Introduction

This project is a basic Android application developed using Qt that demonstrates:

Swipe navigation between multiple views.
Building and deploying Qt applications for Android.

The app is packaged as an APK and can be deployed to an emulator or physical device for testing. Features

Swipe View UI: Navigate between multiple views using swipe gestures.
Simple Design: Displays a "Hello World" message on each view.
Cross-Platform Development: Built using Qt for Android.

Prerequisites

Ensure you have the following installed and configured:

Operating System: Linux (e.g., Ubuntu)
Qt Framework: Download and install Qt with Android support from Qt Downloads.
Android SDK and NDK: Install the required SDK tools, platforms, and NDK.
Build Tools:
    CMake
    adb (Android Debug Bridge)
    Android toolchain (for cross-compilation)

Development Steps

1. Set Up the Development Environment

   Install Qt And settup it: sudo apt update Download the necessary components for Android development from the Qt Maintenance Tool. wget https://download.qt.io/official_releases/online_installers/qt-unified-linux-x64-online.run chmod +x qt-unified-linux-x64-online.run ./qt-unified-linux-x64-online.run apt install libxcb-cursor0 libxcb-cursor-dev' sudo apt install build-essential openjdk-17-jdk unzip git cmake ninja-build libgl1-mesa-dev -y
   wget https://dl.google.com/android/repository/commandlinetools-linux-9477386_latest.zip unzip commandlinetools-linux-9477386_latest.zip -d $HOME/Android export ANDROID_HOME=$HOME/Android export PATH=$ANDROID_HOME/cmdline-tools/latest/bin:$ANDROID_HOME/platform-tools:$PATH mkdir -p $ANDROID_HOME/cmdline-tools/latest mv $ANDROID_HOME/cmdline-tools $ANDROID_HOME/cmdline-tools/latest sdkmanager --channel=3 "platform-tools" "platforms;android-33" "build-tools;33.0.0" "ndk;26.1.10909125"

   install neccessary tool and library with MaintenanceTool like this:

   Configure the Qt Android Toolchain: Open Qt Creator. Navigate to Prefrence > Kits > Android. Set the paths for Android SDK, NDK, JDK, and ant. like these photos:

2. Create the Application

   Create a new Qt Quick Application project in Qt Creator: File > New Project > Application (Qt Quick) > Swipe View UI. Use a basic template or design your views manually.

   Implement swipe navigation: Use SwipeView from Qt Quick Controls. Example:

    SwipeView {
        id: swipeView
      anchors.fill: parent
   
      Page {
          Label {
              anchors.centerIn: parent
              text: "Hello, World! Page 1"
          }
      }
   
      Page {
          Label {
              anchors.centerIn: parent
              text: "Hello, World! Page 2"
          }
      }
   
      Page {
          Label {
              anchors.centerIn: parent
              text: "Hello, World! Page 3"
          }
      }
    }
   

3. Build & Package the Application

   Select the Android Kit in Qt Creator. Configure the build system: Use CMake for project configuration. Build the project: /opt/Qt/Tools/CMake/bin/cmake --build /root/HelloWorldSwipe/build/Android_Qt_6_8_0_Clang_arm64_v8a-Debug --target all /opt/Qt/6.8.0/gcc_64/bin/androiddeployqt --input /root/HelloWorldSwipe/build/Android_Qt_6_8_0_Clang_arm64_v8a-Debug/android-appHelloWorldSwipe-deployment-settings.json --output /root/HelloWorldSwipe/build/Android_Qt_6_8_0_Clang_arm64_v8a- Debug/android-build-appHelloWorldSwipe --android-platform android-34 --jdk /usr/lib/jvm/java-1.17.0-openjdk-amd64 --gradle

4. Deploy on Emulator or Device

   Deploy using adb:

   Verify functionality on the emulator or physical device: Launch the app and test swipe functionality.
