Auto Tapper

An Android app that automates tapping on TikTok using the Accessibility Service API. A floating overlay button lets you start/stop tapping without leaving TikTok, and the overlay displays a live tap count and estimated likes in real time.

Requirements

• Android 7.0+ (API 24)
• TikTok installed (com.zhiliaoapp.musically or TikTok Lite)
• Accessibility Service permission
• Draw Over Other Apps permission

Setup

1. Build and install the app
2. Open Auto Tapper and tap Enable Accessibility Service — this opens Android Settings where you enable the service
3. Tap Grant Overlay Permission and allow the app to draw over others
4. Return to Auto Tapper and configure your settings

Settings

Tap Speed (1–9 taps/sec)

Controls how many gestures are dispatched per second. 7 taps/sec is the recommended setting — it keeps Android's gesture dispatcher from backing up without meaningfully reducing throughput.

Taps per Trigger (1× / 2× / 3×)

Number of strokes bundled into each gesture dispatch. Each extra stroke is offset by 60ms so they don't overlap.

• 1× — default, best reliability
• 2× / 3× — useful only if session logs show a high cancellation rate at 1×

Recommended combination: 7 taps/sec + 1×

Usage

1. Open TikTok and navigate to a video
2. The floating overlay appears in the top-right corner
3. Tap ▶ to start — the button turns green and counters update live
4. Tap ■ to stop — the button turns red and a session summary is logged
5. Tapping stops automatically when you leave TikTok

Architecture

MainActivity.kt       — Configuration UI (speed, multiplier, permissions)
AutoTapperService.kt  — AccessibilityService: floating overlay, gesture loop, foreground guard
LikesCalculator.kt    — Estimates likes from tap counts using measured efficiency constants

Efficiency constants (measured from real sessions):

• App efficiency: 96.78% (gesture completion rate)
• Like registration rate: 97.8% (completed taps that register as likes)
• Combined: ~94.65%

Build

./gradlew assembleDebug       # Build debug APK
./gradlew installDebug        # Install on connected device
./gradlew assembleRelease     # Build release APK
./gradlew clean               # Clean build artifacts

Debugging

Session stats are logged under the TapperService tag on stop:

Session summary — attempts: 420 | completed: 408 | cancelled: 12 | foreground losses: 0 | success rate: 97%

If success rate drops below 85%, reduce tap speed by 1–2 steps.
