I am trying to create a app with which you can take secretly a picture. So my goal is to capture a picture when a button is clicked and then save the taken picture in the gallery without calling the local Camera app.
Thank you for your answer in advance...
If you want to conceal the application then I suggest you to look at this link

I am new with android studio and I have a question about camera.I have done the Take photo tutorial and now I have a button that opens my camera app. I want to take the color of a pixel from the camera app without saving the picture.
It is possible or I need to make camera API in order to take that color?
Any suggestion or tips about how I can make this project are welcomed.
Android camera intent either saves an image file, or it is cancelled. You need camera API approach to catch pixels without creating files. You can use a library like fotoapparat to wraps the tricky API for easy usage.
I'm working on a application and i want to take the picture of the user automatically with front camera without opening the camera or with a little preview.I can take the picture but the user have to click the button but what I want is it takes picture automatically.

Using the camera API you can achieve this.

I am making an application where the user has to be suggested about the quality of the picture he is about to take.
Like "Brightness is low" and "Your environment is dim".
To achieve this, we need to put an overlay message on the camera preview while the user is viewing the subject.
Does anyone have an idea on how could we take the image brightness from the camera preview by using sensors or some other way in live mode even before the picture is taken?
Any help would be appreciated.
Using the camera parameters as pointed out by #appleskin, would either of these methods help? setWhiteBalance() or setExposureCompensation().If you want to achieve this functionality at run time then use native NDK effect for brightness.you can easily got .so files from github just use according to your further requirement.
In my app, I'm using the built-in camera app to take pictures.
The thing is that this interface has a button to change camera ( to front) and when I take a picture with front picture, it is not working anymore.
So, Is there a way to take picture fromt front camera with built-in camera app.
If it is not posible, is there a way to remove the icon from built in app???
Any suggestion will be appreciated!
