copied!<p>Without any code is hard to tell what's going on.</p> <p>The most simple way i've found is to read the EXIF information and check if the image needs rotation. To read more on ExifInterface class on Android: <a href="http://developer.android.com/intl/es/reference/android/media/ExifInterface.html" rel="nofollow">http://developer.android.com/intl/es/reference/android/media/ExifInterface.html</a></p> <p>That said, here is some example code:</p> <pre><code>/** An URI and a imageView */ public void setBitmap(ImageView mImageView, String imageURI){ // Get the original bitmap dimensions BitmapFactory.Options options = new BitmapFactory.Options(); Bitmap bitmap = BitmapFactory.decodeFile(imageURI, options); float rotation = rotationForImage(getActivity(), Uri.fromFile(new File(imageURI))); if(rotation!=0){ //New rotation matrix Matrix matrix = new Matrix(); matrix.preRotate(rotation); mImageView.setImageBitmap(Bitmap.createBitmap(bitmap, 0, 0, reqHeight, reqWidth, matrix, true)); } else { //No need to rotate mImageView.setImageBitmap(BitmapFactory.decodeFile(imageURI, options)); } } /** Returns how much we have to rotate */ public static float rotationForImage(Context context, Uri uri) { try{ if (uri.getScheme().equals("content")) { //From the media gallery String[] projection = { Images.ImageColumns.ORIENTATION }; Cursor c = context.getContentResolver().query(uri, projection, null, null, null); if (c.moveToFirst()) { return c.getInt(0); } } else if (uri.getScheme().equals("file")) { //From a file saved by the camera ExifInterface exif = new ExifInterface(uri.getPath()); int rotation = (int) exifOrientationToDegrees(exif.getAttributeInt(ExifInterface.TAG_ORIENTATION, ExifInterface.ORIENTATION_NORMAL)); return rotation; } return 0; } catch (IOException e) { Log.e(TAG, "Error checking exif", e); return 0; } } /** Get rotation in degrees */ private static float exifOrientationToDegrees(int exifOrientation) { if (exifOrientation == ExifInterface.ORIENTATION_ROTATE_90) { return 90; } else if (exifOrientation == ExifInterface.ORIENTATION_ROTATE_180) { return 180; } else if (exifOrientation == ExifInterface.ORIENTATION_ROTATE_270) { return 270; } return 0; } </code></pre> <p>If there is an error you will see the log "Error checking EXIF" on rotationForImage function.</p>
