SYSTEM_UI_FLAG_LOW_PROFILE cannot be resolved or is not a field for google threadsample

Question

I have import the threadsample code from https://developer.android.com/training/multiple-threads/index.html, but I got errors after I import it.

They are : SYSTEM_UI_FLAG_LOW_PROFILE cannot be resolved or is not a field SYSTEM_UI_FLAG_HIDE_NAVIGATION cannot be resolved or is not a field

The project minSdkVersion=11 and targetSdkVersion=17, and I have already setup the support.v4 with it.

Does anyone have the same problem? How to fix it?

Thanks in advance.

That is a mistake SYSTEM_UI_FLAG_LOW_PROFILE is included in API >= 14 and SYSTEM_UI_FLAG_LAYOUT_HIDE_NAVIGATION is included in API >= 16
So you need minSdk=14. See the document at http://developer.android.com/reference/android/view/View.html#SYSTEM_UI_FLAG_LOW_PROFILE. Need to change the project build target to Android 4.0 to get rid of the errors.
