# MobileDev-Bench
**MobileDev-Bench** is a benchmark of **407 verified real-world issue-resolution tasks** collected from 19 production mobile app repositories spanning Android Native (Java/Kotlin), React Native (TypeScript), and Flutter (Dart). It evaluates the ability of large language models to resolve authentic developer-reported issues in mobile applications through execution-based validation.
>**GitHub:** [mobiledev-bench](https://github.com/MobileDev-Bench/mobiledev-bench) *(evaluation harness, scripts, docker images)*

## 📊 Key Facts
| | |
|---|---|
| **Tasks** | 407 verified instances |
| **Repositories** | 19 production mobile apps |
| **Frameworks** | Android Native · React Native · Flutter |
| **Languages** | Kotlin · Java · TypeScript · Dart |
| **Difficulty tiers** | Easy (138) · Medium (139) · Hard (130) |
| **Avg. files changed** | 12.9 |
| **Avg. lines changed** | 334.6 |
| **Multi-artifact fixes** | 41% of instances |
| **Human verified** | ✅ All instances manually verified |
<!-- ---
## Leaderboard
Resolution rate = resolved / evaluated instances (higher is better). Both **Agentless** and **Oracle** settings are reported; the Oracle setting provides ground-truth file context to the model.
| Model | Agentless (%) | Oracle (%) |
|---|---|---|
| Claude Sonnet 4.5 | **4.15** | **6.07** |
| Qwen3 Coder | 4.28 | 2.52 |
| GPT 5.2 | 3.90 | 5.19 |
| Gemini 2.5 Flash | 4.16 | 1.94 |
Resolution rates drop sharply for multi-file tasks. Single-file instances resolve at ~13–16% (Agentless); rates approach 0% for tasks touching 6+ files. -->

## 📖 Dataset Description
### Motivation
Existing issue-resolution benchmarks (SWE-bench and its extensions) target general-purpose Python/JavaScript libraries. Mobile app development imposes distinct engineering constraints: platform-defined lifecycles, framework-specific build systems (Gradle, pub, npm), and correctness that depends on coordinated changes across heterogeneous artifacts — source files, manifests, resource definitions, and configuration metadata. MobileDev-Bench is the first benchmark to evaluate LLMs on these challenges at scale.
### Construction
Each instance was derived from a merged GitHub pull request that resolves at least one linked issue. The pipeline:
1. **Crawl** — Pull requests and linked issues collected from 19 repositories (≥400 GitHub stars each).
2. **Filter** — Instances with no linked issue, no test changes, or non-compilable base commits are excluded.
3. **Verify** — Test execution under three configurations (base commit, test patch only, full fix) confirms that the fix produces a genuine Fail-to-Pass or None-to-Pass transition.
4. **Annotate** — Human annotators assign difficulty tiers (Easy / Medium / Hard) and label artifact types involved in each fix.
### Splits
| Split | Instances | Description |
|---|---|---|
| `test` | 407 | Verified benchmark instances with full evaluation metadata (`fix_patch`, `test_patch`, `test_command`, test results) |
