[android] Select multiple images from android gallery

Initialize instance:

private String imagePath;
private List<String> imagePathList;

In onActivityResult You have to write this, If-else 2 block. One for single image and another for multiple image.

if (requestCode == GALLERY_CODE && resultCode == RESULT_OK  && data != null){

    imagePathList = new ArrayList<>();

    if(data.getClipData() != null){

        int count = data.getClipData().getItemCount();
        for (int i=0; i<count; i++){

            Uri imageUri = data.getClipData().getItemAt(i).getUri();
            getImageFilePath(imageUri);
        }
    }
    else if(data.getData() != null){

        Uri imgUri = data.getData();
        getImageFilePath(imgUri);
    }
}

Most important part, Get Image Path from uri:

public void getImageFilePath(Uri uri) {

    File file = new File(uri.getPath());
    String[] filePath = file.getPath().split(":");
    String image_id = filePath[filePath.length - 1];

    Cursor cursor = getContentResolver().query(android.provider.MediaStore.Images.Media.EXTERNAL_CONTENT_URI, null, MediaStore.Images.Media._ID + " = ? ", new String[]{image_id}, null);
    if (cursor!=null) {
        cursor.moveToFirst();
        imagePath = cursor.getString(cursor.getColumnIndex(MediaStore.Images.Media.DATA));
        imagePathList.add(imagePath);
        cursor.close();
    }
}

Hope this can help you.
