicationContext() with getBaseContext(), the Toast works as expected.

It does not work if I use MainActivity.this as context

Is it correct to use getBaseContext() ? Why works with getApplicationContext() on android 4,5 and not on 6?

I'm not sure what happened when they made the Android 6.0 update, but they must have wrapped some contexts, or something like that. Here's the difference between those two methods: Difference between getContext() , getApplicationContext() , getBaseContext() and "this"

Activity.getApplicationContext(): Returns the context for the entire application (the process all the Activities are running inside of). Use this instead of the current Activity context if you need a context tied to the lifecycle of the entire application, not just the current Activity.

ContextWrapper.getBaseContext(): If you need access to a Context from within another context, you use a ContextWrapper. The Context referred to from inside that ContextWrapper is accessed via getBaseContext().
