Turn your Android device webcam (Camera) , flash light

Question

Hello to all dear friends

I am Iranian. I am weak in English. The question text was translated by Google Translate.

The first question in the forum.

I'm making a game or app for Android with Unity.

At the same time I need to start my webcam device and flash light.

I can tell by the webcam into a texture.

 WebCamDevice[] devices;
 WebCamTexture texture;
  
 devices = WebCamTexture.devices;
  
 if (devices.Length == 2) {
 texture = new WebCamTexture (devices [1].name, 1024, 768, 100000000);
  
 texture.Play ();
  
 this.renderer.material.mainTexture = texture;
 }

You can also create a plug-in to Eclipse,

Turn your Android device with Flash light through it.

 AndroidJavaObject camera;
  
  AndroidJavaClass cameraClass = new AndroidJavaClass("android.hardware.Camera");
  
  int camID = 0;
  camera = cameraClass.CallStatic<AndroidJavaObject>("open", camID);
  
  if (camera != null){
  AndroidJavaObject cameraParameters = camera.Call<AndroidJavaObject>("getParameters");
  cameraParameters.Call("setFlashMode","torch");
  camera.Call("setParameters",cameraParameters);
  }

But now the problem is, I had the great test, I found a code that only allow access to the camera is turned off. If the code is used to take the first turning on the device Nvrflsh,

 camera = cameraClass.CallStatic<AndroidJavaObject>("open", camID);

The second code to turn on your webcam or camera is not running.

 texture.Play ();

And vice versa.

Now, dear friends help me. How do I do (webcam) and (flash light) on my Android device ????

Excuse me for disturbing text !

I am waiting for a response.

Hello again, To turn on your camera, you need to do that from your Android project. So Unity will just call the Android method that turn on your camera

In this example we have the method "launch".

Unity Code

 #if UNITY_ANDROID
             AndroidJavaClass androidJavaClass = new AndroidJavaClass ("com.unity3d.player.UnityPlayer");
             AndroidJavaObject androidJavaObject = androidJavaClass.GetStatic<AndroidJavaObject> ("currentActivity");
             androidJavaObject.Call ("launch");
             #endif

Generate your Android project from unity and add this method to your UnityPlayerNativeActivity.java

 public void Launch() {
         Intent takePictureIntent = new Intent($$anonymous$$ediaStore.ACTION_I$$anonymous$$AGE_CAPTURE);
         // Ensure that there's a camera activity to handle the intent
         if (takePictureIntent.resolveActivity(getPackage$$anonymous$$anager()) != null) {
             // Create the File where the photo should go
             File photoFile = null;
             try {
                 photoFile = createImageFile();
                 // Continue only if the File was successfully created
                 takePictureIntent.putExtra($$anonymous$$ediaStore.EXTRA_OUTPUT,    Uri.fromFile(photoFile));
                 startActivityForResult(takePictureIntent,TA$$anonymous$$E_PICTURE_REQUEST_CODE);
 
             } catch (IOException ex) {
                 // Error occurred while creating the File
 
             }
 
         }
     }

Finally, don't forget to allow your camera access from your Android$$anonymous$$anifest.xml :

 <uses-permission android:name="android.permission.CA$$anonymous$$ERA" />
 <uses-feature android:name="android.hardware.camera" />
 <uses-feature android:name="android.hardware.camera.autofocus" />

Thank you, kind friend

In this way you program your Android device like a camera will help to have a picture taken and stored somewhere in the track called Unity.

It is standard procedure that most of the methods used.

I thought I saw the way you've presented it is best to take photos of the facilities is higher.

So I am using the same method you.

Thank you very much my friend.

Hello again

I saw the review (Android camera app) to capture interesting.

I like to play in Unity camera or webcam is activated.

I do not want another program I use to take photos.

This way you just described above and Training (Android camera app) to run and open.

But it is not my intention.

I want the camera or webcam is displayed on my game, like my own example and example.

I want the camera flash light while running my webcam.

That is not the way to do this?

Unfortunately I can not speak French.

I would not use the code below in the Unity.

 WebCamDevice[] devices;
 WebCamTexture texture;
 devices = WebCamTexture.devices;
 if (devices.Length == 2) {
 texture = new WebCamTexture (devices [1].name, 1024, 768, 100000000);
 texture.Play ();
 this.renderer.material.mainTexture = texture;
 }

And the Now I want (camera flash light) torch on

I hope you understand

With WebCamTexture you can just take screenshot, I think that you can't manipulate camera's option with this object.

Have you checked out NatCam? It supports flash and many other features. And running the camera while flash is on is planned for the upcoming version.
