Set flash mode in android -


i got example set flash mode, cant make work. using in camera swap:

        final imagebutton button1 = (imagebutton) findviewbyid(r.id.bt_camera);     button1.setonclicklistener(new view.onclicklistener() {         public void onclick(view v) {             camera.release();             idcam.id = idcamera(idcam.id);             camera = camera.open(idcam.id);             camera.parameters parametro = camera.getparameters();             parametro.setflashmode(parameters.flash_mode_on);             camera.setparameters(parametro);             camera.startpreview();                 try {             camera.setpreviewdisplay(camholder.id);             } catch (ioexception e) {                 e.printstacktrace();             }         }     });

without flash parameters, swap works fine.

included in manifest permission:

<uses-feature android:name="android.hardware.camera" /> <uses-feature android:name="android.hardware.camera.autofocus" /> <uses-feature android:name="android.hardware.camera.flash" /> <uses-permission android:name="android.permission.camera" />

but log returns:
