SnapCache 类中，存在直接的字符串拼接，由于外部是多个 view node，相处于循环中，会导致大量的 StringBuilder 构建，导致严重的内存抖动

举例如下

private final LruCache<String, String> mLruCanonicalName = new LruCache<>(64); 

public String getCanonicalName(Class<?> cls) {
        if (cls == null) {
            return null;
        }
        String canonicalName = mLruCanonicalName.get(cls.hashCode() + "");// 此处无需转成字符串，直接用 int 即可
        if (canonicalName == null) {
            canonicalName = cls.getCanonicalName();
            if (TextUtils.isEmpty(canonicalName)) {
                canonicalName = "Anonymous";
            }
            mLruCanonicalName.put(cls.hashCode() + "", canonicalName);
        }

        return canonicalName;
    }

建议将 private final LruCache<String, String> mLruCanonicalName = new LruCache<>(64); 改为private final LruCache<Integer, String> mLruCanonicalName = new LruCache<>(64);，同时相关方法，去掉 + ""
