What it is

Dexter is an Android library (Java, 112KB codebase) that abstracts the complexity of Android 6.0+ runtime permissions into a fluent, callback-based API. Instead of writing permission-checking boilerplate in Activities, developers call Dexter.withContext(activity).withPermission(Manifest.permission.CAMERA).withListener(listener).check() and handle grants/denials in listener callbacks. It handles the entire flow: checking grant status, showing system dialogs, managing rationale screens, and invoking permission callbacks on the correct thread. Single-module library structure: dexter/src/main/java/com/karumi/dexter/ contains the core engine (Dexter.java entry point, DexterActivity.java for…

Start here

Open these first:

• dexter/src/main/java/com/karumi/dexter/Dexter.java — Main entry point and public API facade that developers use to request permissions; defines the core DexterBuilder pattern.
• dexter/src/main/java/com/karumi/dexter/DexterInstance.java — Core state machine that manages the permission request lifecycle and coordinates with the permission service.
• dexter/src/main/java/com/karumi/dexter/AndroidPermissionService.java — Low-level abstraction over Android's runtime permission system; bridges native Android APIs to the Dexter request model.
• dexter/src/main/java/com/karumi/dexter/DexterActivity.java — Invisible activity used to capture Android's permission request results and deliver callbacks to listeners.
• dexter/src/main/java/com/karumi/dexter/listener/multi/MultiplePermissionsListener.java — Core listener interface for multi-permission requests; all permission result handling flows through this contract.

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.

Clone the repo, sync Gradle dependencies, and run the sample app:

git clone https://github.com/Karumi/Dexter.git
cd Dexter
./gradlew build
./gradlew installDebug  # or open in Android Studio and run

Daily commands:

In Android Studio: File → Open → select Dexter root folder → Gradle sync → Run (or ./gradlew installDebug from CLI). No dev server; this is a library meant to be included as a dependency.

Key cautions & unknowns

• Stale — last commit 5y ago
• No test suite: file list shows zero test files; all testing must be manual on Android devices. Thread marshaling: callbacks are forcibly executed on MainThread via MainThread.java—custom listeners that call…
• Published-advisory coverage was unavailable for the captured dependencies.
• Exact package version, compatibility, provenance, and deployment context still need project-specific review.
