Android Question Camera2 problem

[jdonth]

I am trying to compile the camera2 example (https://www.b4x.com/android/forum/threads/camera2-still-images-and-videos.83920/) and am getting the following error thread:

I tried this sample some monthes ago (guess, it was B4A 7.8) and tried now (B4A 8.30)
No problems with compilation.
Camera2 is enough complex, for my app I used intents. But this is another story.

You use Java 8 instead of Java 10. Doubt that this is important here.
Try to update everything in SDK manager and check android.jar path (better to set to android-27).

Java 8 is completely fine.

Try to update everything in SDK manager and check android.jar path (better to set to android-27).

That's probably the problem.

Make sure to use B4A Sdk Manager: https://www.b4x.com/b4a.html#installation
