      Description

      When I try to open a file under Android 9.0 my app crashes.

      I use the QML FileDialog to get the URI. It seems that the URI has to following format

      content://com.android.externalstorage.documents/documents/primary:<myFile>

      QFile code 

      QFile myFile("content://com.android.externalstorage.documents/documents/primary:<myFile>");
      myFile.open(QIODevice::ReadOnly)

      When I pass this URI to QFile the app crashes with the error

      JNI DETECTED ERROR IN APPLICATION: JNI GetStaticMethodID called with pending exception java.lang.SecurityException: Permission Denial: reading com.android.externalstorage.ExternalStorageProvider uri :xxxxx

      Inside the AndroidManifest.xml the READ_EXTERNAL_STORAGE is added 

      <uses-permission android:name="android.permission.READ_EXTERNAL_STORAGE"/>
