Functions

• Verify storage permissions
• Vibrate
• Screen wake
• Android system directory
• Message notifiction
• Call system album and camera
• Share

Build

• Use Qtcreate open QtAndroidUtils.pro
• build
• Generate library
  • JNI(*.so) : libQtAndroidUtilsModule.so
  • Android(.aar): QtAndroidUtilsModule-.aar

Other application use the library

• Introduce this project to the application source tree

  • If the application hasn't its own android source code

    • Add the project to the application

      $ cd application_root
      $ git submodule add https://github.com/KangLin/QtAndroidUtils.git android
      

    • Add android/android.pri to application's main profile

      $ cd application_root
      $ vim application.pro
      android: include(android/android/android.pri)
      

  • If the application has its own android source code. ag: application_root/android

    $ ls application_root/android
    android.pri  AndroidManifest.xml  build.gradle  jni/  src/
    

    • then git submodle from this project to the application's android directory:

       $ cd application_root/android  
       $ git submodule add https://github.com/KangLin/QtAndroidUtils.git
      

    • Add jni module to application project file

      • qmake project: android.pri

        $ cd application_root/android
        $ vim android.pri
        # Add jni
        android {
            # Include pri
            include(QtAndroidUtils/android/QtAndroidUtilsModule/jni/jni.pri)
            # Include header files path
            INCLUDEPATH *= QtAndroidUtils/android/QtAndroidUtilsModule/jni
        }
        

      • cmake project

        $ cd application_root
        $ vim CMakeLists.txt
        add_subdirectory(android/QtAndroidUtils/android/QtAndroidUtilsModule/jni)
        

    • Add java module

      • Generate module library: add the following code to settings.gradle

        $ cd application_root/android
        $ vim settings.gradle
        // Add to compile aar module
        include ':QtAndroidUtils/android/QtAndroidUtilsModule'
        

      • Modify build.gradle to add implementation project(':QtAndroidUtils/android/QtAndroidUtilsModule') to dependencies

        $ cd application_root/android
        $ vim build.gradle
        dependencies {
            // Add aar project
            implementation project(':QtAndroidUtils/android/QtAndroidUtilsModule')
        }
        

• Use as a library

  • Android (*.aar)

    • Copy QtAndroidUtilsModule-release.aar to libs

    • Add the following code to build.gradle

      $ cd application_root/android
      $ vim build.gradle
      repositories {
          flatDir {
              dirs 'libs'
          }
      }
      

    • add the following code to dependencies

      $ cd application_root/android
      $ vim build.gradle
      dependencies {
          // Add aar module
          implementation (name:'QtAndroidUtilsModule-release',ext:'aar')
      }
      

  • JNI (*.so)

    • qmake project

      • Import library: libQtAndroidUtilsModule.so
      • inlude heade files

    • cmake project

      find_package(QtAndroidUtilsModule)
