I am using Vuforia samples. So I am trying to start using front camera.
I am changing
vuforiaAppSession.startAR(CameraDevice.CAMERA_DIRECTION.CAMERA_DIRECTION_DEFAULT); to Front camera at ImageTargets.java inside Vuforia sample app. The result I am getting with front camera is just black screen.
Here is the error code:
VuforiaSamples E/ImageTargets: Unable to open camera device: 2 com.vuforia.samples.SampleApplication.SampleApplicationException: Unable to open camera device: 2 at com.vuforia.samples.SampleApplication.SampleApplicationSession.startCameraAndTrackers(SampleApplicationSession.java:153) at com.vuforia.samples.SampleApplication.SampleApplicationSession.access$900(SampleApplicationSession.java:31) at com.vuforia.samples.SampleApplication.SampleApplicationSession$StartVuforiaTask.doInBackground(SampleApplicationSession.java:623) at com.vuforia.samples.SampleApplication.SampleApplicationSession$StartVuforiaTask.doInBackground(SampleApplicationSession.java:604) at android.os.AsyncTask$2.call(AsyncTask.java:333) at java.util.concurrent.FutureTask.run(FutureTask.java:266) at android.os.AsyncTask$SerialExecutor$1.run(AsyncTask.java:245) at java.util.concurrent.ThreadPoolExecutor.runWorker(ThreadPoolExecutor.java:1162) at java.util.concurrent.ThreadPoolExecutor$Worker.run(ThreadPoolExecutor.java:636) at java.lang.Thread.run(Thread.java:764) Not able to find some more specific information.
