How to Write Cloud Phone Scripts? Code Guide & Function Libraries

Cloud Phone Script Development Guide

Many developers new to cloud phones ask: how do you actually write cloud phone scripts? The essence of cloud phone scripting is simulating human operations on a phone through APIs or automation tools. This article will take you from zero to understanding the core knowledge of ChangChang Cloud Phone script development.

1. Script Development Environment Setup

Before writing scripts, you need to prepare the following development environment:

2. Connecting to ChangChang Cloud Phone

The first step is establishing a connection with the cloud phone instance. ChangChang Cloud Phone provides both RESTful API and WebSocket connection methods:

from changchang_sdk import CloudPhoneClient

# Initialize client
client = CloudPhoneClient(
    api_key="your_api_key",
    api_secret="your_api_secret"
)

# Connect to cloud phone instance
phone = client.connect(
    instance_id="cp_12345678",
    mode="streaming"  # Streaming mode
)

print(f"Connected, device ID: {phone.device_id}")

3. Basic Operation Functions

The ChangChang Cloud Phone SDK wraps common operation functions. Here's the core API overview:

4. Practical Example: Auto Sign-in Script

Here's a complete auto sign-in script example covering connection, operation, and screenshot verification:

from changchang_sdk import CloudPhoneClient
import time

def auto_signin(instance_id, api_key, api_secret):
    client = CloudPhoneClient(api_key, api_secret)
    phone = client.connect(instance_id)
    
    # 1. Launch target app
    phone.start_app("com.example.game")
    phone.wait(5)
    
    # 2. Click sign-in button (via image recognition)
    signin_btn = phone.find_by_image("signin_button.png", timeout=10)
    if signin_btn:
        phone.tap(signin_btn.x, signin_btn.y)
        phone.wait(2)
        
        # 3. Claim reward
        reward = phone.find_by_text("Claim Reward")
        if reward:
            phone.tap(reward.x, reward.y)
            phone.wait(1)
            
    # 4. Save screenshot
    screenshot = phone.screenshot()
    with open("signin_result.png", "wb") as f:
        f.write(screenshot)
    
    phone.disconnect()
    return True

# Execute sign-in
auto_signin("cp_12345678", "key", "secret")

5. Common Function Libraries

Several practical function libraries exist in the ChangChang Cloud Phone script ecosystem:

1. Image Recognition Library (cv_helper)

from cv_helper import ImageMatcher

matcher = ImageMatcher(confidence=0.85)
result = matcher.find("button.png", phone.screenshot())
# result contains matched x, y coordinates

2. OCR Text Recognition Library

from ocr_helper import TextRecognizer

ocr = TextRecognizer(lang="en")
text = ocr.recognize(phone.screenshot())
# Returns text content on screen

3. Multi-Instance Management Library

from multi_instance import InstanceManager

manager = InstanceManager(client)
instances = manager.create_batch(count=5, config="standard")
# Batch create 5 standard configuration instances

6. Script Debugging Tips

7. Performance Optimization Tips

1. Reduce screenshot frequency: Screenshots are the most time-consuming operation; use element positioning instead
2. Batch operations: Use batch_tap() to execute multiple clicks at once
3. Async waiting: Use conditional waits instead of fixed sleep
4. Connection reuse: Maintain long connections to avoid frequent reconnections

FAQ

Q: Do I need programming skills for script development? A: Basic scripts can be generated through ChangChang Cloud Phone's visual recording feature without programming. However, for complex logic, learning Python basics is recommended.

Q: Can scripts run on multiple cloud phones simultaneously? A: Yes. The multi-instance management library can manage multiple instances and execute scripts in parallel.

Q: Will script execution be detected as cheating? A: ChangChang Cloud Phone SDK has a built-in human behavior simulation module with randomized operation intervals, reducing detection risk.

Q: How do I get ChangChang Cloud Phone API keys? A: After registering a ChangChang Cloud Phone account, apply for API keys in the console's "Developer Center" page.

Q: What programming languages are supported? A: The official SDK supports Python and Java, while the community edition supports Node.js and Go.
