java - NullPointerException at createBitmap(). Using an Adapter to inflate a Bitmap into a ListView's rows -

-

i'm getting nullpointerexception @ createbitmap. on research, i've come across people suggesting it's because of low memory. i'd find out if there's in code changed make work. reference, i'll post xml file of row give idea of how should fit in.

here's function gives error (i'm trying make image circular, function):

public bitmap getcroppedbitmap(bitmap bitmap, view view) {     bitmap output;     try {         view.builddrawingcache(true);         output = bitmap.createbitmap(bitmap.getwidth(), bitmap.getheight(), //error here                 bitmap.config.argb_8888);     }finally {         view.setdrawingcacheenabled(false);     }      final rect rect = new rect(0, 0, bitmap.getwidth(), bitmap.getheight());      canvas canvas = new canvas(output);      final paint paint = new paint();     paint.setantialias(true);      int halfwidth = bitmap.getwidth()/2;     int halfheight = bitmap.getheight()/2;      canvas.drawcircle(halfwidth, halfheight, math.max(halfwidth, halfheight), paint);      paint.setxfermode(new porterduffxfermode(porterduff.mode.src_in));      canvas.drawbitmap(bitmap, rect, rect, paint);      return output; }

here's xml code row:
