Because in android 4.4 and above, the implements of *decodeFile* method in BitmapFactory changes, the original use of BufferedInputStream is removed.(see this diff: https://android.googlesource.com/platform/frameworks/base/+/ca32021b43f326af7d3f4ae041f8db297f98a518%5E%21/#F9 <https://android.googlesource.com/platform/frameworks/base/+/ca32021b43f326af7d3f4ae041f8db297f98a518%5E%21/#F9> )

(more than 10%~50%) the comment of changes of the method say : "*Remove the call to mark, which is now done natively.*" is it a bug introduced by optimization？ -- You received this message because you are subscribed to the Google Groups "Android Developers" group.
