MobileSharing

MobileSharing

A tool to interact with the "sharing" feature found on Android and iOS. Works with Qt5 and Qt6.

Quick start

Build

Copy the MobileSharing directory into your project, then include the library files with either the MobileSharing.pro QMake project file or the CMakeLists.txt CMake project file.

include(src/thirdparty/MobileSharing/MobileSharing.pri)

add_subdirectory(src/thirdparty/MobileSharing)
target_link_libraries(${PROJECT_NAME} MobileSharing::MobileSharing)

Setup on iOS

You'll need to add the file formats that your app can accept in the Info.plist:

<key>CFBundleDocumentTypes</key>
<array>
  <dict>
    <key>CFBundleTypeName</key>
    <string>Multimedia</string>
    <key>CFBundleTypeRole</key>
    <string>Viewer</string>
    <key>LSHandlerRank</key>
    <string>Alternate</string>
    <key>LSItemContentTypes</key>
    <array>
      <string>public.image</string>
      <string>public.audio</string>
      <string>public.movie</string>
    </array>
  </dict>
</array>

Setup on Android

Sharing files on Android in not trivial. Many steps are needed.

Add this line to the dependencies {} section of build.gradle file:

implementation 'androidx.appcompat:appcompat:1.3.0'
implementation 'androidx.core:core:1.3.0'

And add this line in gradle.properties file:

android.useAndroidX=true

Add these files to your project file:

OTHER_FILES += $${PWD}/src/com/emeric/qmlapptemplate/QShareActivity.java
               $${PWD}/src/com/emeric/utils/QShareUtils.java \
               $${PWD}/src/com/emeric/utils/QSharePathResolver.java

Edit the code and rename these to match your project name:

com/emeric/utils
com.emeric.qmlapptemplate
com_emeric_qmlapptemplate

Then edit the manifest to handle incoming and/or outgoing files:

<!-- Handle incoming urls -->
<intent-filter>
    <action android:name="android.intent.action.SEND"/>
    <category android:name="android.intent.category.DEFAULT"/>
    <data android:mimeType="*/*"/>
</intent-filter>
<intent-filter>
    <action android:name="android.intent.action.VIEW"/>
    <category android:name="android.intent.category.DEFAULT"/>
    <data android:mimeType="audio/*"/>
    <data android:mimeType="video/*"/>
    <data android:mimeType="image/*"/>
    <data android:scheme="file"/>
    <data android:scheme="content"/>
</intent-filter>

<!-- Handle outgoing urls -->
<provider
    android:name="androidx.core.content.FileProvider"
    android:authorities="com.emeric.qmlapptemplate.fileprovider"
    android:exported="false"
    android:grantUriPermissions="true">
    <meta-data
        android:name="android.support.FILE_PROVIDER_PATHS"
        android:resource="@xml/filepaths"/>
</provider>

Then add a /res/xml/filepaths.xml in you Android directory:

<?xml version="1.0" encoding="utf-8"?>
<paths>
    <external-path
        name="external"
        path="." />
    <external-files-path
        name="external_files"
        path="." />
    <cache-path
        name="cache"
        path="." />
    <external-cache-path
        name="external_cache"
        path="." />
    <files-path
        name="files"
        path="." />
    <files-path
        name="export"
        path="export/" />
</paths>

Register

Registering the QML type in C++ in your main.cpp file:

#include <MobileSharing>

int main(int argc, char *argv[])
{
    SharingApplication app(argc, argv);

    MobileSharing::registerQML();

    QQmlApplicationEngine engine;
    engine.load(QUrl(QStringLiteral("qrc:/main.qml")));

    return app.exec();
}
