  还有个问题就是，字体也可以用px吗 ？

//第一步：查看源码有两个地方有这个文字提示
Preconditions.checkNotNull(mApplication, "Please call the AutoSizeConfig#init() first");
Preconditions.checkNotNull(mActivityLifecycleCallbacks, "Please call the AutoSizeConfig#init() first");

//第二步：再进去看代码如下所示
//可知传进来的reference为null空值导致出现问题
    public static <T> T checkNotNull(T reference, Object errorMessage) {
        if (reference == null) {
            throw new NullPointerException(String.valueOf(errorMessage));
        } else {
            return reference;
        }
    }

//第三步：查看什么时候创建mApplication和mActivityLifecycleCallbacks对象
//mActivityLifecycleCallbacks对象是在AutoSizeConfig类中的init方法中创建的，第206行
//mApplication对象实在AutoSizeConfig类中init方法中赋值的，第171行
//而init初始化的操作又是在InitProvider类中的onCreate方法中初始化的，(Application) getContext().getApplicationContext()获取全局application会不会出现问题呢？而这个需要的application上下文能否让开发者传递进来呢？
