sending link with preview using sharesheet

I'm trying to do the following in my application:
Basically, my goal is that users will be able to share my app with their friends( for this example I used google link).
I tried to do the following but it didn't work:
Intent sendIntent = new Intent();
sendIntent.setAction(Intent.ACTION_SEND);
sendIntent.putExtra(Intent.EXTRA_TEXT, "I really liked the app! you should try it too =) \n\n" + getResources().getString( R.string.ActivityProfile_ShareMessage ));
sendIntent.setType("text/plain");
Intent shareIntent = Intent.createChooser(sendIntent, null);
startActivity(shareIntent);
Where
<string name="ActivityProfile_ShareMessage">![CDATA[via Download the app from the Play Store]]</string>
But it just gave me a text and not a link and without any preview like shown in the image.
Any way to do it?
Also, I saw that there are solutions that work either for email or WhatsApp. Isn't there a solution for both? For example, text/html won't work for messages and so on.
Thank you

Send string by an intent to any other apps

I'm trying to send and intent which contains a String. I want to share this intent implicitly, so I don't want to specify the app who will receive this Intent.
Let me explain, the string I want to send will be send thank's to the Intent, and in the same app put in the clipboard, and then I paste the clipboard thank's to AccessibilityService in another app.
The intent will serve to be catches first by the clipboard, and then by another app (with a script code to this intent, because the app is too already created but can't be edited.
So I started to do this :
Intent intent = new Intent();
intent.putExtra(Intent.EXTRA_TEXT, "This is my text to send.");
intent.setType("text/plain");
intent.addFlags(Intent.FLAG_ACTIVITY_NEW_TASK);
startActivity(intent);
from the developer.android site, but it open a menu in which I must chose an app to share the intent, that's what I won't.
Could you help be?
NOTE: I'm French, sorry for my poor English

Android: How can I take a screenshot of the current activity and share it?

I should be able to press a button that takes a screenshot of the current activity (without showing the Toast message on the display) and then opens the dialog to share it on social networks or various apps. I hope you got what I need to do and you can help me.

How to take a screenshot programatically
After that, you can send a share intent with the screen shot image uri attached.
Like so:
Intent shareIntent = new Intent();
shareIntent.setAction(Intent.ACTION_SEND);
shareIntent.putExtra(Intent.EXTRA_STREAM, uriToImage);
shareIntent.setType("image/jpeg");
startActivity(Intent.createChooser(shareIntent, getResources().getText(R.string.send_to)));

Remove Contact select option form file select options

I am opening file pick Intent with, Bellow code
Intent intent_upload = new Intent();
intent_upload.setType("*/*");
intent_upload.setAction(Intent.ACTION_GET_CONTENT);
activity.startActivityForResult(intent_upload, Constants.FILE_PICK_REQUEST_CODE);
I Want remove Contact option from list, please can anyone help.
Thanks

Use below code I think it can help you and also refers Link
Intent intent_upload = new Intent();
intent_upload.setType("*/*");
intent_upload.setAction(Intent.ACTION_GET_CONTENT);
intent_upload.addCategory(Intent.CATEGORY_OPENABLE);
activity.startActivityForResult(intent_upload, Constants.FILE_PICK_REQUEST_CODE);

You need to specify what type of intent (apps) you want to open. Now you set offer me all apps:
intent_upload.setType("*/*");
This can be different type for images, music, documents etc. eg.:
intent.setType("image/*");

As CommonsWare said you don't have alternatives than setting the specific MIME_TYPES and ignore using "*/*". Use specified MIME_TYPES like here..
String[] mimetypes = {"image/*", "video/*"};
Intent intent_upload = new Intent();
intent_upload.setType("image/*,video/*");
intent_upload.putExtra(Intent.EXTRA_MIME_TYPES, mimetypes);
intent_upload.setAction(Intent.ACTION_GET_CONTENT);
MainActivity.this.startActivityForResult(intent_upload, Constants.FILE_PICK_REQUEST_CODE);

Debugging Intents

I asked a question previously about what shows up in the IntentChooser when I send an Intent with ACTION_SEND and MIME type "image/png". The problem is that some phones come with a default messaging app that is not showing up in the list, mine included (myTouch 4G) as well as a user that I speak with over email (using an HTC EVO). If I choose a Send or Share option from the built in gallery app or another application on the same image I'm saving and attempting to send directly from my app, Messages shows up in the list. From my app it does not. Other phones don't have this problem, so it's clearly a platform specific thing. But that doesn't mean I should just ignore the problem.
So, I go to troubleshooting the issue. I register one of the activities in my app to receive the the same type of intent, and then hit a breakpoint to analyze the Intent object being sent from the two different ways of sending it.
The problem is, the intent I'm sending and the intent being sent from Gallery or AndroZip (where Messages does show up in the chooser) seem to be the same. They both have the same action, same categories, same flags, same mime type. What else can I inspect on the Intent from Gallery or AndroZip to tell if there's some more information I can add to my Intent to get the default messaging app to show up in the chooser in cases where it is not?

The problem is specific to HTC Sense phones, and it arises because their Gallery and Messaging apps are different to the stock ones.
Specifically the Intent sent from Gallery to Messaging has the action android.intent.action.SEND_MSG which is different to android.intent.action.SEND. The Sense messaging app doesn't handle SEND, unlike the stock messaging app.
So the question becomes, how is the Sense Gallery app creating an activity chooser dialog which combines both SEND and SEND_MSG ?
I've done some research and got mostway there... the code below works, but the "Messages" entry in the dialog appears at the top rather than in alphabetical order as per Gallery. Doubtless some more research into intents would correct that, but at least this works:
// Create a chooser for things that can ACTION_SEND images
Intent intent = new Intent(Intent.ACTION_SEND);
Uri data = Uri.parse("content://media/external/images/media/98");
intent.putExtra(Intent.EXTRA_STREAM, data);
intent.setType("image/jpeg");
Intent chooser = Intent.createChooser(intent, "Blah");
// Add the stupid HTC-Sense-specific secondary intent
Intent htcIntent = new Intent("android.intent.action.SEND_MSG");
htcIntent.putExtra(Intent.EXTRA_STREAM, data);
htcIntent.setType("image/jpeg");
chooser.putExtra(Intent.EXTRA_INITIAL_INTENTS, new Intent[] { htcIntent });
// Show the chooser
startActivity(chooser);

First of all, +1 to Reuben, he is the genius, not me. But I had to modify his code a bit to get it to work. Basically I had to putExtra() on the htcIntent or the image never got stuck to the Intent.
Tested and validated on a Droid X and HTC Incredible (which had the same problem until now thanks to Reuben).
Uri uri = Uri.fromFile(new File(mFile));
Intent intent = new Intent(Intent.ACTION_SEND);
intent.putExtra(Intent.EXTRA_STREAM, uri);
intent.setType("image/png");
Intent htcIntent = new Intent("android.intent.action.SEND_MSG");
htcIntent.setType("image/png");
htcIntent.putExtra(Intent.EXTRA_STREAM, uri);
Intent chooser = Intent.createChooser(intent, "Send Method");
chooser.putExtra(Intent.EXTRA_INITIAL_INTENTS, new Intent[] { htcIntent });
startActivity(chooser);
Edit: I realize I'm putting the image on two Intents now, but I couldn't get it to work any other way.

Instead of debugging the intents, why not try to compare how your starting the chooser with how the gallery is doing it. It is open source after all, so instead of trying to guess at the issue with the result, you can debug from the cause.
