Of course, your emulator does not have a camera, until or unless your allow it to use your computer's camera. — Lakhwinder Singh, Dec 08 '15 at 11:01
there is a option , while creating an emulator to use back camera and front camera, if you are using android studio then you should clone your device, it will let you customize the device specifications, and there you can choose camera options also — Lakhwinder Singh, Dec 08 '15 at 11:06

seems like you are using android.hardware.Camera along with surfaceview. But Camera class is no longer supported in API level above 21 see [this](http://developer.android.com/reference/android/hardware/camera2/package-summary.html). So you need to use the latest camera2 API. — Mahesh B ツ, Dec 08 '15 at 11:37

Have you tried one of these ? It seems like your camera service didn't work properly / camera may be used for another application.

Failed to connect to camera service

Use the web camera in the android emulator

I use MacOSX by the way. i just say that, it works on my machine. I sent installed tools and logs. Maybe it helps.

VD Configuration

Nexus 5, API 23 (Both Cameras are selected)

When i start the emulator, it gives warning in the log but at in the end it worked.

With Android API >= 23, you must ask for permission in code like:

int REQUEST_PERMISSION= 100;
int cameraPermission = this.checkSelfPermission(Manifest.permission.CAMERA);
if (android.os.Build.VERSION.SDK_INT >= 23) {
  if (cameraPermission != PackageManager.PERMISSION_GRANTED  ) {


      this.requestPermissions(
            new String[]{Manifest.permission.CAMERA },
            REQUEST_PERMISSION
    );
  }
}

Now ok to run.

You also have to add permissions in AndroidManifest.xml. See https://stackoverflow.com/questions/7829162/failed-to-connect-to-camera-service?noredirect=1&lq=1 – Eden Jan 19 '20 at 19:47

The solution is simple: You cannot run a camera when using a virtual machine unless you link the action of opening the VM camera to opening your webcam.

Starting with API 23 you need to request permissions at runtime. This was not the case in API <23 . For API <23 permissions in the manifest is enough.

This is an example from Android Developers :

Check for permission :

// Assume thisActivity is the current activity
int permissionCheck = ContextCompat.checkSelfPermission(thisActivity,
        Manifest.permission.WRITE_CALENDAR);

Request permission :

// Here, thisActivity is the current activity
if (ContextCompat.checkSelfPermission(thisActivity,
                Manifest.permission.READ_CONTACTS)
        != PackageManager.PERMISSION_GRANTED) {

    // Should we show an explanation?
    if (ActivityCompat.shouldShowRequestPermissionRationale(thisActivity,
            Manifest.permission.READ_CONTACTS)) {

        // Show an expanation to the user *asynchronously* -- don't block
        // this thread waiting for the user's response! After the user
        // sees the explanation, try again to request the permission.

    } else {

        // No explanation needed, we can request the permission.

        ActivityCompat.requestPermissions(thisActivity,
                new String[]{Manifest.permission.READ_CONTACTS},
                MY_PERMISSIONS_REQUEST_READ_CONTACTS);

        // MY_PERMISSIONS_REQUEST_READ_CONTACTS is an
        // app-defined int constant. The callback method gets the
        // result of the request.
    }
}

Request response :

@Override
public void onRequestPermissionsResult(int requestCode,
        String permissions[], int[] grantResults) {
    switch (requestCode) {
        case MY_PERMISSIONS_REQUEST_READ_CONTACTS: {
            // If request is cancelled, the result arrays are empty.
            if (grantResults.length > 0
                && grantResults[0] == PackageManager.PERMISSION_GRANTED) {

                // permission was granted, yay! Do the
                // contacts-related task you need to do.

   

     } else {

            // permission denied, boo! Disable the
            // functionality that depends on this permission.
        }
        return;
    }

    // other 'case' lines to check for other
    // permissions this app might request
}
}

If you don't handle like that way you can't use camera on API's >= 23

Not all permissions needs to be granted by the user but only dangerous permissions (Camera , Location , ) :

http://developer.android.com/guide/topics/security/permissions.html#normal-dangerous

Did you add the camera permissions to the manifest ? As Ravi Hari said ? You commented that you are using Android Studio on that answer but you still need to add it to the manifest in Android Studio.. — David, Dec 17 '15 at 10:30
That's the package .. Do you know what a android manifest is ? You can find it when you switch to Android View and then select app->manifests->AndroidManifest.xml — David, Dec 17 '15 at 10:46

Quoting developers.android.com:

Beginning in Android 6.0 (API level 23), users grant permissions to apps while the app is running, not when they install the app. This approach streamlines the app install process, since the user does not need to grant permissions when they install or update the app. It also gives the user more control over the app's functionality; for example, a user could choose to give a camera app access to the camera but not to the device location. The user can revoke the permissions at any time, by going to the app's Settings screen.

System permissions are divided into two categories, normal and dangerous:

Normal permissions do not directly risk the user's privacy. If your app lists a normal permission in its manifest, the system grants the
permission automatically.

Dangerous permissions can give the app access to the user's confidential data. If your app lists a normal permission in its
manifest, the system grants the permission automatically. If you list a dangerous permission, the user has to explicitly give approval to
your app.

So, I accomplished my task like as below:

For Checking permission I created a separate class as below:

public class MarshMallowPermission {

    public static final int RECORD_PERMISSION_REQUEST_CODE = 1;
    public static final int EXTERNAL_STORAGE_PERMISSION_REQUEST_CODE = 2;
    public static final int CAMERA_PERMISSION_REQUEST_CODE = 3;
    Activity activity;

    public MarshMallowPermission(Activity activity) {
        this.activity = activity;
    }

    public boolean checkPermissionForRecord(){
        int result = ContextCompat.checkSelfPermission(activity, Manifest.permission.RECORD_AUDIO);
        if (result == PackageManager.PERMISSION_GRANTED){
            return true;
        } else {
            return false;
        }
    }

    public boolean checkPermissionForExternalStorage(){
        int result = ContextCompat.checkSelfPermission(activity, Manifest.permission.WRITE_EXTERNAL_STORAGE);
        if (result == PackageManager.PERMISSION_GRANTED){
            return true;
        } else {
            return false;
        }
    }

    public boolean checkPermissionForCamera(){
        int result = ContextCompat.checkSelfPermission(activity, Manifest.permission.CAMERA);
        if (result == PackageManager.PERMISSION_GRANTED){
            return true;
        } else {
            return false;
        }
    }

    public void requestPermissionForRecord(){
        if (ActivityCompat.shouldShowRequestPermissionRationale(activity, Manifest.permission.RECORD_AUDIO)){
           Toast.makeText(activity, "Microphone permission needed for recording. Please allow in App Settings for additional functionality.", Toast.LENGTH_LONG).show();
        } else {
            ActivityCompat.requestPermissions(activity,new String[]{Manifest.permission.RECORD_AUDIO},RECORD_PERMISSION_REQUEST_CODE);
        }
    }

    public void requestPermissionForExternalStorage(){
        if (ActivityCompat.shouldShowRequestPermissionRationale(activity, Manifest.permission.WRITE_EXTERNAL_STORAGE)){
            Toast.makeText(activity, "External Storage permission needed. Please allow in App Settings for additional functionality.", Toast.LENGTH_LONG).show();
        } else {
            ActivityCompat.requestPermissions(activity,new String[]{Manifest.permission.WRITE_EXTERNAL_STORAGE},EXTERNAL_STORAGE_PERMISSION_REQUEST_CODE);
        }
    }

    public void requestPermissionForCamera(){
        if (ActivityCompat.shouldShowRequestPermissionRationale(activity, Manifest.permission.CAMERA)){
            Toast.makeText(activity, "Camera permission needed. Please allow in App Settings for additional functionality.", Toast.LENGTH_LONG).show();
        } else {
            ActivityCompat.requestPermissions(activity,new String[]{Manifest.permission.CAMERA},CAMERA_PERMISSION_REQUEST_CODE);
        }
    }
}

Then, for getting

...
MarshMallowPermission marshMallowPermission = new MarshMallowPermission(this);
...

public void getPhotoFromCamera() {

    if (!marshMallowPermission.checkPermissionForCamera()) {
