Go to this page: http://developer.android.com/reference/android/widget/Toast.html Under the description of the method makeText, you will find: Parameters context The context to use. Usually your Application or Activity object. Now, in Service, you have getApplication(), which you can cast to Context and use, if you do not want to use getAppllicationContext() Why dont you give a try to both of them? It will not harm your PC or device. What if it works?
