Photos rotate 90 degrees during capture on some phones

Question

The photo rotates 90 degrees when capturing other mobile phones from the camera on the Samsung mobile phone. Please help me with this.

Intent cameraIntent = new Intent(android.provider.MediaStore.ACTION_IMAGE_CAPTURE); startActivityForResult(cameraIntent, IMAGE_CAPTURE); @Override protected void onActivityResult(int requestCode, int resultCode, Intent data) { super.onActivityResult(requestCode, resultCode, data); try { if (requestCode == IMAGE_CAPTURE) { if (resultCode == RESULT_OK){ Uri contentUri = data.getData(); if(contentUri!=null) { String[] proj = { MediaStore.Images.Media.DATA }; Cursor cursor = managedQuery(contentUri, proj, null, null, null); int column_index = cursor.getColumnIndexOrThrow(MediaStore.Images.Media.DATA); cursor.moveToFirst(); imageUri = Uri.parse(cursor.getString(column_index)); } tempBitmap = (Bitmap) data.getExtras().get("data"); mainImageView.setImageBitmap(tempBitmap); isCaptureFromCamera = true; } }

This happens as a bug in earlier versions of Android.

I solved this problem by simply getting the orientation angle and rotating the bitmap accordingly.

 public Bitmap decodeFile(String path) {//you can provide file path here int orientation; try { if (path == null) { return null; } // decode image size BitmapFactory.Options o = new BitmapFactory.Options(); o.inJustDecodeBounds = true; // Find the correct scale value. It should be the power of 2. final int REQUIRED_SIZE = 70; int width_tmp = o.outWidth, height_tmp = o.outHeight; int scale = 0; while (true) { if (width_tmp / 2 < REQUIRED_SIZE || height_tmp / 2 < REQUIRED_SIZE) break; width_tmp /= 2; height_tmp /= 2; scale++; } // decode with inSampleSize BitmapFactory.Options o2 = new BitmapFactory.Options(); o2.inSampleSize = scale; Bitmap bm = BitmapFactory.decodeFile(path, o2); Bitmap bitmap = bm; ExifInterface exif = new ExifInterface(path); orientation = exif.getAttributeInt(ExifInterface.TAG_ORIENTATION, 1); Log.e("ExifInteface .........", "rotation ="+orientation); //exif.setAttribute(ExifInterface.ORIENTATION_ROTATE_90, 90); Log.e("orientation", "" + orientation); Matrix m = new Matrix(); if ((orientation == ExifInterface.ORIENTATION_ROTATE_180)) { m.postRotate(180); //m.postScale((float) bm.getWidth(), (float) bm.getHeight()); // if(m.preRotate(90)){ Log.e("in orientation", "" + orientation); bitmap = Bitmap.createBitmap(bm, 0, 0, bm.getWidth(),bm.getHeight(), m, true); return bitmap; } else if (orientation == ExifInterface.ORIENTATION_ROTATE_90) { m.postRotate(90); Log.e("in orientation", "" + orientation); bitmap = Bitmap.createBitmap(bm, 0, 0, bm.getWidth(),bm.getHeight(), m, true); return bitmap; } else if (orientation == ExifInterface.ORIENTATION_ROTATE_270) { m.postRotate(270); Log.e("in orientation", "" + orientation); bitmap = Bitmap.createBitmap(bm, 0, 0, bm.getWidth(),bm.getHeight(), m, true); return bitmap; } return bitmap; } catch (Exception e) { return null; } }

Also request the value of MediaStore.Images.Media.ORIENTATION to get the rotation angle. Then you can rotate the image yourself or whatever.

What I do: first check the orientation of the image taken by the camera using metadata data, and if we found it in the portrait, we must rotate the image 90 and display otherwise only the display.

For information about image orientation we can use ExifInterface. What is it!
