Native Gallery for Android & iOS [Open Source]

With this Unity Asset just disable UI before start recording.

 

thank you, will try this

 

hi, i'm a beginner with unity and this is exactly the thing i was trying to find

but for some reason i can't import or use it in c#
i tried "using NativeGallary" and a few other ideas but none worked

it seems like there is just something i'm missing

what am i supposed to "using"

 

You don't need any

using

lines. Just call NativeGallery functions from your scripts. Check out the example code to learn more.

 

thank you so much!

 

Hi yasirkua! Thank you for the great assets.
I am in trouble.
I have a following error in Logcat when NativeGallery.SaveImageToGallery() is executed on Android.
Could you help me ?

Hello, we are having an issue with Xcode.

We built and tested our game for android successfully using this plugin, but when building for iOS we ran into an error.

After building to iOS from Unity successfully, opening up Xcode, and building in Xcode, we get these 2 errors right before the end:

1. incompatible pointer types assigning to 'id<UINavigationControllerDelegate,UIImagePickerControllerDelegate> _Nullable' from 'Class' imagePicker.delegate = self;
2. incompatible pointer types assigning to 'id<UIPopoverControllerDelegate> _Nullable' from 'Class' popup.delegate = self;

Is there something I need to do on the unity side or the Xcode side?

Also uploaded a screenshot below.

 

Updating the plugin to the latest version should resolve the issue.

 

We built it with version 1.6.2 when the errors popped up for us.

 

But the native code isn't the same. I'd recommend you to delete the plugin and reimport it.

 

We were able to fix the issue by removing the plugin and re-importing the plugin from your GitHub. We have be importing the one from the Unity Asset Store which had different code from the GitHub for some reason.

But it now works using the code from GitHub, thank you.

 

I keep the Asset Store version synchronized with GitHub version. I've just downloaded the plugin from Asset Store and can verify that it is the latest version. I'm uploading my assets with Unity 2018.4, perhaps if you are using an older Unity version, you can't download those newer Native Gallery versions?

 

I see. Well, just for reference, we are currently using 2020.2.2f1 and even in the Package Manager the downloaded and imported version I have was 1.6.2. It was weird, but regardless we got it working now.

 

Please see the relevant FAQ entry.

 

Hi, is it possible to set the description of permission when I ask for it? (as a parameter of a function, not in your NCPostProcessBuild.cs)

 

I use the both Native Gallery & Native Camera.

I have "This app saves videos to your Photo Library." description in the app, but in NGPostProcessBuild.cs there is no such text in both plugins.

So how can I change it from Unity (not from Xcode)?

P.S. I got rejection from Apple. So your default texts need to be improved.

"
Guideline 5.1.1 - Legal - Privacy - Data Collection and Storage


We noticed that your app requests the user’s consent to access the photos and camera, but doesn’t sufficiently explain the use of the photos and camera in the purpose string.

To help users make informed decisions about how their data is used, all permission request alerts need to specify how your app will use the requested information.

Next Steps

Please revise the relevant purpose string in your app’s Info.plist file to specify why your app needs access to the user's photos and camera. Make sure the purpose string includes an example of how the user's data will be used.

You can modify your app's Info.plist file using the property list editor in Xcode.

Resources

- See examples of helpful, informative purpose strings.
- Review a list of relevant property list keys.
"

 

But as you said, "This app saves videos to your Photo Library." string (the string that caused the rejection) doesn't come from NativeGallery or NativeCamera. You can search that string in entire project via CTRL+Shift+F in Visual Studio, another plugin might be adding that string.

I don't know if we can change Info.plist strings at runtime (passing the description as a parameter to a function).

 

Awesome. Thank you. The string was set by Cross Platform Replay Kit.

2 things caused the rejection. 2nd (Native Camera) is: "The app requires access to the camera to take pictures or record videos with it.";

 

It may not be possible to find a better description for NativeCamera that isn't app-specific (i.e. generic enough that it applies to every NativeCamera-integrated app's camera usage).

Also I think that only a portion of app reviewers reject this description because I haven't heard about app rejections in a long while. Customizing the camera usage description is of course a great thing but if you are lucky, your app reviewer won't be bothered with the generic description.

 

Hi yasirkua! Thank you for creating this asset.

I have a problem with permission request. Why does it request permission in the app start?
I want to move the permission request to the actual upload. But whatever I do it asks for the permission in the beginning

thanks in advance

 

Please see: https://github.com/yasirkula/UnityNativeGallery/issues/113

 

Approved Descriptions are next (based on Apple examples):

Privacy - Photo Library

Enable AR Masker to access your camera roll to upload your Photos and save ones you've taken with the app.

Privacy — Camera Usage

Enable AR Masker to access your camera to Take Photos and Record Videos when you are making creative content with the app.

 

Thanks for sharing, these are useful references.

 

Thank you Yasirkula, It worked for me.

 

Hey, thank you for the great asset.

I have 2 questions, if you don't mind.

1. How do I allow 2 image types when using GetImageFromGallery, for example png and jpg. The documentation only shows either all or a single image type.

2. Is it possible to find out what image type I got from GetImageFromGallery?

Thanks.

 

1. You can either allow 1 image type or all image types (leaving mime argument as is). I'd recommend you to allow all image types because LoadImageAtPath should be able to load all of them.
2. You need to check the returned image's file extension.

 

Hi yasirkua! Thank you for creating this asset.

Can you explain what is happening?

 

Yas, is there a way to limit video record time? I want to be able to only allow the use to record 30s videos. Once the 30 second hits stop the video recording. Is this possible? I figured it would be something to do with the frame callback?

 

Is this about NativeCamera or NativeGallery? NativeCamera.RecordVideo has a maxDuration parameter but you need to check out its documentation first: https://github.com/yasirkula/UnityNativeCamera#a-accessing-camera

 

Yes that's what I was looking for. Native cam. Just realized I posted this in native gallery. My bad yas.

 

I'm working from your example code, trying to take a screenshot. I'm calling the Take Screenshot and Save Coroutine from a public void attached to a UI button. When I build to my android device and press the button it doesn't save the screenshot. I have the Write Permission set to external in the project settings. I've looked everywhere on the device that an image could be stored and I can't find it. Is Native Gallery setup to work as soon as it's imported or have I missed a setup step?

 

You haven't missed a step. I'd recommend you to first check out FAQ in the main post. If it doesn't help, you should see if there are any error messages in logcat.

 

These errors spawned in logcat when I pressed the button to screenshot.

I can't see anything in the FAQ relating to those errors.

 

Quoting from the FAQ

 

Apologies. I thought ProGuard was something I would have had to add to the project, I didn't know it was a built in feature. Thanks for your patience, I'll give that a go.

 

Thanks for your help yesterday. I added that to the proguard filters but I'm still encountering the same errors. I must have missed something in setting up the proguard filters. Is there more to it than adding that filter to the text file?

 

There isn't. You just enable Custom ProGuard File and add the line to the file. Make sure that Minification in Player Settings is set to either None or ProGuard and not Gradle.

 

I've double checked all of that and tried building with the Minification set to None and then to ProGuard. I'm still getting the same errors when I try to take a Screenshot.

 

I'm sorry to hear that. Unity must be somehow ignoring your custom ProGuard filters then. I haven't heard about this issue before but I'd recommend you to google it and see if it can possibly be the case. You can also test the plugin on a new Unity project and figure out which other plugin or Player Settings might be causing this issue via trial & error.

 

Thanks, I'll give that a go

 

@yasirkula , is there a way to limit orientation? Like when recording a video can i limit the camera orientation to portrait only?

 

Unfortunately not. NativeCamera doesn't implement its own camera functionality, it invokes external camera apps. There isn't a way to customize these apps' behaviour most of the time.

 

Am I correct in thinking the LoadImageAtPath function won't apply exif rotation in the editor, but will on mobile platforms? or is exif orientation not supported

 

Exif orientation will be applied on mobile but not on the Editor, you are correct. There is no way to fetch rotation info from image without using 3rd party dependencies on Editor and I didn't really bother with that since the asset is designed for Android & iOS only.

 

Hi, I am running into a problem where nothing happens when I request to load an image, when i test it in the editor, i get a proper way to load an image but in the android player, nothing happens. Storage permissions granted

 

Please check logcat logs and see if there are any error messages there. I'm guessing that ProGuard is enabled in your project in which case you should check out the related entry in FAQ (main post).

 

Hi, where can i find the logcat logs?

 

And also, if the project does indeed uses ProGuard, where should i include this:
-keep class com.yasirkula.unity.* { *; }
?Thanks

 

You can use Unity's "Android Logcat" package. To add the filter, you first need to enable Custom ProGuard File in Player Settings. Then add the filter to that file.
