Take a look at this post maybe it will help you ....

java.lang.NoClassDefFoundError: java.util.Objects

The exception is thrown because all static methods of java.util.Objects are available above API 19 (Android 4.4.+).

in API 10 (Android 2.3.+) that method doesn't exist in that Android version and NoClassDefFoundError is thrown.

If you want to check api level programmatically you can do:

if (Build.VERSION.SDK_INT >= Build.VERSION_CODES.KITKAT) {
// your code available only above api 19
} else {
// compatibility code
}
