Is it possible to exclude apps and directshare?

I want to use the directshare feature, but i need to exclude apps.
The excluding part works pretty well, i am just giving an array of intents to the chooser, while the intents are only including one specific application.
But doing this directshare does not work.
Directshare only seems to be working when giving exactly one intent to the chooser.
Is it possible to exclude apps and use directshare?
Code Snippets:
Sharing with a list of intents (How to filter specific apps for ACTION_SEND intent (and set a different text for each app)) :
final Intent chooserIntent = Intent.createChooser(targetShareIntents.remove(0), "Share with: ");
chooserIntent.putExtra(Intent.EXTRA_INITIAL_INTENTS, targetShareIntents.toArray(new Parcelable[]{}));
activity.startActivity(chooserIntent);
Sharing with directshare, but no excluding:
final Intent sendIntent = new Intent();
sendIntent.setAction(Intent.ACTION_SEND);
sendIntent.putExtra(Intent.EXTRA_TEXT, "This is my text to send.");
sendIntent.setType("text/plain");
activity.startActivity(Intent.createChooser(sendIntent, "Share with:"));

I ran into the same problem with Direct Share, and found that it only seems to work for the target intent passed to createChooser().
My kludgy work-around was to lookup "com.android.mms" and pass that intent to createChooser() and the others in the targetedShareIntents array, which means that at least Direct Share works for text messages.
Note for some apps, not setting the class name in targetedShareIntents means you end up with Android System appearing in chooser instead.
For me this solution isn't good enough, and I'm leaning towards not excluding my own app from the list. Hopefully my efforts will lead someone to something better.
Code below is a variation on examples found here:
Custom filtering of intent chooser based on installed Android package name
I see here: http://stackoverflow.com/a/23036439 that saulpower may have a better solution, but I can't get it to work with my UI.
private void shareExludingApp(Intent intent, String packageNameToExclude, String title) {
List<Intent> targetedShareIntents = new ArrayList<Intent>();
List<ResolveInfo> resInfo = getPackageManager().queryIntentActivities(intent, 0);
Intent directShare = null;
if (!resInfo.isEmpty()) {
for (ResolveInfo info : resInfo) {
Intent targetedShare = new Intent(intent);
if (!info.activityInfo.packageName.startsWith(packageNameToExclude)) {
targetedShare.setPackage(info.activityInfo.packageName);
targetedShare.setClassName(info.activityInfo.packageName,
info.activityInfo.name);
if (directShare == null && info.activityInfo.packageName.equals("com.android.mms")) {
directShare = targetedShare;
} else {
targetedShareIntents.add(targetedShare);
}
}
}
}
if (targetedShareIntents.size() > 0) {
if (directShare == null) {
directShare = targetedShareIntents.remove(0);
}
Intent chooserIntent = Intent.createChooser(directShare, title);
chooserIntent.putExtra(Intent.EXTRA_INITIAL_INTENTS,
targetedShareIntents.toArray(new Parcelable[] {}));
startActivity(chooserIntent);
}
else {
startActivity(Intent.createChooser(intent, title));
}
}
Usage:
shareExludingApp(intent, getPackageName(), "Share via");

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.

both labels shows "WeChat" when share to wechat friend and timeline

i've a android app to share message to WeChat(without sdk).
When i directly use the StartChooser method, the display-name 'Send to Moment' and 'Send to Chat' display well.
But when i want to remove the apps i donot need using a intent filter as follows, there's problem that both display-name show 'WeChat' rather than 'Send to Moment' and 'Send to Chat'.But at the same time,their icon are right!
Who can tell me how to get the right display label?? Thank you!
Intent it = new Intent(Intent.ACTION_SEND);
it.setType("image/*");
List<ResolveInfo> resInfo = getPackageManager().queryIntentActivities(it, PackageManager.COMPONENT_ENABLED_STATE_DEFAULT);
if (!resInfo.isEmpty()) {
List<Intent> targetedShareIntents = new ArrayList<Intent>();
for (ResolveInfo info : resInfo)
{
Intent targeted = new Intent(Intent.ACTION_SEND);
targeted.setType("image/*");
ActivityInfo activityInfo = info.activityInfo;
if (activityInfo.packageName.contains("tencent.mm") || etc..)
{
targeted.setClassName(activityInfo.packageName, activityInfo.name);
targeted.setPackage(activityInfo.packageName);
targeted.putExtra(Intent.EXTRA_TEXT, "share text");
targeted.setFlags(Intent.FLAG_ACTIVITY_NEW_TASK);
targetedShareIntents.add(targeted);
}
}
Intent chooserIntent = Intent.createChooser(targetedShareIntents.remove(0), "Share");
chooserIntent.putExtra(Intent.EXTRA_INITIAL_INTENTS, targetedShareIntents.toArray(new Parcelable[] {}));
startActivity(chooserIntent);
}
!!! update !!! :
if the wechat intent being placed in "Intent.createChooser", the label shown is right, but shown wrong label when placed in "EXTRA_INITIAL_INTENTS".
UPDATE2:
I find the answer at How to make an intent with multiple actions. Using LabeledIntent will solve the problem.Over.

Here is how I get it to work.
CharSequence label = info.loadLabel(getPackageManager());
Intent extraIntents = new LabeledIntent(targeted, activityInfo.packageName, label, info.icon);
targetedShareIntents.add(extraIntents);

Android image share intent - how can I exclude a particular handler from the list?

In my Android App I have an image loaded from Instragram API and I share it via the generic Share Intent like this:
Intent share = new Intent(Intent.ACTION_SEND);
share.setType("image/jpeg");
Uri uri = Uri.fromFile(file);
share.putExtra(Intent.EXTRA_STREAM,uri);
startActivity(Intent.createChooser(share, "Share Image"));
By default it gives a list of all installed apps that handle this intent, including Instagram which is the original source from where the image is coming from. How can I filter this list to exclude only the Instagram App from handling the intent while leaving all the rest?

How can I filter this list to exclude only the Instagram App from handling the intent while leaving all the rest?
You can't, except by creating your own chooser activity, using queryIntentActivities() on PackageManager and somehow filtering out Instagram. Doing that will be unreliable, simply because there are multiple possible Instagram clients, whose package names are not conclusively knowable in advance.
I'd just leave Instagram there as an option.

I used this code to filter the shareintent for instagram.
List<Intent> targets = new ArrayList<Intent>();
Intent template = new Intent(Intent.ACTION_SEND);
template.setType("text/plain");
List<ResolveInfo> candidates = this.getPackageManager().
queryIntentActivities(template, 0);
// remove all intent except instagram in share intent
for (ResolveInfo candidate : candidates) {
String packageName = candidate.activityInfo.packageName;
if (packageName.contains("instagram")) {
Intent target = new Intent(android.content.Intent.ACTION_SEND);
target.setType("text/plain");
target.putExtra(Intent.EXTRA_TEXT, "Text to share"));
target.setPackage(packageName);
targets.add(target);
}
}
Intent chooser = Intent.createChooser(targets.remove(0), translate("Share Via"));
chooser.putExtra(Intent.EXTRA_INITIAL_INTENTS, targets.toArray(new Parcelable[]{}));
startActivity(chooser);

Share multiple photos on facebook

I want in my app to share multiple photos. I am able to upload one photo using facebook graph API but how can I share multiple photos
Thanx.

Android does not provide an out-of-the-box Intent for selecting multiple images/pictures, or any other media type. Source: https://stackoverflow.com/a/12919585/450534 (And I usually will take Mark Murphy's word as Gospel unless someone can challenge it)
The closest Intent is the ACTION_SEND_MULTIPLE. That. however, is not an option for you.
You will need to create a custom selector similar to how Facebook does in it's own mobile app.
You will get a full functioning example for implementing your own multiple image selector here: http://vikaskanani.wordpress.com/2011/07/20/android-custom-image-gallery-with-checkbox-in-grid-to-select-multiple/
And finally, to upload multiple image to Facebook in one go, you will need to send Batch Requests.
But there certainly is no ready made solution for what you are looking for for. Combine all the above, and then you will. But nothing straightforward I'm afraid.

I managed to share multiple photos in Facebook using intents.
The variable "caminhos" is an ArrayList < String > with the paths of the images you want to share.
protected void share(String nameApp, String imagePath, String text) {
// TODO Auto-generated method stub
try {
List<Intent> targetedShareIntents = new ArrayList<Intent>();
Intent share = new Intent(android.content.Intent.ACTION_SEND_MULTIPLE);
share.setType("image/jpeg");
List<ResolveInfo> resInfo = getActivity().getPackageManager()
.queryIntentActivities(share, 0);
if (!resInfo.isEmpty()) {
for (ResolveInfo info : resInfo) {
Intent targetedShare = new Intent(
android.content.Intent.ACTION_SEND_MULTIPLE);
targetedShare.setType("image/png"); // put here your mime
// type
if (info.activityInfo.packageName.toLowerCase().contains(
nameApp)
|| info.activityInfo.name.toLowerCase().contains(
nameApp)) {
targetedShare.putExtra(Intent.EXTRA_SUBJECT, text);
targetedShare.putExtra(Intent.EXTRA_TEXT, text);
ArrayList<Uri> files = new ArrayList<Uri>();
for(int j= 0;j<caminhos.size();j++){
if(!caminhos.get(j).isEmpty()){
File file = new File(caminhos.get(j));
Uri uri = Uri.fromFile(file);
files.add(uri);
}
}
targetedShare.putParcelableArrayListExtra(Intent.EXTRA_STREAM,
files);
targetedShare.setPackage(info.activityInfo.packageName);
targetedShareIntents.add(targetedShare);
}
}
Intent chooserIntent = Intent.createChooser(
targetedShareIntents.remove(0), "Select app to share");
chooserIntent.putExtra(Intent.EXTRA_INITIAL_INTENTS,
targetedShareIntents.toArray(new Parcelable[] {}));
startActivity(chooserIntent);
}
} catch (Exception e) {
}
}
