Use CameraX

[renanferrari]

Google recently announced CameraX, a Jetpack support library that wraps camera2 capabilities into a much simpler API, based on use cases.

One of those use cases is Image Analysis, which seems perfect to use with MLKit – they even mention it in their documentation as an example.

I'd love to see this app implemented with CameraX. Is this something that would interest you?

So do I. In my option, Camera X is more useful and easy for almost developers. One problem about that Camera X is not support API Level 19(Kitkat).

@renanferrari Yes, it's do in our plan but the priority may be not that high for now. Some factors we need to take into consideration before doing that, e.g.

• CameraX is still in alpha stage and the minimum supported API is 21
• MLKit itself may also require some tweaks to work more nicely with it.

I have been trying to port the implementation with CameraX, however, I haven't been able to yet. The question I have is will it not be a problem if we keep using the deprecated Camera API? Our app uses minimum API 21, and I think most of the apps in market are following the same, as there are very less devices below 21 now a days. So please suggest which one would be the best to follow this implementation.

Update: Right after I posted, I have been able to get some success with CameraX. Took a reference from Crysxd's implementation. However, still modifying for multi object detection.

Would really love to see this example with CameraX, any progress?

[spacemx09]

I have been successfully able to implement multiple object detection using CameraX with the help of crysxd/Object-Tracking-Demo and this demo. I will make it available once I get a little time. Also, we cannot put it in production as CameraX is in alpha. So I would suggest to try Camera2 if you need the feature to be in production right away.

I am still not sure if it is still okay to use Camera API as it is deprecated. Though it works fine on all the API upto the latest Q.

Anybody here to me that how to put the captured photo in any view like (imageview, textureview, etc) in android.

Since android.hardware.Camera was deprecated in API level 21.

I think the project should use Camera2 or CameraX if it is out of beta. (both require API level 21)

Agree with @kenz, we should move forward.

I am working with an application that min-sdk is 19 and I cannot change. There is no problem with camera x, to be used only in 21. But I could import it into the project and limit it with if (Build.VERSION.SDK_INT). And not in the build.

[nelson336]

tools:overrideLibrary="androidx.camera.core" to force usage ??

[nelson336]

That if I can import camera x on android, I can use camera 1 for sdk less than 21 and for larger use camera x.
