Get rid of RenderScript about binaryeye HOT 4 CLOSED

Why?

from binaryeye.

1. It seem to be used only for screen rotation.
2. it carries native libraries, XPrivacy has problems with isolating apps with native libs

Yes, RenderScript is used for rotation of the camera frame, but also for downsampling the frame. Both operations don't require RenderScript, of course, but RenderScript is - at least in theory - the fastest way to perform these operations. In practice, performance can vary wildly because RenderScript is an abstraction that is executed either on CPU or GPU depending on what's available on a device. And yes, it's run by native system libraries that also vary very much between vendors and versions.

So it's not an unencumbered choice for sure. At some point, I already made RenderScript optional (in a development build) because I was wrestling to get RenderScript to run on Lineage devices.

Also, RenderScript seems to not get much love from Google itself because building an App Bundle results in a corrupted build. Which is why Binary Eye is stuck with heavy APKs at the moment.

On the other hand, it's still the fastest option for most devices. And I care for speed because the faster the camera image can be processed, the more images can be processed in a given time. And this means barcodes can be recognized faster just simply because there are more images to work with.

What makes things worse is that ZXing isn't exactly fast too. It's full of allocations in the hot path and it often transforms data when it would be faster to just read them with a different algorithm.

So dropping RenderScript would have some benefits but also some serious drawbacks. The only option I see is making it optional for devices where it doesn't run well. What would you think of a switch in the settings for this? Of course, Binary Eye would still include RenderScript libraries in that case.

Thanks for the info. I have assummed that a GPU is always available.

This was my fault. I have allowed loading libs but have not allowed exec. After I have allowed exec it runs fine.
