Capture Image from Camera and Display in Activity

Question

I want to write a module where on a click of a button the camera opens and I can click and capture an image   If I don t like the image I can delete it and click one more image and then select the image and it should return back and display that image in the activity

I know it s a quite old thread  but all these solutions are not completed and don t work on some devices when user rotates camera because data in onActivityResult is null  So here is solution which I have tested on lots of devices and haven t faced any problem so far   First declare your Uri variable in your activity   private Uri uriFilePath    Then create your temporary folder for storing captured image and make intent for capturing image by camera   PackageManager packageManager   getActivity   getPackageManager    if  packageManager hasSystemFeature PackageManager FEATURE CAMERA         File mainDirectory   new File Environment getExternalStorageDirectory     MyFolder tmp             if   mainDirectory exists                 mainDirectory mkdirs               Calendar calendar   Calendar getInstance               uriFilePath   Uri fromFile new File mainDirectory   IMG     calendar getTimeInMillis                intent   new Intent MediaStore ACTION IMAGE CAPTURE             intent putExtra MediaStore EXTRA OUTPUT  uriFilePath             startActivityForResult intent  1       And now here comes one of the most important things  you have to save your uriFilePath in onSaveInstanceState  because if you didn t do that and user rotated his device while using camera  your uri would be null    Override protected void onSaveInstanceState Bundle outState         if  uriFilePath    null           outState putString  uri file path   uriFilePath toString          super onSaveInstanceState outState       After that you should always recover your uri in your onCreate method    Override protected void onCreate Bundle savedInstanceState        super onCreate savedInstanceState       if  savedInstanceState    null             if  uriFilePath    null  amp  amp  savedInstanceState getString  uri file path      null                 uriFilePath   Uri parse savedInstanceState getString  uri file path                           And here comes last part to get your Uri in onActivityResult    Override protected void onActivityResult int requestCode  int resultCode  Intent data            if  resultCode    RESULT OK             if  requestCode    1                String filePath   uriFilePath getPath       Here is path of your captured image  so you can create bitmap from it  etc                        P S  Don t forget to add permissions for Camera and Ext  storage writing to your Manifest

I created a dialog with the option to choose Image from gallery or camera  with a callback as  Uri if the image is from the gallery String as a file path if the image is captured from the camera  Image as File the image chosen from camera needs to be uploaded on the internet as Multipart file data  At first we to define permission in AndroidManifest as we need to write external store while creating a file and reading images from gallery  lt uses-permission android name  quot android permission WRITE EXTERNAL STORAGE quot    gt   lt uses-permission android name  quot android permission READ EXTERNAL STORAGE quot    gt   Create a file paths xml in app src main res xml file paths xml with path  lt  xml version  quot 1 0 quot  encoding  quot utf-8 quot   gt   lt paths xmlns android  quot http   schemas android com apk res android quot  gt       lt external-path name  quot external files quot  path  quot   quot   gt   lt  paths gt   Then we need to define file provier to generate

You can use custom camera with thumbnail image  You can look my project

You need to read up about the Camera    I think to do what you want  you d have to save the current image to your app  do the select delete there  and then recall the camera to try again  rather than doing the retry directly inside the camera

Update  2020   Google has added a new ActivityResultRegistry API that  lets you handle the startActivityForResult     onActivityResult   as well as requestPermissions     onRequestPermissionsResult   flows without overriding methods in your Activity or Fragment  brings increased type safety via ActivityResultContract  and provides hooks for testing these flows  - source    The API was added in androidx activity 1 2 0-alpha02 and androidx fragment 1 3 0-alpha02    So you are now able to do something like   val takePicture   registerForActivityResult ActivityResultContracts TakePicture      success  Boolean - gt      if  success               The image was saved into the given Uri - gt  do something with it          val imageUri  Uri       button setOnClickListener       takePicture launch imageUri      Take a look at the documentation to learn how to use the new Activity result API  https   developer android com training basics intents result kotlin  There are many built-in ActivityResultContracts that allow you to do different things like pick contacts  request permissions  take pictures or take videos  You are probably interested in the ActivityResultContracts TakePicture shown above   Note that androidx fragment 1 3 0-alpha04 deprecates the startActivityForResult     onActivityResult   and requestPermissions     onRequestPermissionsResult   APIs on Fragment  Hence it seems that ActivityResultContracts is the new way to do things from now on     Original answer  2015   It took me some hours to get this working  The code it s almost a copy-paste from developer android com  with a minor difference   Request this permission on the AndroidManifest xml    lt uses-permission android name  android permission WRITE EXTERNAL STORAGE    gt    On your Activity  start by defining this   static final int REQUEST IMAGE CAPTURE   1  private Bitmap mImageBitmap  private String mCurrentPhotoPath  private ImageView mImageView    Then fire this Intent in an onClick   Intent cameraIntent   new Intent MediaStore ACTION IMAGE CAPTURE   if  cameraIntent resolveActivity getPackageManager       null           Create the File where the photo should go     File photoFile   null      try           photoFile   createImageFile          catch  IOException ex               Error occurred while creating the File         Log i TAG   IOException                 Continue only if the File was successfully created     if  photoFile    null            cameraIntent putExtra MediaStore EXTRA OUTPUT  Uri fromFile photoFile            startActivityForResult cameraIntent  REQUEST IMAGE CAPTURE             Add the following support method   private File createImageFile   throws IOException          Create an image file name     String timeStamp   new SimpleDateFormat  yyyyMMdd HHmmss   format new Date         String imageFileName    JPEG     timeStamp            File storageDir   Environment getExternalStoragePublicDirectory              Environment DIRECTORY PICTURES       File image   File createTempFile              imageFileName      prefix               jpg              suffix             storageDir         directory                Save a file  path for use with ACTION VIEW intents     mCurrentPhotoPath    file     image getAbsolutePath        return image      Then receive the result    Override protected void onActivityResult int requestCode  int resultCode  Intent data        if  requestCode    REQUEST IMAGE CAPTURE  amp  amp  resultCode    RESULT OK            try               mImageBitmap   MediaStore Images Media getBitmap this getContentResolver    Uri parse mCurrentPhotoPath                mImageView setImageBitmap mImageBitmap             catch  IOException e                e printStackTrace                        What made it work is the MediaStore Images Media getBitmap this getContentResolver    Uri parse mCurrentPhotoPath    which is different from the code from developer android com  The original code gave me a FileNotFoundException

Here is code I have used for Capturing and Saving Camera Image then display it to imageview  You can use according to your need   You have to save Camera image to specific location then fetch from that location then convert it to byte-array   Here is method for opening capturing camera image activity   private static final int CAMERA PHOTO   111  private Uri imageToUploadUri   private void captureCameraImage             Intent chooserIntent   new Intent MediaStore ACTION IMAGE CAPTURE           File f   new File Environment getExternalStorageDirectory     POST IMAGE jpg            chooserIntent putExtra MediaStore EXTRA OUTPUT  Uri fromFile f            imageToUploadUri   Uri fromFile f           startActivityForResult chooserIntent  CAMERA PHOTO           then your onActivityResult   method should be like this    Override         protected void onActivityResult int requestCode  int resultCode  Intent data                super onActivityResult requestCode  resultCode  data                if  requestCode    CAMERA PHOTO  amp  amp  resultCode    Activity RESULT OK                    if imageToUploadUri    null                       Uri selectedImage   imageToUploadUri                      getContentResolver   notifyChange selectedImage  null                       Bitmap reducedSizeBitmap   getBitmap imageToUploadUri getPath                         if reducedSizeBitmap    null                           ImgPhoto setImageBitmap reducedSizeBitmap                           Button uploadImageButton    Button  findViewById R id uploadUserImageButton                             uploadImageButton setVisibility View VISIBLE                                        else                          Toast makeText this  Error while capturing Image  Toast LENGTH LONG  show                                           else                      Toast makeText this  Error while capturing Image  Toast LENGTH LONG  show                                                 Here is getBitmap   method used in onActivityResult    I have done all performance improvement that can be possible while getting camera capture image bitmap   private Bitmap getBitmap String path             Uri uri   Uri fromFile new File path            InputStream in   null          try               final int IMAGE MAX SIZE   1200000     1 2MP             in   getContentResolver   openInputStream uri                   Decode image size             BitmapFactory Options o   new BitmapFactory Options                o inJustDecodeBounds   true              BitmapFactory decodeStream in  null  o               in close                  int scale   1              while   o outWidth   o outHeight     1   Math pow scale  2    gt                      IMAGE MAX SIZE                    scale                              Log d      scale       scale      orig-width      o outWidth      orig-height      o outHeight                Bitmap b   null              in   getContentResolver   openInputStream uri               if  scale  gt  1                    scale--                     scale to max possible inSampleSize that still yields an image                    larger than target                 o   new BitmapFactory Options                    o inSampleSize   scale                  b   BitmapFactory decodeStream in  null  o                       resize to desired dimensions                 int height   b getHeight                    int width   b getWidth                    Log d      1th scale operation dimenions - width      width      height      height                    double y   Math sqrt IMAGE MAX SIZE                              double  width    height                    double x    y   height    width                   Bitmap scaledBitmap   Bitmap createScaledBitmap b   int  x                           int  y  true                   b recycle                    b   scaledBitmap                   System gc                  else                   b   BitmapFactory decodeStream in                             in close                 Log d      bitmap size - width      b getWidth        height                          b getHeight                 return b            catch  IOException e                Log e     e getMessage    e               return null                    Hope it helps
