android - E/dalvikvm: Could not find class java.nio.file.Path,

Question

安卓项目中要用到jackson库，但是运行时报错
E/dalvikvm: Could not find class 'java.beans.Transient', referenced from method com.fasterxml.jackson.databind.ext.Java7SupportImpl.<init>
E/dalvikvm: Could not find class 'java.nio.file.Path', referenced from method com.fasterxml.jackson.databind.ext.Java7SupportImpl.getClassJavaNioFilePath
W/Java7Support: Unable to load JDK7 types (annotations, java.nio.file.Path): no Java7 support added

stackoverflow上有一个帖子，但是并不明白该怎么处理

He means:

If these Warning信息打扰到你，你可以将log级别调为ERROR do not affect the use of functions, it is just that Android lacks these APIs.

In proguard 中忽略这些WarningLog:

-dontwarn java.nio.file.**
