How to draw on a photo IMMEDIATELY after taking it, THEN save to storage

I have searched around and found a few different solutions to this problem but none of them are really what I am looking for.
I am developing an app that lets the user take an image by opening the camera via a MediaStore.ACTION_IMAGE_CAPTURE Intent as so...
Intent intent = new Intent(MediaStore.ACTION_IMAGE_CAPTURE);
And then saves the image with
File photo = new File(Environment.getExternalStorageDirectory(), titleOfPhoto + ".jpg");
intent.putExtra(MediaStore.EXTRA_OUTPUT, Uri.fromFile(photo));
I even get the thumbnail back and display it for the user in the onActivityResult() Override.
As the title suggests, what I would like to do is allow the user to draw on the captured image immediately after taking it. But I have no control over what happens between opening the camera and returning to my app with the captured image already saved. Apps like SnapChat and WhatsApp are doing exactly this and so much more, so I know it is possible, but Android does not appear to have this capability built in.
To be clear: The sequence of events needs to be
1) Open the camera
2) Take a picture
3) Draw on the picture
4) Press 'Ok'/'Done' or something
5) Save the edited photo
6) Return thumbnail
Is there anyway to add an event listener to the camera, or open the camera in a different manner that gives more control? Any help is appreciated! Thanks!

In order to do this, you will have to use the Camera Framwork API.
The basic of this is to render the camera output on a Surface View in your app. Then when the user takes a picture, capture the state of the surface view. From there you can allow your users to draw on the picture. When they are finished, THEN save the picture and display its thumbnail.

How to autmatically capture and save image without press capture button in Android?

I am using Android 5.0 to implement an application which allows to automatically capture and save an image into my phone. Currently, I am using bellow code but it requires press the capture button in Capture UI of my phone. Is it possible to capture and save the image without press the capture button? For example, I just call the function myCaptureandSave(), then the phone will display Capture UI and intermediately capture the image and save, I do not need doing more step.
public void myCaptureandSave() {
String image_path = Environment.getExternalStorageDirectory() +"/"+System.currentTimeMillis()+".jpg";
Intent cameraIntent = new Intent(android.provider.MediaStore.ACTION_IMAGE_CAPTURE);
//File dir = Environment.getExternalStoragePublicDirectory(Environment.DIRECTORY_DCIM);
File output = new File(image_path);
cameraIntent.putExtra(MediaStore.EXTRA_OUTPUT,Uri.fromFile(output));
startActivityForResult(cameraIntent, CAMERA_PIC_REQUEST);
}

You have to use Camera Api. Create Service, running in background, which hold reference to this api and current SurfaceTexture, it is necessary, camera will be 'previewing to nowhere'. after that you'll be able to take pictures even if device is locaked

Yes it is possible, but I believe you can't do it using the internal camera (calling the intent). You have to use Camera2 API.
I made a library to use Camera2 API, you can take a look at it if you want:

In your case, simply pass a dummy SurfaceTexture for the preview and call takePicture().
Hope it will help

how to capture an image in background without using the camera application
i tried with this time ago and with little bit changes i got it.
Hope this helps..

Avoiding the preview after taking pictures with the integrated camera

I want to take a photo with the camera app which is default on the device. After taking it I have my own preview on which the user can input a text and accept the picture or refuse it. This already works fine.
My problem is now that some user has activated the preview option in the default camera app. Is there a parameter for the Intent to deactivate the default setting and send the picture directly to my app without a preview? I don't find a documentation for this case...
I start the camera with the following code
Intent takePictureIntent = new Intent(MediaStore.ACTION_IMAGE_CAPTURE);
if (takePictureIntent.resolveActivity(this.getPackageManager()) != null) {
this.startActivityForResult(takePictureIntent, MY_CAMERA_REQUEST_CODE);
}
The alternative is to create a own camera in my app. But this is in my opinion a little bit oversized.
Thanks in advance for any help.

There is no possibility to disable the preview programmatically. If something different is needed as the settings of the default camera, an own camera has to be implemented :-(

Launch native camera app with option to capture either video or image

I've written an app before where I open the native camera app to capture an image like this:
Intent takePictureIntent = new Intent(MediaStore.ACTION_IMAGE_CAPTURE);
Or, like this for capturing video:
Intent takeVideoIntent = new Intent(MediaStore.ACTION_VIDEO_CAPTURE);
But is there a way to open the native camera app with the option to capture either video or an image? I'd like to open to the image given below, where the user can swipe to access the side-menu and change their input type.
I've tried searching, but no results have come up yet. I'm not sure if there is a way to do this without writing a custom camera implementation, which I'd like to avoid for now.
If this is possible, how can I do it? And how could I go about recognizing what media type the user has chosen once the capture is complete (in onActivityResult, probably)?
Thank you in advance!

Currently As specified by you there are 2 intents for capturing image and video i.e. MediaStore.ACTION_IMAGE_CAPTURE & MediaStore.ACTION_VIDEO_CAPTURElink.
For intially I was also thinking startActivityForResult (Intent intent, int requestCode, Bundle options), Here options param was used to give the extras for the external applications but we can only specify some animations not the values as specified link1 & link2.
Solution
I would rather suggest you to go for the custom app with options as you like rather than the restrictions given by the existing camera app.

Android camera intent confusion

I am working on an app in which i have to click a pic a pic and save it to a specified folder. I am using android.provider.MediaStore.ACTION_IMAGE_CAPTURE in intent to invoke the camera .I am done with coding and my activity is working fine.But now i have a question in my mind that whether i should stick with this code or i should use the code given here.Need your precious suggestions on this topic.
Thanx in advance.

If you want to just click a picture and save it to a specified folder nothing more then You can use Intent and call ACTION_IMAGE_CAPTURE, it easy to let handle on camera activity do your stuff,
And If your application has some serious deep work with camera when you want to modify preview screen size, and all those things,(For this you have to handle all things like to manage camera, and when to release it, check for don't freeze main UI..) then you have to go with the code you suggested...
Choice is yours.....

I suggest you use the code from your link.
Because most of the stock camera apps don't work as expected with Image Capture. For example the Galaxy S2 and most other Samsung and HTC phones give you the picture bytes back and also save the picture in the standard DCIM Folder on SD-Card, if you want it or not.

public void imageFromCamera() {
Intent intent = new Intent("android.media.action.IMAGE_CAPTURE");
if (!Environment.getExternalStorageState().equals(Environment.MEDIA_MOUNTED)){
Log.d(TAG, "No SDCARD");
} else {
mImageFile = new File(Environment.getExternalStorageDirectory()+File.separator+"MyApp",
"PIC"+System.currentTimeMillis()+".jpg");
mTempImagePath = mImageFile.getAbsolutePath();
intent.putExtra(MediaStore.EXTRA_OUTPUT, Uri.fromFile(mImageFile));
startActivityForResult(intent, TAKE_PICTURE);
}
}
this what u r searching i am thinking..
