android上一个可追踪代码具体到函数某行的日志类

代码如下：
代码如下:
package xiaogang.enif.utils;

public class LogUtils {
private final static int VERBOSE = 0;

log.level = l;
return log;
}
public static LogUtils getLog(Class<?> clazz) {
return new LogUtils(clazz);
}
public LogUtils(Class<?> clazz) {
this.clazz = "[" + clazz.getSimpleName() + "] ";
level = DEFAULT_LEVEL;
}
