Cannot find symbol class MakeText error

Question

Here's how I implement Toast:

    if ((name == "") || (pass == "")){
        Toast invalidLoginToast = new Toast.makeText(this, "aaa", 3).show();
    } else {
        Intent intent = new Intent (this, AnnouncementsActivity.class);
        String deviceId = Secure.getString(this.getContentResolver(), Secure.ANDROID_ID);
        intent.putExtra("NAME", name);
        intent.putExtra("ID", deviceId);
        startActivity(intent);
    }

But I get the error

Error:(34, 48) error: cannot find symbol class makeText

Neccessary imports are already made. Am I sending wrong parameters into the method?

define toast like `Toast invalidLoginToast = Toast.makeText(this, "aaa", 3).show();` and remove `new` keyword — Shreeya Chhatrala, Jul 13 '17 at 07:16

Instantiate a Toast object with one of the makeText() methods. This method takes three parameters: the application Context, the text message, and the duration for the toast. It returns a properly initialized Toast object. You can display the toast notification with show();

Toast.makeText(context, text, duration)

Read official guideline about Toast .

  Toast.makeText(CurrentActivityName.this,"aaa",Toast.LENGTH_SHORT).show();

This line is wrong,

Toast invalidLoginToast = new Toast.makeText(this, "aaa", 3).show();

Replace it with

Toast.makeText(this, "aaa", 3).show();

Toast is having makeText method as static, and you can call it from the class name, don't call it the way you are calling it(i.e by new operator). For further info, please visit the official documentation

Toast.makeText(context, text, duration);

context

getApplicationContext() - Returns the context for all activities running in application.

getBaseContext() - If you want to access Context from another context within application you can access.

getContext() - Returns the context view only current running activity.

text

text - Return "STRING" , If not string you can use type cast. (string)num // type caste duration

duration

Toast.LENGTH_SHORT - Toast delay 2000 ms predefined

Toast.LENGTH_LONG - Toast delay 3500 ms predefined

milisecond - Toast delay user defined miliseconds (eg. 4000)

if ((name.equals("")) || (pass.equals(""))){
     Toast.makeText(this,"aaa",Toast.LENGTH_SHORT,).show();
}

Toast invalidLoginToast = new Toast.makeText(this, "aaa", 3).show();

just remove the part (Toast invalidLoginToast = new) from your coding as you don't need to create object to Toast class to access makeText function, because its static it can be accessed directly using class name itself as Toast.makeText

just write it as

Toast.makeText(this, "aaa", 3).show();

(or)

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

Remove new keyword in front of Toast initialization. use

Toast invalidLoginToast = Toast.makeText(this, "aaa", 3).show();

You don't need to use new keyword while creating Toast as it is provided by factory method inside Toast which does that for you.

Instantiate a Toast object with one of the makeText() methods. This method takes three parameters: the application Context, the text message, and the duration for the toast. It returns a properly initialized Toast object. You can display the toast notification with show()
