无法解析符号 Val 和 as

Question

When I use this code:

  val km = getSystemService(Context.KEYGUARD_SERVICE) as KeyguardManager;

I get the same error code cannot resolve symbol for val and as.

Answer 1

You are using kotlin based keyword 'val' which is unavailable in the context of java.

use the following to resolve it:

KeyguardManager km = (KeyguardManager) getSystemService(Context.KEYGUARD_SERVICE);

Answer 2
