Question

I’m trying to find default Intent which device is using to support specific mime type, code like:

    PackageManager pm = this.getPackageManager();
    Intent intent = new Intent(Intent.ACTION_VIEW);
    intent.setDataAndType(uri, mimeType);
    List<ResolveInfo> lri = pm.queryIntentActivities(intent, 0);
    for(ResolveInfo resolveInfo:lri)
    {
        if(Me.DEBUG)
            Log.i(TAG, "Resolved intent="+resolveInfo.activityInfo.packageName+
                    ", default="+resolveInfo.isDefault+
                    ", order="+resolveInfo.preferredOrder+
                    ", match="+resolveInfo.match+
                    ", priority="+resolveInfo.priority);
        if(resolveInfo.isDefault)
        {
            intent=pm.getLaunchIntentForPackage(resolveInfo.resolvePackageName);
            intent.setDataAndType(uri, mimeTypes.getMimeTypeString(name));
            break;
        }
    }
    return intent; 

What’s wrong with this code? ResolveInfo never returns default one… Logcat reports always the same, like:

Resolved intent=com.android.htmlviewer, default=false, order=0,
match=6324224, priority=0 Resolved intent=com.sec.print.mobileprint,
default=false, order=0, match=6324224, priority=0 Resolved
intent=com.qo.android.htc, default=false, order=0, match=6324224,
priority=0 Resolved intent=org.coolreader, default=false, order=0,
match=6324224, priority=0 Resolved intent=xcxin.filexpert,
default=false, order=0, match=6324224, priority=0 Resolved
intent=com.opera.browser, default=false, order=0, match=6324224,
priority=0 Resolved intent=com.dropbox.android, default=false,
order=0, match=6324224, priority=0

Though there’s default marked user as “make this the default” checkbox on the chooser!

Answer 1

Here, “default” means the user set a default, by having this Intent invoked previously and checking the “make this the default” checkbox on the chooser. If that has not already been done, there is no default.
