ResolveInfo items from queryIntentActivityOptions have priority always 0

I'm implementing custom share feature for ACTION_SEND intent. I want to exclude my own app from sharing list. To achieve this I'm getting all suitable activities using getPackageManager().queryIntentActivityOptions(...) and then checking the package.
The problem is that getPackageManager().queryIntentActivityOptions(...) returns me a list of ResolveInfo objects where priority is always 0 and apps are ordered wrong - not like in the default share dialog. Thus apps don't have a proper order in a list and it's not convenient for user.
Here is a code which does sharing:
public void shareExcludingApp(String packageNameToExclude, Uri imagePath) {
List<Intent> targetedShareIntents = new ArrayList<>();
Intent share = new Intent(android.content.Intent.ACTION_SEND);
share.setType("image/*");
List<ResolveInfo> resInfo = mContext.getPackageManager().queryIntentActivities(createShareIntent(imagePath), 0);
if (!resInfo.isEmpty()) {
for (ResolveInfo info : resInfo) {
Intent targetedShare = createShareIntent(imagePath);
if (!info.activityInfo.packageName.equalsIgnoreCase(packageNameToExclude)) {
targetedShare.setPackage(info.activityInfo.packageName);
targetedShareIntents.add(targetedShare);
}
}
Intent chooserIntent = Intent.createChooser(targetedShareIntents.remove(0), mContext.getString(R.string.choose_an_app));
chooserIntent.putExtra(Intent.EXTRA_INITIAL_INTENTS, targetedShareIntents.toArray(new Parcelable[]{}));
mContext.startActivity(chooserIntent);
}
}
private Intent createShareIntent(Uri uri) {
Intent share = new Intent(Intent.ACTION_SEND);
share.setType("image/*");
share.putExtra(Intent.EXTRA_STREAM, uri);
return share;
}
Am I configuring the intent wrong? Do I need to supply more data somewhere?
Thanks
Update:
Thanks to #CommonsWare I realized that I shouldn't use priority to order the list myself, instead the list should be sorted already (queryIntentActivities):
Returns a List of ResolveInfo objects containing one entry for each matching activity, ordered from best to worst.
But it's not sorted properly in my case and I'm getting activities mixed up. Can you please help me?

How to get a list of android installed apps which accept http: as URI?

i guess packagemanager is the starting point but it seems that it is quite complicated.
i want to list the set of supporting app accepting http: in a list with its launcher icon, clicking it will launch the app.
thank you

The following example will show how to get a list of application that can open HTTP URLs.
String url = "http://www.example.com"; // you can give any url here
Intent i = new Intent(Intent.ACTION_VIEW);
i.setData(Uri.parse(url));
List<ResolveInfo> resolveInfoList = getPackageManager()
.queryIntentActivities(i, 0);
for (ResolveInfo resolveInfo : resolveInfoList) {
//you will get all information you need from `resolveInfo`
//eg:for package name - resolveInfo.activityInfo.packageName
}

Custom intent-chooser - why on Android 6 does it show empty cells?

Background
I wish to show the native intent-chooser, while having the ability to customize it a bit.
For this, I've found the next StackOverflow thread:
How to customize share intent in Android?
The problem
Thing is, when I use the suggested code on Android 5.x and below, everything seems to be fine, but when I use it on Android 6.0.1 (tested on Nexus 5 and emulator, when having multiple apps to share content with) , I get empty cells and sometimes even empty app names, as such:
This doesn't appear when using the non-customized intent-chooser:
startActivity(Intent.createChooser(intent, "default chooser"));
The code
Seeing the solutions, I've created the next code:
private void test(Intent shareIntent) {
List<Intent> targetedShareIntents = new ArrayList<>();
final List<ResolveInfo> resInfo = getPackageManager().queryIntentActivities(shareIntent, 0);
if (!resInfo.isEmpty()) {
for (ResolveInfo resolveInfo : resInfo) {
Intent targetedShareIntent = new Intent(shareIntent);
targetedShareIntent.setClassName(resolveInfo.activityInfo.packageName, resolveInfo.activityInfo.name);
targetedShareIntents.add(targetedShareIntent);
}
Intent chooserIntent = Intent.createChooser(targetedShareIntents.remove(targetedShareIntents.size() - 1), "Select app to share");
chooserIntent.putExtra(Intent.EXTRA_INITIAL_INTENTS, targetedShareIntents.toArray(new Parcelable[targetedShareIntents.size()]));
startActivity(chooserIntent);
}
}
private void prepareIntentToShare(Intent intent) {
intent.setAction(android.content.Intent.ACTION_SEND);
intent.setType("image/*");
intent.putExtra(Intent.EXTRA_STREAM, mUri);
intent.putExtra(android.content.Intent.EXTRA_SUBJECT, "title");
intent.putExtra(android.content.Intent.EXTRA_TEXT, "body");
}
And the way to test it:
Intent intent = new Intent();
prepareIntentToShare(intent);
test(intent);
What I've tried
I've tried to change various things in the intents, but without any luck. I've also tried to find out what is the order that the intents are supposed to be in (because maybe it's important), but I didn't find it.
Lastly, I've decided to post about it to Google, assuming this is a bug:
https://code.google.com/p/android/issues/detail?id=202693
The questions
Why does it occur? Can I fix it somehow, while still using the native intent-chooser? How come it occurs only on Android 6 and above?
How can I put the correct name for each item there, as I see "twitter" twice, for example, yet other apps do show the correct name (like the one of the qr-code-scanner)?
Is it possible to keep the native behavior of how to order of apps, as shown using the simple way of showing the intent-chooser? Maybe get the list of apps the way they are supposed to be ordered ?

I spend some time to read ChooserActivity and ResolverActivity and kind of solving thoese problems.
Intent intent = new Intent(Intent.ACTION_SEND);
intent.setType("text/plain");
List<ResolveInfo> resolveInfos = context.getPackageManager().queryIntentActivities(intent, 0);
if (resolveInfos != null && !resolveInfos.isEmpty()) {
List<Intent> targetIntents = new ArrayList<>();
for (ResolveInfo resolveInfo : resolveInfos) {
ActivityInfo activityInfo = resolveInfo.activityInfo;
// remove activities which packageName contains 'ttt' for example
if (activityInfo.packageName.contains("ttt")) {
continue;
}
Intent targetIntent = new Intent(Intent.ACTION_SEND);
targetIntent.setType("text/plain");
targetIntent.putExtra(Intent.EXTRA_SUBJECT, context.getString(R.string.setting_share_app_subject));
targetIntent.putExtra(Intent.EXTRA_TEXT, context.getString(R.string.setting_share_app_body));
targetIntent.setPackage(activityInfo.packageName);
targetIntent.setComponent(new ComponentName(activityInfo.packageName, activityInfo.name));
// wrap with LabeledIntent to show correct name and icon
LabeledIntent labeledIntent = new LabeledIntent(targetIntent, activityInfo.packageName, resolveInfo.labelRes, resolveInfo.icon);
// add filtered intent to a list
targetIntents.add(labeledIntent);
}
Intent chooserIntent;
// deal with M list seperate problem
if (Build.VERSION.SDK_INT >= Build.VERSION_CODES.M) {
// create chooser with empty intent in M could fix the empty cells problem
chooserIntent = Intent.createChooser(new Intent(), context.getString(R.string.setting_share_app_title));
} else {
// create chooser with one target intent below M
chooserIntent = Intent.createChooser(targetIntents.remove(0), context.getString(R.string.setting_share_app_title));
}
if (chooserIntent == null) {
return;
}
// add initial intents
chooserIntent.putExtra(Intent.EXTRA_INITIAL_INTENTS, targetIntents.toArray(new Parcelable[targetIntents.size()]));
try {
context.startActivity(chooserIntent);
} catch (ActivityNotFoundException e) {
Logger.e(TAG, e, e);
}
}
EDIT: seems on Android Q (10 - API 29) this is broken, and will show just up to 2 items instead of all of them. Asked about this again here.
EDIT: made a sample of choosing which items to exclude from sharing, here, which should work for all Android versions.

Checking through intent if user has certain messaging app installed android

I am working with this code which Ragu Swaminathan helped me with on my original post found at: How to show both texting and dialer apps with a single Intent on Android?.
final List<Intent> finalIntents = new ArrayList<Intent>();
final Intent textIntent = new Intent(Intent.ACTION_VIEW);
textIntent.setType("text/plain");
textIntent.setData(Uri.parse("sms:"));
final PackageManager packageManager = getActivity().getPackageManager();
final List<ResolveInfo> listCam = packageManager.queryIntentActivities(textIntent, 0);
for (ResolveInfo res : listCam) {
final String packageName = res.activityInfo.packageName;
final Intent intent = new Intent(textIntent);
intent.setComponent(new ComponentName(res.activityInfo.packageName, res.activityInfo.name));
intent.setPackage(packageName);
finalIntents.add(intent);
}
Intent callIntent = new Intent(Intent.ACTION_DIAL);
callIntent.setData(Uri.parse("tel:121"));
Intent chooserIntent = Intent.createChooser(
callIntent, "Select app to share");
chooserIntent.putExtra(
Intent.EXTRA_INITIAL_INTENTS, finalIntents.toArray(new Parcelable[]{}));
startActivity(chooserIntent);
I have this code that brings up snackup separating sms and dialer apps installed on users phone and allows them to pick one to either send a message / call a person.
What I want to know is, is it possbile to add another section on this snackbar that checks if the user has whatsapp installed or another specfic app installed.
Also, being new to android, I have tried playing around with the code but ended up messing it up. another thing that I would like to do is create sections like theses;
Sms apps:
.....
.....
.....
Dialer apps:
.....
.....
.....
Whatsapp:
.....
Any help is welcomed, please let me know if my question is not clear.

You can use getPackageInfo method
PackageManager pm = getPackageManager();
PackageInfo pi = pm.getPackageInfo(certainAppPackageName, 0);
if (pi != null) {
//app is installed, do smth
}
Google play links exist package names.
For example:
https://play.google.com/store/apps/details?id=org.telegram.messenger
where org.telegram.messenger is a package name

how to get a list of installed video players programmatically?

I know its similar to this question How to get a list of installed media players, but I am not able to get a list of installed players. Can someone help me on this?
Intent intent = new Intent(Intent.ACTION_VIEW); Uri uri = Uri.withAppendedPath(MediaStore.Video.Media.INTERNAL_CONTENT_URI,"1"); intent.setData(uri);
playerList = packageManager.queryIntentActivities(intent, 0);

Intent resolveIntent = new Intent(Intent.ACTION_VIEW);
resolveIntent.setDataAndType(Uri.parse("file://"), MIMEType);
List<ResolveInfo> pkgAppsList = mContext.getPackageManager().queryIntentActivities(resolveIntent, PackageManager.MATCH_DEFAULT_ONLY| PackageManager.GET_RESOLVED_FILTER);
