Test Workflow Fixed +**Problem**: Tests were failing because coverage XML file wasn't being generated. + +**Solution**: +- Updated `.github/workflows/tests.yml` to use `--cov-report=xml` flag +- Added `--cov-report=term` for console output during CI +- Limited codecov upload to one Python version (3.11) to avoid redundant uploads +- Removed Python 3.7 support (EOL) + +### 2. Backend Import Error Handling +**Problem**: The backend module would crash when Kivy wasn't installed, even in console-only mode. + +**Solution**: +- Updated `pyandroid/backend/__init__.py` to gracefully handle ImportError +- Set `KivyRenderer = None` when Kivy is unavailable +- Updated `AndroidApp` to properly check for None before using renderer + +### 3. Activity Lifecycle State Validation +**Problem**: Activity state transitions weren't validated, allowing invalid transitions. + +**Solution**: +- Added `VALID_TRANSITIONS` dictionary to Activity class +- Implemented `_validate_transition()` method +- All lifecycle methods now validate state transitions +- Raises `InvalidStateError` for invalid transitions + +## New Features + +### 1. Custom Exception Classes +Added three custom exception types for better error handling: + +```python +from pyandroid.core import PyAndroidError, ActivityNotFoundError, InvalidStateError + +# PyAndroidError - Base exception +# ActivityNotFoundError - Raised when activity not registered +# InvalidStateError - Raised on invalid state transitions +``` + +### 2. Enhanced Type Hints +- Added comprehensive type hints throughout `core.py` +- Added return type annotations to all methods +- Improved IDE autocomplete and static analysis support + +### 3. Activity Extras Support +- Activities now accept `**kwargs` during initialization +- Extras stored in `activity.extras` dictionary +- Useful for passing data between activities + +```python +activity = Activity("DetailActivity", user_id=123, username="alice") +print(activity.extras["user_id"]) # 123 +``` + +### 4. Intent Enhancements +Added new Intent methods: +- `has_extra(key)` - Check if extra exists +- `get_all_extras()` - Get all extras as dictionary + +### 5. Activity View Management +Added `remove_view()` method: + +```python +activity.add_view("text1", text_view) +activity.remove_view("text1") # Returns True if removed +``` + +## Code Quality Improvements + +### 1. Comprehensive Documentation +- Added docstring examples to all major classes and methods +- Included usage examples in docstrings +- Better parameter descriptions + +### 2. Test Suite Enhancements + +**New Test Features**: +- Added pytest fixtures for common test objects +- Reduced code duplication across tests +- Added tests for exception handling +- Added tests for state validation +- Added tests for new features (extras, remove_view, etc.) +- Created `conftest.py` for shared test configuration + +**Test Coverage Improvements**: +- Core tests increased from 3 to 9 test classes +- UI tests increased from 5 to 8 test classes +- Added edge case testing +- Added negative test cases + +### 3. Better Error Messages +Improved error messages with context: + +```python +# Before +ValueError: Activity not registered + +# After +ActivityNotFoundError: Activity 'details' not registered. +Available activities: ['main', 'settings'] +``` + +### 4. Activity Switching +Improved activity switching logic: +- Properly stops and destroys previous activity +- Prevents resource leaks +- Maintains clean state transitions + +## Configuration Updates + +### 1.
