Get a Video thumbnail from Content Uri on Android

I have been using CameraX on Android for a while now and one of the issues I faced was that after recording a video and getting the video Uri, I needed a thumbnail to display the most recent video in my ImageView. After much research, the solution I fell on was relatively easy. The solution requires just two lines of code.

We will use Android’s MediaMetadataRetriever framework.The method to use is MediaMetadataRetriever.getFrameAtTime(). This method should be called only after calling MediaMetaDataRetriever.setDataSource(Content,Uri). The full source code is shown below.

If the method succeeds, it returns a bitmap and you can set it to an ImageView. This was really a short read right.

Cheers!
