Question

I am using a onClick over a button to capture an image.

PictureCallback myPictureCallback_JPG = new PictureCallback() {

    @Override
    public void onPictureTaken(byte[] arg0, Camera arg1) {

        FileOutputStream outStream = null;
        try {
            // Write to SD Card
            outStream = new FileOutputStream(String.format("/sdcard/%d.jpg", System.currentTimeMillis())); 
            outStream.write(arg0);
            outStream.close();
            Toast.makeText(Photo.this, "Image Saved to SD Card", Toast.LENGTH_SHORT).show();
            System.out.println();
        } catch (FileNotFoundException e) { 
            e.printStackTrace();
        } catch (IOException e) {
            e.printStackTrace();
        }

        camera.startPreview();
    }};

The image gets saved in the SD card.
Then the user clicks on Send button and a layout opens, on Click of ImageView an Image Gallery opens and clicking on a particular image, the URI gets selected.

    imageAttachPhoto = (ImageView)findViewById(R.id.imageViewPhotoOne);
    imageAttachPhoto.setOnClickListener(new View.OnClickListener() {

        @Override
        public void onClick(View view) {
            Intent intent = new Intent();
            intent.setType("image/*");
            intent.setAction(Intent.ACTION_GET_CONTENT);
            startActivityForResult(Intent.createChooser(intent,"Select Picture"), SELECT_PICTURE);
        }
    });
}

public void onActivityResult(int requestCode, int resultCode, Intent data) {
    if (resultCode == RESULT_OK) {
        if (requestCode == SELECT_PICTURE) {
            Uri selectedImageUri = data.getData();
            selectedImagePath = getPath(selectedImageUri);
            System.out.println("Image Path : " + selectedImagePath);
            imageAttachPhoto.setImageURI(selectedImageUri);
        }
    }
}

public String getPath(Uri uri) {
    String[] projection = { MediaStore.Images.Media.DATA };
    Cursor cursor = managedQuery(uri, projection, null, null, null);
    int column_index = cursor.getColumnIndexOrThrow(MediaStore.Images.Media.DATA);
    cursor.moveToFirst();
    return cursor.getString(column_index);
}

But I am not able to view images snapped in Gallery code, but could see the images through FileBrowser and when I open the SD card in PC I can see the image and then the Android shows the image in Gallery also with in the code.
Let me know what the issue is and how to solve it, looking forward to your reply.
Thanks.

Answer 1

Android scan media file and those are shown when using content provider…when your run your app and take new camera at that time you just took new pics but default gallery doesn’t know about that new pics cause they are not in content provider’s list of media.

I think adding this line after taking picture and before calling gallery will show the all latest pics taken from camera.

    sendBroadcast(new Intent(Intent.ACTION_MEDIA_MOUNTED, 
                 Uri.parse("file://"+ Environment.getExternalStorageDirectory())));

This will throw a SecurityException in KitKat+. Try Vossi’s method, or use MediaScannerConnection as used here: stackoverflow – @absk
