android - Google Photos vs Stock Gallery - Intent Picker

In my app, I allow the user to pick a profile image from their gallery, like so:

enter image description here

When You click the first option, on my Android 5.0 device, I get this:

enter image description here

If I use the normal Gallery app that is based off the AOSP project, everything works fine and dandy. However, the Photo's app appears to use a different intent.

Here is how I handle code for the normal gallery:

Intent photoPickerIntent = new Intent(
                    Intent.ACTION_PICK,
                    android.provider.MediaStore.Images.Media.EXTERNAL_CONTENT_URI);
            photoPickerIntent.setType("image/*");
            photoPickerIntent.putExtra("crop", "true");
            photoPickerIntent.putExtra("outputX", 300);
            photoPickerIntent.putExtra("outputY", 300);
            photoPickerIntent.putExtra("aspectX", 1);
            photoPickerIntent.putExtra("aspectY", 1);
            photoPickerIntent.putExtra("scale", true);
            photoPickerIntent.putExtra(MediaStore.EXTRA_OUTPUT, getTempUri());
            photoPickerIntent.putExtra("outputFormat",
                    Bitmap.CompressFormat.JPEG.toString());
            startActivityForResult(photoPickerIntent, RESULT_LOAD_IMAGE);

And then the intent result handler:

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

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

        if (data != null) {

            tempFile = getTempFile();

            filePath = Environment.getExternalStorageDirectory() + "/"
                    + "temporary_holder.jpg";
            Log.d("LOAD REQUEST filePath", filePath);

            Bitmap selectedImage = BitmapFactory.decodeFile(filePath);
            iPP.setImageBitmap(selectedImage);

        }

        imagePath = filePath;
        new UploadImage().execute();
    }
}

Some of the helper functions from above:

   private static Uri getTempUri() {
        return Uri.fromFile(getTempFile());
    }

    private static File getTempFile() {

        if (Environment.getExternalStorageState().equals(
                Environment.MEDIA_MOUNTED)) {

            File file = new File(Environment.getExternalStorageDirectory(),
                    "temporary_holder.jpg");
            try {
                file.createNewFile();
            } catch (IOException e) {
                e.printStackTrace();
            }

            return file;
        }
        return null;
    }

Some of that is probably not needed to show but I included it all in case it is interfering.

When I use Google Photos to pick a photo, my ImageView is blank (instead of filling with selected pick). The image is not selected and I can't go to the manual cropping view like I have it set with the Gallery. So basically, nothing happens.


NEW CODE IN RESPONSE TO ANSWER

        photoPickerIntent = new Intent(Intent.ACTION_GET_CONTENT);
        photoPickerIntent.setType("image/*");
        photoPickerIntent.putExtra("crop", "true");
        photoPickerIntent.putExtra("outputX", 300);
        photoPickerIntent.putExtra("outputY", 300);
        photoPickerIntent.putExtra("aspectX", 1);
        photoPickerIntent.putExtra("aspectY", 1);
        photoPickerIntent.putExtra("scale", true);
        photoPickerIntent.putExtra(MediaStore.EXTRA_OUTPUT, getTempUri());
        photoPickerIntent.putExtra("outputFormat",
                Bitmap.CompressFormat.JPEG.toString());
        startActivityForResult(photoPickerIntent, RESULT_LOAD_IMAGE);



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



    if (resultCode == Activity.RESULT_OK) {

        if (data != null) {

            Log.i("data", data.toString());

            switch (requestCode) {

                case RESULT_LOAD_IMAGE:

                    Log.i("RESULT_LOAD_IMAGE", "MARK");
                    // Received an image from the picker, now send an Intent for cropping
                    final String CROP_ACTION = "com.android.camera.action.CROP";
                    Intent photoCropIntent = new Intent(CROP_ACTION);
                    photoCropIntent.putExtra("crop", "true");
                    photoCropIntent.putExtra("aspectX", 1);
                    photoCropIntent.putExtra("aspectY", 1);
                    photoCropIntent.putExtra("outputX", 300);
                    photoCropIntent.putExtra("outputY", 300);
                    photoCropIntent.putExtra(MediaStore.EXTRA_OUTPUT, getTempUri());
                    photoCropIntent.putExtra("outputFormat",
                            Bitmap.CompressFormat.JPEG.toString());
                    photoCropIntent.setData(data.getData());

                    startActivityForResult(photoPickerIntent, RESULT_CROP_IMAGE);

                    break;

                case RESULT_CROP_IMAGE:

                    Log.i("RESULT_CROP_IMAGE", "MARK");

                    tempFile = getTempFile();
                    imagePath = Environment.getExternalStorageDirectory() + "/"   + "temporary_holder.jpg";
                    Log.i("imagePath", imagePath);

                    Uri selectedImageURI = data.getData();
                    InputStream image_stream;
                    try {
                        image_stream = getActivity().getContentResolver().openInputStream(selectedImageURI);
                        Bitmap bitmap = BitmapFactory.decodeStream(image_stream);
                        iPP.setImageBitmap(bitmap);
                    } catch (FileNotFoundException e) {
                        e.printStackTrace();
                    }
                    new UploadImage().execute();

                    break;

                default:
                    // Handle default case
            }
        }

    }

}

The above code isn't working either. I tried to make it resemble the answer below. What happens is:

I click "Choose from Gallery". And it does not give me a choice anymore, now it opens directly from the stock Gallery (that is not a big deal). I click on the image, and it ... appears to start the same intent over again -- it brings back the gallery wanting me to pick another image: instead of the Cropping Activity. Then after the second time, it will set my ImageView with the selected file.

Solution

First, update the photoPickerIntent to use ACTION_GET_CONTENT, and remove the extras related to cropping, since cropping will be handled by another Intent later:

        Intent photoPickerIntent = new Intent(Intent.ACTION_GET_CONTENT);
        photoPickerIntent.setType("image/*");
        // Do not include the extras related to cropping here;
        // this Intent is for selecting the image only.
        startActivityForResult(photoPickerIntent, RESULT_LOAD_IMAGE);

Then, onActivityResult() will have to handle two results: RESULT_LOAD_IMAGE will send another intent for the crop, and RESULT_CROP_IMAGE will continue processing as you did before:

    public void onActivityResult(int requestCode, int resultCode, Intent data) {
        if (resultCode == Activity.RESULT_OK) {
            if (data != null) {
                switch (requestCode) {
                case RESULT_LOAD_IMAGE:
                    // Received an image from the picker, now send an Intent for cropping
                    final String CROP_ACTION = "com.android.camera.action.CROP";
                    Intent photoCropIntent = new Intent(CROP_ACTION);
                    photoCropIntent.setData(data.getData());

                    // TODO: first get this running without extras, then test each one here
                    startActivityForResult(photoCropIntent, RESULT_CROP_IMAGE);
                    break;
                case RESULT_CROP_IMAGE:
                    // Received the cropped image, continue processing.  Note that this 
                    // is just copied and pasted from your question and may have 
                    // omissions.
                    tempFile = getTempFile();

                    filePath = Environment.getExternalStorageDirectory() + "/"
                            + "temporary_holder.jpg";
                    Log.d("LOAD REQUEST filePath", filePath);

                    Bitmap selectedImage = BitmapFactory.decodeFile(filePath);
                    iPP.setImageBitmap(selectedImage);

                    imagePath = filePath;
                    new UploadImage().execute();
                    break;
                default:
                    // Handle default case
                }
            }
        }

Note that although I've tested parts of this code, I haven't tested this entire block of code at runtime. If it doesn't work right out-of-the-box, though, it should be pretty close. Please comment if you have any questions or issues, and I'll update my answer accordingly.

Background

On an Android 5.0.1 (API 21) device with both AOSP Gallery2 (com.android.gallery3d) and Photos installed, I ran your Intent. I was prompted to choose between Gallery or Photos.

When I chose Photos, a picker was presented, and I picked an image. I was immediately returned to my Activity, with no cropping options.

When I chose Gallery, a picker was presented, and I picked an image. I was then prompted to choose an app for cropping. Both Photos and Gallery were presented as options for cropping.

Here's the interesting log output when choosing Gallery:

// Send the Intent

First, note W/GalleryActivity﹕ action PICK is not supported. I'm not sure why it works, but according to Dianne Hackborn, "...you should consider ACTION_PICK deprecated. The modern action is ACTION_GET_CONTENT which is much better supported..." I've addressed this in my solution above.

The good news is, however, it seems that after picking an image, .putExtra("crop", "true"); causes Gallery to send another Intent for cropping. And the log clearly shows the action and data to use.

I tested this cropping intent, and I was prompted to choose an app for cropping, just like before. And again, both Photos and Gallery were presented as options, and they both brought up cropping interfaces.

It seems that although Photos supports cropping by Intent, it just ignores the extras relating to cropping in ACTION_PICK, whereas Gallery responds by sending another Intent after picking an image. Regardless, having the details of a working cropping Intent leads to the solution above.
