I am trying rotate taken image in onActivityResult()
from camera Intent, but I am getting Out of memory errors occasionally.
How can I optimize this code?
bmp = BitmapFactory.decodeStream(new FileInputStream(f), null, null);
correctBmp = Bitmap.createBitmap(bmp, 0, 0, bmp.getWidth(),
bmp.getHeight(), mat, true);
I was trying to add bmp.recycle()
and correctBmp.recycle()
after these lines, but it didn't help.

if you develope your application api level 10+ you can add your manifest this
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 (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 that code you can also resize your bitmap.

try to add below code before decodestream and pass option 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);
