I am selecting an image from gallery and showing it on a image view. Image is getting selected, but on samsung phones it has issue of rotating the image so to solve that I am checking if the image is rotated or not usif EXIF interface and if rotated change its angle.
But this is not working for some images. Some images I can see straight, but some images if they are straight then also they are getting rotate.
As I did debug the orientation for the image is 0, it goes in the default case and applies normal bitmap to the rotated bitmap. Still the image I see is rotated. Not getting why is this happening..
private void onSelectFromGalleryResult(Intent data) {
Bitmap bm=null;
if (data != null) {
try {
bm = MediaStore.Images.Media.getBitmap(getApplicationContext().getContentResolver(), data.getData());
} catch (IOException e) {
e.printStackTrace();
}
}
ByteArrayOutputStream bytes = new ByteArrayOutputStream();
bm = Bitmap.createScaledBitmap(bm,512,512, true);
bm.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();
}
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;
Log.e("orientation",String.valueOf(orientation)+" check");
switch (orientation) {
case ExifInterface.ORIENTATION_ROTATE_90:
rotatedBitmap = rotateImage(bitmap, 90);
Log.e("orientation",String.valueOf(orientation)+" check");
break;
case ExifInterface.ORIENTATION_ROTATE_180:
rotatedBitmap = rotateImage(bitmap, 180);
Log.e("orientation",String.valueOf(orientation)+" check");
break;
case ExifInterface.ORIENTATION_ROTATE_270:
rotatedBitmap = rotateImage(bitmap, 270);
Log.e("orientation",String.valueOf(orientation)+" check");
break;
case ExifInterface.ORIENTATION_NORMAL:
rotatedBitmap = bitmap;
Log.e("orientation",String.valueOf(orientation)+" check");
break;
default:
rotatedBitmap = bitmap;
Log.e("orientation",String.valueOf(orientation)+" check");
break;
}
if(rotatedBitmap != null)
{
profile_image.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);
mProfileImage = tempFile;
}
}
catch (IOException ex) {
// UiUtils.showAlert(getString(R.string.error),NewGroupAcvitity.this);
}
}
public static Bitmap rotateImage(Bitmap source, float angle) {
Matrix matrix = new Matrix();
matrix.postRotate(angle);
return Bitmap.createBitmap(source, 0, 0, source.getWidth(), source.getHeight(), matrix,
true);

@greenapps - use selected file like this? I tried this, but this was not working in xiaomi devices so I changed the code. Is there any other way for other devices?
What's going wrong here? Can anyone help please? Thank you.
