私有内部类的构造函数也是私有的吗？

我正在重构一个正在变大的android项目.运行lint为我提供了JSME问题 外部和内部类之间的私有成员访问.考虑以下示例

public class Outer {
    private Inner mInner = new Inner();

    private class Inner {}
}

我得到了这些信息

Name
   private field Inner mInner

Location
   class Outer (default package)

Problem synopsis
   Access to private member of class 'Inner' at line 2

Problem resolution
   Make 'Inner' constructor package-local

public class Outer {
    private Inner mInner = new Inner();

    private class Inner {
        Inner() {}
    }
}

public class Outer {
    private Inner mInner = new Inner();

    private class Inner {
        public Inner() {}
    }
}
