Native Camera for Android & iOS [Open Source]

Hello @yasirkula,
I'm running into a minor issue. If I record a video and my gallery contains no videos, then the video saves to my android gallery under the "camera" album and not the temporaryCachePath. Otherwise, RecordVideo() works normally.

 

Can you check Logcat to see if an error message is logged there?

 

Here are my logs. The highlighted one shows the video saving to my DCIM folder.

 

There may be a native error that can only be seen via Logcat. You can use e.g. this Unity package to see Logcat logs: https://docs.unity3d.com/Packages/com.unity.mobile.android-logcat@1.1/manual/index.html

 

My apologies. I'm still an android newbie. Here are all the errors since I started up my app. The gallery was initially empty. Then, I captured a video and checked the gallery twice.

 

Can you try replacing Plugins/NativeCamera/Android/NativeCamera.aar with the one inside the attached zip archive?

 

It works now. Thank you so much!

 

Glad to hear it!

 

Hello, overall love the product, works great, but I'd like to allow users to take several photos in a row and when it comes to 8th or 9th photo the app starts to slow down, on the log cat i see skipped frames and warning that too much work is put on a single core. Any tips to handle making several photos with this plugin?

Warnings starts to popup when I'm calling the TakePicture method, I pretty much used ur example code.

 

AFAIK, calling NativeCamera functions consecutively shouldn't be a problem. If you generate Textures along the way, perhaps the memory consumed by those Textures is causing problems? You can try commenting out the Texture generation part in your code and see if it makes and difference. I'd also recommend you to use Profiler with Development Build to see if it helps pinpoint the issue.

 

Hello, I have the following script that executes on Button click but the camera app is not launching. Thanks a lot in advance! I love your other plugins too

Code (CSharp):

1. using System.Collections;
2. using System.Collections.Generic;
3. using UnityEngine;
4.  
5.  
6. public class screen : MonoBehaviour
7. {
8. private bool isSharing = false;
9.  
10. public void ShareSocialMedia()
11. {
12.     isSharing = true;
13. }
14.  
15. void LateUpdate()
16. {
17.     if (isSharing == true)
18.     {
19.         isSharing = false;
20.  
21.         StartCoroutine(TakePicture(512));
22.     }
23. }
24.  
25. IEnumerator TakePicture( int maxSize )
26. {
27.     yield return new WaitForEndOfFrame();
28.     NativeCamera.RequestPermission();
29.     NativeCamera.Permission permission = NativeCamera.TakePicture( ( path ) =>
30.     {
31.         Debug.Log( "Image path: " + path );
32.         if( path != null )
33.         {
34.             // Create a Texture2D from the captured image
35.             Texture2D texture = NativeCamera.LoadImageAtPath( path, maxSize );
36.             if( texture == null )
37.             {
38.                 Debug.Log( "Couldn't load texture from " + path );
39.                 return;
40.             }
41.  
42.             // Assign texture to a temporary quad and destroy it after 5 seconds
43.             GameObject quad = GameObject.CreatePrimitive( PrimitiveType.Quad );
44.             quad.transform.position = Camera.main.transform.position + Camera.main.transform.forward * 2.5f;
45.             quad.transform.forward = Camera.main.transform.forward;
46.             quad.transform.localScale = new Vector3( 1f, texture.height / (float) texture.width, 1f );
47.          
48.             Material material = quad.GetComponent<Renderer>().material;
49.             if( !material.shader.isSupported ) // happens when Standard shader is not included in the build
50.                 material.shader = Shader.Find( "Legacy Shaders/Diffuse" );
51.  
52.             material.mainTexture = texture;
53.              
54.             Destroy( quad, 5f );
55.  
56.             // If a procedural texture is not destroyed manually,
57.             // it will only be freed after a scene change
58.             Destroy( texture, 5f );
59.         }
60.     }, maxSize );
61.  
62.     Debug.Log( "Permission result: " + permission );
63. }
64. }

 

Can you see any meaningful error messages in logcat?

 

I'm running into the same issue Immerse_Enterprise experienced back in December where it's always returning Permission.Denied after initially asking for permission on Google Pixel device.

Phone: Pixel 4a
Android: 10
Unity: 2019.1.14f1

Code (CSharp):

1.  
2. Debug.LogError("Before NativeCamera.CheckPermission");
3. NativeCamera.Permission cameraPermission = NativeCamera.CheckPermission();
4. Debug.LogError("After NativeCamera.CheckPermission");
5. Debug.LogError($"cameraPermission = {cameraPermission}");

Exception in Logcat:

Can you try disabling Minification and Managed Stripping Level?

 

I've disabled stripping (was previously low) and have no minification enabled but am experiencing the same issue

I've also tried the updated NativeCamera.arr from the post on May 16th and have the issue.

 

Does this solution help: https://github.com/yasirkula/UnityNativeGallery/issues/99#issuecomment-589767053

 

I've tried putting the tools tags in for storage and camera permissions but it seems to be something else in the manifest which I haven't narrowed down yet.

Putting Native Camera into a fresh project shows it's working just fine on my Pixel 4. There seems to be a conflict in the game project I'm working on though. I'll post what the issue was that I ran into when I find it!

-- Update --
Turns out it is fixed by adding a replace tag to a WRITE_EXTERNAL_STORAGE permission. The generated manifest had a maxApiVersion entry from another plugin that when removed fixes Native Camera. Thanks @yasirkula !

Code (csharp):

1.  
2. <uses-permission android:name="android.permission.WRITE_EXTERNAL_STORAGE" tools:node="replace" />

Hello,

I have a problem initializing NativeCamera. I downloaded the NativeCamera.unitypackage from Github and installed it to the regular way. The Plugin is in Assets/Plugins/NativeCamera.

I implemented a C# script based on the example provided on Github ( TakePicture(int maxSize) method).
But Unity throws

error CS0246: The type or namespace name 'NativeCamera' could not be found (are you missing a using directive or an assembly reference?)
error CS0103: The name 'NativeCamera' does not exist in the current context

When I move NativeCarmea.cs from the Plugin-Folder to my Script folder, it's fine in Editor but when I try to build a Android-Build, I get

error CS0246: The type or namespace name 'NativeCameraNamespace' could not be found (are you missing a using directive or an assembly reference?)

I use Unity 2019.4.3f1 on Win10 with VS Community 2019 v16.6.3.

Is there something I forgot to do ?

 

You are probably using Assembly Definition Files. You should add NativeCamera.Runtime.asmdef to your own Assembly Definition File's Referenced Assemblies list.

 

Thank you, yasirkula, works now !

 

thanks for your great asset, work well on my phone. I wonder is it possible to add some image object in the camera preview image before taking the picture.

 

Unfortunately not, customizing the camera UI/preview/feed isn't possible with NativeCamera.

 

This plugin is a great find and the support you provide is impressive! Thank you. I am needing to synchronize recording video along with gyro and timecode data. This plugin is working great to record video and I believe you are catching the Stop Recording event of the native recorder to return control back to the user. Would it be possible to add a Start Recording unity event so we could have a couple listeners get a callback? That is a slightly different design pattern than you use generally so a single async callback would also work. Any consideration or alternative ideas are welcome. I don't see many feature requests in this forum so I hope this isn't bad form. I just think this request is consistent with the overall scope and would really help my case.

 

When RecordVideo is called, NativeCamera launches the device's default camera app on Android and uses UIImagePickerController on iOS. Unfortunately, neither of these solutions have any StartedRecording/StoppedRecording callbacks. They return a result to NativeCamera only after user stops recording and confirms to send the recorded video back to Unity.

 

Wow that was fast. Thanks! Yes those APIs are limited. Well there might be a way to get a reasonable but not frame accurate approximation by watching the cache folder changes.

 

For the best results, you may want to use a plugin that renders the native camera feed inside Unity (i.e. handles the camera stuff in managed C# at runtime), instead of using the device's native camera app.

 

Is there a way to use the camera but without leaving the application (without having to access the camera application and have scaling problems)? something like using raw image directly?

 

Unfortunately NativeCamera doesn't have this feature :/

 

Should this plugin have any compatibility issues with ARFoundation? Sometimes our ARSession gets completely wiped after returning from NativeCamera.TakePicture(), but not always (mostly on iOS). We believe this is due to a race condition where ARSession is not getting the camera device back from NativeCamera.

Also, should NativeCamera.IsCameraBusy() always be returning false on Android, even when the camera is in use by the Asset itself? We were going to attempt to pause the ARSession (ARSession.enabled = false) and resume when the camera is available again, but it appears IsCameraBusy doesn't actually poll the state on Android (as a matter of fact, I should ask, how does this work on iOS exactly)?

We're going to attempt to delay unpausing the ARSession by a few frames (or seconds) and seeing it that remedies it, but we would like for an API to see if the camera resource is available.

 

IsCameraBusy() is only implemented in iOS, you are right. On iOS, it returns true while NativeCamera's camera window (UIImagePickerController, technically) is still visible. It doesn't really check if any other app/component is using the camera.

I think the idea of delaying ARSession by a few frames or seconds sounds promising. Since IsCameraBusy won't be useful in your case, you can start that delay inside the CameraCallback function.

 

Can you add APIs to check if the device resource is free? About to test a build with a delay.

 

I might but it is currently not a priority for me.

 

Hello there! Thank you for your plugin!
Tell me how I can rotate the resulting image 90 degrees to the right so that it is vertical.
Please give me the code if you can

 

You can't rotate an image with NativeCamera but you can use LoadImageAtPath to create a Texture2D from an image in correct orientation.

 

Code (CSharp):

1.  public void TakePicture(int maxSize)
2.     {
3. NativeCamera.Permission permission = NativeCamera.TakePicture((path) =>
4.         {
5. if (path != null)
6.             {
7. NativeGallery.GetImageProperties(path);
8. Texture2D texture = NativeCamera.LoadImageAtPath(path, maxSize);
9. if (texture == null)
10.                 {
11. Debug.Log("Couldn't load texture from " + path);
12. return;
13.                 }
14. Main.M.getImgProduct(path);
15.             }
16. }, maxSize);
17. }
18. public void getImgProduct(string path)
19.     {
20. Sprite sp = LoadNewSprite(path);
21. loadImg.GetComponent<Image>().sprite = sp;
22. productChangeParent.transform.GetChild(2).GetComponent<Image>().sprite = sp;
23. imgPath = path;
24.     }
25.  
26. public static Sprite LoadNewSprite(string FilePath, float PixelsPerUnit = 100.0f, SpriteMeshType spriteType = SpriteMeshType.FullRect)
27.     {
28. Texture2D SpriteTexture = LoadTexture(FilePath);
29. Sprite NewSprite = Sprite.Create(SpriteTexture, new Rect(0, 0, SpriteTexture.width, SpriteTexture.height), new Vector2(0, 0), PixelsPerUnit, 0, spriteType);
30.  
31. return NewSprite;
32.     }
33. public static Texture2D LoadTexture(string FilePath)
34.     {
35. Texture2D Tex2D;
36. byte[] FileData;
37.  
38. if (File.Exists(FilePath))
39.         {
40. FileData = File.ReadAllBytes(FilePath);
41. Tex2D = new Texture2D(2, 2); // Create new "empty" texture
42. if (Tex2D.LoadImage(FileData)) // Load the imagedata into the texture (size is set automatically)
43. return Tex2D; // If data = readable -> return texture
44.         }
45. return null; // Return null if load failed
46.     }
47.  

that's what I use, here's my code.
Thank you for your quick response!


P.S.
Oh, right. I don't use your function...

 

Even though you state that you don't use LoadImageAtPath, I can see it in your code. I don't understand, does it not load the image in correct orientation?

P.S. Nevermind, just saw that your main code is using Texture2D.LoadImage instead of LoadImageAtPath.

 

@Camad you should look into yasir's other plugin, ImageCropper. It has free rotation.

@yasirkula we're having some serious issues on iOS and AR Foundation. NativeCamera takes a long time to start coming from an ARSession (ARKit throws a camera-access error, before NativeCamera eventually gets camera access).

 

I haven't tried the plugin in an AR project. Perhaps NativeCamera and ARSession are both trying to access the camera at the same time. Can you manually disable the AR camera before using NativeCamera so that the camera is freed?

 

I have been using this plugin without the WRITE_EXTERNAL_STORAGE before but now it doesn't work without that tag. Has there been any change related to this?

 

It has always required WRITE_EXTERNAL_STORAGE. For example, here's the 2018-version of the native code: https://github.com/yasirkula/UnityNativeCamera/blob/6c4337071a2fb41193b2e6b21132a471f69bfcd7/JAR Source/NativeCamera.java#L78-L79

Perhaps the permission was added by another plugin in the past so you didn't notice it?

P.S. You can revert to older versions from here to see if any of the previous releases were working fine without WRITE_EXTERNAL_STORAGE.

 

Hello! Love this asset! I was wondering if there was a way to determine the length of the video the user created after they are done?

 

You can use

NativeCamera.GetVideoProperties(videoPath).duration

to get the video duration in milliseconds.

 

Hello,
can I use this to access the Time-of-Flight camera of my Samsung Galaxy S20+ ?
In Android Studio I do this to get the id of the ToF sensor:

Code (CSharp):

1.    private String getBackDepthCameraID() {
2.         try {
3.             for (String camera : cameraManager.getCameraIdList()) {
4.                 CameraCharacteristics chars = cameraManager.getCameraCharacteristics(camera);
5.                 final int[] capabilities = chars.get(CameraCharacteristics.REQUEST_AVAILABLE_CAPABILITIES);
6.                 boolean facingBack = chars.get(CameraCharacteristics.LENS_FACING) == CameraMetadata.LENS_FACING_BACK;
7.                 boolean depthCapable = false;
8.                 for (int capability : capabilities) {
9.                     boolean capable = capability == CameraMetadata.REQUEST_AVAILABLE_CAPABILITIES_DEPTH_OUTPUT;
10.   /*************/
11.     }

 

I'm not sure. I call Android's standard ACTION_VIDEO_CAPTURE and ACTION_IMAGE_CAPTURE intents and don't know what will happen in your case.

 

Boa tarde amigo parabéns pelo trabalho, bom eu sou novo aqui como eu poderia colocar este plugin em um botão para tirar foto? Se puder me dizer quais scripts tenho que anexar a camera ou ao canvas, agradeço desde ja

 

You can make the TakePicture function in the example code public and assign it to a button.

 

[QUOTE = "yasirkula, post: 6532547, membro: 56169"] Você pode tornar a função TakePicture no código de exemplo pública e atribuí-la a um botão. [/ QUOTE]
AMIGO OBRIGADO, você teria uma dica preciso que capturar um objeto com essa camera, pensei em criar um script quando clicar no botão abria uma cena, você acha que abriria a camera tambem?

 

I'm not sure what you mean by capturing an object with the camera. This plugin open's Android/iOS device's camera hardware and takes an image from real life. If that's what you want, then as I said, you could use the example code's TakePicture function. Simply add that function to your script.

 

Hello Yasirkula, i have been using your amazing plugin in my app in unity 2018, last week i donwloaded 2020 unity version but there is a lot of bugs and problems , so i started to make it from cero , so, the native camera is working, but wen i want to make an screenshot after taking the photo i dont get the capture saved on my phone galery, ive been using this code to take screenshot but in this newer version this does not working, could you help me please?

PD: i updated the native camera plugin

using System.Collections;
using System.Collections.Generic;
using UnityEngine;
using System.IO;
using UnityEngine.UI;


public class takeScrenshBton : MonoBehaviour
{

public void TakeAshot()
{
// yield return CaptureScreenshot();
Invoke("CaptureScreenshot", 0f);

}

public void CaptureScreenshot()
{
StartCoroutine(CaptureScreenshotCoroutine());

}

private IEnumerator CaptureScreenshotCoroutine()
{
// We should only read the screen buffer after rendering is complete
yield return new WaitForEndOfFrame();

// Create a texture the size of the screen, RGB24 format
int width = Screen.width;
int height = Screen.height;
Texture2D tex = new Texture2D(width, height, TextureFormat.RGB24, false);

// Read screen contents into the texture
tex.ReadPixels(new Rect(0, 0, width, height), 0, 0);
tex.Apply();

// Encode texture into PNG
byte[] bytes = tex.EncodeToPNG();
Object.Destroy(tex);


string timeStamp = System.DateTime.Now.ToString("dd-MM-yyyy-HH-mm-ss");
string filename = "Thepic_" + timeStamp + ".png";

string fileLocation = Path.Combine(Application.persistentDataPath, filename);
File.WriteAllBytes(fileLocation, bytes);

string myFolderLocation = "/storage/emulated/0/Photoapp/";

if (!Directory.Exists(myFolderLocation))

//if it doesn't, create it
Directory.CreateDirectory(myFolderLocation);

string myScreenshotLocation = myFolderLocation + filename;
System.IO.File.Move(fileLocation, myScreenshotLocation);

using (AndroidJavaClass jcUnityPlayer = new AndroidJavaClass("com.unity3d.player.UnityPlayer"))
using (AndroidJavaObject joActivity = jcUnityPlayer.GetStatic<AndroidJavaObject>("currentActivity"))
using (AndroidJavaObject joContext = joActivity.Call<AndroidJavaObject>("getApplicationContext"))
using (AndroidJavaClass jcMediaScannerConnection = new AndroidJavaClass("android.media.MediaScannerConnection"))
using (AndroidJavaClass jcEnvironment = new AndroidJavaClass("android.os.Environment"))
using (AndroidJavaObject joExDir = jcEnvironment.CallStatic<AndroidJavaObject>("getExternalStorageDirectory"))
{
jcMediaScannerConnection.CallStatic("scanFile", joContext, new string[] { myScreenshotLocation }, null, null);
}

}

 

I'd recommend you to use NativeGallery to save the image to Gallery. It should work.
