I am capturing the image from camera. The captured image's size shows too small when captured. But later if I check in gallery the captured image size shows in MB.
I tried debugging the code, so while debugging I checked length of the file after image is captured the length shows 26956 bytes, and when I checked same image in gallery the size of the image is 1.3 MB.
Why the image size shows reduced when captured?
private void cameraIntent() {
Intent intent = new Intent(MediaStore.ACTION_IMAGE_CAPTURE);
startActivityForResult(intent, REQUEST_CAMERA);
}
private void onCaptureImageResult(Intent data) {
Bitmap thumbnail = (Bitmap) data.getExtras().get("data");
ByteArrayOutputStream bytes = new ByteArrayOutputStream();
(thumbnail.getWidth()/2),(int)(thumbnail.getHeight()/2),true);
thumbnail.compress(Bitmap.CompressFormat.PNG, 100, bytes);
File destination = new File(Environment.getExternalStorageDirectory(),
System.currentTimeMillis() + ".png");
FileOutputStream fo;
try {
destination.createNewFile();
fo = new FileOutputStream(destination);
fo.write(bytes.toByteArray());
fo.close();
} catch (FileNotFoundException e) {
e.printStackTrace();
} catch (IOException e) {
e.printStackTrace();
}
long size = destination.length();// here size of the image is too small
selectFile = false;
loadImageFromFile(destination.getAbsolutePath());
}
public void loadImageFromFile(String imageFile) {
try {
ExifInterface ei = new ExifInterface(imageFile);
int orientation = ei.getAttributeInt(ExifInterface.TAG_ORIENTATION,
ExifInterface.ORIENTATION_UNDEFINED);
Bitmap bitmap = BitmapFactory.decodeFile(imageFile);
Bitmap rotatedBitmap = null;
switch (orientation) {
case ExifInterface.ORIENTATION_ROTATE_90:
rotatedBitmap = rotateImage(bitmap, 90);
break;
case ExifInterface.ORIENTATION_ROTATE_180:
rotatedBitmap = rotateImage(bitmap, 180);
break;
case ExifInterface.ORIENTATION_ROTATE_270:
rotatedBitmap = rotateImage(bitmap, 270);
break;
case ExifInterface.ORIENTATION_NORMAL:
rotatedBitmap = bitmap;
break;
default:
rotatedBitmap = bitmap;
break;
}
if (rotatedBitmap != null) {
if (selectFile && fileSizeInKB > 500) {
rotatedBitmap = Bitmap.createScaledBitmap(rotatedBitmap, (int) (rotatedBitmap.getWidth() * 0.3), (int) (rotatedBitmap.getHeight() * 0.3), true);
}
else if(selectFile && fileSizeInKB > 1024){
rotatedBitmap = Bitmap.createScaledBitmap(rotatedBitmap, (int) (rotatedBitmap.getWidth() * 0.2), (int) (rotatedBitmap.getHeight() * 0.2), true);
}
else if(selectFile && fileSizeInMB > 2){
rotatedBitmap = Bitmap.createScaledBitmap(rotatedBitmap, (int) (rotatedBitmap.getWidth() * 0.1), (int) (rotatedBitmap.getHeight() * 0.1), true);
}
profileImageView.setImageBitmap(rotatedBitmap);
selectedBitmap = rotatedBitmap;
ByteArrayOutputStream stream = new ByteArrayOutputStream();
selectedBitmap.compress(Bitmap.CompressFormat.PNG, 100, stream); //replace 100 with desired quality percentage.
byte[] byteArray = stream.toByteArray();
File tempFile = File.createTempFile("temp", null, getCacheDir());
FileOutputStream fos = new FileOutputStream(tempFile);
fos.write(byteArray);
Long size = tempFile.length();
profileImage = tempFile;
}
} catch (IOException ex) {
}
}
I am scaling the images selected from gallery, I too want to scale the images captured from camera, but the size of the image I am not getting appropriate.
Can anyone help for this please? Thank you...

Now with this code, when I capture the image after capturing it takes time to load on image view and show blank screen till the image is set to the image view.
You are using the Thumbnail instead of the actual image.
To get the actual image you have to pass Image file uri to the Camera intent as MediaStore.EXTRA_OUTPUT
Sample :
Intent intent = new Intent(MediaStore.ACTION_IMAGE_CAPTURE);
intent.putExtra(MediaStore.EXTRA_OUTPUT, photoURI);//photoURI - file uri where you want the image to be saved
startActivityForResult(intent, REQUEST_CAMERA);
Refer https://developer.android.com/training/camera/photobasics.html#TaskPath for the required steps and complete code.
To get a scaled Bitmap from file path
int targetW = 800;
int targetH = 1000;
// Get the dimensions of the bitmap
BitmapFactory.Options bmOptions = new BitmapFactory.Options();
bmOptions.inJustDecodeBounds = true;
BitmapFactory.decodeFile(imagePath, bmOptions);
int photoW = bmOptions.outWidth;
int photoH = bmOptions.outHeight;
int scaleFactor = Math.min(photoW / targetW, photoH / targetH);
// Decode the image file into a Bitmap
bmOptions.inJustDecodeBounds = false;
bmOptions.inSampleSize = scaleFactor;
bmOptions.inPurgeable = true;
Bitmap bitmap = BitmapFactory.decodeFile(imagePath, bmOptions);
