Getting images from a string path to be viewed in an imageview

Question

I have some picture paths stored in a datastore and i am trying to convert them into drawables and display the in my image view, for some reason im getting a null pointer exception. Can someone please help me? Thanks

String pathName = selectedPlayer.getPicture(); Toast.makeText(this, pathName, Toast.LENGTH_SHORT).show(); Drawable d = Drawable.createFromPath(pathName); imageView.setImageDrawable(d);

what are the values in pathName ? Is it local image path(SDCARD) or web url ? — Chirag

logcat usually also prints line number at which the exception occured — Alexander

localimage.. Images are stored on the emulators gallery and the paths are stored in a datastore. — Lilu Patel

You must check file name is not null

then check that first if file exists or not

if(pathName!=null && pathName!="") <--CHECK FILENAME IS NOT NULL { File f = new File(pathName); if(f.exists()) <-- CHECK FILE EXISTS OR NOT { Drawable d = Drawable.createFromPath(pathName); imageView.setImageDrawable(d); } }

EDIT : You have to initialize your imageview first like

imageView=(ImageView)findViewById(R.id.yourimageviewid);

hmm now the null pointer exception is here: imageView.setImageDrawable(d);
@NiraliPatel Have you initialized imageView using findViewById() ?

Look at imageView it should not be null.

And after that try this :

bm = null; try { bm = BitmapFactory.decodeFile(imageView); } catch (OutOfMemoryError e) { e.printStackTrace(); } imageView.setImageBitmap(bm);
