I have implemented sharing feature using Intents and it's working properly. I'm sharing a bitmap by converting it to a file. But I want to add an extra caption along with the post when users share it. I tried this:
Intent share = new Intent(android.content.Intent.ACTION_SEND);
share.setType("image/*");
share.putExtra(Intent.EXTRA_TEXT, " Shared via App"); //this part doesnt work
share.putExtra(Intent.EXTRA_STREAM, Uri.parse("file://" + sharefile));
//sharefile is my image file. It gets shared properly.
try {
startActivity(Intent.createChooser(share, "Share Product"));
} catch (Exception e) {
}
But it doesn't share the CAPTION. It shares the Image successfully.
Try Intent.ACTION_SEND_MULTIPLE instead Intent.ACTION_SEND
Other applications determine whether or not they support attaching a caption to an image or not. If you are experiencing issues with a specific platform ignoring the Intent.EXTRA_TEXT that you pass with the image, you will need to contact the developers of that application for support.
Facebook is one example of a platform that does not support attaching a caption or description to an image. Here's a bug report requesting this feature with the response from the Facebook team. In this case, attaching a message would violate Facebook's platform policies.
Just add this line:
intent.putExtra(Intent.EXTRA_TEXT, caption);

Intent sendIntent = new Intent("android.intent.action.MAIN");
sendIntent.setAction(Intent.ACTION_SEND);
sendIntent.setType("text/plain");
sendIntent.putExtra(Intent.EXTRA_TEXT, videoLink);
sendIntent.setPackage("com.whatsapp");
startActivity(sendIntent);
I can send the link containing the video to someone on WhatsApp, however, I want to show the image of the video to the user on WhatsApp.
Is there a way to do this in java or kotlin
as in the picture
I am not sure what you're trying to do exactly but there are two options I can think of.
Firstly, if you're looking for something like what you have in the screenshot then no coding is required.
This is usually handled by Facebook when their bot scrapes the meta tags from the page that is shared.
If you wanted to accelerate this process you can manually put the link that you want to share in Facebook's Sharing Debugger and scrape it manually so that Facebook takes note of it.
Once that is done you can share the link and it should display video information including the image, title & description.
However, if you want to share only the video image/thumbnail you can do that as follows:
grab the video ID from the URL using REGEX or by taking a substring of the URL that holds the ID.
Plug that ID in one of the following URLs to get a link to an image that you can share instead of the video.

Is there a built-in way for a grid bottom sheet, usually seen for sharing in some apps, or do I have to create a custom BottomSheet?
//1 column bottom sheet
String message = "Text I want to share.";
Intent share = new Intent(Intent.ACTION_SEND);
share.setType("text/plain");
share.putExtra(Intent.EXTRA_TEXT, message);
startActivity(Intent.createChooser(share, "Share through:"));
The intent chooser is a property of the OS and you can't really change it. As you might have noticed, this chooser has changed its appearance in the different releases of the OS. The apps in which you have seen a grid chooser might have implemented a custom bottom sheet or activity to look like a bottom sheet. You can achieve this by using the Android PackageManager. You can obtain the different apps that can handle your intent and show these in your custom chooser and then send the intent to the app which the user clicks on.
I had an interview today for a junior android dev position and one of the questions I was asked was something like this:
You have an application that opens an email. The email has a photo attached to it. How could you give the user the choice of which application to open this photo with? I.e. give them a list of photo opening apps to choose from and then open that application with the photo. You don't know ahead of time what apps are available other than android's default photo viewer.
How the heck do you solve this?
Intent intent = new Intent();
intent.setAction(android.content.Intent.ACTION_VIEW);
File file = new File("/sdcard/foo.jpg");
intent.setDataAndType(Uri.fromFile(file), "image/*");
startActivity(intent);
In a nutshell, you are telling Android, in an abstract way that you'd like to view a photo. Apps that are able to view photos register their ability to do so in their manifest (they respond to ACTION_VIEW, for the given content type image/*).
If you wanted to view an HTML file,
intent.setDataAndType(Uri.parse("http://www.google.com", "text/html");
ACTION_VIEW is just one example. There's also an ACTION_EDIT, and others.
I need some advice for this matter...
I used the facebook android sdk to create an integration with facebook from my application...I followed this tutorial:
http://www.integratingstuff.com/2010/10/14/integrating-facebook-into-an-android-application/
I would need to implement authentication in one activity and the function postToWall in another.... after authentication i want to send post simply by pressing a button but in other activity, different from that where i do authentication.
is it possible? or with the SDK I'm forced to do everything together in the same activity?
thanks in advance
Yes it is possible. You will get a access token which you can send to the next activity. Use getAccessToken() and setAccessToken().
Here is an example that even saves the needed data: Contact-Picture-Sync
you need to install an extension, similar to the core Android SDK, but no, here is what you need to do:
1.) go to github.com/facebook/facebook-android-sdk
2.) download the facebook directory ONLY! The other directories are only examples.
3.) Put the files from the src (you can copy the drawables too, if you want to) in the package, you are currently working with
4.) You are good to go, you can use the facebook "SDK"
see also this example https://github.com/facebook/facebook-android-sdk/tree/master/examples/Hackbook download it , it is working example provided by facebook
just to provide an alternative answer, there's other ways of implementing sharing on Android.
It allows for more sharing options (like Twitter, QR-Barcodes, blogging and whatnot) without having to deal with the facebook android sdk.
What you would use is a "share" intent, like so:
String title = "My thing"; // used if you share through email or channels that require a headline for the content, always include this or some apps might not parse the content right
String wallPost = "Hey - check out this stuff: http://link.com "; // the content of your wallpost
String shareVia = "Share this stuff via"; // the headline for your chooser, where the phones avaliable sharing mechanisms are offered.
Intent shareIntent = new Intent(android.content.Intent.ACTION_SEND);
shareIntent.setFlags(Intent.FLAG_ACTIVITY_NEW_TASK);
shareIntent.setType("text/plain");
shareIntent.putExtra(android.content.Intent.EXTRA_SUBJECT, title);
shareIntent.putExtra(android.content.Intent.EXTRA_TEXT, wallPost);
startActivity(Intent.createChooser(shareIntent, shareVia));
This is by far the preferred solution on Android if you're looking for simple sharing, as it makes your app future-compatible with new services. And more lean and flexible for the user too, as there's little to no friction from hitting the share button to posting content.
It can also be seen in this blog post: http://android-developers.blogspot.com/2012/02/share-with-intents.html
I hope you can use this for your project.
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.
