Installing on Device error using ‘adt -installApp’
Today I was updating the Ant files for compiling for AIR for Android and iOS in Eclipse to make sure they can use the latest AIR SDK, 3.1.
As I was doing this I ran into the following error while using the -installApp from adt: INSTALL_FAILED_CONTAINER_ERROR
The fix is to mount your device and remove the /.android_secure/smdl2tmp1.asec file.
Unmount and remount your device, run the ‘installApp’ command again.
Now you can install again directly to your device
