Remote Debugging: Real-Time Debug from Your Phone

Debugging is an essential part of development. Pocket Code includes professional debug tools that work directly from your Android device.

Available debugging tools

Breakpoints

Tap on a line number to set a breakpoint. Code will pause at that point so you can inspect variables:

def calculate_price(product, quantity):
    subtotal = product.price * quantity  # ← Breakpoint here
    discount = apply_discount(subtotal)
    total = subtotal - discount
    return total

Variables panel

When code is paused at a breakpoint, the side panel shows:

• Local variables — Values in the current scope
• Global variables — Application global state
• Watch expressions — Custom expressions you monitor
• Call stack — The call stack to the current point

Interactive console

Execute expressions while code is paused:

> subtotal
150.00
> discount
22.50
> product.name
"Mechanical Keyboard"

Remote debugging

Connect your debug session to a remote server:

Configuration

1. Open Settings > Debug > Remote
2. Enter the server IP and port
3. Select the protocol (DAP, Chrome DevTools, etc.)
4. Tap Connect

Supported protocols

Protocol	Languages	Default port
DAP	Python, Node.js, C++	5678
Chrome DevTools	JavaScript, TypeScript	9229
JDWP	Java, Kotlin	5005
Delve	Go	2345

Example: Debugging a Node.js app

On your server, start the app in debug mode:

node --inspect=0.0.0.0:9229 app.js

In Pocket Code, connect to the server:

{
	"type": "node",
	"request": "attach",
	"address": "192.168.1.100",
	"port": 9229,
	"localRoot": "${workspaceFolder}",
	"remoteRoot": "/app"
}

Tips for efficient debugging

1. Conditional breakpoints: Only pause when a condition is met
2. Logpoints: Print messages without stopping execution
3. Step Over/Into/Out: Navigate through code step by step
4. Hot Reload: Changes apply without restarting the session
5. Snapshots: Save state for later comparison

Performance profiling

Besides debug, Pocket Code includes profiling tools:

• CPU Profiler — Identify slow functions
• Memory Profiler — Detect memory leaks
• Network Monitor — Analyze HTTP requests
• Flame Graph — Visualize execution time

With Pocket Code's debugging tools, finding and fixing bugs is as efficient from mobile as it is from a PC. Configure your debug environment and improve your code quality.
