I suggest switching to https://github.com/shaithana/cordova-plugin-wezka-nativecamera which has a superior UI. I have an active fork at https://github.com/mWater/cordova-plugin-wezka-nativecamera until some fixes are merged.
This is a fork of the official camera plugin from Apache.
It uses a custom activity to run in the foreground in Android to prevent Cordova from being killed.
It is adapted from https://code.google.com/p/foreground-camera-plugin/
To install this plugin, follow the Command-line Interface Guide.
If you are not using the Cordova Command-line Interface, follow Using Plugman to Manage Plugins.
