Sam first tries to use:
Pm setInstallLocation 2
It is useless to install it later.

Later, I tried the following:
* Choose "other settings"> "Storage Device"> "specify the default storage device" and select the USB flash disk as the default storage device.
# Pm install-s xxxx.apk *

Then you can succeed.
