BitmapFactory.decodeFile out of memory with images 2400x2400
- by alasarr
I need to send an image from a file to a server. The server request the image in a resolution of 2400x2400.
What I'm trying to do is:
1) Get a Bitmap using BitmapFactory.decodeFile using the correct inSampleSize.
2) Compress the image in JPEG with a quality of 40%
3) Encode the image in base64
4) Sent to the server
I cannot achieve the first step, it throws an out of memory exception. I'm sure the inSampleSize is correct but I suppose even with inSampleSize the Bitmap is huge (around 30 MB in DDMS).
Any ideas how can do it? Can I do these steps without created a bitmap object? I mean doing it on filesystem instead of RAM memory.
This is the current code:
// The following function calculate the correct inSampleSize
Bitmap image = Util.decodeSampledBitmapFromFile(imagePath, width,height);
// compressing the image
ByteArrayOutputStream baos = new ByteArrayOutputStream();
image.compress(Bitmap.CompressFormat.JPEG, 40, baos);
// encode image
String encodedImage = Base64.encodeToString(baos.toByteArray(),Base64.DEFAULT));
