Parameter "imagePath" is null or empty

[KornyAS]

Hello, I have a problem with getting picture from gallery, it returns me "Parameter imagePath is null or empty" when I select any of the pictures. Permissions are granted.

Reproduction steps Loaded from assetstore and use the plugin as ` NativeGallery.Permission permission = NativeGallery.GetImageFromGallery((path) => { print(path); Texture2D texture = NativeGallery.LoadImageAtPath(path); if (texture == null) { Debug.Log("Couldn't load texture from " + path); return; }

            BlitBlurShader.instance.EnableBlurFade(gameObject);
            contentMain.GetComponent<RawImage>().texture = texture;
            contentRender.GetComponent<RawImage>().texture = texture;
        }, "Select an image");
        print(permission);

`

• Unity version: 2020.2.1f1
• Platform: Android
• Device: Redmi note 10 pro
• How did you download the plugin: Asset Store

Thank you for the detailed bug report. Can you reproduce this issue on any other device model (preferably not another Redmi)?

[KornyAS]

Hello, I tested on a samsung galaxy S9+ and it works correctly. But whats's wrong with my redmi? How to fix it?

[yasirkula]

I wonder that, as well 😞 Unfortunately, I have no idea why your device doesn't receive the image's path. Are there any useful logs in logcat?

Here are my logs

Here, it's the same but more comfortable view

[yasirkula]

Unfortunately, there aren't any suspicious logs here. At the following native line, either resultCode is not OK or returned data is null or empty: https://github.com/yasirkula/UnityNativeGallery/blob/29566b888db32bc10edfe0fb6307a1049560d801/.github/AAR%20Source%20(Android)/java/com/yasirkula/unity/NativeGalleryMediaPickerFragment.java#L309

I suspect your phone's gallery app has something to do with this. I'd recommend you to try 2 things:

• Try using a different gallery app from Google Play (e.g. Google Photos)
• Try calling this code before calling GetImageFromGallery:

using( AndroidJavaClass ajc = new AndroidJavaClass( "com.yasirkula.unity.NativeGalleryMediaPickerFragment" ) )
	ajc.SetStatic<bool>( "preferGetContent", true );

[KornyAS]

No, this code didn't work, but it did't ask me to select a program, it just opened a file explorer. BTW I tried to use google photos etc but no result

[yasirkula]

Let's hope we'll somehow find the cause of this issue in the near future. For now, I've no clue.

P.S. You can try NativeFilePicker.PickFile( (path)=>blabla, new string[] { "image/*" }); but I don't think it will work either.

[KornyAS]

Yes, it doesn't work either(

[yasirkula]

Can you replace NativeGallery.aar with the attached file (unzip it first to find the aar) and send me the logcat logs again?

NativeGallery.zip

[KornyAS]

Was it a fruitful information?

[yasirkula]

I had a slight hope that another method of getting the data would work but it didn't. Thanks for testing. FYI, this function is called with resultCode=0 (CANCELED) and data=null. So there's absolutely no information provided to the plugin by the gallery: https://github.com/yasirkula/UnityNativeGallery/blob/29566b888db32bc10edfe0fb6307a1049560d801/.github/AAR%20Source%20(Android)/java/com/yasirkula/unity/NativeGalleryMediaPickerFragment.java#L301

[yasirkula]

One last attempt: NativeGallery.zip

You don't have to attach logcat logs this time, I'm only interested if it works.

[KornyAS]

No, it didn't work... Don't know even why, it think that I close gallery instead of selecting a photo....

[yasirkula]

I'm using android.app.Fragment directly instead of Android Support Library's androidx.fragment.app.Fragment class. The latter might have some bugfixes and it is possible (though IMO a low chance) that this issue isn't present in androidx.fragment.app.Fragment.

I'm not using support library because installing support libraries in Unity makes the installation process 5x more complicated. I may come up with instructions to test the plugin with support library in the future to see if it resolves this issue but not at the moment. I'm not hopeful that it'll resolve the issue and I don't want to spend any time on learning support library stuff while I still have other things to do.

[KornyAS]

Maybe if I create an empty project and install native gallery, I will be able to use it on my phone?....

[yasirkula]

If you are talking about using support library, that requires modifying the native source code, as well.

[JaumeBoschAnglada]

Hello, Im'm getting the same error on an Android 11 phone. On Android 9 it works well.
