If you encounter an error that says ‘error: cannot find symbol’ or ‘Cannot resolve symbol makeText’, there are multiple possible causes. First, ensure that you have entered all the parameters correctly.
The Toast makeText function requires the following:
(Context, “String to display”, duration of Toast). Duration is an integer.
You can declare a context above using the following line:
Context examplecontext = getApplicationContext;
In your function, ensure that you are not using the ‘new’ operator to declare your Toast object.
Toast exampleToast = Toast.makeText(examplecontext, “Here’s your Toast message!”, Toast.LENGTH_LONG);
What not to do:
Toast exampleToast = new Toast.makeText(examplecontext, “Here’s your Toast message!”, Toast.LENGTH_LONG);
