Build Bigger Android Apps, Faster: Why Git LFS Is a Game-Changer for Large Assets

 


Tame large files and streamline your development workflow with Git Large File Storage (LFS)

If you're an Android developer building feature-rich apps with stunning graphics, on-device machine learning, or immersive media — chances are you've bumped into Git’s limitations.

From high-res images and videos to .tflite models and APKs, large files can seriously slow down your Git repo, mess with version control, and frustrate your team. That’s where Git Large File Storage (LFS) comes in.

In this post, you'll learn how Git LFS helps Android developers manage large assets more efficiently, avoid Git pitfalls, and deliver faster, cleaner projects.

Why Android Projects Need Git LFS

Modern Android apps aren’t just about code — they’re rich experiences powered by assets:

  • Images and animations for splash screens, UI elements, and AR

  • Audio and video files for e-learning, podcasts, or games

  • Machine learning models for features like face detection or text translation

  • Database files and binary data

  • APKs or AABs for QA or internal testing

Trying to version these directly in Git leads to bloated repos, massive clone times, and version control nightmares. Git wasn't designed for this — but Git LFS is.

What Is Git LFS (and How Does It Work)?

Git LFS replaces large files with lightweight text pointers inside your Git repo. The actual content is stored externally, and fetched only when needed.

Here’s how it changes the game:

  • Instead of uploading a 90MB .tflite model directly to your Git history...

  • You store a tiny reference to it in the repo, while Git LFS keeps the actual file in a separate storage system.

This keeps your Git repo fast, lean, and versionable — even when dealing with big binary files.

Real-World Use Cases in Android

1. Machine Learning On-Device

Use Case: An Android camera app uses an 85MB object detection .tflite model.

With Git LFS, the model is version-controlled and shared among team members without bloating the repository. Developers only download it when they actually need to.

2. Game or Media-Rich Apps

Use Case: A mobile puzzle game includes animations, soundtracks, and high-resolution assets.

Storing these directly in Git slows down everything — from clones to commits. Git LFS separates the heavy lifting so only relevant assets are fetched when needed.

3. CI/CD Pipelines with APKs

Use Case: QA needs access to nightly APK builds, which are stored in GitHub.

Instead of bloating the repo with binaries, Git LFS lets you version APKs externally but still access them in your CI pipeline and commit history.

Benefits of Git LFS for Android Devs

  • Faster Clones: Don’t download 500MB of assets just to read the code.

  • Smaller Repo Sizes: Keep your version history clean and manageable.

  • Cleaner Git Diffs: No massive binary diffs cluttering your history.

  • Better CI/CD: Pull in large files as needed during builds.

  • Improved Collaboration: Teammates don’t break assets when working across branches.

Setting Up Git LFS in Your Android Project

Step 1: Install Git LFS

# macOS
brew install git-lfs

# Ubuntu/Debian
sudo apt install git-lfs

# Windows
choco install git-lfs

# Initialize Git LFS
git lfs install

Step 2: Track Large Files

Choose the file types you want LFS to manage:

git lfs track "*.tflite"
git lfs track "*.png"
git lfs track "*.mp4"
git lfs track "*.apk"

This updates your .gitattributes file. Be sure to commit it:

git add .gitattributes
git commit -m "Track large assets with Git LFS"

Step 3: Use Git as Usual

git add app/src/main/assets/model.tflite
git commit -m "Add ML model"
git push origin main

Git LFS takes over in the background, storing the actual file externally and leaving a pointer in the repo.

CI/CD Integration (Example: GitHub Actions)

Make sure your pipeline pulls LFS files:

- name: Checkout Repository
  uses: actions/checkout@v3
  with:
    lfs: true

Now your builds can access models, images, and binaries seamlessly.

Tips and Gotchas

  • Be Specific: Don’t blindly track all *.png files — you might catch assets that don’t need LFS.

  • Everyone Needs Git LFS: Team members must install it to avoid broken pointers.

  • Mind Your Limits: GitHub's free tier includes 1GB of LFS storage and 1GB of bandwidth/month.

Want more? You can upgrade your LFS quota or host your own LFS server.

Final Thoughts

As Android apps become more advanced — blending beautiful visuals with AI, AR, and immersive media — managing large assets is no longer optional. Git LFS gives you the structure and speed you need without compromising on version control.

Whether you're shipping a media-rich app or a machine learning-powered experience, Git LFS lets you build bigger, better Android apps — faster.

Kotlin Some important unsorted interview questions and answers

Senior Answer Sometimes it is necessary for business logic to create a wrapper around some type. However, it introduces runtime overhead due to additional heap allocations. Moreover, if the wrapped type is primitive, the performance hit is terrible, because primitive types are usually heavily optimized by the runtime. Inline classes  provide us with a way to wrap a type, thus adding functionality and creating a new type by itself. As opposed to regular (non-inlined) wrappers, they will benefit from improved performance. This happens because the data is inlined into its usages, and object instantiation is skipped in the resulting compiled code. inline class Name ( val s : String ) { val length : Int get ( ) = s . length fun greet ( ) { println ( "Hello, $s " ) } } fun ma...

Null safety based Kotlin interview questions and answers

Nullable Non Nullable Types What’s Null Safety and Nullable Types in Kotlin? What is the Elvis Operator? Kotlin puts a lot of weight behind null safety which is an approach to prevent the dreaded Null Pointer Exceptions by using nullable types which are like  String? ,  Int? ,  Float?  etc. These act as a wrapper type and can hold null values. A nullable value cannot be added to another nullable or basic type of value. To retrieve the basic types we need to use safe calls that unwrap the Nullable Types. If on unwrapping, the value is null we can choose to ignore or use a default value instead. The Elvis Operator is used to safely unwrap the value from the Nullable. It’s represented as  ?:  over the nullable type. The value on the right hand side would be used if the nullable type holds a null. var str: String ? = "JournalDev.com" var newStr = str?: "Default Value" str = null newStr = str?: "Default Value" How is  !! different from ?. in unwrappi...
