How to pass image id to alarm service?

I use alarm service to start notifications. I want to have different image in notification based on which pendingIntent has called it. I tried passing this id via intent, but the app crashes

        Intent myIntent = new Intent(AndroidAlarmService.this, MyAlarmService.class);
        //pass something to intent
        myIntent.putExtra("param", 999);

        pendingIntent = PendingIntent.getService(AndroidAlarmService.this, 0, myIntent, 0);

And in service class, I catch it via

int test =  intent.getExtras().getInt("param", -1);
Toast.makeText(this, test, Toast.LENGTH_SHORT).show();//the app crashes here!

However, the app crashes in the marked line.

How should I pass image id to the service so that I can use this ID to set image in the norifications?

EDIT

Here is the logcat when error happens

Toast.makeText(this, test, Toast.LENGTH_SHORT).show();//the app crashes here!

Means you are sending an int as the message. This in turn means that you're telling Android to look for a String with resource id 999. Change it to:

Toast.makeText(this, String.valueOf(test), Toast.LENGTH_SHORT).show();//the app won't crash here
