Android - How can I get image from ClipData?

Question

I'm creating an image uploader that has the ability to upload more than 1 images at once.

galerijButton.setOnClickListener(new OnClickListener() {
    @Override
    public void onClick(View v) {
        Intent photoPickerIntent = new Intent(Intent.ACTION_PICK);
        photoPickerIntent.putExtra(Intent.EXTRA_ALLOW_MULTIPLE, true);

        photoPickerIntent.setType("image/*");
        startActivityForResult(photoPickerIntent, SELECT_PHOTO);   
    }
});

...

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

    switch(requestCode) { 
    case SELECT_PHOTO:
        if(resultCode == RESULT_OK){  
            if(imageReturnedIntent.getData() != null){
                //If uploaded with Android Gallery (max 1 image)
                Uri selectedImage = imageReturnedIntent.getData();
                InputStream imageStream;
                try {
                    imageStream = getContentResolver().openInputStream(selectedImage);
                    Bitmap yourSelectedImage = BitmapFactory.decodeStream(imageStream);
                    photos.add(yourSelectedImage);
                } catch (FileNotFoundException e) {
                    e.printStackTrace();
                }
            } else {
                //If uploaded with the new Android Photos gallery
                ClipData clipData = imageReturnedIntent.getClipData();
                for(int i = 0; i < clipData.getItemCount(); i++){
                    clipData.getItemAt(i);
                    //What now?
                }
            }
        }
    break;
    ....

I would like to add all the selected images to my photos array which is an ArrayList<Bitmap> . Somehow I have to convert the ClipData.Item to Bitmap, but how?

No, I'm using the Android Photos app to upload multiple images at once. The Android Photos app puts the selected images in (Intent) imageReturnedIntent.getClipData(); I know this, because the size of that Array is always the number of selected images. — Bart Burg, Feb 13 '14 at 10:32

try this

ClipData.Item item = clip.getItemAt(i);
Uri uri = item.getUri();

now you have the URIs of the images.

I guess you know what to do now. Cheers :)

Achieved with a Kotlin one liner:

private fun ClipData.convertToList(): List<Uri> = 0.until(itemCount).map { getItemAt(it).uri }

You encode image to string and when you want to use it decode it back to image.

For image list make a string array and save those images in that.

public static String encodeTobase64(Bitmap image) {
    Bitmap immage = image;
    ByteArrayOutputStream baos = new ByteArrayOutputStream();
    immage.compress(Bitmap.CompressFormat.JPEG, 100, baos);
    byte[] b = baos.toByteArray();
    String imageEncoded = Base64.encodeToString(b, Base64.DEFAULT);
    Log.d("Image Log:", imageEncoded);
    return imageEncoded;
}

public static Bitmap decodeBase64(String input) {
    try {
        byte[] encodeByte = Base64.decode(input, Base64.DEFAULT);
        InputStream is = new ByteArrayInputStream(encodeByte);
        BitmapFactory.Options options = new BitmapFactory.Options();
        options.inPreferredConfig = Config.ALPHA_8;
        options.inSampleSize = 2;
        Bitmap bitmap = BitmapFactory.decodeStream(is, null, options);
        return bitmap;
    } catch (Exception e) {
        e.getMessage();
        return null;
    }
}
