Binary Runner (Android)

Single-screen Flutter app to run arbitrary binaries on an Android device.

Android 16 (Baklava) Release

• Target: Android 16 / API 36 (Baklava)
• Emulator AVD: baklavaApi36 (Google APIs, arm64-v8a)
• Built artifact: build/app/outputs/flutter-apk/app-release.apk

Screenshots

App Icon

This project includes a simple adaptive launcher icon.

• Background color: #1E2A44
• Foreground: vector triangle mark

Android resources added:

• android/app/src/main/res/values/colors.xml
• android/app/src/main/res/drawable/ic_launcher_foreground.xml
• android/app/src/main/res/mipmap-anydpi-v26/ic_launcher.xml

UI

• path: directory that contains the binary (e.g. /data/local/tmp).
• binary_name: the executable filename (e.g. mytool).
• • button: add argument rows. Each row has optional arg_name and arg_value.
  • If arg_name provided, app sends --arg_name then value (if any).
  • If only value is provided, it's passed positionally.
• Run via su (root): toggle to execute with su -c.
• Run: executes <path>/<binary_name> with your args and shows stdout/stderr/exit code.

Android specifics

• When "Run via su" is ON, the app runs su -c "<cmd>". This requires a rooted device.
• Without su, the process must be executable and accessible by the app sandbox.

Build and run

Use Flutter tooling as usual. Example:

flutter run -d <your_android_device_id>

Notes

• Make sure your binary is built for the device architecture and has execute permissions (e.g. chmod +x /data/local/tmp/mytool).
• If execution fails, check stderr in the app for permission/SELinux denials.
