基本用法（类调用）：

//获取系统属性值反射方法public String getSystemProperty(String key) {String v = "";try {Class<?> c = Class.forName("android.os.SystemProperties");Method m = c.getDeclaredMethod("get", String.class);v = (String) m.invoke(c, key);} catch (Exception e) {}if ("".equals(v)) return "no";return v.trim();}

基本用法（实例调用）：

    public List<String> getxxApps() {        List<String> apps = new ArrayList<String>();        try {            Class<?> cl = Class.forName("com.android.xx.cl");            Object con = cl.newInstance();            Method myMethod = VivoCustomManager.getMethod("myMethod",                    null);            apps = (List<String>) myMethod.invoke(con, null);                    } catch (ClassNotFoundException e) {            // TODO Auto-generated catch block            e.printStackTrace();        } catch (InstantiationException e) {            // TODO Auto-generated catch block            e.printStackTrace();        } catch (IllegalAccessException e) {            // TODO Auto-generated catch block            e.printStackTrace();        } catch (NoSuchMethodException e) {            // TODO Auto-generated catch block            e.printStackTrace();        } catch (IllegalArgumentException e) {            // TODO Auto-generated catch block            e.printStackTrace();        } catch (InvocationTargetException e) {            // TODO Auto-generated catch block            e.printStackTrace();        }                return apps;    }
