Question

Hi I’m working on an app where I need to list all types of applications able to open a file. If the file were an image I would do something like this normally to show all applications capable of viewing the image.

Intent intent = new Intent();
intent.setAction(android.content.Intent.ACTION_VIEW);
intent.setDataAndType(Uri.fromFile(file), "image/*");
context.startActivity(intent);

However say I have an unknown file how could I list all applications able to view a file so the user can select the appropriate application to open the file in my application.

I also need the titles listed in an arraylist if possible so I can list them in a listview.

Thank you for any help with getting a list of applications capable of viewing a file

Edit

Alright well something easier how can i get the applications from the above intent into an arraylist i could just do image/* audio/* etc and add them all to a list and then list them in a listview and that would solve my problem

Answer 1

Okay well i figured my problem out what i was looking for was

    Intent audioIntent = new Intent(android.content.Intent.ACTION_VIEW);
    audioIntent.setDataAndType(Uri.fromFile(Opener.file), "audio/*");
    List<ResolveInfo> audio = packageManager.queryIntentActivities(audioIntent, 0);
    for (ResolveInfo info : audio){
        String label = info.loadLabel(packageManager).toString();
        Drawable icon = info.loadIcon(packageManager);
        String packageName = info.activityInfo.packageName;
        String name = info.activityInfo.name;
        iconlabel.add(a.new HolderObject(label, icon, audioIntent, "audio/*", packageName, name));
    }

But the main thing in the code above is the queryIntentActivities method that was what solved my issue allowing me to add those apps to a list
