Change camera resolution setting programmatically in android

Question

I'm using the below code to open the camera. Is it possible to set the camera resolution to high programmatically?

private void openDefaultCameraApp() {
    Intent i = new Intent(android.provider.MediaStore.ACTION_IMAGE_CAPTURE);
    startActivityForResult(i, CAPTURE_PHOTO_CONSTANT);
}

Answer 1

You must add an MediaStore.EXTRA_OUTPUT to the intent. In the extra, you have to specify a Uri for the picture to be saved to. This will save the full resolution image, otherwise, it will just snap a small image.

Refer to the Android docs: ACTION_IMAGE_CAPTURE

Standard Intent action that can be sent to have the camera application capture an image and return it. The caller may pass an extra EXTRA_OUTPUT to control where this image will be written. If the EXTRA_OUTPUT is not present, then a small sized image is returned as a Bitmap object in the extra field. This is useful for applications that only need a small image. If the EXTRA_OUTPUT is present, then the full-sized image will be written to the Uri value of EXTRA_OUTPUT

I think its not possible see the link below :

Open Android Camera in lower resolution with ACTION_IMAGE_CAPTURE

You have to manually set the resolution from camera preview screen.

If you are getting small snap even if your camera resolution is set to high then use Zed Scio's approach.

You can use this method to get all supported sizes of pictures.

public List<Camera.Size> getSupportedPictureSizes ()

You will get a List of supported Picture Sizes. And then from this, you can set whichever size you want to using this method.

public void setPictureSize (int width, int height)
