Camera Intent returns null onActivityResult

Question

I am trying to take a photo and to save it to a custom location-

public void SavePhoto(View view){

    Intent imageIntent = new Intent(android.provider.MediaStore.ACTION_IMAGE_CAPTURE);
    String timeStamp = new SimpleDateFormat("yyyyMMdd_HHmmss").format(new Date());

    File imagesFolder = new File(Environment.getExternalStorageDirectory(), "WorkingWithPhotosApp");
    imagesFolder.mkdirs();

    File image = new File(imagesFolder, "QR_" + timeStamp + ".png");
    Uri uriSavedImage = Uri.fromFile(image);

    imageIntent.putExtra(MediaStore.EXTRA_OUTPUT, uriSavedImage);
    startActivityForResult(imageIntent, REQUEST_IMAGE_CAPTURE);
}

@Override
protected void onActivityResult(int requestCode, int resultCode, Intent data) {
    if(data==null){
        Toast.makeText(MainActivity.this, "Data is null", Toast.LENGTH_SHORT).show();
    }
    else{
        if (requestCode == REQUEST_IMAGE_CAPTURE && resultCode == RESULT_OK) {
            Bundle extras = data.getExtras();
            Bitmap imageBitmap = (Bitmap) extras.get("data");
            ImageView mImageView=(ImageView)findViewById(R.id.imageView);
            mImageView.setImageBitmap(imageBitmap);
        }
    }
}

data is null in onActivityResult(). What did I miss?

Answer 1

Your preinsert a uri here:

 imageIntent.putExtra(MediaStore.EXTRA_OUTPUT, uriSavedImage);

So when you get a Activity.RESULT_OK just load the taken photo by its known url. Then you can set the path onActivityResult like below but you need to convert in to Bitmap.

if (requestCode == REQUEST_IMAGE_CAPTURE && resultCode == RESULT_OK) {
           // Convert here your uri to bitmap then set it.//
            mImageView.setImageBitmap(YOUR_BITMAP);
 }

File imagesFolder = new File(Environment.getExternalStorageDirectory(), "WorkingWithPhotosApp");

I think you need to check first either your directory exists or not. This is how I performed this task. In my case I am creating a folder in default DCIM directory.

private void dispatchTakePictureIntent(int actionCode) {
        Intent takePictureIntent = new Intent(MediaStore.ACTION_IMAGE_CAPTURE);
            File f = null;
            try {
                f = setUpPhotoFile();
                takePictureIntent.putExtra(MediaStore.EXTRA_OUTPUT, Uri.fromFile(f));
            } catch (IOException e) {
                e.printStackTrace();
                f = null;
            }
    startActivityForResult(takePictureIntent, actionCode);
    }

private File setUpPhotoFile() throws IOException {
        File f = createImageFile();
        return f;
    }

private File createImageFile() throws IOException {
        // Create an image file name
        String timeStamp = new SimpleDateFormat("yyyyMMdd_HHmmss").format(new Date());
        String imageFileName = "IMG_" + timeStamp + "_";
        File albumF = getAlbumDir();
        File imageF = File.createTempFile(imageFileName, ".jpg", albumF);
        return imageF;
    }

private File getAlbumDir() {
        File storageDir = null;
        if (Environment.MEDIA_MOUNTED.equals(Environment.getExternalStorageState())) {
            storageDir = getAlbumStorageDir(PHOTO_ALBUM_NAME);
            if (storageDir != null) {
                if (! storageDir.mkdirs()) {
                    if (! storageDir.exists()){
                        Log.d("Camera", "failed to create directory");
                        return null;
                    }
                }
            }
        } else {
            Log.v(getString(R.string.app_name), "External storage is not mounted READ/WRITE.");
        }
        return storageDir;
    }

public File getAlbumStorageDir(String albumName) {
        return new File (
                Environment.getExternalStorageDirectory()
                        + "/dcim/"
                        + albumName);
    }

Hope this helps!
