Vector Camera v 1.2.3 Crash when clicked several times quickly on android 7.0

[ammarraisafti]

Expected behavior

It should, when clicking multiple times quickly in image capture icon or start video, this app does not crash.

Actual behavior

Initially, I accidentally clicked several times quickly on the image capture icon or start the video. Furthermore, without me realizing this application suddenly crashes and stops. Then I tried re-implementing the behavior, to make sure that the behavior was real, or actually happening, causing the application to crash and stop. Also to ensure that this problem is purely technical. It turns out after I tried to do it, the application again broke down and stopped. So, the actual behavior I can conclude well. That is when clicking multiple times quickly on the image capture icon or start video, can cause this application to crash and stop.

How to reproduce

1. Launch app.

2. Click a few times quickly on the image capture icon.

3. Press the back button to exit the captured image.

4. Click the camera icon, to switch to video mode.

5. Click several times quickly on the video start icon.

6. You will find a problem as I have experienced, the application suddenly crashes and stops.
