Really appreciate you help.

Answer 1

this is normal according to google Android engineers.

Refer to https://code.google.com/p/android/issues/detail?id=198567

This happens when you compile against a higher api level than the deployed device api level. The logs are indicating that, some of the methods are not available and the virtual machine is going to replace them with the alternative implementation.

It just means that you have a reference to a method which is not available on that platform where you code currently runs on.

To solve your problem write a runtime switch:

if(Build.VERSION.SDK_INT >= Build.VERSION_CODES.LOLLIPOP) {
    // You can use here an API which was added in Lollipop.
}
