Take a photo automatically without user interaction

Android does not allow you to take picture without showing the preview window. So you have to make the surface view very small. Like 1*1 pixel and put it in a corner of any control. Or show a dummy surface view to do this.

Picture taken with camera intent is low quality on ImageView (7.0+) [duplicate]

If you are asking “how do I get a full-resolution image?”, supply EXTRA_OUTPUT on the ACTION_IMAGE_CAPTURE Intent, then look at that location for the image when onActivityResult() is called with RESULT_OK for your request. This sample app illustrates the technique, using FileProvider for better compatibility on Android 7.0+: /*** Copyright (c) 2008-2017 CommonsWare, LLC Licensed … Read more

Android: BroadcastReceiver intent to Detect Camera Photo Taken?

Right now, I’ve gotten a BroadcastReceiver implemented that’s currently listening for “android.intent.action.CAMERA_BUTTON”. However, this doesn’t seem to get called when I’m wanting it to. That only gets broadcast if the foreground activity does not consume the event.

android camera: onActivityResult() intent is null if it had extras

It happens the same to me, if you are providing MediaStore.EXTRA_OUTPUT, then the intent is null, but you will have the photo in the file you provided (Uri.fromFile(f)).
