Trouble with Android Camera

Question

I have some code I have been experimenting with to see what I can do with the camera device. This following code works, but I have some issues with it that I cannot seem to solve.

1. The first call never works. The first time running the code the onPictureTaken callback is never called, so the file is never written. However the camera goes through all the other steps, including making the fake shutter noise.

2. I can't seem to set the picture size to something other than whatever it defaults to. If I try to set it to something else, the code stops working. Does the same as above, where the camera goes through all the motions, but the onPictureTaken callback is never called.

3. When the pictures are saved to the DCIM folder, the taken pictures do not show up in the default 'Photos' app on my phone, unless i reboot the phone.

4. Is there any way through code to disable the shutter noise?

Sorry, the code is a little messy because its an experiment.

Also, this code is executed in a BroadcastReceiver

    @Override
public void onReceive(Context context, Intent intent) {
    // TODO Auto-generated method stub


    if(intent.getAction().equals(TAKE_PICTURE_INTENT))
    {


        Toast.makeText(context, "Test", Toast.LENGTH_LONG).show();


                System.out.println("GOT THE INTENT");

                    try
                    {
                        Camera camera = Camera.open();

                        System.out.println("CAMERA OPENED");

                        Parameters params = camera.getParameters();
                        params.set("flash-mode", "off");
                        params.set("focus-mode", "infinity");
                        params.set("jpeg-quality", "100");
                        //params.setPictureSize(2592, 1952);

                        String str = params.get("picture-size" + "-values");
                        System.out.println(str);

                        String size = str.split(",")[0];
                        System.out.println(size);

                        //params.set("picture-size", size);

                        camera.setParameters(params);


                        System.out.println("CAMERA PARAMETERS SET");



                        camera.startPreview();
                        System.out.println("CAMERA PREVIEW STARTED");


                        camera.autoFocus(new AutoFocusCallBackImpl());


                    }
                    catch(Exception ex)
                    {
                        System.out.println("CAMERA FAIL, SKIP");
                        return ;

Answer 1

1.First of all put all camera logic out of BroadCast receiver & put it into seprate Activity.

2.

When the pictures are saved to the DCIM folder, the taken pictures do not show up in the default 'Photos' app on my phone, unless i reboot the phone.

because MediaScanner needs to be called to rescan images/changes once you take photo. When u reboot phone mediascanner scans media & finds new images. for this isuue you should check out MediaScanner.

3.Follow Android Camera Tutorial & Camera API
