can I use this with minSdkVersion 15?

[N3ur0t]

if(Build.VERSION.SDK_INT < 16) {
    requestWindowFeature(Window.FEATURE_NO_TITLE);
    this.getWindow().setFlags(WindowManager.LayoutParams.FLAG_FULLSCREEN, WindowManager.LayoutParams.FLAG_FULLSCREEN);
}else{
    int full = View.SYSTEM_UI_FLAG_FULLSCREEN;
    if(Build.VERSION.SDK_INT >= 19) {
        full = View.SYSTEM_UI_FLAG_LAYOUT_STABLE
    | View.SYSTEM_UI_FLAG_LAYOUT_HIDE_NAVIGATION
    | View.SYSTEM_UI_FLAG_LAYOUT_FULLSCREEN
    | View.SYSTEM_UI_FLAG_HIDE_NAVIGATION
    | View.SYSTEM_UI_FLAG_FULLSCREEN
    | View.SYSTEM_UI_FLAG_IMMERSIVE_STICKY;
    }
    decorView.setSystemUiVisibility(full);
        ActionBar navButtons = getActionBar();
        navButtons.hide();
    }

setContentView(R.layout.cover);

I forgot to say that
SYSTEM_UI_FLAG_IMMERSIVE_STICKY needs api 19
and the other needs api 16
but I don't know if ask for compile time or what

Have you had a look at the Android Javadocs for View?

https://developer.android.com/reference/android/view/View.html

Just set the API level in the panel on the left, and it will grey out anything that isn't available.

You can also check that everything works by creating an AVD at the specific API level you want to test.

you should use @SuppressLint("NewApi") on the method that holds the respective code, otherway the Lint will complain and no compilation is possible.

E.g. in my code I have something like:
@SuppressLint("NewApi")
public static String getRealPathFromURI(Context context, Uri uri) {

boolean isNewerThanKitKat = VERSION.SDK_INT >= VERSION_CODES.KITKAT;

// DocumentProvider
if (isNewerThanKitKat && DocumentsContract.isDocumentUri(context, uri)) {
....
