Toast message from Broadcast Receiver

Question

I have a broadcast receiver and I am trying to show a toast message from it, is this possible ? This code doesn't show the toast but it print the log message in the logcat. Is there some idiotic thing I am doing or what is my problem ?

@Override
public void onReceive(Context context, Intent intent) {
    Log.v("log", "this is shown");
    Toast.makeText(context, "this is not shown"     , Toast.LENGTH_LONG);
}

As lukuluku suggests, creating a `Toast` from a `BroadcastReceiver` isn't necessarily a good thing to do. It's possible your `BroadcastReceiver` may be 'alive' when some other `Activity` is in use. In this case, the `Toast` will make no sense to the user of the device. — Squonk, Oct 26 '11 at 10:22
@Squonk sure, it's not a good thing in general, but useful in [cases like this](http://stackoverflow.com/a/23135951/504611). — Vicky Chijwani, Oct 11 '16 at 20:00

Call the show() method for the Toast.

you forgot to call show() on the Toast.. although i would not recommend creating toasts from BroadcastReceivers.. you might consider using Notifications

I know i'm a little late, but why create toasts from BroadcastReceivers isn't a good idea? – undefined is our god Nov 08 '15 at 01:36

@VictorAlencarSantos Because the user might be confused and won't know which app has created the toast message. Imagine dozens of apps spawning toast messages - this would be more confusion than helpful. – lukuluku Jan 11 '16 at 13:56
Understood! Thanks bro! – undefined is our god Jan 11 '16 at 17:11

Use this

Toast.makeText(context, "this is not shown",Toast.LENGTH_LONG).show();
