I want to open the camera but not in photo form so I can add an overlay. I just need the camera to display what is shows but not to take the photo if that makes sense... How can I do this?
maybe this article help you open camera view in your app by creating your own view and open camera in its own different thread ,
as it might take time to load and this will result in the lagging UI.
Maybe this article from android developers website will help you achieve what you want.

I am using this plugin within an Ionic app to view my device's camera and then stream over RTMP - https://github.com/disono/cordova-rtmp-rtsp-stream
This works great, but I need the Ionic webview to appear over the top of the camera so that I can show images & text on top of the camera view. Can someone tell me how to edit the plugin to place the camera view behind Ionic's webview please?
Unfortunately I do not know the Java language, but I believe the file that requires editing may be RTMPActivity.java
Thanks in advance for any help.
I am working on android app. Currently my app is used as a viewer for camera.

I don't think so.
I am a new developer, trying to get my head around android. I managed to get fragments working and I am unable to add and play a video on it.
Also, I added a image successfully, is it possible to pinch zoom on that image, if so how?
I really appreciate your help.
Thanks
You can implement this library
https://github.com/chrisbanes/PhotoView for zoom on image.
if you read the Sample Usage and analyse the sample app you can zoom it.
About playing video on fragment. It is simple just google it.
Can the android camera be programmatically set to send gray scale images.
I'm not asking about conversion after the images have been received, I'm asking for a way to programmatically set it like we do with fps, resolution etc.
Are you talking about the built in camera app (via an intent) or inside your app?
If it's the built in camera app, i don't think it's possible, and even if it was , you can't assume it will work the same on all devices, since many of them have customized camera apps.
About camera within your app, yes, you can do it, and there are examples out there how to do show things on the camera based on its content , like this one
