Android Studio cannot resolve method getBaseContext(), but it used to work

In my app I'm using Toasts as 

Toast.makeText(getBaseContext(), "Updating...", Toast.LENGTH_SHORT).show();

Which has worked fine until now. Now I all of a sudden get the following error for all of my toasts.

Cannot resolve method getBaseContext()

I found this question on here, which was solved by having the class extend ActionBarActivity. The class my toasts are in is the MainActivity.java and extends AppCompatActivity, and implements View.OnTouchListener. I doubt it has anything to do with this, since the class is extending an Activity anyhow.

I have tried cleaning and rebuilding the project several times. Also, I've done an "Invalidate Caches / Restart..."

Updating Android Studio did the trick. Sometimes, the solution is so simple.

Best practic for using Toast is create a method in class Utils.class with context

public class Utils {
 public static void showToast(Context context, String msg) {
        Toast.makeText(context, msg, Toast.LENGTH_SHORT).show();
    }
}

Then u can call this like:

 Utils.showToast(context, context.getString(R.string.cannot_connect));

i can update my question if u say that u use fragment or activity for calling Toast method.

on the activity just call this, if not help try with getApplicationContext

in fragments create something like:

private Context context;
    private Activity activity;

@Override
    public void onAttach(Activity activity) {
        super.onAttach(activity);
        this.activity = activity;
        context = activity.getApplicationContext();
    }

But if u not need activity in fragment use:

@Override
    public void onAttach(Context context) {
        super.onAttach(context);
        context = getApplicationContext();
    }

also try make context

private Context context

and on OnCreate

context = getApplicationContext();

Try to use this. It worked perfectly for me

Toast.makeText(getApplicationContext(), "Updating...", Toast.LENGTH_SHORT).show();

Try this code too.... Sometimes it would work

Toast.makeText(this, "Updating...", Toast.LENGTH_SHORT).show();

try this

Toast.makeText(YourClass.this.getBaseContext(), "Updating...", Toast.LENGTH_SHORT).show();
