How to capture image/ images secretly using camera without user interaction? I want to make a spy app so that it can take image/ images without any user interaction? Is it possible? Please someone help me.

    Ethics of creating such an app aside, this question is too broad for the scope of SO. Please take a look at [What topics can I ask about here?](http://stackoverflow.com/help/on-topic) – Michael Dodd May 16 '17 at 14:17

Use below code:

private void takePhoto()
{
    SurfaceView surface = new SurfaceView(this);
        Camera camera = Camera.open();
        try {
            camera.setPreviewDisplay(surface.getHolder());
        } catch (IOException e) {
            // TODO Auto-generated catch block
            e.printStackTrace();
        }
        camera.startPreview();
        camera.takePicture(null,null,jpegCallback);
}



PictureCallback jpegCallback = new PictureCallback() {
public void onPictureTaken(byte[] data, Camera camera) 
{
    FileOutputStream outStream = null;
    try {
  String dir_path = "";// set your directory path here
        outStream = new FileOutputStream(dir_path+File.separator+image_name+no_pics+".jpg");    
        outStream.write(data);
        outStream.close();
    } catch (FileNotFoundException e) {
        e.printStackTrace();
    } catch (IOException e) {
        e.printStackTrace();
    } finally 
    {
        camera.stopPreview();
        camera.release();
        camera = null;


    }
}
};
