Orientation of image from gallery is always 0

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) {}
}
}
}

Gallery images get rotated when saved

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.

Get image name from selected image in gallery

At the moment I am selecting an image from gallery and the whole path is shown example (/storage/emulated.0/DCIM/Camera/123.jpg) in the textview whereas I only want the name of the image to be shown example 123.jpg.

You need to perform a String operation.follwoing code will help you out.
String path=":/storage/sdcard0/DCIM/Camera/1414240995236.jpg";
String filename=path.substring(path.lastIndexOf("/")+1);

loading picture from library gets rotated

I am writing an android app and I am offering the user the ability to load a picture from the library.
The picture is loaded but rotated 90 degrees. Sometimes it is rotated -90 degrees.
How can I load the picture "the same way" it shows when you view it by your libray?
So if it is rotated then sure load it rotated it. But if it is correct, then it should be loaded the same way
Thank you very much
Sorry guys I should've added my code, Here it is:
try {
Intent choosePictureIntent = new Intent(Intent.ACTION_PICK, Images.Media.INTERNAL_CONTENT_URI);
startActivityForResult(choosePictureIntent, REQUEST_CHOOSE_IMAGE);
} catch (Exception e) {
e.printStackTrace();
}
break;
#Override
protected void onActivityResult(int requestCode, int resultCode, Intent imageReturnedIntent) {
super.onActivityResult(requestCode, resultCode, imageReturnedIntent);
switch(requestCode) {
case REQUEST_CHOOSE_IMAGE:
if(resultCode == RESULT_OK){
Uri selectedImage = imageReturnedIntent.getData();
InputStream imageStream;
try {
imageStream = getContentResolver().openInputStream(selectedImage);
BitmapFactory.Options options=new BitmapFactory.Options();
options.inSampleSize = 8;
Bitmap yourSelectedImage = BitmapFactory.decodeStream(imageStream, null, options );
ivPictureChosen.setImageBitmap(yourSelectedImage); //ivPictureChosen is image view to display the picture
} catch (FileNotFoundException e) {
// TODO Auto-generated catch block
e.printStackTrace();
Toast.makeText(this, "Couldn't pick image", Toast.LENGTH_SHORT).show();
}
}
}
}

I'm attempting the code below. It examines the orientation of the image and then rotates it accordingly. The issue I have is running out of memory and have yet to find a solution to exceeding the VM buget. This should work on smaller images and when your app is not already using a lot of memory.
ExifInterface ei = new ExifInterface(filePath);
int orientation = ei.getAttributeInt(
ExifInterface.TAG_ORIENTATION,
ExifInterface.ORIENTATION_NORMAL);
switch (orientation) {
case ExifInterface.ORIENTATION_ROTATE_90:
rotateBitmap(bitmap, 90);
break;
case ExifInterface.ORIENTATION_ROTATE_180:
rotateBitmap(bitmap, 180);
break;
}
public static void rotateBitmap(final Bitmap source, int mRotation){
int targetWidth=source.getWidth();
int targetHeight=source.getHeight();
Bitmap targetBitmap = Bitmap.createBitmap(targetWidth, targetHeight, source.getConfig());
Canvas canvas = new Canvas(targetBitmap);
Matrix matrix = new Matrix();
matrix.setRotate(mRotation,source.getWidth()/2,source.getHeight()/2);
canvas.drawBitmap(source, matrix, new Paint());
}

set orientation of android camera started with intent ACTION_IMAGE_CAPTURE [duplicate]

This question already has answers here:
Why does an image captured using camera intent gets rotated on some devices on Android?
(23 answers)
Closed 4 years ago.
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);
startActivityForResult(camera,1);
public void onActivityResult(int requestCode, int resultCode, Intent data){
super.onActivityResult(requestCode, resultCode, data);
switch(requestCode){
case 1:
if (resultCode == Activity.RESULT_OK) {
selectedImage = imageUri;
getContentResolver().notifyChange(selectedImage, null);
image= (ImageView) findViewById(R.id.imageview);
ContentResolver cr = getContentResolver();
Bitmap bitmap;
try {
bitmap = android.provider.MediaStore.Images.Media
.getBitmap(cr, selectedImage);
image.setImageBitmap(bitmap);
Toast.makeText(this, selectedImage.toString(),
Toast.LENGTH_LONG).show();
} catch (Exception e) {
Toast.makeText(this, "Failed to load", Toast.LENGTH_SHORT)
.show();
Log.e("Camera", e.toString());
}
}
else
if(resultCode == Activity.RESULT_CANCELED) {
Toast.makeText(EditPhoto.this, "Picture could not be taken.", Toast.LENGTH_SHORT).show();
}
}
}
The problem is that all the photos that are taken are rotated with 90 degrees-horizontally aligned.
I've also put this into my manifest file:
<activity android:name=".EditPhoto">
android:screenOrientation="portrait"
</activity>
But still with no result!So can anyone help me???

http://developer.android.com/reference/android/media/ExifInterface.html
http://developer.android.com/reference/android/media/ExifInterface.html#TAG_ORIENTATION
So if in
Activity.onActivityResult(data, request, result) {
if (request == PHOTO_REQUEST && result == RESULT_OK) {
...
Uri imageUri = ...
File imageFile = new File(imageUri.toString());
ExifInterface exif = new ExifInterface(imageFile.getAbsolutePath());
int orientation = exif.getAttributeInt(ExifInterface.TAG_ORIENTATION, ExifInterface.ORIENTATION_NORMAL);
int rotate = 0;
switch(orientation) {
case ExifInterface.ORIENTATION_ROTATE_270:
rotate-=90;
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;
}
