Android 6.0 RuntimeException: Fail to connect to camera service

Question

An error occurred with my app which ran in Nexus5 (Android6.0).

The error was

java.lang.RuntimeException: Fail to connect to camera service

Answer 1

This happens because, in Android 6.0 the permission model is different. You have to implement the new permission model which asks for the permission on run time. Even if you don't ask it, you can manually enable it in the phone's app setting, but that is not gona work when you publish your app in the play store. Here is an Article on How to get Run time permissions
