[G1 Android Development] T-One:
i have done some research about my problem above, this is what i found:

i've done the following to test that issue:

*Ejected my SDCard

*Cleared the Market App Cache and Data

*Set the app install place to internal and deactivated the "move apps" option

*Cleared dalvik cache in recovery

For testing i tried to install advanced task killer and monitor everything with logcat, this is what i got:

D/vending ( 426): [46] AssetDownloader$DownloadManagerBroadcastReceiver.install

After downloading my phone want to start a service called "cmp=com.android.defcontainer/.DefaultContainerService }" which my phone cant find and cancle the install-process.

I have done the same procedure with external save location, and i got this error:

same error about the DefaultConainterService plus some stuff about my SD-Card.

I'm not a Android developer so i could not what is all about this service, but i hope someone here could!
