Bitmap creates from memory

I try to rotate the captured image in onActivityResult() from the Intent camera, but sometimes I get errors from memory.

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 to add bmp.recycle() and correctBmp.recycle() after these lines, but this did not help.

if you develop the api level of your application 10+, you can add your manifest to this

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

as

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

or try this (Create 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 this code, you can also resize the bitmap.

try adding the code below before the decoder and the skip parameter as a parameter.

 BitmapFactory.Options options = new BitmapFactory.Options(); options.inSampleSize = 5; options.inPurgeable = true; options.inInputShareable = true; bmp = BitmapFactory.decodeStream(new FileInputStream(f),null, options);
