Native Share for Android & iOS [Open Source]

Hi yasirkula, great asset, im using it without problem.
a doubt, now im sharing plain text in whatsapp, selecting inside whatsapp the contact/number what I want to share content.
but its possible share with a specific number without need of select it inside whatsapp?.
like the SetSubject, for emails (I not tried it yet).

 

Unfortunately not.

 

Hello, how do I share only one download link? Thanks a lot

 

new NativeShare().SetText("download link").Share();

 

Thank You yasirluka! Amazing asset!

 

Hi yasirkula, Thanks for the great asset!
I`m trying share a PDF file. And I`ve seen on this forum that it`s possible.
but this one won`t work ↓

Code (CSharp):

1.     private IEnumerator ShareFileUsingShareSheetCo(string pdfFilename)
2.     {
3.         string mLoadPath = Application.streamingAssetsPath + "/" + pdfFilename;
4. #if UNITY_IOS
5.     string filePath = mLoadPath;
6.     yield return new WaitForEndOfFrame();
7. #else
8.         string mSavePath = Application.persistentDataPath;
9.  
10.         var www = new WWW(mLoadPath);
11.         yield return www;
12.  
13.         string filePath = Path.Combine(Application.temporaryCachePath, pdfFilename);    
14.        
15.         File.WriteAllBytes(filePath, www.bytes);
16. #endif
17.         new NativeShare().AddFile(filePath).SetSubject("subject").SetText("some text").Share();
18.     }

How can I share a PDF file?
Do you have any sample code?

 

Where is the PDF file stored? In StreamingAssets folder, a subfolder or another place? Also try omitting SetSubject and SetText to see if it changes anything.

 

Thanks for the reply.
The files are placed in the StreamingAsset folder. And I omited SetSubject and SetText and tried it.



I can share the file, but the contents are empty. ;;

 

Interesting. Try using TextAssets. Simply change the file's extension to .bytes, move it outside of StreamingAssets, assign it to a public TextAsset variable and save that TextAsset to a file with textAsset.bytes. Then share that file.

 

Hi -- can the tool be used in the other direction? I have Unity as a library embedded in my native Android app, and while running the Unity player I want to load items from the native app's file system (like res or assets).

 

NativeShare doesn't have any functionality to receive files/content from outside.

 

>yasirkula It worked perfectly. Thank you.

PDF share
1.file's extension .pdf -> .bytes
2.Assign it to a public TextAsset variable
3.Run this code.↓

Code (CSharp):

1.  private IEnumerator PDFShare()
2.     {
3.         yield return new WaitForEndOfFrame();
4.  
5.         string filePath = Path.Combine(Application.temporaryCachePath, "SamplePDF.pdf");
6.         File.WriteAllBytes(filePath, _sample.bytes);　//_sample == public TextAsset _sample
7.         new NativeShare().AddFile(filePath).Share();
8.     }

 

Specifically for WhatsApp, you are able to use deep links.
Have a look here.

Hello , I appreciate it, thanks.
this is working well for me:

Code (CSharp):

1. public void SendWppToContact()
2.     {
3.         string ToWpp = "hello buddy,how are you?";  
4.         Application.OpenURL("https://api.whatsapp.com/send?phone=123456789" + "&text=" + ToWpp);
5.  
6.     }

 

Thanks for this great asset. One question here: Is it possible to also *receive* content? My use case is that the user takes a picture and then hands it over to my app. If NatShare cannot do this, are you aware of any other asset that can?

 

NativeShare can't do this. I didn't research this topic extensively, so there might be open source plugins out there; but the only plugin I saw so far is this: https://assetstore.unity.com/packag...r-android-receive-data-from-other-apps-176964

 

@yasirkula Thanks, yes, I found this asset, too. But there is no iOS version of it.

 

Sorry to hear that. I didn't search for an iOS variant so I'm unaware if one exists.

 

Hi! Just noticed that I have an error in logcat about denied permission...
Though sharing works fine. What do i miss?

 

I've googled this issue numerous times. In my opinion, it just can't be resolved. Since sharing works fine, I'd recommend you to ignore it.

 

Your asset is used in my project now to share photos: AR Masker app.

 

I do not get the full screenshot (iPhone 11) published in Instagram. Is this something that can be fixed or is it as it is?

 

Is it possible that the preview is a square but once you share the image, it is full size? If it is not the case and you are using your own screenshot function, also give the example code a try.

 

Are the java files used to build the AAR file in the repository? I don't particularly need to build the AAR file, but I like having the option. Were they removed?

 

Native source code is available at: https://github.com/yasirkula/UnityNativeShare/tree/master/.github/AAR Source (Android)

 

Hi there, thanks for the asset!

I'm just having some issues when I use the Native Share for Android and IOS with some messaging apps, like Whatsapp and Telegram. After I click to share with those aplications, I am redirected to the target app (that's fine! This is the expected behaviour!), but I noticed that the target app is “overriding” my game, in other words, I see my app's name on the title, but it´s showing the screens of the target app (like Whatsapp and Telegram). This is very confusing to the user, because he will not see my game screens anymore. It´s dificult to him to go back to my game. When the target app is Telegram, it's even more confusing because in Whatsapp the application splits in two, my game and Whatsapp, but in Telegram my game "becomes" Telegram and he needs to press "go back" button several times to return to my game . I was hoping that after the target was chosen, it would open the target app (the application splits in two) and I could go back easily to my game (by seeing my game screens when it is selected and not the target app screens).

Do you know why this is happening? Is there a way to override this behaviour?

 

Does the same thing happen when sharing from other apps to WhatsApp/Telegram? For example when sharing from WhatsApp to Telegram or from Gallery to WhatsApp.

 

No, it does not. When sharing from other apps it's spliting in two and the screen from the first app remains the same.

 

Hmm.. I really wished that the same issue occurred on other apps, too. I wonder what they do differently.

ACTION_SEND

is the standard sharing solution on Android, I don't understand why it is behaving differently in my case. I'm not aware of any way to override this behaviour.

 

Hi,
I submitted a bug where the Android device does not rotate when the Native Share dialog is open. However, iOS allows rotate.

Is this intended? Or is there something we can do?

https://github.com/yasirkula/UnityNativeShare/issues/102

 

@yasirkula this plugin support callback for Android ? How to set callback with this this function. Please have a look below which i am using.

if (NativeShare.TargetExists("com.facebook.katana"))
{
new NativeShare().SetTitle("Hello Yasir Kula").AddFile(filePath).SetText("www.google.com").AddTarget("com.facebook.katana").Share();
}

Where to set callback function for Android. please help me for this.

Thanks.

 

You can check out the SetCallback call in the example code here: https://github.com/yasirkula/UnityNativeShare#example-code

 

thanks for the great work @yasirkula . I am not sure if you have noticed that the sharing of URL link to some targets on iOS can be improved a little bit, e.g. WeChat. By setting text, there is no title and thumbnail image of the link page shared.

I played the trick with below modification to your codes, which works perfectly for my case on WeChat and has no negative effects on other targets. Just post it fyi.

Code (CSharp):

1. extern "C" void _NativeShare_Share( const char* files[], int filesCount, char* subject, const char* text )
2. {
3.     NSMutableArray *items = [NSMutableArray new];
4.  
5.     NSURL *url = nil;
6.     if( strlen( text ) > 0 )
7.     {
8.         url = [NSURL URLWithString:[NSString stringWithUTF8String:text]];
9.         if (url && url.scheme && url.host)
10.         {
11.              // this is a valid url, let's share url instead of text
12.             if( strlen( subject ) > 0 )
13.                 [items addObject:[NSString stringWithUTF8String:subject]];
14.         }
15.         else
16.         {
17.             url = nil;
18.             [items addObject:[NSString stringWithUTF8String:text]];
19.         }
20.     }
21. ...
22.    
23.     if ( url )
24.         [items addObject:url];
25.  

The best way may be adding a SetUrl() API to NativeShare, but I do not have time to investigate the Android side and this tiny modification satisfies my use case so far.

I'm now more positive about implementing this. Thanks for bringing it to my attention.

 

Hi, still support 2017.4 ?

 

5.6 and later is supported.

 

Hello. Thanks for this amazing plugin @yasirkula. May I ask you a thing? I would like to implement a reward in my game if the player shared for 5 time. I will store the variable in a playerprefs but how can I work with the method on a if statement that will check if the callback return "shared"?

I actually have the following script

Code (CSharp):

1.     public void ClickShareButton() {
2.        
3.         StartCoroutine ("TakeScreenShotAndShare");
4.     }
5.  
6.     IEnumerator TakeScreenShotAndShare()
7.     {
8.         yield return new WaitForEndOfFrame();
9.  
10.         Texture2D tx = new Texture2D (Screen.width, Screen.height, TextureFormat.RGB24, false);
11.         tx.ReadPixels (new Rect (0, 0, Screen.width, Screen.height), 0, 0);
12.         tx.Apply();
13.  
14.         string path = Path.Combine(Application.temporaryCachePath, "ImagemCompartilhada.png");
15.         File.WriteAllBytes (path, tx.EncodeToPNG());
16.  
17.         Destroy(tx);
18.  
19.         new NativeShare ()
20.             .AddFile (path)
21.             .SetSubject ("Test Subject")
22.             .SetText ("Test Text")
23.             .SetCallback((result, shareTarget) => Debug.Log("Share result: " + result + ", selected app: " + shareTarget))
24.             // do a check here if shared increase the playerprefs variable
25.             .Share ();
26.     }

Thanks.

 

You can check if SetCallback's result is not equal to

ShareResult.NotShared

(see documentation for other possible values).

 

Could you please share a simple code checking that case? I am really lost here.Thanks.

 

Code (CSharp):

1. .SetCallback((result, shareTarget) =>
2. {
3.   if( result != NativeShare.ShareResult.NotShared)
4.     blabla;
5. })

 

Hi @yasirkula thanks for the great plugin

I am just trying to share without an image, where subject and body are strings
If I select Email on iPhone the subject and text are not coming through?

Do I need to have AddFile with an empty path for it to work?

Code (CSharp):

1.         new NativeShare()
2.         .SetSubject(subject).SetText(body)
3.         .SetCallback((result, shareTarget) => DebugLog("Share result: " + result + ", selected app: " + shareTarget))
4.         .Share();

 

You don't have to. I wouldn't expect both the body and the subject to be empty. Can you verify that the parameters you've passed aren't empty? Are there any errors in Xcode console?

 

DOH
The subject wan't empty but the body was (which is another firebase dynamic link creation issue I have)
And then I was using Gmail to test which I think has a bug in iOS where the subject line is populated with the body text.
So nothing was showing as the body text was empty

So do you know how to fix this iOS Gmail bug?

Thanks for the quick response

 

I've updated the plugin on my computer to hopefully resolve the e-mail subject issue but I couldn't test it yet. I'll do so when I have access to the Mac workstation.

 

@leonliu75 Added SetUrl function with the latest update on Github, thanks!
@prawn-star The subject fix didn't work for Gmail, unfortunately.

 

Hi Yasirkula,

I have an issue trying the use both NativeGallery and NativeShare.
Context is an app for toddlers in a museum. At the end of the visit they can use the tablet to take a picture, wich will be printed at the reception using another app (DNP WPS Print).
I simply save the pic using NativeGallery.SaveImageToGallery and it works nice.
But I need to load the image back later, then print it. I load it using NativeGallery.GetImageFromGallery then use the path it returns to get the texture using NativeGallery.LoadImageAtPath and finally sharing it with

Code (CSharp):

1.                 new NativeShare().AddFile(texture)
2.                 .AddTarget(packageName)
3.                 .SetCallback(PrintShareCallback)
4.                 .Share();

However, it makes the dnp app crashs when asking the print (but accept the share at first):

If I leave the application, open the gallery and share it "manually" to the dnp wps print app, it works as intended. Am i missing something ?

Btw thanks for those awesome assets!

 

Hello Yasiruka.. Thanks for you reply. I have downloaded the latest version of your project. When i use the seturl function it just displays the url only. It does not show the thumbnail of the playstore. I am using android version.

I have doubt. In which site i can create a short link.Could you suggest any site.

I have enclosed a image( it was shared by some one). So this kind of sharing i needed?

what i can do for this...

 

@Exentro Using Android's file browser, can you navigate to Android/data/APP_BUNDLE_ID, find the image file there and share it from file browser? I'd expect the same crash to occur because looking at the error, it looks like DNP WPS Print doesn't support sharing images that aren't a part of Gallery, which is an issue on their end (I'd remind you that you aren't sharing the image in the Gallery, you are creating a copy of it by creating a Texture from it and then sharing that copy).

@Alexander21 SetUrl just appends the link to text on Android, yes. There isn't a method to specifically set url on Android. WhatsApp and other Android apps internally parse the url in the text and try to generate a preview of that url. For this to work, the target website must be able to return metadata for these previews (learn more). So the issue you are having is that, the website you are linking doesn't return this metadata.

 

@yasirkula good point Also I am impressed how fast you answered!
I tried to share the pic directly from DCIM folder and it seems their app is loading for eternity.
Trying to share using the filepath returned by NativeGallery.GetImageFromGallery instead of loading the texture makes the wps print app crashs with the same error.
Is there a way to share it from unity "as if" it came from the gallery share button ?
I will contact their support as well to ask them what _data is supposed to contains (and what columns are supposed to be provided).

 

Files in DCIM are visible in Gallery, you can't reproduce the issue with those images. Files in Android/data/APP_BUNDLE_ID, however, aren't visible in Gallery and you should be able to reproduce the issue with those.

If NativeGallery can't determine picked image's raw filepath or the filepath is restricted by Android OS, then NativeGallery copies that image's stream to a file in Android/data/APP_BUNDLE_ID. I'm guessing that this is happening in your case. This can't be avoided.

"_data" is supposed to contain the image's path if the image is in Gallery. But they don't need to know the image's raw filepath. Otherwise other apps like Facebook, Twitter, Instagram, you name it, would also crash. They must update their code to read image via ContentResolver.openInputStream to resolve the issue. They can still use "_data" if they wish, but they must fallback to openInputStream when _data fails. Crashing the app outright is just bad...
