Pros of iosched

• Real-world application: iosched is a fully functional app used for Google I/O, providing a comprehensive example of app architecture and features
• Extensive use of Jetpack libraries: Demonstrates implementation of various Jetpack components in a production environment
• Multi-module architecture: Showcases a modular app structure, promoting better separation of concerns and reusability

Cons of iosched

• Complexity: The large-scale nature of the app may be overwhelming for beginners or those looking for simpler examples
• Specific use case: Being tailored for a conference app, some features might not be directly applicable to other types of applications
• Frequent updates: Regular changes to match the latest Google I/O event can make it challenging to follow long-term

Code Comparison

iosched (Kotlin):

@Composable
fun SessionItem(
    session: Session,
    onSessionClick: (String) -> Unit,
    modifier: Modifier = Modifier
) {
    // Session item implementation
}

architecture-samples (Kotlin):

@Composable
fun TaskItem(
    task: Task,
    onCheckboxClicked: (Task, Boolean) -> Unit,
    onTaskClicked: (Task) -> Unit
) {
    // Task item implementation
}

Both repositories use Jetpack Compose for UI, but iosched tends to have more complex composables due to its larger scope and feature set.

Pros of architecture-components-samples

• Focuses specifically on Architecture Components, providing more in-depth examples
• Includes a wider variety of sample apps demonstrating different use cases
• More frequently updated with the latest Android development practices

Cons of architecture-components-samples

• May be overwhelming for beginners due to the large number of samples
• Less emphasis on overall app architecture patterns compared to architecture-samples
• Some samples may be more complex than necessary for learning basic concepts

Code Comparison

architecture-components-samples:

@Dao
interface UserDao {
    @Query("SELECT * FROM users")
    fun getAll(): List<User>

    @Insert
    fun insertAll(vararg users: User)
}

architecture-samples:

@Dao
interface TasksDao {
    @Query("SELECT * FROM Tasks")
    fun getTasks(): LiveData<List<Task>>

    @Insert(onConflict = OnConflictStrategy.REPLACE)
    fun insertTask(task: Task)
}

Both repositories demonstrate similar DAO (Data Access Object) implementations, but architecture-components-samples tends to showcase more specific use cases of Architecture Components, while architecture-samples focuses on integrating these components into a complete app architecture.

Pros of Android-CleanArchitecture

• Focuses on implementing Clean Architecture principles, promoting better separation of concerns
• Provides a more detailed example of dependency injection using Dagger
• Demonstrates advanced testing techniques, including integration and end-to-end tests

Cons of Android-CleanArchitecture

• Less frequently updated compared to architecture-samples
• May be more complex for beginners to understand and implement
• Fewer architecture variants showcased

Code Comparison

Android-CleanArchitecture:

class GetUserDetails @Inject constructor(
    private val userRepository: UserRepository
) : UseCase<GetUserDetails.Params, UserDetails>() {
    override suspend fun run(params: Params) = userRepository.getUserDetails(params.userId)
    data class Params(val userId: Int)
}

architecture-samples:

@Inject
class GetTaskUseCase @Inject constructor(
    private val tasksRepository: TasksRepository
) {
    suspend operator fun invoke(taskId: String): Result<Task> {
        return tasksRepository.getTask(taskId)
    }
}

Both repositories demonstrate the implementation of use cases, but Android-CleanArchitecture uses a more generic approach with a base UseCase class, while architecture-samples opts for a simpler, more direct implementation.

Pros of android-best-practices

• Provides a comprehensive guide covering various aspects of Android development
• Offers practical tips and best practices for real-world scenarios
• Regularly updated with community contributions

Cons of android-best-practices

• Less focused on specific architectural patterns
• Lacks detailed code examples for complex implementations
• May not cover the latest Android features as extensively

Code Comparison

architecture-samples:

class TasksViewModel @Inject constructor(
    private val tasksRepository: TasksRepository
) : ViewModel() {
    private val _items = MutableLiveData<List<Task>>().apply { value = emptyList() }
    val items: LiveData<List<Task>> = _items
}

android-best-practices:

public class MyActivity extends Activity {
    @Override
    protected void onCreate(Bundle savedInstanceState) {
        super.onCreate(savedInstanceState);
        setContentView(R.layout.my_activity);
    }
}

The architecture-samples repository focuses on demonstrating different architectural patterns with detailed implementations, while android-best-practices provides general guidelines and best practices for Android development. The code examples reflect this difference, with architecture-samples showcasing a ViewModel implementation using Kotlin and Dependency Injection, and android-best-practices presenting a basic Activity structure in Java.

Pros of android-guidelines

• More comprehensive coverage of Android development best practices
• Includes guidelines for project structure, code style, and architecture
• Provides detailed explanations and rationale for each guideline

Cons of android-guidelines

• Less focused on specific architectural patterns
• May not be as up-to-date with the latest Android development trends
• Lacks concrete code examples for some guidelines

Code Comparison

architecture-samples:

class TasksViewModel @Inject constructor(
    private val tasksRepository: TasksRepository
) : ViewModel() {
    private val _items = MutableLiveData<List<Task>>().apply { value = emptyList() }
    val items: LiveData<List<Task>> = _items
}

android-guidelines:

public class UserPresenter extends BasePresenter<UserMvpView> {
    @Inject
    public UserPresenter(DataManager dataManager) {
        mDataManager = dataManager;
    }
}

The architecture-samples repository focuses on demonstrating various architectural patterns using Kotlin and modern Android development practices. It provides multiple sample implementations of the same app using different architectures.

On the other hand, android-guidelines offers a broader set of guidelines covering various aspects of Android development, including project structure, coding style, and architectural considerations. It aims to provide a comprehensive guide for Android developers to follow best practices.

While both repositories are valuable resources for Android developers, they serve different purposes. architecture-samples is more hands-on with concrete implementations, while android-guidelines provides a broader set of recommendations for overall Android development practices.

Pros of Sunflower

• Demonstrates modern Android development practices with Jetpack Compose
• Includes more advanced features like data binding and WorkManager
• Offers a more complete and realistic app example

Cons of Sunflower

• May be more complex for beginners to understand
• Focuses primarily on Jetpack Compose, which might not be suitable for all projects
• Less variety in architectural approaches compared to Architecture Samples

Code Comparison

Sunflower (Jetpack Compose):

@Composable
fun PlantListItem(plant: Plant, onClick: () -> Unit) {
    Surface(
        shape = MaterialTheme.shapes.medium,
        modifier = Modifier
            .padding(horizontal = 16.dp, vertical = 8.dp)
            .clickable(onClick = onClick)
    ) {
        // Item content
    }
}

Architecture Samples (XML-based layout):

<layout xmlns:android="http://schemas.android.com/apk/res/android"
    xmlns:app="http://schemas.android.com/apk/res-auto">
    <data>
        <variable name="task" type="com.example.android.architecture.blueprints.todoapp.data.Task" />
    </data>
    <LinearLayout
        android:layout_width="match_parent"
        android:layout_height="wrap_content"
        android:orientation="horizontal">
        <!-- Item content -->
    </LinearLayout>
</layout>

The code comparison highlights the difference between Jetpack Compose's declarative UI approach in Sunflower and the traditional XML-based layouts used in Architecture Samples.
