文章主要目的用作记录生成so库及串口JNI的调用方法 参考博客https://www.jianshu.com/p/a37782b56770 主要有四个步骤: 一、编写需要调用的JNI接口的JAVA类,通过JAVA类生成相对应的.h头文件 二、编写Android.mk和Application.mk,通过实现.h的c++文件与头文件生成对应的so库 最终效果图如下: 1、其中JAVA类Serial...
If you do not care to limit the user's choices, you can either use a form of the showInputDialog method that takes fewer arguments or specify null for the array of objects. In the Java look and feel, substituting null for possibilities results in a dialog that has a text field and lo...
and an architecturally agnostic virtual machine, Java created a new way of programming. Moreover, it has a gentle learning curve and appears to successfully adhere to its own moto - “Write once, run everywhere”, which is almost always true; but Java problems are still present. I’ll be ...
Well, we could of course just wrap the invocation inside a framework object that allows the represented method’s invocation by passing an array with the wrapped method’s parameters: interface SecuredMethod { Object invoke(Object… args); } ...
