The Android Support package is not only for backports. For example, if you want to use ViewPager
, you will need to use the Android Support package. And, in 2014, the Android Support package might get backports of things that are not in whatever your planned android:minSdkVersion
is.
If, instead, you are asking whether it is necessary to use FragmentActivity
, the AppCompat action bar, and similar backports, no, you will not need those.
