java - Saving Android FaceDetector.Face[] on rotation -

-

i trying save facedetector.face array on screen rotation, facial detection not have performed again. app seems take longer normal rotation. however, can't store faces array in onsavedinstancestate since isn't serializable. tried extending facedetector.face implementing serializable, doesn't have default constructor. should save object array 1 on rotation, didn't implement?

i suggest creating static fragment without ui on activity. once that, can use store data. keep in mind facedetector.face, object holds locations on bitmap , not bitmap itself.

i'm attempting write python 2/3 compatible routine fetch csv file, decode latin_1 unicode , feed csv.dictreader in robust, scalable manner. for python 2/3 support, i'm using python-future including imporing open builtins , , importing unicode_literals consistent behaviour i'm hoping handle exceptionally large files spilling disk, using tempfile.spooledtemporaryfile i'm using io.textiowrapper handle decoding latin_1 encoding before feeding dictreader this works fine under python 3. the problem textiowrapper expects wrap stream conforms bufferediobase . unfortunately under python 2, although have imported python 3-style open , vanilla python 2 tempfile.spooledtemporaryfile still of course returns python 2 cstringio.stringo , instead of python 3 io.bytesio required textiowrapper . i can think of these possible approaches: wrap python 2 cstringio.stringo python 3-style io.bytesio . i'm not sure how approach - need write such wrapper or 1 ex
