Unable to start activity Component Info [movement between 'activity' by using Intent]

Question

Hello Everyone Thanks for reading my question

I tried to make an application which if the button in a main_activity[main view] get a click signal, Call another Activity View with Camera SurfaceView on it.

But, I've seen an 'Unable to start activity component' error in the part where I keep calling up the activity_camera.xml document.

Even though I looked up and applied various postings related to the error, I still didn't know where to go wrong and how to fix it, so I take the liberty of asking you a question.

Here are my errors and codes

I apologize in advance for the long passage. This is the only place I can hope for, because I've been up all night over this problem for three days and nothing is getting better.

I hope you all take care of your health and have a peaceful.

Thank you for your opinion. I will revise it and upload the stack trace soon! Sorry for the inconvenience. — J4BEZ, Mar 11 '20 at 09:21
@MikeM. Stack trace has been modified to text! (I'll leave the picture pointing to the line that the source code wrote showed an error!) — J4BEZ, Mar 11 '20 at 09:26
The `CAMERA` permission is a dangerous permission, and you need to request it at runtime on Marshmallow and above, if your `targetSdkVersion` is 23+, which is likely, these days: https://stackoverflow.com/q/32635704. For a quick test, you can manually enable that permission on your app's page in the device Settings, to make sure that's the cause of the current issue, before you dive into implementing all that permission code. — Mike M., Mar 11 '20 at 09:32
@MikeM. Wow...!! If Android 6.0 or higher or sdk version 23 or higher, we need to bring a little more safely permission!! Thank you for the great tip! during the method you gave me(Settings -> Apps -> Permission) I found that my App's Camera Permission was actually denied. When I allowed it, It became Work!! — J4BEZ, Mar 11 '20 at 09:48
I think I can finally get a good night's sleep. Thank you so much. Have a nice day!!! >A — J4BEZ, Mar 11 '20 at 09:49
No problem! Here's a similar question with some example code, to get you started: [ERROR: failed to connect to camera service @ Android marshmallow](https://stackoverflow.com/questions/37458157/error-failed-to-connect-to-camera-service-android-marshmallow) — Mike M., Mar 11 '20 at 09:53
Wow.. Thanks for your recommendation!!!! I'll modify my code!! Thank you very much!! — J4BEZ, Mar 11 '20 at 09:59
