android - OutOfMemory Error when trying to rescale a Bitmap -

im trying scale bitmap make fit because device wont show images > 2048.

i found solution app crashes when choose/take pic.

that piece of code: (inside onactivityresult)

currimageuri = data.getdata();                 path=(getrealpathfromuri(currimageuri));                  drawable d = drawable.createfrompath(path);                 image.setvisibility(view.visible);                 mphoto=drawabletobitmap(d);                 bitmap sized = mphoto;                 if(mphoto.getheight()>=2048||mphoto.getwidth()>=2048){                 sized = bitmap.createscaledbitmap(mphoto, (int)(mphoto.getwidth()*0.8), (int)(mphoto.getheight()*0.8), false);                 }                  image.setimagebitmap(sized); 

logcat:

line 149 is:

sized = bitmap.createscaledbitmap(mphoto, (int)(mphoto.getwidth()*0.8), (int)(mphoto.getheight()*0.8), false); 

could tell me can prevent crashing? thanks!

update:

app still crashes:

code:

currimageuri = data.getdata();                 path=(getrealpathfromuri(currimageuri));                  drawable d = drawable.createfrompath(path);                 image.setvisibility(view.visible);                 mphoto=drawabletobitmap(d);                 bitmap sized = mphoto;                 if(mphoto.getheight()>=2048||mphoto.getwidth()>=2048){                     sized=getresizedbitmap(mphoto,(int)(mphoto.getheight()*0.8),(int)(mphoto.getwidth()*0.8));                 }                  image.setimagebitmap(sized);          

please have @ related question:

high resolution image - outofmemoryerror

i recommend put image drawables folder. there, load appropriate size using code below. reduce memory usage of app , use memory needed.

make sure have 1 instance of bitmap in memory. after displaying it, call recycle() , set reference null.

this how load images:

public  bitmap scaledownbitmap(bitmap photo, int newheight) {       final float densitymultiplier = getresources().getdisplaymetrics().density;       int h= (int) (newheight*densitymultiplier);      int w= (int) (h * photo.getwidth()/((double) photo.getheight()));       photo = bitmap.createscaledbitmap(photo, w, h, true);       return photo; } 

use this:

imageview.setimagebitmap(scaledownbitmap(youroldbitmap, 300)); 

be aware not use high value newheight , keep in mind densitymultiplier.
