I'm trying to load an image from gallery in a ImageView. This code work correctly on Huawei p10, but don't work correctly on Samsung s5 and other devices. When i load the image the orientation is not correctly.
I'm using this function to load from gallery but the orientation is always 0.
public void loadPostImage(View v) {
Intent intent = new Intent();
intent.setType("image/*");
intent.setAction(Intent.ACTION_GET_CONTENT);
startActivityForResult(Intent.createChooser(intent, "Select Picture"), SELECT_PICTURE1);
}
protected void onActivityResult(int requestCode, int resultCode, Intent data) {
if (resultCode == RESULT_OK) {
if (requestCode == SELECT_PICTURE1) {
selectedImageUri = data.getData();
if (null != selectedImageUri) {
flag=true;
path = selectedImageUri.getPath();
int orientation = getOrientation(getApplicationContext(), selectedImageUri);
Log.e("image path", path + "");
image_post.setImageURI(selectedImageUri);
}
}
}
}
private static int getOrientation(Context context, Uri photoUri) {
Cursor cursor = context.getContentResolver().query(photoUri,
new String[]{MediaStore.Images.ImageColumns.ORIENTATION}, null, null, null);
if (cursor.getCount() != 1) {
cursor.close();
return -1;
}
cursor.moveToFirst();
int orientation = cursor.getInt(0);
cursor.close();
cursor = null;
return orientation;
}
I tried also with EXIF. But nothing is changed.
public void controlRotate(Uri photoUri) throws IOException {
ExifInterface exif = new ExifInterface(photoUri.getPath());
int exifRotation = exif.getAttributeInt(ExifInterface.TAG_ORIENTATION,
ExifInterface.ORIENTATION_UNDEFINED);
switch (exifRotation) {
case ExifInterface.ORIENTATION_ROTATE_90: {
float photoRotation = 90.0f;
break;
}
case ExifInterface.ORIENTATION_ROTATE_180: {
float photoRotation = 180.0f;
break;
}
case ExifInterface.ORIENTATION_ROTATE_270: {
float photoRotation = 270.0f;
break;
}
}
}
I resolved the problem using this snippet
public void orientation(Uri selectedImageUri){
Uri uri = selectedImageUri; // the URI you've received from the other app
InputStream in = null;
try {
in = getContentResolver().openInputStream(uri);
ExifInterface exifInterface = new ExifInterface(in);
int rotation = 0;
int orientation = exifInterface.getAttributeInt(
ExifInterface.TAG_ORIENTATION,
ExifInterface.ORIENTATION_NORMAL);
switch (orientation) {
case ExifInterface.ORIENTATION_ROTATE_90:
rotation = 90;
break;
case ExifInterface.ORIENTATION_ROTATE_180:
rotation = 180;
break;
case ExifInterface.ORIENTATION_ROTATE_270:
rotation = 270;
break;
}
// Now you can extract any Exif tag you want
// Assuming the image is a JPEG or supported raw format
} catch (IOException e) {
// Handle any errors
} finally {
if (in != null) {
try {
in.close();
} catch (IOException ignored) {}
}
}
}

I have been trying to save images to Firebase Storage but I noticed that almost all pictures saved from Gallery/Google Drive get rotated.(usually by 90 degrees)
Reading through older posts I realized that this is a common issue and I tried solving it by trying either solution from this post , or from this one , this one and I could go on.
After roughly 8 hours I finally decided to ask here. Is there a better and easier implementation to stop the images from getting rotated?
My last (and unsuccessful, obviously) implementation using ExifInterface (which returns all the time 0) is this one:
Selecting picture
Intent intent = new Intent();
intent.setType("image/*");
intent.setAction(Intent.ACTION_PICK);
startActivityForResult(Intent.createChooser(intent, "Select Picture"), PICK_IMAGE_REQUEST);
OnActivityResult
#Override
public void onActivityResult(int requestCode, int resultCode, Intent data) {
super.onActivityResult(requestCode, resultCode, data);
if (requestCode == PICK_IMAGE_REQUEST && resultCode == RESULT_OK && data != null && data.getData() != null) {
Uri selectedImage = data.getData();
String[] filePathColumn = {MediaStore.Images.Media.DATA};
Cursor cursor = getContext().getContentResolver().query(selectedImage, filePathColumn, null, null, null);
cursor.moveToFirst();
int columnIndex = cursor.getColumnIndex(filePathColumn[0]);
String filePath = cursor.getString(columnIndex);
cursor.close();
int rotateImageAngle = getPhotoOrientation(getContext(), selectedImage, filePath);
try {
bitmap = MediaStore.Images.Media.getBitmap(getContext().getContentResolver(), selectedImage);
// Log.d(TAG, String.valueOf(bitmap));
addPictureButton.setText("Done");
} catch (IOException e) {
e.printStackTrace();
}
if( bitmap != null)
{
RotateBitmap(bitmap , rotateImageAngle);
}
}
Helper methods
public int getPhotoOrientation(Context context, Uri imageUri, String imagePath){
int rotate = 0;
try {
context.getContentResolver().notifyChange(imageUri, null);
File imageFile = new File(imagePath);
ExifInterface exif = new ExifInterface(imageFile.getAbsolutePath());
int orientation = exif.getAttributeInt(ExifInterface.TAG_ORIENTATION, ExifInterface.ORIENTATION_NORMAL);
switch (orientation) {
case ExifInterface.ORIENTATION_ROTATE_270:
rotate = 270;
break;
case ExifInterface.ORIENTATION_ROTATE_180:
rotate = 180;
break;
case ExifInterface.ORIENTATION_ROTATE_90:
rotate = 90;
break;
}
Log.i("RotateImage", "Exif orientation: " + orientation);
Log.i("RotateImage", "Rotate value: " + rotate);
} catch (Exception e) {
e.printStackTrace();
}
return rotate;
}
public static Bitmap RotateBitmap(Bitmap source, int angle)
{
Matrix matrix = new Matrix();
matrix.postRotate(angle);
return Bitmap.createBitmap(source, 0, 0, source.getWidth(), source.getHeight(), matrix, true);
}
Note: If needed I will add the code that uploads images to Firebase
I have come to a solution thanks to this post.
I am going to post below a modified working version of the code for anybody that has this issue.
Fire up picture selection from gallery
Intent intent = new Intent(Intent.ACTION_PICK,
android.provider.MediaStore.Images.Media.EXTERNAL_CONTENT_URI);
intent.setType("image/*");
startActivityForResult(intent, PICK_IMAGE_REQUEST);
OnActivityResult checking original roatation of the selected picture
public void onActivityResult(int requestCode, int resultCode, Intent data) {
super.onActivityResult(requestCode, resultCode, data);
if (resultCode == Activity.RESULT_OK && requestCode == PICK_IMAGE_REQUEST) {
// Get selected gallery image
Uri selectedPicture = data.getData();
// Get and resize profile image
String[] filePathColumn = {MediaStore.Images.Media.DATA};
// TRY getactvity() as well if not work
Cursor cursor = getContext().getContentResolver().query(selectedPicture, filePathColumn, null, null, null);
cursor.moveToFirst();
int columnIndex = cursor.getColumnIndex(filePathColumn[0]);
String picturePath = cursor.getString(columnIndex);
cursor.close();
loadedBitmap = BitmapFactory.decodeFile(picturePath);
ExifInterface exif = null;
try {
File pictureFile = new File(picturePath);
exif = new ExifInterface(pictureFile.getAbsolutePath());
} catch (IOException e) {
e.printStackTrace();
}
int orientation = ExifInterface.ORIENTATION_NORMAL;
if (exif != null)
orientation = exif.getAttributeInt(ExifInterface.TAG_ORIENTATION, ExifInterface.ORIENTATION_NORMAL);
switch (orientation) {
case ExifInterface.ORIENTATION_ROTATE_90:
loadedBitmap = rotateBitmap(loadedBitmap, 90);
break;
case ExifInterface.ORIENTATION_ROTATE_180:
loadedBitmap = rotateBitmap(loadedBitmap, 180);
break;
case ExifInterface.ORIENTATION_ROTATE_270:
loadedBitmap = rotateBitmap(loadedBitmap, 270);
break;
}
imageView.setImageBitmap(loadedBitmap);
}
}
RotateBitmap method
public static Bitmap rotateBitmap(Bitmap bitmap, int degrees) {
Matrix matrix = new Matrix();
matrix.postRotate(degrees);
return Bitmap.createBitmap(bitmap, 0, 0, bitmap.getWidth(), bitmap.getHeight(), matrix, true);

and it works but it gives me this error: if I take a photo like this:
it loads a picture in imageview in this way:
but if I load the picture from the gallery, it works ok.
What's the error here?

You have to rotate image using ExifInterface.
Image rotate based on image capture angle.
ExifInterface will rotate image even if you click photo from any angle.
It will display properly.
File mediaFile = new File(mediaPath);
Bitmap bitmap;
if (mediaFile.exists()) {
if (isImage(mediaPath)) {
Bitmap myBitmap = BitmapFactory.decodeFile(mediaFile.getAbsolutePath());
int height = (myBitmap.getHeight() * 512 / myBitmap.getWidth());
Bitmap scale = Bitmap.createScaledBitmap(myBitmap, 512, height, true);
int rotate = 0;
try {
exif = new ExifInterface(mediaFile.getAbsolutePath());
} catch (IOException e) {
// TODO Auto-generated catch block
e.printStackTrace();
}
int orientation = exif.getAttributeInt(ExifInterface.TAG_ORIENTATION,
ExifInterface.ORIENTATION_UNDEFINED);
switch (orientation) {
case ExifInterface.ORIENTATION_NORMAL:
rotate = 0;
break;
case ExifInterface.ORIENTATION_ROTATE_270:
rotate = 270;
break;
case ExifInterface.ORIENTATION_ROTATE_180:
rotate = 180;
break;
case ExifInterface.ORIENTATION_ROTATE_90:
rotate = 90;
break;
}
Matrix matrix = new Matrix();
matrix.postRotate(rotate);
Bitmap rotateBitmap = Bitmap.createBitmap(scale, 0, 0, scale.getWidth(),
scale.getHeight(), matrix, true);
displayImage.setImageBitmap(rotateBitmap);
}
}
public static boolean isImage(String str) {
boolean temp = false;
String[] arr = { ".jpeg", ".jpg", ".png", ".bmp", ".gif" };
for (int i = 0; i < arr.length; i++) {
temp = str.endsWith(arr[i]);
if (temp) {
break;
}
}
return temp;
}
I am using the following code to get the orientation of the selected image so that if it was taken vertically, when selected from gallery it would not be shown horizontally.
The error is occuring in the
File imageFile = new File(selectedImage.toString()); in the parameter selectedImage.toString()) since when I changed the initial int rotate=90 and chose a vertical image the result was good.
Am I passing the parameter to the File correct?

for image handling compile picasso is best library using it you can easily handle images using it you can load image from cache also and increase performance of your app so try to avoid doing lots of code and add following line in your build gradle and then use picasso in your code.
compile 'com.squareup.picasso:picasso:2.5.0'
I have been stuck in camera for 6 days but not getting any proper solution. When I am capturing image through camera intent, image is being rotated.

I am getting image in landscape mode but not in potrait mode. Camera preview automatically rotates by 90 degrees after capturing image.
It is because of the image's EXIF data. You need to use a rotation method.
Depending on your build-in Camera orientation and orientation of device the pictures will have different rotations. You check the rotation of your particular image through ExifInterface.
/**
* #param filename Path to image file
* #param captureTime Time when image file was created
*/
public static int extractExifOrientationTagFromImageFile(String filename, long creationTime) {
/* The issue is on some devices, there's a bug that makes the picture taken saved in your app folder without proper
exif tags while a properly rotated image is saved in the android default folder (even though it shouldn't be).
Now what we do is recording the time when we're starting the camera app. Then we query
the Media Provider to see if any pictures were saved after this timestamp we've saved. That means most likely Android OS
saved the properly rotated picture in the default folder and of course put an entry in the media store and we can use the
rotation information from this row. */
int imageRotation = -1;
long imageFileSize = new File(filename).length();
Cursor mediaFileCursor = getContext().getContentResolver().query(MediaStore.Images.Media.EXTERNAL_CONTENT_URI,
new String[] { MediaStore.Images.ImageColumns.ORIENTATION, MediaStore.MediaColumns.SIZE },

// Extra check to make sure that we are getting the orientation from the proper file
if(mediaFileSize == imageFileSize) {

break;
}
}
}

I'm working at an application in android which uses camera to take photos.For starting the camera I'm using an intent ACTION_IMAGE_CAPTURE like this:
Intent camera = new Intent(MediaStore.ACTION_IMAGE_CAPTURE);
File image=new File(Environment.getExternalStorageDirectory(),"PhotoContest.jpg");
camera.putExtra(MediaStore.EXTRA_OUTPUT,Uri.fromFile(image));
imageUri=Uri.fromFile(image);

case ExifInterface.ORIENTATION_ROTATE_180:
rotate-=90;
case ExifInterface.ORIENTATION_ROTATE_90:
rotate-=90;
}
Canvas canvas = new Canvas(bitmap);
canvas.rotate(rotate);
}
Does this help at all?
Just to add to Greg's great answer, here's a whole "category" to do the job:
public static int neededRotation(File ff)
{
try
{
ExifInterface exif = new ExifInterface(ff.getAbsolutePath());
int orientation = exif.getAttributeInt(
ExifInterface.TAG_ORIENTATION, ExifInterface.ORIENTATION_NORMAL);
if (orientation == ExifInterface.ORIENTATION_ROTATE_270)
{ return 270; }
if (orientation == ExifInterface.ORIENTATION_ROTATE_180)
{ return 180; }
if (orientation == ExifInterface.ORIENTATION_ROTATE_90)
{ return 90; }
return 0;
} catch (FileNotFoundException e)
{
e.printStackTrace();
} catch (IOException e)
{
e.printStackTrace();
}
return 0;
}
you'd use it more or less like this ...
public void onActivityResult(int requestCode, int resultCode, Intent data)
{
if (requestCode == REQUEST_IMAGE_CAPTURE) // && resultCode == RESULT_OK )
{
try
{
Bitmap cameraBmp = MediaStore.Images.Media.getBitmap(
State.mainActivity.getContentResolver(),
Uri.fromFile( Utils.tempFileForAnImage() ) );
cameraBmp = ThumbnailUtils.extractThumbnail(cameraBmp, 320,320);
// NOTE incredibly useful trick for cropping/resizing square
// http://stackoverflow.com/a/17733530/294884
Matrix m = new Matrix();
m.postRotate( Utils.neededRotation(Utils.tempFileForAnImage()) );
cameraBmp = Bitmap.createBitmap(cameraBmp,
0, 0, cameraBmp.getWidth(), cameraBmp.getHeight(),
m, true);
yourImageView.setImageBitmap(cameraBmp);
// to convert to bytes...
ByteArrayOutputStream baos = new ByteArrayOutputStream();
cameraBmp.compress(Bitmap.CompressFormat.JPEG, 75, baos);
//or say cameraBmp.compress(Bitmap.CompressFormat.PNG, 0, baos);
imageBytesRESULT = baos.toByteArray();
} catch (FileNotFoundException e)
{
e.printStackTrace();
} catch (IOException e)
{
e.printStackTrace();
}
return;
}
}
Hope it saves someone some typing in the future.
The above answer is very thorough, but I found I had to do a little bit more in order for every case to work, especially if you're dealing with images from other sources such as the Gallery or Google Photos. Here's my DetermineOrientation method. I have a utility class where this is located so I have to pass in the Activity in order to use managedQuery(which btw is deprecated so use cautiously). The reason I have to use two methods is because, depending on the source of the image, ExifInterface will not work. For instance, if I take a camera photo, Exif works fine. However, if I'm also choosing images from the Gallery or Google Drive, Exif does not work and always returns 0. Hope this helps someone.
public static int DetermineOrientation(Activity activity, Uri fileUri)
{
int orientation = -1;
int rotate = 0;
try {
ExifInterface exif = new ExifInterface(fileUri.getPath());
orientation = exif.getAttributeInt(
ExifInterface.TAG_ORIENTATION, ExifInterface.ORIENTATION_NORMAL);
rotate = 0;
switch (orientation) {
case ExifInterface.ORIENTATION_ROTATE_270:
rotate = 270;
case ExifInterface.ORIENTATION_ROTATE_180:
rotate = 180;
case ExifInterface.ORIENTATION_ROTATE_90:
rotate = 90;
}
} catch (FileNotFoundException e) {
e.printStackTrace();
} catch (IOException e) {
e.printStackTrace();
}
if(rotate == 0)
{
String[] orientationColumn = {MediaStore.Images.Media.ORIENTATION};
Cursor cur = activity.managedQuery(fileUri, orientationColumn, null, null, null);
orientation = -1;
if (cur != null && cur.moveToFirst()) {
orientation = cur.getInt(cur.getColumnIndex(orientationColumn[0]));
}
if(orientation != -1)
{
rotate = orientation;
}
}
return rotate;
}
