【问题讨论】：
当然，你的模拟器没有摄像头，除非你允许它使用你电脑的摄像头。 有一个选项，在创建模拟器以使用后置摄像头和前置摄像头时，如果您使用的是android studio，那么您应该克隆您的设备，它会让您自定义设备规格，然后您也可以选择相机选项 我已经选择了那个选项 它在我的 Mac 上使用类似的模拟器运行：这是配置文件之间的区别drive.google.com/file/d/0B_3yQOBMz3jvVDJYdWJfaTcybFU/… 你的配置也在我的 MAC 上工作（我不得不删除皮肤。* 元素） 【参考方案1】：编辑
您尝试过其中一种吗？您的相机服务似乎无法正常工作/相机可能被用于其他应用程序。
Failed to connect to camera service
Use the web camera in the android emulator
顺便说一下，我使用 MacOSX。我只是说，它适用于我的机器。我发送了安装的工具和日志。也许它有帮助。
VD 配置
Nexus 5, API 23 (Both Cameras are selected)
当我启动模拟器时，它会在日志中发出警告，但最终它起作用了。

【讨论】：
【参考方案2】：对于 Android API >= 23，您必须在如下代码中请求权限：
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
);
现在可以运行了。
【讨论】：
您还必须在 AndroidManifest.xml 中添加权限。见***.com/questions/7829162/…【参考方案3】：解决方案很简单：在使用虚拟机时不能运行摄像头，除非将打开 VM 摄像头的操作与打开网络摄像头相关联。
【讨论】：
如何链接它们？在 bluestacks 中，它无需任何额外步骤即可工作【参考方案4】：从 API 23 开始，您需要在运行时请求权限。在 API
这是来自 Android 开发者的示例：
检查权限：
// Assume thisActivity is the current activity
int permissionCheck = ContextCompat.checkSelfPermission(thisActivity,
Manifest.permission.WRITE_CALENDAR);
请求权限：
// 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.
请求响应：
@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

如果你不这样处理，你就不能在 API 上使用相机 >= 23
并非所有权限都需要用户授予，只有危险权限（相机、位置、）：
http://developer.android.com/guide/topics/security/permissions.html#normal-dangerous
【讨论】：
您是否将相机权限添加到清单中？正如拉维哈里所说的那样？您评论说您在该答案上使用的是 Android Studio，但您仍需要将其添加到 Android Studio 中的清单中。 我正在使用 com.android.camera 就是那个包..你知道什么是android manifest吗？切换到Android View然后选择app->manifests->AndroidManifest.xml就可以找到【参考方案5】：引用developers.android.com：
从 Android 6.0（API 级别 23）开始，用户授予以下权限 应用程序运行时的应用程序，而不是在他们安装应用程序时。这 方法简化了应用程序安装过程，因为用户不 需要在安装或更新应用程序时授予权限。它也是 让用户更好地控制应用程序的功能；例如， 用户可以选择让相机应用程序访问相机，但不能 到设备位置。用户可以随时撤销权限 时间，通过转到应用程序的设置屏幕。
系统权限分为两类，普通权限和 危险：
普通权限不会直接危及用户的隐私。如果您的应用在其清单中列出了正常权限，则系统会授予 自动获得许可。 危险的权限可以让应用程序访问用户的机密数据。如果您的应用在其 manifest，系统自动授予权限。如果你列出 一个危险的权限，用户必须明确同意 你的应用。
所以，我完成了如下任务：
为了检查权限，我创建了一个单独的类，如下所示：
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);
那么，为了得到
...
MarshMallowPermission marshMallowPermission = new MarshMallowPermission(this);
...
public void getPhotoFromCamera()
if (!marshMallowPermission.checkPermissionForCamera())
marshMallowPermission.requestPermissionForCamera();
else
if (!marshMallowPermission.checkPermissionForExternalStorage())
marshMallowPermission.requestPermissionForExternalStorage();
else
Intent takePictureIntent = new Intent(MediaStore.ACTION_IMAGE_CAPTURE);
File mediaStorageDir = new File(
Environment.getExternalStorageDirectory()

);
if (!mediaStorageDir.exists())

);
takePictureIntent.putExtra(MediaStore.EXTRA_OUTPUT, Uri.fromFile(mediaFile));
startActivityForResult(takePictureIntent, PICK_FROM_CAMERA);
catch (IOException e)
e.printStackTrace();

【参考方案6】：可能是您的 PC 或 Mac 应该有工作相机或必须安装相机模拟..
