android - How do I make a toast from a non activity class?

I have a class that I am using to get GPS data within my activity. In the constructor I pass it the activity's context:

gpsFetcher = new GPSFetcher(this);

and in the gpsFetcher class I have:

this.context = c.getApplicationContext();

OR just

this.context = c;

and then I call the toast with:

Toast.makeText(context, "sometext", Toast.LENGTH_LONG);

But it never shows up... Is there something I'm missing? Is it possible?

Thanks!

Are you forgetting Toast#show?

Toast toast = Toast.makeText(context, "sometext", Toast.LENGTH_LONG);
toast.show();
