Native Share for Android & iOS [Open Source]

Thanks for the great Plugin. I had this all working nicely on Android and iOS, however, suddenly I got an issue on iOS. I'm on a iPhone X with latest iOS 13.x.
The first time I call NativeShare in my app it works as expected. Subsequent times, the Native Share panel comes up, but is empty, no sharing options just a blank grey panel. Works again only if I quit the app and restart the phone.

I'm not using anything fancy just:
new NativeShare().AddFile(pathAndFilename).SetSubject("subject blah blah").SetText("").SetCallback((result, shareTarget) => Debug.Log("Share result: " + result + ", selected app: " + shareTarget)).Share();

Any idea?

 

Does omitting SetSubject and SetText change anything? Are there any error messages in Xcode console?

 

@yasirkula Does this asset support WebGL? I believe it could support it using Navigator.share() api.

 

I'd like to stick with Android & iOS platforms only but thank you for the suggestion!

 

cries in jslib plugin

 

new NativeShare().AddFile(filePath).Share();
I'm using this to share image / video. There's multiple issues I'm having on iOS.
- I'm unable to share video on some devices
- On some devices some apps don't even show up in the list of applications

Am I missing something?

 

Your code looks OK. I'm assuming that it doesn't contain SetText or SetSubject functions. I'd recommend you to check out Xcode logs for anything suspicious.

 

Yes! It doesn't contain SetText or SetSubject functions.

This is on iPhone X and on some iPads...iPhone 11 & iPhone 7 worked. The only difference is the iPhone X is on iOS 12...but I've heard from other users that they were on iOS 13 and still wasn't working.

Error log with the call back:

I wonder if sharing from other apps to Instagram also yield the same error. Because there is a slim chance that it is an iOS bug. Otherwise, perhaps the mp4 file wasn't completely written to the disk (i.e. the file stream was still open) while sharing it. You can try waiting a few seconds in a coroutine before sharing the file to see if it makes any difference.

 

Hello @yasirkula,

First off, thanks for the plugin.

I have a weird issue with it, though, was wondering if it's been documented already. When taking a screenshot (via ReadPixels or CaptureScreenshotAsTexture, after waiting for end of frame) and sharing it, iPhone XS returns it with a white semi-transparent filter over it, causing the image to look very bleak, while an iPad Air 2 running the same version of iOS (13.7) shares a crystal clear image. Any idea what might be causing it?

 

I haven't heard about this issue before. Can you create a Texture from the screenshot using Texture2D.LoadImage and display it in a RawImage to see if the screenshot itself has this issue?

 

Can I ask you to elaborate a bit on what you're asking to do? LoadImage (from what I understand it's under ImageConversion now) takes a texture (that of a RawImage component, in our case) and fills it with some byte data. How do I turn a screenshot into a byte array? I'm quite new to this, the only way I'm aware of is via some sort of serialization, like with a BinaryFormatter.

 

You already have a screenshot that you are passing to NativeShare. You'll just need to call File.ReadAllBytes on that path and pass those bytes to LoadImage.

 

I'm sharing it long after It's saved.

 

NativeShare seems to work great! I do have an issue when sharing a video to slack on iOS. It does share successfully, but then the native share overlay never seems to close after it shares. The app just looks like it hangs.

My share call is simple enough.

new NativeShare().AddFile(videoFileName).Share();

 

@Suwas93 Does sharing from e.g. WhatsApp to Instagram or Photos to Instagram also yield the same error?

@DryHeat I've heard that this is Slack app's behaviour and sharing media from other apps to Slack also suffer from the same issue.

 

Tried it, and the screenshot itself has this pale overlay, so it's not related to Native Share. If you have any ideas why it could be happening on an iPhone and not on an iPad, I'd appreciate any help.

 

The example screenshot code has been working fine for me. If it also has the same issue, I unfortunately don't know why this issue is occurring. Probably a post-processing effect is causing the issue.

 

Yeah, that's the one I've been using to take screenshots. Still, thanks for the feedback.

 

Wanna ask are these permissions required for saving/sharing pictures?

READ_EXTERNAL_STORAGE
WRITE_EXTERNAL_STORAGE

 

They aren't needed.

 

Thanks!

 

Thanks for the great plugin!

I went through the problem with either text or image and went for image.
For me, setting the file and subject worked perfectly.
(I'm not setting the text in general or title for Android)

Code (CSharp):

1.         // Set content
2.         shareObj.AddFile(pathName);
3.         shareObj.SetSubject(shareText);
4.  
5.         shareObj.Share();
6.  

However on one Android test device, WhatsApp says can't send emtpy messages.
Once I enter a text, it works, but the image is discarded as already known.

Tried with shareObj.SetText(""); but that didn't work.

Most test devices don't have that issue.
Any advice? Have you come across this before?

 

I don't think I have. Perhaps WhatsApp isn't up-to-date on that device?

P.S. Does omitting subject help?

 

Without subject leads to the same result

It’s the latest version from Google Play. However it was updated manually to the last version, but with same result...

 

As much as I want to help, I don't know what is causing this issue on that particular Android device or how it can be resolved :/

 

Hello YasirKula, your plugin is fantastic, I have implemented that in android and working perfectly, now I have to do in ios. So can you please tell me how to share my text and image to a specific app like whatsapp,facebook,insta. as i have prebuilt buttons for each platforms. Thank you

 

Please see the relevant FAQ entry here. I'd also recommend you to take a look at the "I can't share image with text on X app" FAQ entry, just in case.

 

Hello Yasirkula, thank you for your reply, I need to make my question clear.
I don't have problem with sharing only image. What I need is to be able to share to a specific app as i made buttons for each app. like using addTarget() in android, it's not working for ios please give some guidance on that.I have searched a lot on internet and end up on getting only android tutorials. Thank you for your time

 

I was trying to point you to this FAQ entry ^^:

• Can I share on a specific app?

On Android, you can share on a specific app via AddTarget. For iOS, you can check out this post and see if it works for you: https://forum.unity.com/threads/native-share-for-android-ios-open-source.519865/page-4#post-4011874
​

In your case, though, you must pass an int parameter to native code to determine the target app and then set excludedActivityTypes accordingly.

 

sorry for asking lot of doubts... i dont really know the working of the nativeshare.mm so where should i pass the int values

 

You should inspect lines 46 and 188 here, and line 9 here.

 

Hello Yasirkula, thank you very much for for creating and making Native available. I have a question: as I understand it, one can share text and images inside a unity app to all apps that support sharing. Is it possible vice versa? E.g. can one make a unity app appear in the Share panel when say I want to share a YouTube link?

 

You can't do it with NativeShare but with other plugins like this.

 

Hi Yasirkula,

Thanks for this plugin.

Is there a way to display the captured screenshot into an UI image, please? Sorry for this noob question. I'm very new to this.

You said: "You'll just need to call File.ReadAllBytes on that path and pass those bytes to LoadImage."

Code (CSharp):

1. File.ReadAllBytes(imagePath);

I don't understand this part: pass those bytes to LoadImage.

Can you post an example please?

My goal is to display the captured screenshot in an UI image with a share button under the image.

Thanks in advance!

Kind Regards,
John

 

You can call these TakeScreenshot and ShareButtonClicked functions:

Code (CSharp):

1. public Image imageObject;
2. private Texture2D screenshot;
3.  
4. public void TakeScreenshot()
5. {
6.     StartCoroutine( TakeScreenshotCoroutine() );
7. }
8.  
9. private IEnumerator TakeScreenshotCoroutine()
10. {
11.     yield return new WaitForEndOfFrame();
12.  
13.     // Destroy previous screenshot (if any)
14.     Destroy( screenshot );
15.    
16.     screenshot = new Texture2D( Screen.width, Screen.height, TextureFormat.RGB24, false );
17.     screenshot.ReadPixels( new Rect( 0, 0, Screen.width, Screen.height ), 0, 0 );
18.     screenshot.Apply();
19.    
20.     Sprite sprite = Sprite.Create( screenshot, new Rect( 0f, 0f, screenshot.width, screenshot.height ), new Vector2( 0.5f, 0.5f ), 100f );
21.    
22.     // Assign sprite to Image
23.     imageObject.sprite = sprite;
24. }
25.  
26. public void ShareButtonClicked()
27. {
28.     string filePath = Path.Combine( Application.temporaryCachePath, "Screenshot.png" );
29.     File.WriteAllBytes( filePath, screenshot.EncodeToPNG() );
30.  
31.     new NativeShare().AddFile( filePath ).Share();
32. }

 

AMAZING!!!
Thank you very much Yasirkula! You're awesome!

I've tested the script in a build on my android device and it works very nice!

 

Awesome, thanks for the tip!

 

I'm having trouble sharing to instagram on iOS. I'm using the screenshot example above that you provided. It works fine when sharing to the other platforms, but I get these errors when trying instagram. I know it was working in the past, but I believe it may have stopped working after upgrading to Unity 2020. Is anyone else using Unity 2020?

I couldn't find any useful results on Google and couldn't figure out the possible cause of this issue by looking at the error messages. Unfortunately, I don't have access to my Mac workstation for a while either, so it will take some time to reproduce the issue. In the meantime, I'd recommend you to create an Issue on GitHub: https://github.com/yasirkula/UnityN...ees=&labels=bug&template=bug_report.md&title=

 

hey @yasirkula have worked with your plugin in the past. works well. wondering now if your plugin works in a webGL build. recently ran into issues using the native html way of navigator.share().

 

Only Android and iOS platforms are supported.

 

I have an app where i have deep linking enabled, is it posible to send a link it to whatsapp so that when the user clicks on the link the app opens?

 

I think so. Did you try passing the link to SetText function?

 

Social sharing not working (Unity 2020.1.9f1 - Linux) only after compiling as Build App Bundle (Google Play ..)..?
Subsequent .apk won't work, note base.apk not available in non-bundle compilation, but search path..

Caused by: java.lang.ClassNotFoundException: Didn't find class "com.yasirkula.unity.NativeShare" on path: DexPathList[[zip file "/data/app/com.Gabgames.Knhop-SZeGgijYmB2w9_kt4VE-pg==/base.apk"],nativeLibraryDirectories=[/data/app/com.Gabgames.Knhop-SZeGgijYmB2w9_kt4VE-pg==/lib/arm, /data/app/com.Gabgames.Knhop-SZeGgijYmB2w9_kt4VE-pg==/base.apk!/lib/armeabi-v7a, /system/lib, /system/vendor/lib]]

 

Is ProGuard or Gradle minification enabled? If ProGuard is enabled, see the relevant entry in FAQ.

 

I had the exact same problem. It seems related to a memory leak, when I try to share a screenshot for print with this: ScreenCapture.CaptureScreenshotAsTexture(4)

The strange thing is that if I save the image in the camera roll, then I can share it without problem. Can it be that the plugin put a limit to the image size?

I encounter that problem with a new clean project using Unity 2020.1.14, xCode 12.2 macOs Big Sur, and iPhone X.

 

I didn't put an image size limit. Can I see your code that saves the image to camera roll and then shares it?

P.S. Oh, did you mean saving to Photos via NativeGallery, opening Photos app and then sharing the image from there?

 

Hi is there a way to save directly to the camera roll rather than via the native share popup?

 

Yes, you can use NativeGallery: https://assetstore.unity.com/packages/tools/integration/native-gallery-for-android-ios-112630
