About the app:
The Wikimedia Commons Android app allows users to upload pictures from their Android phone/tablet to Wikimedia Commons. Wikimedia Commons accepts only freely licensed media files (that are not subject to any copyright). Users can upload images and then add various tags specific to them such as category, title, description, and license.

About the project:
The goal of this project is to enhance the already working Wikimedia Commons App by implementing an option to browse/search the Wikimedia Commons Repository.

Why this feature is needed?

  • More and more users are asking (as evident by Play Store feedback)to be able to also browse existing Commons images via the app
  • Quality of uploads will increase by letting users see other people's work

What can be implemented ?

  • Image Search on Wikimedia Commons using a text
  • Restrict the search results to images
  • Category Search
  • Previous Search queries of images and categories (Recent Search history)
  • Shows the sub-categories and the images present in that category
  • Allow users to skip login and browse and search in the app

How it can be implemented?

  • Explore Mediawiki APIs to search images using titles, search categories.(Probably using Mediawiki Search API)
  • Implement search activity which will contain 2 tabs
  • tab 1 for showing image list (if possible reusing featured images fragment)
  • tab 2 for showing category list
  • Implement async call requests to request search pictures, search categories dynamically on page scroll
  • Develop feature for displaying search results in search activity
  • Saving the clicked category/images in the local database
  • Showing in the recently searched list (both categories and images) if a search query is empty
  • Implement the category activity which will contain 2 tabs
  • tab 1 for showing sub-category list
  • tab 2 for showing images inside the category (if possible reusing featured images fragment)
  • Improving category activity by showing best images (images inside subcategory) using FastCCI
  • Add an option to skip login in Login Page which redirects to Featured Image Activity

I’ve been working on this feature for some time now. I had made a small prototype for the same.

  • Description
  • Added a Separate activity for search in which an edit text is present
  • Implemented a viewpager along with a tab layout in the activity
  • Added Browse Image fragment, Browse Category Fragment in the item of the viewpager
  • Now if a text is changed in the activity I call update list method in both the fragments with search query as a parameter
  • Method update list updates the list by fetching details from Wikimedia API: Search
  • For updating the list in recycler view I had added AdapterFactory, Renderer similar to other modules.

About Me

Personal background

I am a third-year B.Tech. undergraduate at Indian Institute of Technology (ISM), Dhanbad . I am pursuing Electronics and Communication Engineering as my Major. I have a keen interest in Android App development( I have been doing Android App Development from last 2 years). I use git and Github every day and I am well acquainted with how to use them for version control.

How did I hear about this program?

Heard about GSoC in a campus meetup. I am an open source enthusiast from past 1 year, I've always wanted to take part in Google Summer of Code.

Time during Summers

I have no other commitments this summer. So I'll be able to give 40 hours or more per week. My summer break starts on 30th April so I can start working full time from that day on. I'll not be taking any vacations. My classes start around 20th July but I will be able to commit enough time to the project as there are no exams during the period

Eligible for Google Summer of Code and Outreachy ?

I am applying only for GSoC as I am not eligible for Outreachy program. I am applying under Wikimedia Commons Android only.

What excites me about this project
I had developed a lot of apps during my college days, but I always wanted to develop apps that really help people. I loved the goal of Wikimedia Foundation "Global movement whose mission is to bring free educational content to the world".
I would be really great for me to apply my skills and contribute to such an organization.

Past Experience

I’ve been doing Android development since my first year. My first project was a Home Automation app to control LED lights using our mobile phone(Raspberry Pi behaving as a server)that I built in a hackathon. After that, I had started making apps for my learning purpose. Apart from the prototypes, I had also developed 2 apps that are on Google Play.

I had developed this app for our departmental fest of electronics engineering (Spectrum). It has features like login, OTP verification using the phone number, Show list of events day wise, register for events, send notification for events.

Brand Store:
It is an app where users can get offers from nearby shops of different categories across their city. Shops can also register them and show their offers to the users of the app. Although the startup is closed now. but the app is still on google play.

Apart from this, I also have received the Google India Challenge scholarship for Android Developer nanodegree this year.

Contributions to Wikimedia Commons App

It has been an enriching experience contributing to the app and I look forward to continuing contributing to it. For all I have learned so far is that your contributions are not just the number of Pull Requests that you’ve got merged. But contributions can be in various forms like:

  • Creating New Issues
  • Finding Bugs
  • Helping New Contributors
  • Communicating with Moderators and helping them
Pull Requests:
  • Merged Pull Requests: (8/12)
  • Closed Pull Requests:
  • Closed Issues: (10/16)

Hi @Ujjwalagrawal17 ,

Thanks for putting this proposal up. I am guessing that tasks and deliverables are still being worked on? That's totally fine, but I would recommend putting the deliverables next to the tasks in the table (in a 3rd column), that will make it easier for us to view them.

Ujjwalagrawal17 renamed this task from GSoC Proposal : Feedback Sharing Module in Commons App to [Wikimedia Commons app] Allow users to browse Commons from app.
Ujjwalagrawal17 raised the priority of this task from Normal to Needs Triage.

Is the proposal to be modified in any other way?
Adding more detail for something, Removing some detail, Changing the order of writing things, Anything wrongly written, Any comments on the readability of the proposal

@Nes @Nicolas_Raoul Can you review it once, please :)

Is there any difference between "Improvements based on the feedback received from mentors, other community members, Testing, Bug fixes, Writing documentation. Release app in Google play (at least in alpha)" and "Phase I evaluation"?
Is there a reason why Phase II is in the opposite order?

Minor notes:
to browse/search the Wikimedia Commons using the app -> to browse/search the Wikimedia Commons repository using the app (sounds more natural)
Image Search on Wikimedia Commons using a title. -> Image Search on Wikimedia Commons using text. (search will be done using not only "title" but also other metadata such as "description")
async calls requests -> async call requests
category/ images -> category/images
list(both -> list (both (space before parenthesis, in other places too)
Learning JavaRx, Getting Familiar with -> learning JavaRx, getting familiar with (no need for uppercase)
sanckbar -> snackbar

At first I misunderstood "Search history of images" as "Search in the successive versions of an image", actually it means being able to see your previous search queries, right?

@Nicolas_Raoul Thanks for the review I will update the proposal accordingly. I will update the timeline for Phase1 and Phase 2 evaluation and show it again. Actually, phase 1 and 2 are similar not in the opposite order. I will make it more clear and understandable.

@Nicolas_Raoul I had updated the proposal. Any other suggestions.

After the project, Image, Category Search on Wikimedia Commons is successfully included in the Wikimedia Commons App. Users can open the search page from Explore Activity of the app. A page for category details page which contains the list of images, subcategories, parent categories were added in the app and linked with various parts of the app. Users can now skip login if they don’t want to create an account and browse commons from the app.

Here is the link to Project Presentation that I made in the final week.

Successfully merged Pull Requests for the Project

This is the first time I have sent 50+ merged PRs for any open source project and I am very happy about it. Here is the link that contains information about the merged PRs.

I have also added other details about the project in past projects section in

Can we close this now? @srishakatux
