Android Gradient on Lollipop not working. - API 21

Question

When I try to use Gradient on Lollipop, it doesnt work. While it works on all previous versions.

Here is my example:

Answer 1

int sdk = android.os.Build.VERSION.SDK_INT;
    if (sdk < Build.VERSION_CODES.LOLLIPOP) {
        //in your gradient use android:gradientRadius="500"
    } else {
      // in your gradient use android:gradientRadius="80%p" or 
      // android:gradientRadius="200dp"

Try write two different xml files using different gradientRadius style
