Base Exception

MobileUseError

Base exception for all SDK errors.

from minitap.mobile_use.sdk.types.exceptions import MobileUseError

try:
    await agent.run_task(goal="...")
except MobileUseError as e:
    print(f"SDK error: {e}")

Use this to catch any SDK-related error.

Agent Exceptions

AgentError

Base exception for agent-related errors.

from minitap.mobile_use.sdk.types.exceptions import AgentError

try:
    await agent.run_task(goal="...")
except AgentError as e:
    print(f"Agent error: {e}")

AgentNotInitializedError

Raised when agent methods are called before initialization. Common cause: Calling run_task() before init()

from minitap.mobile_use.sdk.types.exceptions import AgentNotInitializedError

agent = Agent()

try:
    # This will raise AgentNotInitializedError
    await agent.run_task(goal="Check notifications")
except AgentNotInitializedError:
    print("Agent not initialized. Call agent.init() first.")

Solution:

agent = Agent()
agent.init()  # Initialize first
await agent.run_task(goal="Check notifications")

AgentProfileNotFoundError

Raised when a specified profile is not found. Common cause: Using a profile name that hasn’t been registered

from minitap.mobile_use.sdk.types.exceptions import AgentProfileNotFoundError

try:
    await agent.run_task(
        goal="Some task",
        profile="non_existent_profile"
    )
except AgentProfileNotFoundError as e:
    print(f"Profile not found: {e}")

Solution:

# Ensure profile is registered
profile = AgentProfile(name="my_profile", from_file="config.jsonc")
config = Builders.AgentConfig.add_profile(profile).build()
agent = Agent(config=config)

AgentTaskRequestError

Raised for task request validation errors. Common causes:

Invalid task configuration
Conflicting parameters

from minitap.mobile_use.sdk.types.exceptions import AgentTaskRequestError

try:
    # Invalid configuration
    task = agent.new_task("").build()  # Empty goal
except AgentTaskRequestError as e:
    print(f"Invalid task request: {e}")

AgentInvalidApiKeyError

Raised when the Minitap API key is invalid or unauthorized. Common causes:

Incorrect API key
Expired API key
API key not set

from minitap.mobile_use.sdk.types.exceptions import AgentInvalidApiKeyError
from minitap.mobile_use.sdk.types import PlatformTaskRequest

try:
    # Using invalid API key
    result = await agent.run_task(
        request=PlatformTaskRequest(
            task="check-notifications",
            api_key="invalid_key"
        )
    )
except AgentInvalidApiKeyError:
    print("Invalid API key. Get a new one from https://platform.mobile-use.ai/api-keys")

Solution:

# Set valid API key in .env
MINITAP_API_KEY=your_valid_key_here
MINITAP_BASE_URL=https://platform.mobile-use.ai/api/v1  # Optional, this is the default

Device Exceptions

DeviceError

Base exception for device-related errors.

from minitap.mobile_use.sdk.types.exceptions import DeviceError

try:
    agent.init()
except DeviceError as e:
    print(f"Device error: {e}")

DeviceNotFoundError

Raised when no device is found or device becomes disconnected. Common causes:

No device connected
USB debugging not enabled
Device unplugged during operation

from minitap.mobile_use.sdk.types.exceptions import DeviceNotFoundError

try:
    agent.init()
except DeviceNotFoundError:
    print("No device found. Please connect a device and enable USB debugging.")

Solutions:

Check device connection:

# Android
adb devices

# iOS
idevice_id -l

Enable USB debugging (Android)
Specify device explicitly:

config = (
    Builders.AgentConfig
    .for_device(platform=DevicePlatform.ANDROID, device_id="your_device_id")
    .build()
)

Server Exceptions

ServerError

Base exception for server-related errors.

from minitap.mobile_use.sdk.types.exceptions import ServerError

try:
    agent.init()
except ServerError as e:
    print(f"Server error: {e}")

ServerStartupError

Raised when server startup fails. Common causes:

Port already in use
Missing dependencies (ADB for Android, idb for iOS)
Permission issues

from minitap.mobile_use.sdk.types.exceptions import ServerStartupError

try:
    agent.init()
except ServerStartupError as e:
    print(f"Failed to start servers: {e}")

Solutions:

Kill zombie servers:

agent.clean(force=True)  # Clean up existing servers
agent.init()

Verify platform tools are installed:

# Android
adb version

# iOS
idb --help

Executable Exceptions

ExecutableNotFoundError

Raised when required system executables are not found in PATH. Common causes:

adb not installed (for Android)
idb not installed (for iOS)
xcrun not installed (for iOS on macOS)

from minitap.mobile_use.sdk.types.exceptions import ExecutableNotFoundError

try:
    agent.init()
except ExecutableNotFoundError as e:
    print(f"Missing executable: {e}")

Solutions:

Install ADB (for Android):

# Visit: https://developer.android.com/tools/adb
# Or use package manager
brew install android-platform-tools  # macOS
sudo apt install adb                 # Linux

Install idb (for iOS):

brew install idb-companion

Install Xcode Command Line Tools (for iOS):

xcode-select --install

Platform Exceptions

PlatformServiceUninitializedError

Raised when attempting to use platform features without proper initialization. Common causes:

MINITAP_API_KEY not set in environment
No API key provided in PlatformTaskRequest
Platform service not configured

from minitap.mobile_use.sdk.types.exceptions import PlatformServiceUninitializedError
from minitap.mobile_use.sdk.types import PlatformTaskRequest

try:
    # Missing API key
    result = await agent.run_task(
        request=PlatformTaskRequest(task="check-notifications")
    )
except PlatformServiceUninitializedError:
    print("Platform service not initialized. Set MINITAP_API_KEY in .env")

Solution:

# Add to .env file
MINITAP_API_KEY=your_api_key_here
MINITAP_BASE_URL=https://platform.mobile-use.ai/api/v1  # Optional, this is the default

Or provide API key directly:

result = await agent.run_task(
    request=PlatformTaskRequest(
        task="check-notifications",
        api_key="your_api_key_here"
    )
)

PlatformServiceError

Base exception for platform service-related errors. Common causes:

Network connectivity issues
Platform API errors
Invalid task configuration on platform

from minitap.mobile_use.sdk.types.exceptions import PlatformServiceError

try:
    result = await agent.run_task(
        request=PlatformTaskRequest(task="my-task")
    )
except PlatformServiceError as e:
    print(f"Platform service error: {e}")

Solutions:

Check network connectivity
Verify task exists on platform
Check platform status at platform.mobile-use.ai

Exception Handling Best Practices

1. Always Clean Up

agent = Agent()

try:
    agent.init()
    await agent.run_task(goal="...")
except MobileUseError as e:
    print(f"Error: {e}")
finally:
    agent.clean()  # Always clean up

2. Handle Specific Exceptions

from minitap.mobile_use.sdk.types.exceptions import (
    AgentNotInitializedError,
    DeviceNotFoundError,
    ServerStartupError,
    ExecutableNotFoundError,
    PlatformServiceUninitializedError,
    AgentInvalidApiKeyError,
)

try:
    agent.init()
    await agent.run_task(goal="...")
    
except ExecutableNotFoundError as e:
    print(f"Missing required executable: {e}")
    
except DeviceNotFoundError:
    print("Please connect a device")
    
except ServerStartupError:
    print("Server startup failed. Try agent.clean(force=True)")
    
except AgentNotInitializedError:
    print("Call agent.init() first")
    
except PlatformServiceUninitializedError:
    print("Platform service not initialized. Set MINITAP_API_KEY")
    
except AgentInvalidApiKeyError:
    print("Invalid API key. Visit https://platform.mobile-use.ai/api-keys")
    
except Exception as e:
    print(f"Unexpected error: {e}")
    raise

3. Check Initialization

agent = Agent()

if not agent.init():
    print("Initialization failed")
    exit(1)

# Safe to proceed
await agent.run_task(goal="...")

4. Retry Logic

import time

max_retries = 3
for attempt in range(max_retries):
    try:
        agent.init()
        break
    except ServerStartupError:
        if attempt < max_retries - 1:
            print(f"Retry {attempt + 1}/{max_retries}")
            agent.clean(force=True)
            time.sleep(2)
        else:
            raise

        print("Get a valid key from https://platform.mobile-use.ai/api-keys")

        raise
