package com.example.app

import android.content.Context
import androidx.datastore.core.DataStore
import androidx.datastore.core.DataStoreFactory
import androidx.datastore.dataStoreFile
import com.reveny.nativecheck.datastore.AppSettingsDataStore
import com.reveny.nativecheck.datastore.AppSettingsSerializer
import com.reveny.nativecheck.datastore.model.AppSettings
import com.reveny.nativecheck.repository.AppSettingsRepository
import dagger.Module
import dagger.Provides
import dagger.hilt.InstallIn
import dagger.hilt.android.qualifiers.ApplicationContext
import dagger.hilt.components.SingletonComponent
import javax.inject.Singleton

@Module
@InstallIn(SingletonComponent::class)
object AppModule {

    @Provides
    @Singleton
    fun provideAppSettingsDataStore(
        @ApplicationContext context: Context
    ): DataStore<AppSettings> {
        return DataStoreFactory.create(
            serializer = AppSettingsSerializer,
            produceFile = { context.dataStoreFile("app_settings.pb") }
        )
    }

    @Provides
    @Singleton
    fun provideAppSettingsDataStore(
        dataStore: DataStore<AppSettings>
    ): AppSettingsDataStore {
        return AppSettingsDataStore(dataStore)
    }

    @Provides
    @Singleton
    fun provideAppSettingsRepository(
        appSettingsDataStore: AppSettingsDataStore
    ): AppSettingsRepository {
        return AppSettingsRepository(appSettingsDataStore)
    }
}

// Application class setup
@HiltAndroidApp
class SecurityApp : Application() {
    override fun onCreate() {
        super.onCreate() 
        println("Security detection app initialized")
    }
}
```

class SecurityCheckActivity : AppCompatActivity() {
    private val viewModel: MainViewModel by viewModels()

    override fun onCreate(savedInstanceState: Bundle?) {
        super.onCreate(savedInstanceState)

        // Initialize device information
        viewModel.initializeData(this)

        // Observe loading state
        lifecycleScope.launch {
            viewModel.isLoading.collect { isLoading ->
                if (isLoading) {
                    showLoadingIndicator()
                } else {
                    hideLoadingIndicator()
                }
            }
        }

        // Observe detection results
        lifecycleScope.launch {
            viewModel.detections.collect { detections ->
                updateDetectionList(detections)
            }
        }

        // Observe device information
        lifecycleScope.launch {
            launch { viewModel.deviceInfo.collect { info -> displayDeviceInfo(info) } }
            launch { viewModel.androidVersion.collect { version -> displayAndroidVersion(version) } }
            launch { viewModel.kernelVersion.collect { kernel -> displayKernelVersion(kernel) } }
            launch { viewModel.appVersion.collect { appVer -> displayAppVersion(appVer) } }
            launch { viewModel.signature.collect { sig -> displaySignature(sig) } }
        }

        // Perform the detection task
        viewModel.performTask(this, packageManager, enableExperimental = true)
    }

    private fun updateDetectionList(detections: List<DetectionData>) {
        // Update UI with detection results
    }

    private fun showLoadingIndicator() { /* Show progress */ }
    private fun hideLoadingIndicator() { /* Hide progress */ }
    private fun displayDeviceInfo(info: String) { /* Update UI */ }
    private fun displayAndroidVersion(version: String) { /* Update UI */ }
    private fun displayKernelVersion(kernel: String) { /* Update UI */ }

### Kotlin Native Detection Interface for Root Detection

Source: https://context7.com/reveny/android-native-root-detector/llms.txt

This Kotlin code demonstrates how to use the `Native` class to perform root and system modification detection on Android. It initializes the native detector, enables experimental checks, and processes the results, handling potential `UnsatisfiedLinkError` if the native library is not loaded.

```kotlin
package com.example.app

import android.content.Context
import android.content.pm.PackageManager
import com.reveny.nativecheck.app.Native
import com.reveny.nativecheck.app.DetectionData

// Initialize the native detector and perform security checks
fun performRootDetection(context: Context, packageManager: PackageManager) {
    val native = Native()

    // Enable experimental detections for more comprehensive checking
    val enableExperimental = true

    try {
        // Retrieve all detections from native library
        val detections: Array<DetectionData> = native.getDetections(
            context = context,
            pm = packageManager,
            enableExperimental = enableExperimental
        )

        // Process detection results
        if (detections.isNotEmpty()) {
            println("Root or modifications detected:")
            detections.forEach { detection ->
                println("${detection.name}: ${detection.description}")
            }
        } else {
            println("No root or system modifications detected")
        }
    } catch (e: UnsatisfiedLinkError) {
        println("Native library not loaded: ${e.message}")
    }
}
```

Processes an array of security detection findings, categorizing them by severity (critical or warning) and generating a security report. It also provides functionality to create custom detection data. Dependencies include the DetectionData model.

```Kotlin
package com.example.app

import com.reveny.nativecheck.app.DetectionData

// Creating and processing detection results
class DetectionProcessor {

    fun processDetections(detections: Array<DetectionData>) {
        val criticalDetections = mutableListOf<String>()
        val warningDetections = mutableListOf<String>()

        detections.forEach { detection ->
            println("Detection: ${detection.name}")
            println("Details: ${detection.description}")
            println("---")

            // Categorize detections by severity
            if (isCritical(detection.name)) {
                criticalDetections.add(detection.name)
            } else {
                warningDetections.add(detection.name)
            }
        }

        // Generate security report
        val report = generateSecurityReport(criticalDetections, warningDetections)
        saveReport(report)
    }

    fun createCustomDetection(name: String, description: String): DetectionData {
        return DetectionData(
            name = name,
            description = description
        )
    }

    private fun isCritical(detectionName: String): Boolean {
        val criticalKeywords = listOf("root", "superuser", "magisk", "su", "busybox")
        return criticalKeywords.any { detectionName.lowercase().contains(it) }
    }

    private fun generateSecurityReport(
        critical: List<String>,
        warnings: List<String>
    ): String {
        return buildString {
            appendLine("=== Security Report ===")
            appendLine("Critical Detections: ${critical.size}")
            critical.forEach { appendLine("  - $it") }
            appendLine("Warning Detections: ${warnings.size}")
            warnings.forEach { appendLine("  - $it") }
            appendLine("=====================")
        }
    }

    private fun saveReport(report: String) {
        // Save report to file or database
    }
}
