Android Context
归因标记
用于特别场景下需要区分context来源时使用
// 创建归因标记，简称Tag
attributionContext = createAttributionContext("initXXXSDK")
解析：
在Context类中的注释的解释如下：返回一个新的不同标记的上线文对象…来区分不同逻辑部分
/**
* Return a new Context object for the current Context but attribute to a different tag.
* In complex apps attribution tagging can be used to distinguish between separate logical
* parts.
*
* @param attributionTag The tag or {@code null} to create a context for the default.
*
* @return A {@link Context} that is tagged for the new attribution
*
* @see #getAttributionTag()
*/
public @NonNull Context createAttributionContext(@Nullable String attributionTag) {
