Answer : I wrestled with this problem a bit today, too. First, make sure that your permissions are set up correctly. Specifically, to record video, you'll want: <uses-feature android:name="android.hardware.camera.front" /> <uses-feature android:name="android.hardware.microphone"/> <uses-permission android:name="android.permission.CAMERA" /> <uses-permission android:name="android.permission.RECORD_AUDIO" /> <uses-permission android:name="android.permission.WRITE_EXTERNAL_STORAGE" /> Second, and this is the tricky part, this line from the tutorial does not work with the front-facing camera! mMediaRecorder.setProfile(CamcorderProfile.get(CamcorderProfile.QUALITY_HIGH)); That signature for CamcorderProfile.get() defaults to a profile for the back-facing camera: Returns the camcorder profile for the first back-facing camera on the device at the given quality level. If the device has n...

Answer : type url chrome://flags/#unsafely-treat-insecure-origin-as-secure Enter url in the textarea Choose Enabled in the select option Click image link bellow to see detail example Chrome blocks vulnerable features—including camera, location, microphone, etc. on non-secure sites. As of July 2018, with the release of Chrome 68, Chrome starts to mark all HTTP sites as "not secure." You have three options to unblock these features for your site: Treat 192.168.10.79 as secure origins by setting chrome://flags/#unsafely-treat-insecure-origin-as-secure . Origins must have their protocol specified, e.g., http://192.168.10.79 . Port forwarding your site address to localhost . Chrome treats localhost as secure origins. Set up a self-signed certificate for the server.

Answer : You can use the ARCamera.transform property to get the current transform of your camera. The following code is from Introducing ARKit at WWDC 2017 which you probably want to watch as an introduction. We are using the transform to place a node 10 cm in front of the camera. In Swift: var translation = matrix_identity_float4x4 translation.columns.3.z = -0.1 // Translate 10 cm in front of the camera node.simdTransform = matrix_multiply(currentFrame.camera.transform, translation) In Objective-C matrix_float4x4 translation = matrix_identity_float4x4; translation.columns[3][2] = -0.1; // Translate 10 cm in front of the camera node.simdTransform = matrix_multiply(currentFrame.camera.transform, translation)

Answer : Here's an example activity that will launch the camera app and then retrieve the image and display it. package edu.gvsu.cis.masl.camerademo; import android.app.Activity; import android.content.Intent; import android.graphics.Bitmap; import android.os.Bundle; import android.view.View; import android.widget.Button; import android.widget.ImageView; public class MyCameraActivity extends Activity { private static final int CAMERA_REQUEST = 1888; private ImageView imageView; private static final int MY_CAMERA_PERMISSION_CODE = 100; @Override public void onCreate(Bundle savedInstanceState) { super.onCreate(savedInstanceState); setContentView(R.layout.main); this.imageView = (ImageView)this.findViewById(R.id.imageView1); Button photoButton = (Button) this.findViewById(R.id.button1); photoButton.setOnClickListener(new View.OnClickListener() { @Override public void onClick(View v...
