Grabbing a picture from within an App?

I want my Android app to take a picture, as part of something larger it is doing.

Ideally, I would like to just开发者_运维问答 send out an Intent saying "snap a picture" and get back an image file.

Is there an Activity that can handle that, or do I need to do all the low level work with the Camera class myself?

Thanks,

Peter

You can invoke the default camera activity using an Intent and startActivityForResult(). You can also construct a Uri and file name for the image and pass that to the photo capture activity. When the user takes a photo it will be saved with that name at the location you've specified.

Intent intent = new Intent(android.provider.MediaStore.ACTION_IMAGE_CAPTURE );
intent.putExtra( MediaStore.EXTRA_OUTPUT, outputUri );
startActivityForResult( intent, 0 );

If the user cancels the capture then a result of 0 is returned, and if they take a photo and approve it, a result of -1 is returned.
