Intents on QT android

RahulRaj

Can we use intents on Qt for android ? I need to open a pdf file from the sd card. Once i select a file using the UI, i need to get a list of applications which can open that file( using intents).

In short, how can we raise an intent in QT for android ?

Hi,

The correct Qt way of opening a local file is using
@QDesktopServices::openUrl((QUrl("file:///sdcard/temp/file.pdf")))@

In Qt4 on Android (Neccessitas), I filed a bug on this some years ago:
"https://bugs.kde.org/show_bug.cgi?id=307605":https://bugs.kde.org/show_bug.cgi?id=307605

I don't know for sure the current status on this in Qt5, but please go ahead and file a bugreport if it's not fixed.

My workaround for this at the moment is using Android intents like this (using JNI - java code):
@import android.net.Uri;
import android.provider.MediaStore;
import android.webkit.MimeTypeMap;

...

public void JIntentActionViewFile&#40;final String data&#41;
{
    Intent intent = new Intent(Intent.ACTION_VIEW);
    MimeTypeMap mime = MimeTypeMap.getSingleton();
    File file = new File&#40;data&#41;;
    String ext=file.getName().substring(file.getName().lastIndexOf(".")+1).toLowerCase();
    String type = mime.getMimeTypeFromExtension(ext);
    intent.setDataAndType(Uri.fromFile&#40;file&#41;,type);
    QtActivity.startActivity(intent);
}
