Native Camera for Android & iOS [Open Source]

Did you make the following change to Assets/Plugins/Android/AndroidManifest.xml: https://github.com/yasirkula/UnityNativeCamera#android-setup

It must be exactly Assets/Plugins/Android/AndroidManifest.xml, not Assets/Plugins/NativeCamera/Android/AndroidManifest.xml or something like that.

 

Hello there, first of all I want to thank you for this plugin.
I'm just having an issue: it looks like the plugin works only in development mode, if the build is not in development I have no reactions. I tested only on android until now.
I have the same issue also with your "Unity native gallery plugin", so I'm pretty sure I'm missing something, I'm a beginner in unity, but I honestly don't know what.
I would really appreciate any kind of support. Thank you

 

If you are using ProGuard, try adding the following line to ProGuard filters:

-keep class com.yasirkula.unity.* { *; }

. Otherwise, please debug your app with logcat to see if there are any error messages.

 

It looks like the issue is somehow related to build app directly from unity.
I tried to export the project and build the app using android Studio; I had to fix some issue but not directly related to your plugin and now everything works correctly whether I run or debug.

Maybe it could be something related to pause unity engine because when I click on button to open camera I have this messages:
W/Unity: Timeout while trying to pause the Unity Engine.
D/ViewRootImpl@9fcf3c2[UnityPlayerActivity]: MSG_WINDOW_FOCUS_CHANGED 0

 

The timeout message is expected with NativeCamera, so the issue should be something else. Do you see any other error messages after clicking the button to open the camera? Maybe something like "Content provider couldn't be found"?

 

Ok, so this is the issue:

Is Proguard selected/enabled in Player Settings-Minify? If so, you need to add

-keep class com.yasirkula.unity.* { *; }

to the Proguard filters.

 

It was because of Proguard. Sorry if I didn't check before but I had no idea what is it and where to find it.
Thank you so much!

 

Hi, thank you for taking the time to develop and share this asset.

I'm wondering if there is any way to have the front facing camera active when calling TakePicture(). It used to be possible in an earlier version using SetDefaultCamera(), but it looks like that's been removed.

Thankyou !

 

NativeCamera did not include SetDefaultCamera in earlier versions. Did you perhaps confuse it with another camera plugin?

P.S. Currently, NativeCamera doesn't support opening the front facing camera by default.

 

It definitely is your plugin, but since it is a legacy project I inherited, my guess is that it was probably modified by somebody long gone.
Sorry for bothering you, then !

 

How do we actually change the path? I can't seem to figure it out with the sample code. Also not sure whats wrong but after I take a picture the rectangle stays pink. No errors are thrown in debug, it runs smoothly, there is just a small pink rectangle that is displayed on the screen for about 3 seconds. And yes, I updated the Android Manifest
Here is a screenshot of the debug when running the sample code on my phone

 

@joesziveri Sorry to hear about the pink rectangle issue. I haven't encountered such an issue myself and I currently have no idea why it would happen. If you downloaded the asset from Asset Store, can you also try importing it from the GitHub repository and see if the issue persists?

BTW, you can't change the path of the captured image. It is always saved at the same path; you should instead move it to the desired location in your code.

 

Howdy, I did some researching and it seems the purple square had something to do with the shaders being applied in the sample code. Instead of using the temporary quad, I just added a UI Image and set the texture of that instead and it worked perfectly. Thanks for the quick reply!

 

Heya, we've hit a snag with using the nativecamera on iphone 8's - seems to work fine on 6 and 10's. Is there something that we're missing that needs to be applied?

 

Not that I know of. Are there any error messages or anything that could help me point out the issue?

 

Nothing of the sort - one of testers with an Iphone 8 clicked to request the nativecamera - it flew past the method without opening the cam, as if ios ignored it - or didn't have permission. alas no more information found at this point.

 

Is it possible that they'd denied the camera permission at first attempt? Permission dialog is only shown once after the app is installed. If permission is denied, user has to give permission from the Settings app.

 

I'll give that a shot - thanks!

 

Great plugin- but I'm having trouble getting the the texture to look correct. I'm simply passing the texture to another function and setting a texture that is the max and width of the screen to the recently taken picture. The picture looks to be super zoomed in, and is a blocked color. Here is the code in that function:

if (!Application.isEditor){screenImage.GetComponent<Image>().sprite = Sprite.Create(passedTexture, new Rect(0,0,passedTexture.width,passedTexture.height), new Vector2(0.5f, 0.5f));}

 

Maybe the Image component has a gray tint color and/or is bigger than the screen? Please make sure that the Image's Color property is opaque white and enable Preserve Aspect to see if anything changes. If that doesn't work, I don't really have any ideas because the texture comes from the native camera app and is not modified by NativeCamera.

 

Thanks for the reply. The sprite that is inheriting the new texture is definitely not the problem. I seem to be unable to get the newly taken picture's texture to display properly. I'm using an iPhone 6s on 10.3.3- seen any problems with that configuration? Thanks!

 

Is it also the same when you assign the texture to a RawImage object, i.e. not use an Image component and sprites.

 

Is there a way to get texture to apply to RawImage in UI element for preview?

 

You can use the NativeCamera.LoadImageAtPath function to load the image into a Texture2D and then assign it to a RawImage. If you are asking about a live camera feed, then it is not possible.

 

I got this asset to work fine on iOS, but on Android I get a crash after taking a second photo. The crash occurs right after the camera activity closes. Any idea how to fix this?

 

Are there any error messages in logcat? Can you also add some Debug.Log's to your code to pinpoint the line which causes the crash?

 

Hello, I attached a logcat.
This line was logged right before I called "02-16 10:30:57.101 14823 14873 V ABOT : OnTakePhotoClick"

The following lines are logged from C# after taking the photo
02-16 10:31:07.876 14823 14873 V ABOT : OnApplicationPause False
02-16 10:31:07.879 14823 14873 V ABOT : pause_time 0.172646983333333
02-16 10:31:07.908 14823 14873 V ABOT : Image path: /data/user/0/com.wingboat.AllowanceBot/cache/IMG_camera.jpg

Then I see this line in the log
02-16 10:31:11.281 776 6073 I ActivityManager: Process com.wingboat.AllowanceBot (pid 14823) has died: fore TOP

Can you see anything in my log that would help me get past this problem?

Btw, I'm not getting Debug.Log in the logcat output anymore. I had to add a native logging function to log the lines above. Do you know how to make Debug.Log output appear in logcat?

Thank you for your help!

 

Honestly, I can't see anything useful in logcat. I've googled "has died: fore TOP" but couldn't find any useful information there, either. It might help if you can find the problematic line by inserting Debug.Log's to every single line. I can always see Debug.Log messages if I use Android Studio's logcat window or launch "adb logcat -s Unity" command in command line (cmd).

 

hello, I have a problem: When I open the camera(IOS) but want to go back so i clicked candel but the callback(CameraCallBack()) will called once Each frame (path=null) and we can not do anything in APP,
The device is iphoneXR,Do you have any good ideas? Thank you vary much!

 

thank you!I have solved the problem

 

hello , i need help with native camera pulgin want to store clicked image directly in my phone gallery not in temp cache.can anyone help me with this ?

 

You can use NativeGallery.SaveImageToGallery for that.

 

hey, @yasirkula thanks for instant reply and suggestion. i am using NativeGallery.SaveImageToGallery like this with native camera script but... getting the following error in android console.


ArgumentException: Texture '' is not readable, the texture memory can not be accessed from scripts. You can make the texture readable in the Texture Import Settings.
at (wrapper managed-to-native) UnityEngine.ImageConversion.EncodeToPNG(UnityEngine.Texture2D)
at NativeGallery.GetTextureBytes (UnityEngine.Texture2D texture, System.Boolean isJpeg) [0x00002] in D:\Unity pro\Puzzle Game\Assets\Plugins\NativeGallery\NativeGallery.cs:452
at NativeGallery.SaveImageToGallery (UnityEngine.Texture2D image, System.String album, System.String filenameFormatted, NativeGallery+MediaSaveCallback callback) [0x00058] in D:\Unity pro\Puzzle Game\Assets\Plugins\NativeGallery\NativeGallery.cs:234

with this code :-

Code (CSharp):

1.  private void TakePicture(int maxSize)
2.     {
3.         NativeCamera.Permission permission = NativeCamera.TakePicture((path) =>
4.         {
5.             Debug.Log("Image path: " + path);
6.  
7.             if (path != null)
8.             {
9.                 Texture2D texture = NativeCamera.LoadImageAtPath(path, maxSize);
10.                 NativeGallery.SaveImageToGallery(texture, "GalleryTest", "My img {0}.png");
11.     }
12.         }, maxSize);
13.  
14.         Debug.Log("Permission result: " + permission);
15.     }

 

Try replacing lines 9 and 10 with this:

NativeGallery.SaveImageToGallery(path, "GalleryTest", "My img {0}.png");

 

hey, @yasirkula thanks man, replacing path did the job. Thanks again

 

Hey bro @yasirkula im having an issue with the camera, when the native camera lounches if i dont take a picture and if i press the "Back button" of my phone the app crashes, how can i configure that button? i would like to code it if i press the back button reset the scene

 

Having issues recording a video on Android.
I copied the sample code from the GitHub readme, but the logs just show:

Code (csharp):

1. Permission result: Granted
2. Image path:
3. Permission result: Granted
4. Video path:

 

Hey, thanks for your plugin, it's awesome!
I'd like to know if there is a way to select either video or picture from the native camera application?
Currently, I only seem to be able to select Picture or Video before launching the native camera application.

 

@zelmax Pressing back button isn't supposed to crash the app. Does the app crash entirely and not restart afterwards or does it simply restart after pressing the back button? If it is the latter, then it might be a low memory (RAM) issue. On which Android/iOS version does this issue occur? Is this behaviour persistent across different devices/emulators?

@unity_cTq6CR9L2kwxAw Honestly, this is the first time I see this issue. Assuming that your device has a camera and a camera application (Android's preinstalled Camera app works), this is unexpected. Can you replicate the issue on other devices?

@Toni_Doublet Maybe NativeGallery will work for you?

 

@yasirkula I mean , when i start the camera and I don't take a picture, simply press the back button of my phone , the camera close and my raw image get blank / white, I would like that, when I press the back button of my phone the scene restart it's possible? I'm using Android 5.1.1

 

Inside the callback function of NativeCamera, you can check if string.IsNullOrEmpty(path) is true. If so, you can restart the scene via SceneManager.LoadScene.

 

Thanks a lot bro , it works

 

@yasirkula, unfortunately the NativeGallery does not help for this... My issue is that I can't switch with from picture to video with the NativeCamera plugin at record time.
I attached a screenshot that shows my native camera application switch system.
Thanks a lot!

 

Why would you want to switch between photo and video? There are separate functions for each functionality (TakePicture and RecordVideo) and in general, you would need the user to either take a picture or record a video for a specific task.

 

@yasirkula, is there anything special I need to have done with permissions? I'm pretty sure I followed your setup instructions fully, but when I press the record side of the screen, no permissions dialog comes up yet the logs say permission granted and then returns a null path

The same issue is on both my android devices, which have perfectly working cameras otherwise.

(ps i was @unity_cTq6CR9L2kwxAw)

 

Does this issue also occur on a fresh new project with the example code? I can't think of any reasons for this behaviour.

 

Hey @yasirkula,
I have used your package in my project. An excellent and needed utility.
But I do have a concern/question that needs your attention.
The game crashes after I use the Native Camera TakePicture and LoadImageAtPath a few times.
I am assuming Android closes the game for some memory constraint.
Do I need to call

Code (CSharp):

1. Resources.UnloadUnusedAssets ()

after loading image from path?
Or is there a different way to prevent Android from closing the game in the background while taking a picture.
Thanks in advance and thank you again for keeping the plugin Open Source.
Regards,
Hitarth

 

If you don't specify a sufficiently small maxSize in LoadImageAtPath, created textures may consume a lot of memory because they are not compressed in any way. And if you keep creating new textures without destroying the previous unused ones (via Destroy), then these textures can quickly fill up the entire free memory on the mobile device and lead to a crash.

 

I replace references of the images that are loaded. So I expect the GC to collect and free memory.

The images loaded are not even kept as a reference in the scene.

Here is the code for that.

Code (CSharp):

1. //First Click image and store image path
2. public void Clickselfie ( int nextState = (int)UIStates.ConfirmSelfie )
3. {
4.     this.nextState = (UIStates)nextState;
5.     NativeCamera.TakePicture ( ReceiveSelfiePath );
6. }
7.  

And then later.

Code (CSharp):

1. public void LoadNewImageForEditing ()
2. {
3.     Destroy ( photo );
4.     photo = NativeCamera.LoadImageAtPath ( PlayerPrefs.GetString ( "selfiePath" ), markTextureNonReadable: false, generateMipmaps: false );
5.     float aspect = photo.width / (float)photo.height;
6.  
7.     TextureScale.Bilinear ( photo, Mathf.FloorToInt ( 1280 * aspect ), 1280 );
8.     photo.Apply ();
9.  
10.     photoImage.sprite = Sprite.Create ( photo, new Rect ( 0, 0, photo.width, photo.height ), Vector2.one * 0.5f );
11.     photoImage.preserveAspect = false;
12.     photoImage.rectTransform.sizeDelta = new Vector2 ( Mathf.FloorToInt ( 1024 * aspect ), 1024 );
13.     photoImage.rectTransform.anchoredPosition = Vector2.zero;
14.     result = new Texture2D ( result.width, result.height, TextureFormat.RGB24, false );
15.  
16.     Resources.UnloadUnusedAssets ();
17. }

My concern is that while I am taking a picture, the game gets a soft close by the OS.
I have checked the log a few times but i don't get an error from the app about a close.
