Out of memory while creating bitmaps on device

use this method to resize your bitmap-

 Bitmap bm=decodeSampledBitmapFromPath(src, reqWidth, reqHeight);

use this Defination-

 public Bitmap decodeSampledBitmapFromPath(String path, int reqWidth,
    int reqHeight) {

final BitmapFactory.Options options = new BitmapFactory.Options();
options.inJustDecodeBounds = true;
BitmapFactory.decodeFile(path, options);

options.inSampleSize = calculateInSampleSize(options, reqWidth,
        reqHeight);

// Decode bitmap with inSampleSize set
options.inJustDecodeBounds = false;
Bitmap bmp = BitmapFactory.decodeFile(path, options);
return bmp;
}
}
  public int calculateInSampleSize(BitmapFactory.Options options,
    int reqWidth, int reqHeight) {

final int height = options.outHeight;
final int width = options.outWidth;
int inSampleSize = 1;

if (height > reqHeight || width > reqWidth) {
    if (width > height) {
        inSampleSize = Math.round((float) height / (float) reqHeight);
    } else {
        inSampleSize = Math.round((float) width / (float) reqWidth);
     }
 }
 return inSampleSize;
}

If you are using resource then replace method with BitmapFactory’s decodeResource method..

 public static Bitmap decodeSampledBitmapFromResource(Resources res, int resId,
    int reqWidth, int reqHeight) {

....
.....
return BitmapFactory.decodeResource(res, resId, options);
}
