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

An error occurred while connecting to camera 0: Status(-8, EX_SERVICE_SPECIFIC): '1: validateClientPermissionsLocked:1165: Caller ... (PID 10153, UID 6049) cannot open camera "0" without camera permission'
I am attempting to get a camera working using this code我正在尝试使用此代码让相机工作
public static Camera getCameraInstance(){
Camera c = null;
try {
c = Camera.open();
} catch (Exception e) {
Log.e("getCameraInstance", "exception", e);
}
return c; // returns null if camera is unavailable
}
How do I get this camera working?如何让这台相机工作?
Need to enable permissions at runtime.需要在运行时启用权限。 The above error is outputted when the 0 indexed camera does not have permissions.
当索引为0的相机没有权限时,输出上述错误。 Adding permissions to the manifest is not what enables it on the phone... the below code will.
向清单添加权限并不是在手机上启用它的原因......下面的代码将。
public static void checkCameraPermissions(Context context){
if (ContextCompat.checkSelfPermission(context, Manifest.permission.CAMERA)
!= PackageManager.PERMISSION_GRANTED)
{
// Permission is not granted
Log.d("checkCameraPermissions", "No Camera Permissions");
ActivityCompat.requestPermissions((Activity) context,
new String[] { Manifest.permission.CAMERA },
100);
}
}
