I given my application target as 21. So I can use the Material Design API's. But when I run the same on older devices whether I have to define different layout or theme or how it could me.
And also I have read the official document Maintaining Compatibility. But still I was not clear to use the material theme on android devices less than 5 os.
And also where can I find the Android 5 related XML tags. And how the same tags applied when running on devices less than 5.
Please help me on this. Thanks in advance.
