在Android studio里直接debug调试正常，但发布出来安装就不正常。在安装后连接adb可以看到如下错误日志

报错点为如下

try {
                Constructor<? extends BaseMessageItemHolder> constructor = holderClass.getConstructor(View.class);
                holder = constructor.newInstance(view);
            } catch (NoSuchMethodException e) {
                e.printStackTrace();
                holder = null;
            } catch (IllegalAccessException e) {
                e.printStackTrace();
                holder = null;
            } catch (InstantiationException e) {
                e.printStackTrace();
                holder = null;
            } catch (InvocationTargetException e) {
                e.printStackTrace();
                holder = null;
            }

原因：对应的构造方法没有设置public，导致反射构造器报错。但为啥子Debug时会正常呢？
