Why an incorrectly selected color space of a picture can lead to an android crash?

Answer 1

because a picture is a data format that is often compressed (gif, jpg, png), and there is an algorithm for decompressing it.
The library that was used in android had a bug, which consisted in the fact that when trying to decode an image in a color space (format) that was incomprehensible to it, it did not give an error that the format was unknown, but tried to do this and crashed with an exception, leading to a crash of the application responsible for the user interface. And since this is an important application, without which the user cannot use the phone, the error turned out to be too critical and difficult to fix.
