you can install another launcher such as launcher pro, adw launcher, etc and the problem will be solved
I am using Launcher Pro, and I have this same problem, so that does not resolve it for me. After every reboot (and sometimes without a reboot), all of my SDCard-installed apps disappear, their icons turn to generic android icons, and I get the message that the apps aren't installed when I try to run them. I switch to the built-in Launcher (twLauncher) and have the same problem. takes multiple reboots, removing the SD card, replacing it, rebooting, i don't know what all, and eventually, the problem will go away, but I will be left with not knowing what exactly I did to resolve it. Meanwhile I am without my apps for sometimes hours, or the rest of the day. (Sometimes my apps are all there when I go to bed, but are all gone when I wake up. Not sure if a reboot happened during the night, or what.)
This has only been happening the last month or so, and i have had this phone for a year (on Froyo for more than six months). Not sure if there was some update, or something I did to cause this, but it is very frustrating.
I reset back to factory, and reinstalled apps, then moved them to SD Card, and had the same problem.
Also, I rooted my phone about the same time this started, so I assumed that was the culprit, but I have unrooted, wiped out the phone, and started over, and still the problem persists.
Anybody have any idea what is causing this?
Thanks for any help,
Griffin
P.S. I have a Samsung Epic 4g, which only has about 400Mb of internal storage available for apps, so no way to fit all of them on there.
