Android gets and compresses bitmap images through URI

Many people will use media.getbitmap in onactivityresult to get the returned pictures when calling the gallery to select pictures, as follows:

However, the media.getbitmap () method is not a good way to obtain known URI images. Let's take a look at the source code of the media.getbitmap () method:

Improve the code in onactivityresult:
