Unable to take image using front camera: Android -


i unable take pictures using front camera. test device definately has both front , camera/functionality. reason pictures being taken camera. here have. note: camera , parameter globally set.

@override    public void surfacecreated(surfaceholder holder)    {              camera = camera.open();             parameter = camera.getparameters();              camera.size size = getbestpreviewsize(surfaceview.getwidth(), surfaceview.getheight(), parameter);             parameter.setpreviewsize(size.width, size.height);              try {                 camera.setpreviewdisplay(surfaceholder);             } catch (throwable ignored) {                 log.e(tag, "set preview error: ", ignored);             }             camera.setparameters(parameter);          }       }

in surfacechanged() start camera preview.

@override     public void surfacechanged(surfaceholder holder, int format, int width,                                int height)     {         // todo auto-generated method stub         if(ispreview == true)         {             camera.stoppreview();             ispreview = false;         }          if (camera != null)         {             try             {                  camera.setpreviewdisplay(surfaceholder);                 camera.setdisplayorientation(90); camera.startpreview();                 ispreview = true;             }             catch (ioexception e)             {                 // todo auto-generated catch block                 e.printstacktrace();             }         }     }

in surfacedestroyed() release camera resources

@override    public void surfacedestroyed(surfaceholder holder)    {        if (camera != null) {            camera.stoppreview();             camera.release();            camera = null;            ispreview = false;         }     }

here referenced method returns preview size

private camera.size getbestpreviewsize(int width, int height,                                            camera.parameters parameters) {         camera.size result = null;          (camera.size size : parameters.getsupportedpreviewsizes()) {             if (size.width <= width && size.height <= height) {                 if (result == null) {                     result = size;                 } else {                     int resultarea = result.width * result.height;                     int newarea = size.width * size.height;                      if (newarea > resultarea) {                         result = size;                     }                 }             }         }          this.size = result;         return (result);     }

whenever want use front camera--the front camera additional feature, camera used--i call frontcamera() method. method set camera-id 2, believe flag frontcamera(). set parameters updated parameters , take picture.

    private void frontcamera() {          parameter = camera.getparameters();              cameraid = findfrontfacingcamera();              if (cameraid < 0) { //no front face camera              } else {                  parameter.set("camera-id", 2);                 camera.setparameters(parameter);             }              camera.takepicture(null,                     null, mypicturecallback_jpg);      }

my check front face camera done in findfrontfacingcamera() method

private int findfrontfacingcamera() {         cameraid = -1;         //search front facing camera         int numberofcameras = camera.getnumberofcameras();         (int = 0; i<numberofcameras; i++) {             camerainfo cinfo = new camerainfo();             camera.getcamerainfo(i, cinfo);             if (cinfo.facing == camerainfo.camera_facing_front) {                 log.d(tag, "front camera found");                 cameraid = i;                 break;             }         }         return cameraid;     }

final notes: numberofcameras returns 2, indicating test device has 2 cameras. also, reaching "front camera found" tag further convinces me not hardware issue. whatever reason, code take images camera. ideas? in advance.

don't use .open(). use .open(cameraid) , pass camera id of front facing camera.

i have detailsview control on page used edit various fields of record, works in respect. i looking way add 1 column (and if works, why not more) right, absolutely read-only, show same fields of record comparison purposes. i aware there no obvious way such thing out of box detailsview . have looked other controls (transposed gridview , recommended formview , listview ), nothing satisfies. have special data binding setup using detailsview , can't out of without losing features. anyone on how "hack in" additional columns (for display only) on detailsview ? the solution have now, use second detailsview , visible set false in aspx. in code, make sure databind hidden detailsview hosts data third column first, initial detailsview named itemdetails . and in item created event, pass third column html rendering of hidden controls (in last code block) : protected void itemdetails_itemcreated(object sender, eventargs e) { if (dataite
