Twitter widget appears to be broken: "Application not installed" I'm having trouble with the Twitter app on my Samsung Galaxy S4. The widget was misbehaving, so I thought I would remove it from my homescreen and put it back. What has happened instead is that the widget refuses to come back. Whenever I try to place it, it will simply say "Application not installed."

I've tried the following:


Reboot my phone
Reinstall the Twitter app
Clear the app's cache and data
Remove the MicroSD card, reinstall, and attempt to use the widget
Several combinations of the above.


Can someone help me figure out what is going wrong here? I realize this is probably a silly question
I had a similar problem with another app (not Twitter) I went into my app manager and saw that the app was installed on my "External Storage" even if I never moved it there. I moved it back to the Internal Storage and it was fixed. My card was already fine to begin with but for some reason, the widget didn't like it. 
Anyway, I never recommend putting apps on the SD card, it slowed my S3 to a crawl. Keep it for media and docs.
