Java – Bitmap creation is out of memory

I’m trying to rotate the captured image in onActivityResult() via the camera intent, but I’m occasionally getting an out-of-memory error.

How can I optimize this code?

http://pastebin.com/ieaHS8qB

bmp = BitmapFactory.decodeStream(new FileInputStream(f), null, null);
correctBmp = Bitmap.createBitmap(bmp, 0, 0, bmp.getWidth(), 
                bmp.getHeight(), mat, true);

I tried adding bmp.recycle() and correctBmp.recycle() after these lines, but it didn’t help.

If you develop your application API level 10+ you can add your list

 android:largeHeap="true" //add this entity.

Like

  <application
    android:icon="@drawable/ic_launcher"
    android:label="@string/app_name"
    android:largeHeap="true"
    android:theme="@android:style/Theme.NoTitleBar.Fullscreen" >

Or try this (creating a class).

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

 First decode with inJustDecodeBounds=true to check dimensions
    final BitmapFactory.Options options = new BitmapFactory.Options();
    options.inJustDecodeBounds = true;
    BitmapFactory.decodeResource(res, resId, options);

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

 Decode bitmap with inSampleSize set
    options.inJustDecodeBounds = false;
    return BitmapFactory.decodeResource(res, resId, options);
}

public static int calculateInSampleSize(BitmapFactory.Options options,
        int reqWidth, int reqHeight) {
     Raw height and width of image
    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;
}

Thanks to the code, you can also resize the bitmap.
