Android Question StartActivity from Camera2's Activity stops the video preview

[peacemaker]

HI, All

Creating the new thread, as a rule.
If to try to open any other activity by StartActivity - Camera2 sample in video mode stops the video preview, and (when go back to the Main camera activity) it cannot be reset until the app full restart.

*** Service (starter) Create ***
** Service (starter) Start **
** Activity (main) Create, isFirst = true **
** Activity (main) Resume **
LIMITED
Start success: true
/storage/emulated/0/Folder/1554467032966_2019.04.05_16-23-52.mp4
** Activity (main) Pause, UserClosed = false **
Ignoring event: camera_previewcapturecomplete
** Activity (main) Resume **
LIMITED
Start success: true

Event camera_previewcapturecomplete is always ignored.

Any heeelp...

Note that a device with LIMITED support for Camera2 is likely to cause problems.

Try it with CamEx2 example project. Start a new activity and then go back. It should work. If not upload that project.

My old first project (where i moved the code from your sample into my project) is still with this trouble, but the new remade version basing on your example (where i moved my code into your example) is OK for the preview restoring at Release.

Anyway the events "camera_previewcapturecomplete" is always ignored when StartActivity, but going back is correct in your sample. No idea what is the difference.
But solved, thanks.

This is expected. The event is raised when the activity is paused.

I know it's an old thread, but same problem here and maybe this were the solution. My problem was I forgot the cam.stop in Activity_Pause

Sub Activity_Pause (UserClosed As Boolean)
    cam.Stop
End Sub
