How to solve a high resolution image out of memory?

Question

Below is the code I use to read my image file when I save my image file using FileProvider:

public static Bitmap readBitmapFromIntentReturn(Context context, Intent intentReturn, Uri uri) {
                try {
                    AssetFileDescriptor fileDescriptor = null;
                    fileDescriptor = context.getContentResolver().openAssetFileDescriptor(uri, "r");

                    BitmapFactory.Options options = new BitmapFactory.Options();
                    options.inJustDecodeBounds = true;
                    BitmapFactory.decodeFileDescriptor(fileDescriptor.getFileDescriptor(), null, options);

                    options.inSampleSize = SystemFunctions.calculateInSampleSize(options);

                    options.inJustDecodeBounds = false;
                    Bitmap bitmap = BitmapFactory.decodeFileDescriptor(fileDescriptor.getFileDescriptor(), null, options);
                    return bitmap;
                } catch (IOException e) {
                    e.printStackTrace();
                }
            return null;
        }

2. Method use to resize the image before I upload it or other, not sure the size is resize correctly or not:

    public static int calculateInSampleSize(BitmapFactory.Options options) {
                final int reqHeight = 360;
                final int reqWidth = 360;

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

                if (height > reqHeight || width > reqWidth) {

                    final int halfHeight = height / 2;
                    final int halfWidth = width / 2;

                    while ((halfHeight / inSampleSize) > reqHeight
                            && (halfWidth / inSampleSize) > reqWidth) {
                        inSampleSize *= 2;
                    }
                }

                Log.d("TestSampleSize", "TestSampleSize : " + String.valueOf(inSampleSize));
                return inSampleSize;
            }

when you say "a memory leak happens" do you mean that you get an OutOfMemoryException? — lelloman, Jul 31 '17 at 09:18
OutOfMemoryException does not mean memory leak. in some cases, a memory leak might lead to an OutOfMemoryException but in your case the cause it's probably your image being too big — lelloman, Jul 31 '17 at 09:33
@lelloman but y it working for asus Android 5 phone but not working for android 6 Samsung galaxy S6. I have done the samplesize to reduce the size alrdy. — Dylan Ang, Jul 31 '17 at 09:40
you probably haven't reduced it enough, without seeing the code it's a wild guess — lelloman, Jul 31 '17 at 09:46
@lelloman I will upload the code for the reduce part. can u check for me? — Dylan Ang, Jul 31 '17 at 09:47
