Upload image from entire phone

Question

I have created an activity that upon button click user are able to upload a picture from their device gallery, which would get cast to an imageview. The problem is that it is only able to retrieve image from device gallery, not from phone camera gallery, or from phone google drive folder. I would want that its able to upload any picture from their phone, regardless of the source.

Below is the code:

    Button buttonLoadImage = (Button) findViewById(R.id.btnPictureSelect);
    buttonLoadImage.setOnClickListener(new View.OnClickListener() {
        @Override
        public void onClick(View arg0) {
            Intent i = new Intent(
                    Intent.ACTION_PICK,
                    android.provider.MediaStore.Images.Media.EXTERNAL_CONTENT_URI);
            startActivityForResult(i, RESULT_LOAD_IMAGE);
        }
    });

} 

    @Override
    protected void onActivityResult(int requestCode, int resultCode, Intent data) {
        super.onActivityResult(requestCode, resultCode, data);

        if (requestCode == RESULT_LOAD_IMAGE && resultCode == RESULT_OK
                && null != data) {
            Uri selectedImage = data.getData();
            String[] filePathColumn = { MediaStore.Images.Media.DATA };

            Cursor cursor = getContentResolver().query(selectedImage,
                    filePathColumn, null, null, null);
            cursor.moveToFirst();

            int columnIndex = cursor.getColumnIndex(filePathColumn[0]);
            String picturePath = cursor.getString(columnIndex);
            cursor.close();

            ImageView imageView = (ImageView) findViewById(R.id.profilePicturePreview);
            imageView.setImageBitmap(BitmapFactory.decodeFile(picturePath));

        }

    }

    private byte[] readInFile(String path) throws IOException {
        // TODO Auto-generated method stub
        byte[] data = null;
        File file = new File(path);
        InputStream input_stream = new BufferedInputStream(new FileInputStream(
                file));
        ByteArrayOutputStream buffer = new ByteArrayOutputStream();
        data = new byte[16384]; // 16K
        int bytes_read;
        while ((bytes_read = input_stream.read(data, 0, data.length)) != -1) {
            buffer.write(data, 0, bytes_read);
        }
        input_stream.close();
        return buffer.toByteArray();

    }

Any help would be greatly appreciated.

Update:

private static final int READ_REQUEST_CODE = 42;

in the code

  Button buttonLoadImage = (Button) findViewById(R.id.btnPictureSelect);
    buttonLoadImage.setOnClickListener(new View.OnClickListener() {
        @Override
        public void onClick(View arg0) {
            Intent imageIntent = new Intent(Intent.ACTION_OPEN_DOCUMENT);
            imageIntent.addCategory(Intent.CATEGORY_OPENABLE);
            imageIntent.setType("image/*");
            imageIntent.setAction(Intent.ACTION_GET_CONTENT);
            startActivityForResult(imageIntent , READ_REQUEST_CODE);
        }
    });

} 

    @Override
    protected void onActivityResult(int requestCode, int resultCode, Intent data) {
        super.onActivityResult(requestCode, resultCode, data);

        if (requestCode == READ_REQUEST_CODE && resultCode == Activity.RESULT_OK) {

            Uri uri = null;
            if (data != null) {
                uri = data.getData();
                Log.i(TAG, "Uri: " + uri.toString());
                showImage(uri);
            }
        }
    }

    private void showImage(Uri uri) {
        // TODO Auto-generated method stub
          ImageView imageView = (ImageView) findViewById(R.id.profilePicturePreview);
        imageView.setImageUri(Uri.parse(new File("path_to_your_image".toString()));
    }

error:

The method parse(String) in the type Uri is not applicable for the arguments (File)

in line

imageView.setImageUri(Uri.parse(new File("path_to_your_image".toString()));

Update 2:

private void showImage(Uri uri) {
    // TODO Auto-generated method stub
      ImageView imageView = (ImageView) findViewById(R.id.profilePicturePreview);
       imageView.setImageUri(Uri.fromFile(new File("/sdcard/myimage.jpg")));

error:

The method setImageUri(Uri) is undefined for the type ImageView

Answer 1

It would be better to use Intent to search the image type files available in your device.

Intent imageIntent = new Intent(Intent.ACTION_OPEN_DOCUMENT);
imageIntent.addCategory(Intent.CATEGORY_OPENABLE);
imageIntent.setType("image/*");
imageIntent.setAction(Intent.ACTION_GET_CONTENT);
startActivityForResult(imageIntent , READ_REQUEST_CODE); // set READ_REQUEST_CODE to 42 in your class

Now, process your results in the onActivityResult() method.

protected void onActivityResult(int requestCode, int resultCode, Intent data) {

if (requestCode == READ_REQUEST_CODE && resultCode == Activity.RESULT_OK) {

        Uri uri = null;
        if (data != null) {
            uri = data.getData();
            Log.i(TAG, "Uri: " + uri.toString());
            showImage(uri);
        }
}
