Description Jim Bennett 2017-10-15 22:06:09 UTC
The underlying Java implementation for Android.OSBuild.Serial has changed from a field called SERIAL to a getSerial method. Unfortunately both implementations map to a C# property called Serial meaning the old API has been replaced. If you call Serial on an app build using API 26 on a device running API25 or less you get a missing method exception.

There is no workaround as the pre-26 SERIAL field is no longer available, you have to access it via reflection:

if (Build.VERSION.SdkInt >= BuildVersionCodes.O)
    serial = Build.Serial;
else
{
    var field = Java.Lang.Class.FromType(typeof(Build)).GetField("SERIAL");
    serial = field.Get(null).ToString();
}

This is fixed in upcoming 15.4 and 15.5 builds. I'm marking this as a duplicate. Thanks for the report!
