I tried some of screen orientation checks for android and looped that 100,000 times.. The other does same but 240 times slower!

bool-land.xml

<?xml version="1.0" encoding="utf-8"?>
<resources>
    <bool name="is_landscape">true</bool>
</resources>

bool-port.xml

<?xml version="1.0" encoding="utf-8"?>
<resources>
    <bool name="is_landscape">false</bool>
</resources>

landtest.java

long startTime = System.currentTimeMillis();
long sum = 0;
for(int i = 1; i <= 1000000 ; i ++) {
    // D/LANDTEST: sum: 500000500000 / time: 32
    if (getResources().getConfiguration().orientation == Configuration.ORIENTATION_LANDSCAPE) {
        sum += i;
    }
    // D/LANDTEST: sum: 500000500000 / time: 7743
    if (getResources().getBoolean(R.bool.is_landscape)) {
        sum += i;
    }
}

Log.d("LANDTEST", "sum: " + sum + " / time: " + (System.currentTimeMillis() - startTime));
