Slightly modify the Camera intent

Question

I need to slightly modify the default camera intent in android - for example I want to start the camera in 360p quality, when starting front camera to be the active one and to be oriented in landscape. I have done a research and find some put extra options that could be used but it seems they do not work properly. So i think that the best way to do this is to find the build in camera intent code and do some modifications.

Where I can find the source of the build in camera intent and also the meta data part in the manifest(if there are some specific options to start the intent)?

I am going to guess that by "default camera intent" you mean an Intent for ACTION_IMAGE_CAPTURE.

I have done a research and find some put extra options that could be used but it seems they do not work properly.

For ACTION_IMAGE_CAPTURE, there is no extra to force 360p, and not all cameras support that resolution. There is no extra to force a front-facing camera, and not all devices have a front-facing camera. I am skeptical that EXTRA_SCREEN_ORIENTATION will do what you want, and there is no requirement that any camera app must support EXTRA_SCREEN_ORIENTATION.

So i think that the best way to do this is to find the build in camera intent code and do some modifications.

I am going to assume that by "build in camera intent code" you mean "built-in camera app".

Few manufacturers ship the AOSP camera app. They replace it with their own. The source code for their own camera apps will be in their offices.
