# Android Test App
|
|
|
|
A demonstration Android application designed for testing device stress scenarios and app behavior under various conditions. This app provides three main testing features: battery draining, intentional bad behavior (crashes/ANRs), and download scheduling.
|
|
|
|
## Features
|
|
|
|
### 1. Battery Drainer
|
|
Tests battery consumption through intensive use of device hardware components:
|
|
|
|
- **CPU Operations**: Mathematical calculations and intensive loops
|
|
- **Display**: Maximum brightness with screen always on
|
|
- **Flashlight**: Continuous or strobe patterns
|
|
- **GPS**: High-accuracy location updates
|
|
- **Bluetooth**: Continuous BLE scanning
|
|
- **WiFi**: Network scanning
|
|
- **Sensors**: Accelerometer, gyroscope, magnetometer continuous reading
|
|
- **Camera**: Preview without recording
|
|
- **Audio**: Silent playback to keep audio subsystem active
|
|
- **Vibration**: Continuous patterns
|
|
|
|
**Presets Available:**
|
|
- Maximum Drain (all features enabled)
|
|
- CPU & GPU Focus
|
|
- Radio Focus (GPS, BLE, WiFi)
|
|
- Sensor Focus
|
|
|
|
### 2. Bad Behavior Simulator
|
|
Intentionally triggers app crashes and ANRs for testing crash reporting and monitoring systems:
|
|
|
|
**Crash Types:**
|
|
- Division by zero
|
|
- Null pointer exception
|
|
- Out of memory error
|
|
- Stack overflow
|
|
- Array index out of bounds
|
|
|
|
**ANR Triggers:**
|
|
- UI thread blocking
|
|
- Broadcast receiver timeout
|
|
- Service timeout
|
|
|
|
**Configuration Options:**
|
|
- Manual or automatic triggering
|
|
- Random intervals
|
|
- Auto-restart after crash
|
|
|
|
### 3. Download Manager
|
|
Schedules and executes file downloads with configurable parameters:
|
|
|
|
- Custom or preset download URLs
|
|
- File size options (1MB, 10MB, 100MB, custom)
|
|
- Scheduling: one-time, repeating, or specific times
|
|
- Network preferences (WiFi only, cellular only, any)
|
|
- Concurrent download support (1-10 simultaneous)
|
|
- Background download capability
|
|
- Download history tracking
|
|
|
|
## Requirements
|
|
|
|
- Android 12+ (API level 32)
|
|
- Target SDK: Android 15 (API level 35)
|
|
|
|
## Permissions
|
|
|
|
The app requires the following permissions (automatically requested on launch):
|
|
- Camera
|
|
- Location (Fine and Coarse)
|
|
- Bluetooth (Scan and Connect)
|
|
- Internet and Network State
|
|
- WiFi State
|
|
- Vibrate
|
|
- Wake Lock
|
|
- Foreground Service
|
|
- External Storage (for downloads)
|
|
- High Sampling Rate Sensors
|
|
|
|
## Building the Project
|
|
|
|
### Prerequisites
|
|
- Android Studio (latest stable version recommended)
|
|
- JDK 17 or higher

## Architecture
|
|
|
|
- **MainActivity**: Launch screen with navigation to three feature activities
|
|
- **BatteryDrainActivity**: Configure and run battery drain tests
|
|
- **BadBehaviorActivity**: Configure and trigger crashes/ANRs
|
|
- **DownloaderActivity**: Configure and manage downloads
|
|
- **Background Services**: Handle battery drain and download operations
|
|

|
|
|
|
## Usage
|
|
|
|
1. Launch the app
|
|
2. Grant requested permissions
|
|
3. Select one of the three testing features from the main menu
|
|
4. Configure test parameters as needed
|
|
5. Start the test and monitor results
|
|
|
|
## Development
|
|
|
|
This project uses:
|
|
- Kotlin as the primary language
|
|
- Gradle with Kotlin DSL for build configuration
|
|
- AndroidX libraries
|
|
- Version catalog for dependency management
|
|
|
|
## Warning
|
|
|
|
⚠️ **This app is designed for testing purposes only!** It intentionally:
|
|
- Drains battery rapidly
|
|
- Causes app crashes and system stress
|
|
- Consumes network bandwidth
|
|
- Uses device resources intensively
|
|
|
|
Use responsibly and only on test devices or when specifically needed for development/testing purposes.
