facing problem to show the message in toast

Hello i am using this tutorial to set the spinwheel for my webview , its working perfectly after removing this line

Toast.makeText(activity, "Oh no! " + description, Toast.LENGTH_SHORT).show(); and the errot is on actitvity ,

plus i would like to know that if there is no internet connection how we can se开发者_开发技巧t the message in this toast

From the url example you have to write

//Main.java
Toast.makeText(Main.this, "Oh no! " + description, Toast.LENGTH_SHORT).show();
//this is also correct
Toast.makeText(getApplicationContext(), "Oh no! " + description, Toast.LENGTH_SHORT).show();

For internet connectivity checking

That first parameter in makeText() should be a Context. I'm assuming what the author of the tutorial meant by activity was a non-static reference to the Activity class in which you're programming. You would correctly reference it with something like

//MyActivity.java

Toast.makeText(MyActivity.this, "Oh no!" + description, Toast.LENGTH_SHORT).show();

Toast.makeText(MyActivity.this, "Oh no!" + description, Toast.LENGTH_SHORT).show();

otherwise you can also use

Toast.makeText(getApplicationContext(), "Oh no!" + description, Toast.LENGTH_SHORT).show();
