I'm developing a Service, running in background, that uploads succesfully images and data to the web.

Now I want to upload an image taken by the Camera.

Is it possible to use the camera in a background service without preview on Android 2.2?

I found various contrastants answers on web...

How can I do it?

回答1:

You can take pictures without preview with an dummy view.

like:

SurfaceView view = new SurfaceView(this);
c.setPreviewDisplay(view.getHolder());
c.startPreview();
c.takePicture(shutterCallback, rawPictureCallback, jpegPictureCallback);

It's not possible without the preview / surface view.
