Taking A Picture With A Camera Intent And Saving It To A File

I'm trying to get my app to start a camera intent in order to take a picture and save it into a directory as well as show a thumbnail in the main view, but I don't quite seem to ge

Solution 1:

Change your onActivityResult to

@OverridepublicvoidonActivityResult(int requestCode, int resultCode, Intent data) {
            super.onActivityResult(requestCode, resultCode, data);
            if (resultCode == Activity.RESULT_OK) {  
                    onCaptureImageResult(data);
            }
        }

for setting in a thumbnail pass the data in your ImageView variable like this:

privatevoidonCaptureImageResult(Intent data) {

        Bitmapthumbnail= (Bitmap) data.getExtras().get("data");
        ByteArrayOutputStreambytes=newByteArrayOutputStream();
        thumbnail.compress(Bitmap.CompressFormat.JPEG, 90, bytes);
        byteArray = bytes.toByteArray();
        encodedImage = Base64.encodeToString(byteArray, Base64.DEFAULT);
        Filedestination=newFile(Environment.getExternalStorageDirectory(),
                System.currentTimeMillis() + ".jpg");
        FileOutputStream fo;
        try {
            destination.createNewFile();
            fo = newFileOutputStream(destination);
            fo.write(bytes.toByteArray());
            fo.close();
        } catch (FileNotFoundException e) {
            e.printStackTrace();
        } catch (IOException e) {
            e.printStackTrace();
        }
        imageView.setImageBitmap(thumbnail);
    }

Solution 2:

NullPointerException in two different places, at photoFile.createNewFile();

use this

FilephotoFile=newFile(Environment.getExternalStorageDirectory() + File.separator + "filename");

instead of this

FilephotoFile=null;

NullPointerException in two different places, at image.setImageBitmap(imageBitmap);

just Intilize your ImageView

Solution 3:

File photoFile = null — since you are assigning null to photoFile, you will get a NullPointerException whenever you try calling methods on photoFile. You need to set photoFile to some File that is covered by your FileProvider configuration, since you are using FileProvider. Also note that you can get rid of the createNewFile() call, as that is not necessary.

And, since you are using EXTRA_OUTPUT, extras.get("data") will return null. Your image is supposed to be in the location indicated by photoFile.

Here is a sample app demonstrating the use of ACTION_IMAGE_CAPTURE with FileProvider.
