Native Camera for Android & iOS [Open Source]

Hi

I'm using Native Camera plugin. Everything is ok when I record a video. But when I'm takeing picture there is popup information "No memory space". Max image size is set to 512. After takeing photo path to the image is null. I have privileges to camera and storage. What can cause the problem?

My device is HMT1 (RealWear)

 

Is your internal storage nearly full? Maybe the camera app internally decides to save the recorded video to SD card but save the photo to internal storage and can't find enough space in internal storage.

 

I have 10,1GB free and no SD card installed.

 

I wish I could help but NativeCamera simply starts the native camera app and leaves all the implementation details to that app. The "No memory space" error isn't directly generated by NativeCamera and I'm not sure how this issue can be resolved.

P.S. This is the first time I'm encountering this issue in my plugins.

 

I tried to make a photo outside application and everything is ok. I've also tried to make photo from application (using NativeCamera) on my android phone and everything is ok. Problem exists only on HMT1 (RealWear)

 

I understand but even googling "No memory space" doesn't really provide any useful info to me. I don't know where to look to resolve this issue with just the information I have.

I have the following errors, can you help with this

 

There is an error for the NativeCamera, TakePicture, RecordVideo,

 

This is relating to your instructions via this link https://forum.unity.com/threads/native-camera-for-android-ios-open-source.529560/page-3#post-4776890

 

In your script, you have 2 Updates, 2 TakePictures and 2 RecordVideos. Probably a copy&paste mistake. Removing one copy of each function from the script should resolve the issue.

 

I can't get this plugin to work
I have an app that is able to pick the image from android, upload it to FB and created separate scene for your plugin.
Basically only button back to main scene and button "make photo" with function from your github attached.
I click the button and nothing happens. Will greatly appreciate any help.

This is my code:

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

public class NativeCameraMakePhotoScript : MonoBehaviour
{

[SerializeField]
Button makePhotoButton;

[SerializeField]
Button backButton;


void Start()
{
makePhotoButton.onClick.AddListener(delegate{TakePicture(1024);});
backButton.onClick.AddListener(BackToMainScene);
}

void Update()
{
if( NativeCamera.IsCameraBusy() )
return;
}

private void TakePicture( int maxSize )
{
NativeCamera.Permission permission = NativeCamera.TakePicture( ( path ) =>
{
Debug.Log( "Image path: " + path );
if( path != null )
{
// Create a Texture2D from the captured image
Texture2D texture = NativeCamera.LoadImageAtPath( path, maxSize );
if( texture == null )
{
Debug.Log( "Couldn't load texture from " + path );
return;
}

// Assign texture to a temporary quad and destroy it after 5 seconds
GameObject quad = GameObject.CreatePrimitive( PrimitiveType.Quad );
quad.transform.position = Camera.main.transform.position + Camera.main.transform.forward * 2.5f;
quad.transform.forward = Camera.main.transform.forward;
quad.transform.localScale = new Vector3( 1f, texture.height / (float) texture.width, 1f );
Material material = quad.GetComponent<Renderer>().material;
if( !material.shader.isSupported ) // happens when Standard shader is not included in the build
material.shader = Shader.Find( "Legacy Shaders/Diffuse" );

material.mainTexture = texture;
Destroy( quad, 5f );

// If a procedural texture is not destroyed manually,
// it will only be freed after a scene change
Destroy( texture, 5f );
}
}, maxSize );

Debug.Log( "Permission result: " + permission );
}


public void BackToMainScene(){
SceneManager.LoadSceneAsync("SampleScene");
}

}

 

Please make sure that you've completed these steps:

- set Write Permission to External (SDCard) in Player Settings
- (Android) add the provider to your AndroidManifest.xml: https://github.com/yasirkula/UnityNativeCamera/#android-setup
- if you are using ProGuard, make sure to make an exception for the plugin's classes: https://github.com/yasirkula/UnityNativeCamera/#faq

I'd also recommend you to check logcat/Xcode console for any meaningful error messages.

P.S. You don't need the Update function in your script.

 

First of all, thank you for the replay. I did all those steps.
Maybe I will just write what I did step by step, maybe I did a mistake and its my fault: Created new project.
Added Android manifest (catalogue Plugins/Android), wrote the code above, changed the write permissions, checked if it works in unity -> I can see the response in the console: it shows me "Path" and "Permission: Granted".

 

Are you testing on the Unity Editor or on a device? While testing on an Android device, check out the Logcat logs, as well. Some important logs may show up in Logcat only.

 

I successfuly used nativecamera to take a photo and render it on a raw image and now it remains on the screen, but now I want to move the rendered image to another scene. How can I do that?

 

I happen to have an avatar placed into the scene from taking a picture with a camera, on the same scene I can select the player I want. Once I click the confirm button the new player gets loaded into the next scene successfully, but I am unable to make the avatar move into the new scene as well. How do I make the avatar move alongside the selected player into the next scene after clicking the confirm button? I already modified my camera script to store the avatar image permanently on the screen, aside from this I am unable to move the image into the scene with the selected player. I am pretty new to unity so I am kind of lost

My script for moving the character below

using System.Collections;
using UnityEngine.SceneManagement;

public class CharacterSelection : MonoBehaviour
{
private int index;
private GameObject[] characterList;

private void Start()
{
index = PlayerPrefs.GetInt("ChracterSelected");
characterList = new GameObject[transform.childCount];

//fill the array with our models
for(int i = 0; i < transform.childCount; i++)

characterList = transform.GetChild(i).gameObject;
// we toggle off their renderer
foreach (GameObject go in characterList)
go.SetActive(false);

// we toggle on the selected character
if (characterList[index])
characterList[index].SetActive(true);


}


MY SCRIPT FOR storing the photo permanently on the screen which works

using UnityEngine.UI;

public class takePhoto : MonoBehaviour

{
public RawImage photoTaken;

public void TakePictureButton()
{
TakePicture(512);
}

private void TakePicture(int maxSize)
{
NativeCamera.Permission permission = NativeCamera.TakePicture((path) =>
{
Debug.Log("Image path: " + path);
if (path != null)
{
// Create a Texture2D from the captured image
Texture2D texture = NativeCamera.LoadImageAtPath(path, maxSize);
if (texture == null)
{
Debug.Log("Couldn't load texture from " + path);
return;
}

photoTaken.texture = texture;
photoTaken.gameObject.SetActive(true);



}
}, maxSize);

Debug.Log("Permission result: " + permission);
}

}




public void ToggleLeft()
{
// Toggle of the current model
characterList[index].SetActive(false);
index--; //index -=1; index=index -1;
if (index < 0)
index = characterList.Length - 1;

// Toggle on the new model
characterList[index].SetActive(true);
}

public void ToggleRight()
{
// Toggle of the current model
characterList[index].SetActive(false);

index++; //index -=1; index=index -1;
if (index == characterList.Length)
index = 0;

// Toggle on the new model
characterList[index].SetActive(true);

}

public void confirm()
{
PlayerPrefs.SetInt("ChracterSelected", index);
SceneManager.LoadScene("RoleOutput");
}
}

 

The easiest solution would be to store the image in a

public static Texture2D Avatar { get; private set; }

property inside the takePhoto class. After adding this property to the class, you can simply say

Avatar = texture;

before calling

photoTaken.texture = texture;

. Then, from any scene, you can access this image via

photoTaken.Avatar

and assign it to a RawImage in that particular scene.

 

i change in androidmanifest.xml

but my app cant installed

help

 

Don't change

android:name

, change only

android:authorities

.

 

thanks its work

can this plugin image from folder path ??
like browse file

 

Thanks for your ResponseAccording to your response "Then, from any scene, you can access this image via photoTaken.Avatar and assign it to a RawImage in that particular scene."

Is this going to be under a different script or the same script I use to store the photo on the screen.

This is regarding to your response "https://forum.unity.com/threads/native-camera-for-android-ios-open-source.529560/page-4#post-4822031"

 

@eijie Please see NativeGallery and SimpleFileBrowser.
@Seve2 You can access

public static

members from any script on any scene.

 

Hi Yasirkula,
thanks for making this great asset for free! I was able to make it work within minutes. One Question that came already to my mind is the language the nativeCamera is using. When the CameraView is open everything is in English. "Retake", "Use Photo" .. Is it possible to use the device language for these?

Also: is it possible to make more than one picture at import them at once? I'm thinking of the behavior of whatsapp when sending multiple pictures.


Thanks & Regards,
Eric

 

The native camera app shows those labels, so I'm guessing that they're affected by the device's language settings. If not, I don't think I've any control over them since googling

ACTION_IMAGE_CAPTURE "localization"

yields no relevant results.

You can call NativeCamera.TakePicture again in the CameraCallback, so the camera will open again right after an image is captured. This might not work on iOS at the moment but I'll fix it soon.

 

hello,
first of all thank you for making this free, but i'm running into a problem:
when going into the camera and taking a picture, or when going into camera and pressing back button, the app restarts
(if it helps) i used native gallery asset to load an image from gallery and it doesn't restart

 

Is it happening on a very old device? Opening the camera increases the memory usage and if OS runs out of memory, it starts killing background activities, including Unity. I've seen this behaviour occasionally on Galaxy S3 but never on newer and more powerful devices. I'm afraid it is out of my hands.

 

I am having an issue like this too. Do you know why its not capturing image?

 

Does this help: https://forum.unity.com/threads/native-camera-for-android-ios-open-source.529560/page-3#post-4372456

If not, can you try the example code in an empty project and see if it works like that? Don't forget to add the provider to your AndroidManifest.

 

Hi, I installed your plugin in a separate project and it worked like a charm (therefor I immediately changed to 5 stars). I think I know why I have a problem in my main project - I'm using also another plugin and I assume their manifests are conflicting? (Don't know much about Android so its my assumption). If you could help me with this I would be extremely grateful. Is it possible to merge both manifests? The second one looks like this:

<?xml version="1.0" encoding="utf-8"?>
<manifest xmlns:android="http://schemas.android.com/apk/res/android"
package="com.kakeragames.unimgpicker">
<application>
</application>
</manifest>

EDIT: I created empty project and included both plugins. Worked like a charm. No idea why it doesn't work in my main project. Is it possible that I have a conflict with Firebase or Playfab? Since the firebase files are in the Android catalogue before I put the Android Manifest there, could they create a conflict?

 

If your main project uses ProGuard minification in Player Settings, you should add the following line to the ProGuard filters:

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

. Let me know if your project uses a minification other than None and ProGuard.

Otherwise, assuming that both projects have Write Permission set to "External (SDCard)" and have the same AndroidManifest.xml files at exactly the same places, this issue shouldn't occur.

 

I created empty project and included both plugins (Native Camera and UnimgPicker). Worked like a charm. No idea why it doesn't work in my main project. Is it possible that I have a conflict with Firebase or Playfab? Since the Firebase files are in the Android catalogue before I put the Android Manifest there, could they create a conflict?
When the Android Manifest file is not there, build and run works perfect. When I put it in the Android catalogue (which already contains Firebase) the app builds successfully, but won't install I'm a bit desperate...

 

Was able to track the issue:
After adding your AndroidManifest i get this:
Failure [INSTALL_FAILED_CONFLICTING_PROVIDER]

I think it solves it.... I feel stupid now

 

Try changing the value of your

android:authorities

string.

 

Thank you, already did it, works like a charm Anyway, I have last question haha Sorry for bothering you so much
I wanted to ask you about the best way to save the photo. I mean I have the code to save it on Android but it doesn't work in this case.


private void TakePicture( int maxSize )
{
NativeCamera.Permission permission = NativeCamera.TakePicture( ( path ) =>
{
Debug.Log( "Image path: " + path );
if( path != null )
{
// Create a Texture2D from the captured image
cacheTexture = NativeCamera.LoadImageAtPath( path, maxSize );

if( cacheTexture == null )
{
Debug.Log( "Couldn't load texture from " + path );
return;
}


SaveImageToGallery(cacheTexture, "test", "test");

}
}, maxSize );

Debug.Log( "Permission result: " + permission );

}


public string SaveImageToGallery(Texture2D texture2D, string title, string description)
{
using (var mediaClass = new AndroidJavaClass(MediaStoreImagesMediaClass))
{
using (var cr = Activity.Call<AndroidJavaObject>("getContentResolver"))
{
var image = Texture2DToAndroidBitmap(texture2D);
var imageUrl = mediaClass.CallStatic<string>("insertImage", cr, image, title, description);
return imageUrl;
}
}
}

public AndroidJavaObject Texture2DToAndroidBitmap(Texture2D texture2D)
{
byte[] encoded = texture2D.EncodeToPNG();
using (var bf = new AndroidJavaClass("android.graphics.BitmapFactory"))
{
return bf.CallStatic<AndroidJavaObject>("decodeByteArray", encoded, 0, encoded.Length);
}
}

 

I also tried doing simply:

imgBytes = texture.EncodeToPNG();
var dirPath = Application.persistentDataPath;
File.WriteAllBytes(dirPath + "Image" + ".png", imgBytes);

But it saved empty png

 

I managed to solve it by writing this function (where _imgPath = path). Hope it will help someone in the future :

public void QuickSave(){
if(!String.IsNullOrEmpty(_imgPath)) {
imgBytes = File.ReadAllBytes(_imgPath);
cacheTexture = new Texture2D(2, 2);
cacheTexture.LoadImage(imgBytes);
SaveImageToGallery(cacheTexture, "testCache", "test");
}
}
Anyway, this solution is pretty simple and clean, but a bit slow

 

Or, you can simply copy the image at "path" to wherever you want via File.Copy. Nothing else can beat its speed. And you should use Path.Combine(dirPath, "Image.png") to create paths, otherwise you'll have to handle / and \ characters manually.

 

Thank you, I will definitely try this!

 

Works great with Application.persistentpath but I have no idea how to copy it to
android.provider.MediaStore$Images$Media

 

Another thing that I can't wrap my mind around is it seems to be impossible to adjust the aspect ratio of the image to the texture.
Works in every single scenario besides this:

private void TakePicture( int maxSize )
{
NativeCamera.Permission permission = NativeCamera.TakePicture( ( path ) =>
{
Debug.Log( "Image path: " + path );

_imgPath = path;

if( path != null )
{
// Create a Texture2D from the captured image
Texture2D texture = NativeCamera.LoadImageAtPath( path, maxSize );

if( cacheTexture == null )
{
Debug.Log( "Couldn't load texture from " + path );
return;
}


//Getting the aspect ratio
float textH = texture.height;
float textW = texture.width;
Debug.Log("H: " + textH + " W: " + textW);

float aspectRation = textH > textW ? textH / textW : textW / textH;

output.GetComponent<AspectRatioFitter>().aspectRatio = aspectRation;
output.texture = texture;

}
}, maxSize );

Debug.Log( "Permission result: " + permission );

}

 

You'll need to do:

float aspectRation = textH > textW ? (float) textH / textW : (float) textW / textH;

Also check out Native Gallery to easily save your images to Gallery: https://forum.unity.com/threads/native-gallery-for-android-ios-open-source.519619/

 

Thank you for the response, unfortunately it didn't work either

 

Hi! I was testing a little bit with the Quality parameter of the RecordVideo. It doesn't seem to change much, and the size of the video stays pretty much the same. Is this something that the device camera settings can override?

 

Some Android camera apps (even built-in camera apps) may not respect the parameters NativeCamera sends to them like quality, video length and etc. It is out of my control, unfortunately. So you shouldn't 100% rely on them.

 

Hi yasirkula!
First of, thank you for all of your work not just this one, all are very useful!

I have few questions regarding NativeCamera:

- Is there a way to take more than just one photo when Camera app is opened? Because, after one photo is shot, there is "retry" and "ok". It would be great if there is possibility to shot photos as user want, then save them (example, with your NativeGallery to gallery) and when user is done with shooting there is a button to go back to Unity app (I know its impossible to put overlay on Camera app, but back button is enough for now).

- I tried your example script with your NativeGallery and in Android build (I didn't tried iOS build yet) images are rotated 90 degrees counterclockwise, is there are way to fix it that I missed inside these plug-ins?

Thank you very much once again!

 

Hi!

1. It is not possible, sorry. I have no control over the native camera app, even the screen with the retry and OK buttons is shown by the camera app. I regain control only after the camera is closed entirely. You'll have to call TakePicture continuously inside TakePicture's callback until the path is null (camera is closed with back button).

2. If you are loading the image via LoadImageAtPath, that is not the expected behaviour. I think it is the first time I'm hearing about this issue on Android, though. Is this behaviour persistent across all your test devices?

 

Hi yasirkula!

Thank you for your quick reply.

1. Oh that's a real bummer. I have to think something out, it wont be user friendly if user have to tap accept for every photo (and user will have to make around 30 photos in my app). Thats a real bummer...

2. Update for this problem. I tried on another device and it works fine as it should. So, on Xiaomi Mi 9T works fine, on Samsung S8 Plus is were the problem happens. Just so you know, the problem isn't on quad in front of the camera (talking about your example script), it happens when you save it to gallery.

 

For 1), you'll have to use a plugin that displays camera feed directly inside Unity and also supports capturing a photo with the camera. For example, this plugin might work for you but I haven't tried it myself, so no guarantees.

2) There are two SaveImageToGallery overloads: one takes "string path" parameter and the other takes "Texture2D texture" parameter. Can you try using the one you are not currently using and see if it changes anything? And for reference, which Android OS is your S8+ running on?

 

1. That's exactly what I was thinking, NatCam seems good enough for my purpose and a time cutter, I will give it a try.
2. I tested it out, with "Texture2D texture" parameter it works as it should on S8+. On both devices is Android 9.

Thank you for your effort!
