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

Question

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 can't do that with an intent. The intent opens up other apps. You have to make your own camera app. Folow [this](https://developer.android.com/guide/topics/media/camera.html#custom-camera) for instructions — Drilon Blakqori, Aug 19 '16 at 13:34

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

Thank you but it has error when i run in my device. I reported in https://github.com/omaflak/Android-Camera2-Library/issues/2 – Jame Aug 19 '16 at 13:44
And I also want to use Build-in Camera app in Android. Is it possible? – Jame Aug 19 '16 at 13:51
As far as I know you can't, your app will close when you start the intent... (Check out the git discussion, I posted the solution) – Omar Aflak Aug 19 '16 at 14:26
Thank you. Let discuss your issue in git – Jame Aug 19 '16 at 14:31
