BUG: No preview of photos

[mgursch]

Hello,

I integrated your library into one of my apps but Its showing some weird behavior. First I open the PhotoPickerFragment - everything works. I choose 1-2 pictures. Second the user opens the PhotoPickerFragment again, but image previews are not visible. If the user navigates to gallery and back, previews are back.

I attached a link to a video for better understanding.

Which library do you use for ImageLoader?

[mgursch]

Glide with your demo implementation

@APetjko
How can I help to get a solution for that?

[APetjko]

As I can see, you run app on Android Q. Tried to reproduce on emulator with this version, but succeed only partially.

Images was not loaded at all (but it is know issue on Glide repository - bumptech/glide#3896).
You can try suggested in this issue solution, but i'm not sure that it will help you.

Can't reproduce your case.

@mgursch maybe you have some additional configurations for Glide? (extended AppGlideModule, Caching, etc.)

I tried to switch to Picasso for ImageLoaderDelegate and it works. Maybe there is some missconfiguration or Glide issue

[APetjko]

Do you experience this issue on pre-Q versions?

Sorry - havent checked it on other phones.

<cache-path
    name="camera"
    path="camera/" />
<external-path
    name="external_files"
    path="." />
<external-path

Adding android:requestLegacyExternalStorage="true" to application tag in AndroidManifest.xml worked for me.
