Multiple Images from Gallery convert to PDF

Hi can someone help me how can I add to pdf the selected images from gallery? I already have working code but it can only convert one bitmap.

float hight = displaymetrics.heightPixels ;
float width = displaymetrics.widthPixels ;
int convertHighet = (int) hight, convertWidth = (int) width;
PdfDocument document = new PdfDocument();
PdfDocument.PageInfo pageInfo = new PdfDocument.PageInfo.Builder(bitmap.getWidth(), bitmap.getHeight(), 1).create();
PdfDocument.Page page = document.startPage(pageInfo);
Canvas canvas = page.getCanvas();

paint.setColor(Color.parseColor("#ffffff"));
canvas.drawPaint(paint);
bitmap = Bitmap.createScaledBitmap(bitmap, bitmap.getWidth(), bitmap.getHeight(), true);
paint.setColor(Color.BLUE);
canvas.drawBitmap(bitmap, 0, 0 , null);
document.finishPage(page);
// write the document content

Android studio - can't manage to detect faces using OpenCV from pictures from my gallery

I'm trying to use opencv to detect faces in static pictures from my gallery but i can't manage to detect them (or draw rectangles on the picture). I have tried a lot of things, none of which worked for me. Help would be appreciated.
I have tried changing approaches to detecting the faces, none of which worked.
Logically everything seems fine I think: choose image from gallery ---> detectFaces function ---> setting height and width to each Mat i currently have, converting the imageView's image from bitmap to Mat, so i can work on the Mat to detect the faces and then later convert the Mat back to bitmap to see the results on the imageview (imgview.setImageBitmap(bm)).
public class GalleryDetection extends AppCompatActivity {

Expected result: Image's faces are surrounded by rectangles
Actual result: Image showing without any rectangles

[][1[After Doing this changes Working fine this code.
I got Image's faces are surrounded by rectangles
Note:-
1.In Android Studio, go to File > New > Import-Module and the choose /sdk and wait for the sync to finish.
2.Do not import /sdk/java like most tutorials suggest.

android:name="android.support.FILE_PROVIDER_PATHS"

</provider>
I have seen some posts like this by I don't understands it. or it didn't help me with my problem.
The error in the logs are pointing to :
getContentResolver().openFileDescriptor(uri, "r");
Also the data returned in onActivityResult from the camera is always null.
I think the problem is I have to implement OpenFile method in my custom contentProvider but the problem I don't know what to write in that method.
Or the getUriForFile return wrong uri.
Please help me I'm in this problem for two weeks now and it seems I'm not going anywhere.
And I'm new to contentProvider.
Thanks in Advance And happy coding !

To improve the image quality you should change compression to PNG, or change the second parameters to 100 (PNG is lossless and will ignore second params).
b.compress(Bitmap.CompressFormat.PNG, 100, out);
To change external into internal just change
File outputFile = new File(Environment.getExternalStorageDirectory(), "photo_" + currentDate + ".jpg");
into
File outputFile = new File(context.getFilesDir(), "photo_" + currentDate + ".jpg");

The image you are trying to save returns you jest the thumbnail of the actual image that is why you are getting low quality image. You should pass the image name to the intent to save the high quality image when it is captured

Cropping an image in android

I am using the takePicture function in the Camera to continuously take and store pictures on a tablet. I need to know how I can crop the data that is stored upon calling takePicture. Or, if that is not possible, then I need to know how I can read in an image and then use something else to crop it. So far the only solutions I've found to this problem require opening another app to crop. Any help is appreciated.

You can try below code to crop the image:
final String Path = "sdcard/test.jpg";
Bitmap bitmap = BitmapFactory.decodeFile(Path);
ivSign.setImageBitmap(Bitmap.createScaledBitmap(bitmap, 150, 150, true));
Intent cropIntent = new Intent("com.android.camera.action.CROP");
// indicate image type and Uri
cropIntent.setDataAndType(Uri.fromFile(new File(Path)), "image/*");
// set crop properties
cropIntent.putExtra("crop", "true");
// indicate aspect of desired crop
cropIntent.putExtra("aspectX", 1);
cropIntent.putExtra("aspectY", 1);
// indicate output X and Y
cropIntent.putExtra("outputX", 256);
cropIntent.putExtra("outputY", 256);
// retrieve data on return
cropIntent.putExtra("return-data", true);
// start the activity - we handle returning in onActivityResult
startActivityForResult(cropIntent, 1);

From the Below Code you will get correct Idea. sometimes you will get
Problems if the device is like Samsung Galaxy S3 and you wants to crop image after capturing as they
are returning null intent after capturing image.
After spending hours on this issue i finally make it work by Below Way if some one is having this problem in future.
