Thanks again...
Hi
Excellent tutorial, thanks for sharing your knowledge, I have a
query ... I add an opaque background and an image on the view (macro)...but when I
take a photo not recorded...this is the image http://dl.dropbox.com/u/46059390/fotos/imageOverlayAndroid.JPG
the upper image is in main.xml and the other in the same control.xml ...have any idea how to do this
App crashes when clicking the button, unless you add
to the manifest.
Great tutorial!
hello widi,
In the code, u know where the image saved. Such that you can load the image from it. Refer to Scale bitmap Efficiently.
Very well-explained tutorial...
now I can make a working front camera app by following your step by step explanation
I Like it :D
Best tutorial on camera.Great work.
I got a question. Lets say i took a picture and saved it then i wanted to leave AndroidCamera actiity and start another one.
How can i do that? I've tried many ways but it always crashes. I guess it's because of SurfaceView.
Can you please help me about that?
tks for tutorial. But how can I take byte[] from a picture to so something else?
I have public byte[] and do this
Camera.PictureCallback myPictureCallback_JPG = new Camera.PictureCallback(){
@Override
public void onPictureTaken(byte[] arg0, Camera arg1) {
// TODO Auto-generated method stub
pictureBin = arg0;
bitmapPicture = BitmapFactory.decodeByteArray(arg0, 0, arg0.length);
}};
But it's alway null when I take picture ??
Why the pictures I take are black?
