Native Gallery for Android & iOS [Open Source]

I have 2 sections in the native code that deliberately attempt to avoid this issue:

- https://github.com/yasirkula/UnityN.../NativeGallery/iOS/NativeGallery.mm#L756-L778
- https://github.com/yasirkula/UnityN...ativeGallery/iOS/NativeGallery.mm#L1030-L1048

I don't think the Code=7 log is related to this problem and the native code would log error messages if something were to go wrong in the above sections. I unfortunately don't know how this issue is occurring, let alone on both of your devices. The logs don't give me anything useful to debug the issue.

 

First I'd like to say thank you for making this plugin open source. From what I understood, the plugin apparently only allows to take pictures by pressing on a button but is there a way to do so without user intervention?

 

NativeGallery isn't a screen capture plugin, it is a plugin for saving media to Gallery or fetching media from Gallery. You can save media to Gallery without user intervention but they may need to accept gallery permission first. You can't pick a media from Gallery without user intervention, they must pick the media manually.

 

Hello,

Does this work in WebGL? I want to use on my web app and I need to take pictures then allow user to either save picture to gallery or share via Social media.

Thanks,
jrDev

 

It doesn't. Only Android & iOS are supported.

 

Hello! I got this message from Google a few weeks ago, is there any solution for this? I'm a little confused about what I need to do.

We've detected that your app contains the requestLegacyExternalStorage flag in the manifest file of 1 or more of your app bundles or APKs.

Developers with apps on devices running Android 11+ must use Scoped Storage to give users better access control over their device storage. To release your app on Android 11 or newer after May 5th, you must either:

1. Update your app to use more privacy friendly best practices, such as the Storage Access Framework or Media Store API
   
   
2. Update your app to declare the All files access (MANAGE_EXTERNAL_STORAGE) permission in the manifest file, and complete the All files access permission declaration in Play Console from May 5th
   
   
3. Remove the All files access permission from your app entirely
   

For apps targeting Android 11, the requestLegacyExternalStorage flag will be ignored. You must use the All files access permission to retain broad access.

Apps requesting access to the All files access permission without a permitted use will be removed from Google Play, and you won't be able to publish updates.

 

Please see: https://forum.unity.com/threads/nat...d-ios-open-source.519619/page-23#post-7041952

 

perhaps you should consider a merge with https://github.com/gkngkc/UnityStandaloneFileBrowser

that is how I handle it...

that would give basic access to window, mac, Linux, and webgl

 

At the moment, I'm happy with supporting only Android & iOS but thank you for the suggestion.

 

Hey @yasirkula
Thank you so much for this wonderful solution, saved me a lot of headaches!

While the solution works perfectly, we are now trying to list the image files by name to our users, which works perfect on Android, but on iOS the image name is "pickedMedia1"

Is there a way in which to get the correct file name on iOS? : )

Thank you in advance!
And keep up the great work mate!

 

hi! @yasirkula
It was updated to version 1.6.3
Unity : 2018.4.11f

Code (CSharp):

1. saveDir = AJC.CallStatic<string>( "GetMediaPath", Application.productName );

'GetMediaPath' Error occurred.


What should I do?
It is difficult to get information.

 

@FenrirGameStudio It requires modifying parts of the native code that use

pickedMediaSavePath

. It won't always work because in some cases, iOS returns just a UIImage so we don't have a file path to work with in those cases.

@Jo_Da GetSavePath has been removed a long time ago. You can see this thread for a discussion about it: https://github.com/yasirkula/UnityNativeGallery/issues/78#issuecomment-541333226. You can take a look at SaveImageToGallery's callback function and see if it works for you.

 

After updating to xcode last version i get this errors from nativegallery.mm


Incompatible pointer types assigning to 'NS_REFINED_FOR_SWIFT id<PHPickerViewControllerDelegate>' from 'Class'
Incompatible pointer types assigning to 'NS_REFINED_FOR_SWIFT id<PHPickerViewControllerDelegate>' from 'Class'
Incompatible pointer types assigning to 'NS_REFINED_FOR_SWIFT id<PHPickerViewControllerDelegate>' from 'Class'


Any solution to fix this?

 

Is the plugin up-to-date? Can you delete it and reimport it?

 

Thanks for letting me know! : D
I'll see what I can figure out, if I find a solution I'll get back to you : )
Cheers!

Please help me I am stuck for a while...

It work ok on telegram but on whatsapp get this:

Hey, is it possible to check the file size in MB (or set max size) of the image that I get from GetImageFromGallery?

 

You can't set a file size limit with NativeGallery, unfortunately. After the image is picked, you can check its file size via

new FileInfo(imagePath).Length

.

 

Hi there, your assets is great I already gave you 5 stars on assets store, I am having problem saving the image inside the unity game that I got from android gallery using your example code, actually i want the image to be saved inside the image gallery of game and when user closes the game or scene transitions performed those saved images remain saved inside the game. PLEASE HELPPPPPP..............!!!!!!!!!!!! It will be very helpful if you can write some example funtions for me. Thanks.

 

please help.

 

The only way to achieve this is to copy the returned image file to

Application.persistentDataPath + "/SavedImage.png"

using File.Copy and then reload it from that path via NativeGallery.LoadImageAtPath when the image is needed. But you need to make sure that the file exists at that path via File.Exists.

 

Can you help me with the code I am beginner to unity game dev. please can you write a functions for saving image using Application.persistentDataPath + "/SavedImage.png" , I shall be very very thankful to you, this is part of my exam so please help. PLEASE.

 

Sure. To save the image at path imagePath to that path:

System.IO.File.Copy(imagePath, Application.persistentDataPath + "/SavedImage.png", true);

 

Thank you so much, it really helped me out, one last question please how can I load that copied image using NativeGallery.LoadImageAtPath ???

 

Code (CSharp):

1. Texture2D texture = null;
2. if(File.Exists(Application.persistentDataPath + "/SavedImage.png"))
3.     texture = NativeGallery.LoadImageAtPath(Application.persistentDataPath + "/SavedImage.png", 1024);

 

I want to know how to check if the saved image file at persistentDataPath Exists or not?? I am using C# developing a game I tried to use IF statment like this but it doesn't work.

if(File.Exists(Application.persistentDataPath + "/MyAlreadySavedImageFile.png") == "MyAlreadySavedImageFile.png")

Need to use IF statement because I have to check a series of images to compare.

Any Suggestions??

 

if(File.Exists(Application.persistentDataPath + "/MyAlreadySavedImageFile.png"))

 

Thanks alot you are champion

 

Hey, how do I handle gifs if there is one at the path?
I assume: texture = NativeGallery.LoadImageAtPath(path, -1, false, false); wouldn't work because gif can't be loaded into a texture.

Also, I have one more question if you don't mind.
Does the downscale use Bilinear or Point?

Thanks.

 

LoadImageAtPath was able to load all OS-supported images in my tests. Gifs won't be animated, though. Downscaling is handled by OS' native implementation. I don't know which algorithm it uses but the end results have always looked smooth to me, so I don't think Point downscaling is used.

 

[The minSDk version can not be specified in the AndroidManifest.xml file. You have to remove it. I am getting this error when I build the game using unity. I am using firebase and native gallery plugin. I have two android manifest files in my project screen shoots are attached. PLEASE HELP ME.][1]

Does deleting NativeGallery resolve the error?

 

Hi, I meet some problem
The exif data from image captured by Native Gallery is missing GPS related data in iOS

I don't know it is the iOS limitation or Native Gallery...

 

Hi,
I am having this error when trying to build my project for ios. Anybody have an idea what is wrong over there. The same project works fine for android.

"
Incompatible pointer types assigning to 'id<UINavigationControllerDelegate,UIImagePickerControllerDelegate> _Nullable' from 'Class'
"

Unity version: 2019.3.3f1
Xcode: 12.5

Error image link: https://ibb.co/P9Wsp2F

 

@Leonard_InitializeGame GPS data is stripped by iOS. It may be retrievable when full Photos permission is granted but it isn't a supported use-case in NativeGallery for unrelated technical reasons.

@Nabeel-Akhtar You should delete the plugin completely and reimport the latest version.

 

@yasirkula Thank you I will be doing that and will be updating for sure.

 

Also tried that but same error. What should i do?

 

You need to ask this question on Android sub-forum. No need to mention NativeGallery there since it isn't the cause of the issue, as you said. I'd recommend you to google the error first, though:

unity minsdk version can not be specified in the AndroidManifest.xml

 

Thank you for your reply

 

Hey @yasirkula

I have an app freeze on iOS 14.6 when choosing "Select photos".
I found that line 223 won't be called in this case:


"Permission free mode" is not an option for me.

Could you help, please?

 

With the current synchronous permission system, it is impossible to resolve the freeze when "Select photos" is clicked. You need to either don't modify permission free mode (why would you do this anyways) or heavily modify both NativeGallery.mm and NativeGallery.cs so that permissions are asked asynchronously. It'll be a tedious task so I can't help with that :/

 

I have this exact same problem. Removing the asset and reinstalling it doesn't fix it. Can I just comment that line or there is some other way to fix it?
Unity Version: 2020.1.4f.
XCode: 12.5

 

You can change the line to

imagePicker.delegate = (id) self;

but it should already be like that in the latest version. I don't understand why Unity struggles to import the latest version from Asset Store on some users' projects.?!..

 

thanks, it temporary solved the problem (if I rebuild I need to remember to change this line)

 

You can change the line inside Unity. There's NativeGallery.mm there, too.

 

Hi Yasirkula,

I would like to ask permission to the user to view the users gallery in order to pick a picture. I played with the objective C nativegallery.mm because i see it automaticaly gives permission if > ios 11. I want all iOS's to ask for permission. So after I changed the setting from 1 to 2 it did nothing. I notice in debug.log the permission status is indeed changed to ask for permission. However no message ever pops up asking for it. So i'm unsure how to proceed. Hopefully I don't have to write a message plugin, but I was considering that. Do you have any thoughts?

 

You need to remove only this part but I highly recommend you to NOT do that. NativeGallery asks permissions synchronously but iOS 14+'s "Select Photos" option in permission dialog doesn't support it and causes the app to freeze indefinitely when clicked.

 

Hi Yasirkulla,
That is exactly the bug I ran into. And it DID freeze indefinitely. I'm wondering how I can get it to pop up a message asking for permission instead of freezing. Any ideas?

"iOS 14+'s "Select Photos" option in permission dialog doesn't support it"... what does this mean? Are you saying that when the permission changes from "granted" to "ask for permission" that iOS 14+ doesn't know how to ask?

 

Select Photos doesn't support synchronously selecting photos, it freezes indefinitely. Are you attempting to show a permission popup and just ignore its result? You want to ask the permission just for the sake of showing the permission dialog and don't care which option the user has picked? Why?

 

To be clear, here is what I want:
When the user clicks on the "add a photo" button, a dialogue pops up asking for permission to view the photo gallery. If the user selects "yes", then the gallery pops up and we do the thing. In the future, no dialogue pops up for this user agian. If the user selects "no", the gallery does not pop up, we don't do the thing. In the future, a diologue pops up saying you need to give access in settings for this app to view the gallery.

What do you mean "select photos doesn't support synchronously selecting photos"? Do you mean that it supports asynchronously selecting photos? And as such you cannot ask for and grant permissions?

I understand that the method GetImageFromGallery is asynchronous. Before that I am using the method RequestPermission and it doesn't do the popup dialogue.

Is it now clear what I'm attempting to do? (btw thanks for this awesome free plugin, I want to preface that before we go any further)
