import android.content.pm.packageParser cannot be resolved

I am using the available code of PackageInstaller for testing my own application of installing and uninstalling the apk over the device.The开发者_JAVA技巧re is lots of error within Froyo for building this app. Please help me out of this.

See PackageInstaller code here.

There is a short tuto here.
