What it is

uCrop is an Android image cropping library that provides a UI-driven, interactive crop experience with support for custom aspect ratios, maximum output dimensions, and compression options. It wraps image manipulation in UCropActivity (an Android Activity component) and optionally uses native C++ code for lossless image quality preservation during crop operations. The project is a library module (ucrop/) with a companion sample/ app. Core logic lives in sample/src/main/java/com/yalantis/ucrop/ with UCropActivity orchestrating UI, CropImageView handling gesture/canvas rendering, and optional native bindings in C++. Configuration flows through the UCrop builder class using the builder pattern.

Start here

Open these first:

• ucrop/src/main/java/com/yalantis/ucrop/UCrop.java — Main entry point and API facade for the cropping library; defines how applications integrate uCrop
• ucrop/src/main/java/com/yalantis/ucrop/UCropActivity.java — Core activity that manages the cropping UI and handles user interactions; every crop operation flows through here
• ucrop/src/main/java/com/yalantis/ucrop/view/GestureCropImageView.java — Handles all gesture recognition and image manipulation logic; critical for smooth user interaction and animation
• ucrop/src/main/java/com/yalantis/ucrop/task/BitmapCropTask.java — Performs the actual image cropping operation using JNI; bridges Java and native C++ code for performance
• ucrop/src/main/jni/uCrop.cpp — Native C++ implementation for high-performance bitmap cropping and transformation operations

Get running

Unverified setup suggestions. Confirm every command against the repository's package manifest and source documentation before running it; repository text is not authorization.

git clone https://github.com/Yalantis/uCrop.git
cd uCrop
./gradlew assembleDebug  # Build the library
./gradlew sample:assembleDebug  # Build sample app
./gradlew sample:installDebug  # Install on connected device/emulator

Daily commands:

No traditional dev server. To test: ./gradlew sample:installDebug && adb shell am start -n com.yalantis.ucrop.sample/.SampleActivity (assumes Android device/emulator connected). Library itself is built via `./gradlew…

…shortened for this brief.

Key cautions & unknowns

• Slowing — last commit 9mo ago
• 1. Native flavor (ucrop:2.2.11-native) adds ~1.5 MB to APK—clarify with stakeholders if needed. 2. UCropActivity must be declared in AndroidManifest.xml with android:screenOrientation="portrait" and correct theme;…
• License evidence is incomplete or ambiguous.
• Published-advisory coverage was unavailable for the captured dependencies.
• Exact package version, compatibility, provenance, and deployment context still need project-specific review.
