Okay, I can help you set up the basic structure for the "Gregor-E Library" Android application using Kotlin. This setup will include the main activities, layouts, and navigation logic as you described. Please note that opening PowerPoint files requires specific handling within an Android environment (using Intents and ensuring a PPT viewer app is installed on the device). I'll include a placeholder for this functionality. Due to the repetitive nature of creating buttons for every subject and week, I will demonstrate the structure for the main navigation and one complete path (e.g., Grade 11 -> 1st Quarter -> Oral Comm -> Week 1). You can replicate this pattern for other grades, quarters, subjects, and weeks. plugins { id 'com.android.application' id 'org.jetbrains.kotlin.android' } android { namespace 'com.example.gregor_elibrary' compileSdk 34 // Use a recent SDK version defaultConfig { applicationId "com.example.gregor_elibrary" minSdk 24 // Target API level 24 (Android 7.0) or higher targetSdk 34 versionCode 1 versionName "1.0" testInstrumentationRunner "androidx.test.runner.AndroidJUnitRunner" } buildTypes { release { minifyEnabled false proguardFiles getDefaultProguardFile('proguard-android-optimize.txt'), 'proguard-rules.pro' } } compileOptions { sourceCompatibility JavaVersion.VERSION_1_8 targetCompatibility JavaVersion.VERSION_1_8 } kotlinOptions { jvmTarget = '1.8' } buildFeatures { viewBinding true // Enable View Binding } } dependencies { implementation 'androidx.core:core-ktx:1.13.1' // Use latest stable versions implementation 'androidx.appcompat:appcompat:1.6.1' implementation 'com.google.android.material:material:1.12.0' implementation 'androidx.constraintlayout:constraintlayout:2.1.4' testImplementation 'junit:junit:4.13.2' androidTestImplementation 'androidx.test.ext:junit:1.1.5' androidTestImplementation 'androidx.test.espresso:espresso-core:3.5.1' }
