Question

To check whether camera is running or not i am writing these code

ActivityManager actvityManager = (ActivityManager)this.getSystemService(ACTIVITY_SERVICE);
    String packageName = actvityManager.getRunningTasks(1).get(0).topActivity.getPackageName();
    if(packageName.equals("android.hardware.camera")||packageName.equals("com.android.camera")){
        Camera_status = "STATUS_ON";
        System.out.println("===on===");
    }else{
        Camera_status = "STATUS_OFF";
        System.out.println("====off====");
    }

By using this, i am able to get correct result in android emulator but while testing In real device i an not able to get the correct result.As per the answer posted here by CommonsWare,i think he is correct.So friends may i know how to get the camera on/off status programmatically.

Try This its working!!!

Camera _camera;
    boolean qOpened = false;
    try {
        _camera=Camera.open();
        qOpened=(_camera!=null);
        if(qOpened){
            Camera_status = "STATUS_OFF";
        }else{
            System.out.println("==nothing to do====");
        }

    } catch (Exception e) {
        Camera_status = "STATUS_ON";
        System.out.println("=====Camera running=====");
    }
