Qt 调用 Java 方法笔记 假设遇到相似的错误: error: undefined reference to '_jstring* QAndroidJniObject::callStaticMethod<_jstring*>(char const*, char const*)' 那就是你使用了一个错误的函数来调用 Java 方法了. The main difference is that QAndroidJniObject::callMethod returns a primitive d
举一个native方法调用解释执行的Java方法的实例,如下: public class TestJNI { static { System.load("/media/mazhi/sourcecode/workspace/projectjava/projectjava01/src/main/java/libdiaoyong.so"); } public static int getResult() { return 2; } public static native int get()
需求如下:(1)定义一个Circle类,包含一个double型的radius属性代表圆的半径,一个findArea()方法返回圆的面积. (2)定义一个类PassObject,在类中定义一个方法printAreas(),该方法的定义如下: public void printAreas(Cirlce c, int times) 在printAreas方法中打印输出1到time之间的每个整数半径值,以及对应的面积.例如,times为5,则输出半径1,2,3,4,5,以及对应的圆面积. 在main方法
