Hardwares of my pad are as follows:

processor: Snapdragon ARM CPU

ram: 512MB

flash memory：16gGB flash

opration system：Android 2.2

monitor：10.1 inch,1280x800

When I installed an apk generated by unity, an “INSTALL_FAILED_CONTAINER_ERROR” occurs, why?

Unity 3d do not support my devices? or something else? need help,urgent!

Something more, when I remove the android-8 from the sdk directory(android-2 - android-7 still remain in the directory), an error occurs, "Android
SDK does not include any platforms! Did you run Android SDK setup to install the platform(s)? minimum platform required for build is Android2.2(API level 8).
Isn’t it says that the support os is android 2.x?

Additionally, my packed apk can run on a simulator correctly.

Did you use Build&Run or some other mechanism to install the .apk? Can you have a look at the logcat to see if it includes any additional info?
(the logcat can be accessed through the command line tool ‘adb’ found under android_sdk_dir/tools. some more info available here)

OS 2.2 (platform API level 8) is needed to build the .apk (otherwise we would not be able to benefit from 2.2 features like installing to SD card). That does not mean the .apk won’t run on a 2.1 device; the 2.2 features will just be ignored on those devices.
