Android used to run on Dalvik VM.
Android 曾经运行在Dalvik VM.
Dalvikhad a bug allowing classes to override parent's package-private methods.
Dalvik有一个错误，允许类覆盖父的包私有方法。
So when they switched to ART, they fixed this, so it no longer overrides the parent's method,
Now when such a scenario is detected, it logs a warning, making sure you're aware of the behavior change.
所以当他们切换到 时ART，他们修复了这个问题，所以它不再覆盖父级的方法，现在当检测到这种情况时，它会记录一个警告，确保你知道行为的变化。
It seems that some support-libclasses (PorterDuffColorFilter, VectorDrawableCompat) have such scenario, so ARTnotifies you.
好像有些support-lib类 ( PorterDuffColorFilter, VectorDrawableCompat) 有这样的情况，所以ART通知你。
I think it's safe to ignore this, unless this is your own code, in which case I would either change the method's name, or test on Android running Dalvik(pre-4.1) and running ART(4.1+)
我认为忽略这一点是安全的，除非这是您自己的代码，在这种情况下，我要么更改方法的名称，要么在运行Dalvik（4.1 之前）和运行ART（4.1+）的Android 上进行测试
