I am following the tutorial for building a camera app http://developer.android.com/tools/device.html and I am my call to Camera.open() returns null. I've declared the permission in the manifest and I tried both on the emulator and a xyboard and I am still getting null. Does anyone know any quick hints?
Camera c = null;
try
{
c = Camera.open()
}
catch(Exeption e)
{
}
return c;
Keep in mind, I am not throwing an exception, I am simply getting NULL back.
That's because it's not supposed to throw an exception. It returns null when no back-facing camera is found:
Creates a new Camera object to access the first back-facing camera on the device. If the device does not have a back-facing camera, this returns null.
You may be trying to access a front-facing camera, in which case you probably want to use open(int cameraId). (See the other answer for an example of using it)
Here is a really great tutorial for working with the android camera
You'll notice thru out the code there are toasts/alerts that will help guide you to what is happening
In order to get this working, I had to use the Camera.open(0) which meant that I had to change the API level in the manifest from 8 to 9. I am now getting an Error 100 though...
