Answer 1

This is because of low memory, size of your image file is large, to solve this problem add this method in your class:

public static Bitmap decodeImageFile(File f,int WIDTH,int HIGHT){
             try {
                 //Decode image size
                 BitmapFactory.Options o = new BitmapFactory.Options();
                 o.inJustDecodeBounds = true;
                 BitmapFactory.decodeStream(new FileInputStream(f),null,o);

                 //The new size we want to scale to
                 final int REQUIRED_WIDTH=WIDTH;
                 final int REQUIRED_HIGHT=HIGHT;
                 //Find the correct scale value. It should be the power of 2.
                 int scale=1;
                 while(o.outWidth/scale/2>=REQUIRED_WIDTH && o.outHeight/scale/2>=REQUIRED_HIGHT)
                     scale*=2;

                 //Decode with inSampleSize
                 BitmapFactory.Options o2 = new BitmapFactory.Options();
                 o2.inSampleSize=scale;
                 return BitmapFactory.decodeStream(new FileInputStream(f), null, o2);
             } catch (FileNotFoundException e) {}
             return null;
            }

Then call this method where you using this:

Bitmap b = decodeFile(f);

use this insted:

Bitmap b = decodeImageFile(f, 1280, 720);
