Android get Exif information issue -


in order exif information of image,i wrote codes below:

exifinterface exif = new exifinterface(path); string aaa= (exif.getattribute(exifinterface.tag_datetime));

i add read,write permission in androidmanifest.xml

<uses-permission android:name="android.permission.write_external_storage" /> <uses-permission android:name="android.permission.read_external_storage" />

now problem specific folder, such /storage/emultaed/0/pictures,/storage/emultaed/0/download, return values of exif.getattribute(...) null.

i wondering if there 3rd party lib can solve issue? help.

some pictures work fine - problem data, not code. suspect devices/applications encode exif data in non-standard way exifinterface cannot parse. can use exiftool dump exif, , modify , standardise it

consider code: test = function() { } t = new test(); (var = 0; < 8; i++) { result = t instanceof test; } if change number of iterations 8 9 , loop take 100 times longer complete in latest version of firefox (41.0.1). tested on 2 different pcs , magic limit 8. here jsperf test used: http://jsperf.com/instanceof-8-times-vs-9-times does have idea why might happen? seems specific instanceof . not happen if else object, example check property. note: filed bugzilla bug this. jan de mooij mozilla team has posted details in bugzilla thread . here's simplistic interpretation of highly technical answers: in i < 8 case, firefox smart enough hoist result = t instanceof test; statement out of loop (according tests, doesn't seem omit altogether). in i < 9 case, apparently doesn't optimization . why? reason not clear, related fact 9 iterations threshold above function considered "hot" enough run through jit compiler. i < 8 cas...
