推荐答案

遗憾的是没有可靠的解决方案，因为没有针对此类功能的官方 Android API.有一个 hacky解决方案"适用于一些有根设备.但正如我所说，没有什么可靠的.请参阅此帖子.

Unfortunately there is no reliable solution for this as there is no official Android API for this kind of functionality. There is a hacky "solution" that works on some rooted devices. But as I said, nothing reliable. See this post.
