Problem when testing on Android Device

[carlosmellado]

Everything was working fine for iOS but when switched to android, I got the following error as soon as I call at
BackgroundRemover.removeBackground
The error says:

There was a problem loading the project.

Could not invoke
BackgroundRemover.removeBackground

null

No content provider. http://the_image.url/url.jpg

Would it be possible for you to share the device model and the brand? Also a stack trace would be really useful.
Another question is, is this a build-time or a run-time issue?

[carlosmellado]

It's a Xiaomi MI 8, running MIUI Global 12.0.3 with Android 10 QKQ1.190828.002
The issue is happening in runtime, at the moment I call the function.

I'll try to get the stacktrace as it wasn't appearing to me. I'll try running Android studio directly to check if I can get any info

I see this on the react native console when crashing:

@atlj did the log helped in something?
Do you need more info?

[atlj]

Hey yeah, thanks for the logs and the device info. Sorry I'm running pretty busy for a while noe so couldn't find enough free time to come back to this. Will take another look once I find some time.

Aww seems like class is not prepared to work with remote URIs, only local files, right?

[zoobibackups]

there is an issue in this library when i take picture from camera like putting the signature on paper and take picture to remove background and result of the image is black
before i remove the background

after the result

@atlj

[carlosmellado]

For me it doesn't work on android. Doesn't work with remote images and for local images the background is turned black too 🥲

I tried to make the fix and I have it working with remote images but still having the black background result

[raahimkhan]

I am getting the same exact error on Android. Any fixes yet?

[qaezrun]

Same here on android emulator api 33, yes it removes the background but not transparent. Its now color black. What im planning here is to add custom background color.

Hoping this gets fixed this is the only library i've seen that does not require making backend and can be directly use on react native.

[carlosmellado]

Well, I fixed the issue and the solution is on a pending PR. Hope it helps!
