问题
I am trying to get a Toast notification to show up on my Nexus 7 tablet - however, they will not show. I use custom Toast messages throughout most of my app, but even something as simple as:
Toast.makeText(MyActivity.this, "generic toast message", Toast.LENGTH_LONG).show();
is not working.
I have tested this app on other devices, including a Nexus 1 phone (2.3), MyTouch (2.2), and Acer Iconia tablet (4.0). The toast messages appear on all other devices except this Nexus 7 tablet (4.1).
Is there a user setting that allows the disabling of Toast notifications in an application? Or are Toast messages handled differently post-4.1? These are my only ideas currently. I've searched this problem on Google and haven't gotten a single link regarding a similar issue.

Maybe this post can help you.
Sounds like a bug.
Edit: In case the link dies, essentially:
Go to Settings -> Apps -> My_App and locate a little box labeled "Show Notifications" underneath it. If it is unchecked, check it.
