DUNIA ANDROID

according to F-Secure, trojans have been found in some apps (apk files), including those available in the Android Market. these trojans usually come with apps claiming new Angry Bird Seasons, Talking Tom Cat downloads, etc. once you installed them on your devices, they will send SMS messages to Russia, Germany and some other countries which cost 2 to 6 Euros each.

sources also claimed that the trojans developers have registered several accounts with the Android Market, and Google has no solutions yet to prevent them from flooding the market

when you download and install apps from the market, sometimes you will find that INSTALL_FAILED_CONTAINER_ERROR in the log or "Application not installed" error

they are usually SDCARD related problem, do this and reinstall your app and see if it helps:

- unmount external sdcard
goto settings-> sd card and phone storage -> unmount sd card

if you can install the app after, then it's should be sdcard related problem. to avoid or fix this permanently, do this (root is needed):

- change the permission of /mnt/secure/asec/smdl2tmp1.asec to 777
OR
- delete /mnt/secure/asec/smdl2tmp1.asec

if you wanna save some disk space under /system, here is the list for reference and tested (by assuming deodexed stock apps used)
