How use Java Camera in Background(into Service)?
in service at the moment I can only native camera connect.
Java Camera(CameraBridgeViewBase) need initialization with VIEW, like this:
mOpenCvCameraView = (CameraBridgeViewBase) findViewById(R.id.tutorial1_activity_java_surface_view);
If i understand well, you can try this:
Define JavaCameraView like you do but change the height to 0:
<org.opencv.android.JavaCameraView
android:id="@+id/HelloOpenCvView"
android:layout_width="fill_parent"
android:layout_height="0dp"
android:visibility="invisible"
opencv:camera_id="any"
opencv:show_fps="false" />
It just disapear the camera view but you can still work normaly. This is work for me.
I'm mot sure, that it works well on all devices. JavaCameraView adopts camera resolution to view size, so I'm not sure that camera would initialize correctly if View size is zero.
I dont really get the question 100%, but I assume you want to use the JavaCameraView from opencv?
Ive posted source code to use either NativeCameraView or JavaCameraView here:

JavaCameraView is inherited from Android View class. So it is a view and you cannot use it in Service directly. It uses standard android.hardware.Camera class, so you can re-implement the same behavior without view object.
