推荐答案

有没有API的但在Android的直接做到这一点。但是，你可以把应用程序的屏幕截图，然后将它们合并做一个视频输出图像。

There are no APIs yet in Android to do this directly. However, you could take screenshots of the app, and then merge them to make a video out of the images.

然而，这个过程是相当繁琐，而且很可能会采取了大量的研究和调查。

However, this process is quite tedious, and would probably take a lot of research and investigation.

既然你知道如何采取截图，一个良好的起点将是寻找库/ API，这些API可以在一系列的图像，并将它们转换成视频。

Since you know how to take screenshots, a good starting point would be to look for libraries/APIs that can take in a series of images, and convert them into a video.

的ffmpeg / JMF 可能是两个很好的出发点。

ffmpeg/JMF could be two good starting points.
