android - App crashes when On onActivityResult with Galaxy S4 -
i have activity takes picture , set imageview image captured, , uploads parse. works fine lg g4, galaxy s4 crashes after press button says want picture, crashes in onactivityresult function. see in log there nullpointerexception, guess because galaxy s4 has less memory lg g4. think understand problem(my assumption memory), have no clue how tackle it.

before doing work decoded bitmap need check decoded well.
// code above if (requestcode == request_code && resultcode == result_ok) { bitmapfactory.options bmpfactoryoptions = new mapfactory.options(); bmpfactoryoptions.injustdecodebounds = true; bmpfactoryoptions.insamplesize = 5; bmpfactoryoptions.injustdecodebounds = false; //imagefilepath image path pass intent bitmap bp = bitmapfactory.decodefile(imagefilepath, bmpfactoryoptions); if (bp != null) { //rotate image 90 degrees matrix rotatematrix = new matrix(); rotatematrix.postrotate(90); bitmap rotatedbitmap = bitmap.createbitmap(bp, 0, 0, bp.getwidth(), bp.getheight(), rotatematrix, false); } // code below
