Hi Ziva,

I re-did the challenge, and i used the below commands, have a look:

Toast allDoneToast = Toast.makeText(this,"All done!",Toast.LENGTH_LONG); allDoneToast.show(); Toast.makeText(this,"Yay!",Toast.LENGTH_LONG).show();

String message = "Your message"; Toast.makeText(MainActivity.this, message,message.LENGTH_LONG).show();

For more info or applying more features, have a look at this website: http://developer.android.com/guide/topics/ui/notifiers/toasts.html

My mistake: it should not be message.LENGTH_LONG but Toast.LENGTH_LONG;

Hi Ali,

Tnx for helping me. That's what I thought, but I keep getting a compiler error.

I've added your code to an existing code: String message = "All done!"; Toast allDoneToast = Toast.makeText(this,message,Toast.LENGTH_LONG); allDoneToast.show(); Toast.makeText(this,"All done!", Toast.LENGTH_LONG).show();; String message = "Your message"; Toast.makeText(MainActivity.this, message,Toast.LENGTH_LONG).show();

And the error report says (I've been getting the "variable message is already defined in method run" all the time): JavaTester.java:79: error: variable message is already defined in method run() String message = "Your message"; Toast.makeText(MainActivity.this, message,Toast.LENGTH_LONG).show(); ^ JavaTester.java:79: error: cannot find symbol String message = "Your message"; Toast.makeText(MainActivity.this, message,Toast.LENGTH_LONG).show(); ^ symbol: class MainActivity location: class JavaTester 2 errors

'''Toast allDoneToast = Toast.makeText(this,"All done!",Toast.LENGTH_LONG); allDoneToast.show(); Toast.makeText(this,"Yay!",Toast.LENGTH_LONG).show();'''

Toast allDoneToast = Toast.makeText(this,"All done!",Toast.LENGTH_LONG);
allDoneToast.show();
Toast.makeText(this,"Yay!",Toast.LENGTH_LONG).show();
