    Hi!

    i try to implement the QtBluetooth scan devices in an Android application, as service but when i try

    m_deviceDiscoveryAgent = new QBluetoothDeviceDiscoveryAgent(this);
    ...
    m_deviceDiscoveryAgent->start(QBluetoothDeviceDiscoveryAgent::LowEnergyMethod);
    

    i got this error:
    No implementation found for void org.qtproject.qt5.android.bluetooth.QtBluetoothLE.leScanResult

      I found the problem the AndroidManifest.xml missing the loaders of Qt libs :

       <meta-data android:name="android.app.lib_name" android:value="-- %%INSERT_APP_LIB_NAME%% --"/>
                  <meta-data android:name="android.app.qt_sources_resource_id" android:resource="@array/qt_sources"/>
                  <meta-data android:name="android.app.repository" android:value="default"/>
                  <meta-data android:name="android.app.qt_libs_resource_id" android:resource="@array/qt_libs"/>
                  <meta-data android:name="android.app.bundled_libs_resource_id" android:resource="@array/bundled_libs"/>
