Unwanted Toast Notifications Android 4.0 3. HTC Sense 3.6. I have some app installed on my SD card (1 of 195), that pops up a toast notification on boot/SD mount that says "Have a good day!" And lasts for nearly a minute. Does anyone know an easy way for me to figure out what app is causing that? Since toasts aren't a permission, an app like addon detector won't work. Cheers!
Sounds like there's an app that is listening for the permission android.permission.RECEIVE_BOOT_COMPLETED and firing the toast much to your annoyance. 

You need to check with yourself by asking yourself those two vital questions - 


When did this happen? 
What was the last app you installed?


And backtrace it to the offending app. For an example, check out this and narrow it down to that aforementioned permission and see which one is it and un-install it.
