cordova-plugin-camera

This plugin defines a global navigator.camera object, which provides an API for taking pictures and for choosing images from the system's image library.

Although the object is attached to the global scoped navigator, it is not available until after the deviceready event.

document.addEventListener("deviceready", onDeviceReady, false);
function onDeviceReady() {
    console.log(navigator.camera);
}

Installation

This requires cordova 5.0+

cordova plugin add cordova-plugin-camera

Older versions of cordova can still install via the deprecated id

cordova plugin add org.apache.cordova.camera

It is also possible to install via repo url directly ( unstable )

cordova plugin add https://github.com/apache/cordova-plugin-camera.git

iOS Quirks

Since iOS 10 it's mandatory to provide an usage description in the info.plist if trying to access privacy-sensitive data. When the system prompts the user to allow access, this usage description string will displayed as part of the permission dialog box, but if you didn't provide the usage description, the app will crash before showing the dialog. Also, Apple will reject apps that access private data but don't provide an usage description.

This plugins requires the following usage descriptions:

• NSCameraUsageDescription specifies the reason for your app to access the device's camera.
• NSPhotoLibraryUsageDescription specifies the reason for your app to access the user's photo library.
• NSLocationWhenInUseUsageDescription specifies the reason for your app to access the user's location information while your app is in use. (Set it if you have CameraUsesGeolocation preference set to true)
• NSPhotoLibraryAddUsageDescription specifies the reason for your app to get write-only access to the user's photo library

To add these entries into the info.plist, you can use the edit-config tag in the config.xml like this:

<edit-config target="NSCameraUsageDescription" file="*-Info.plist" mode="merge">
    <string>need camera access to take pictures</string>
</edit-config>

<edit-config target="NSPhotoLibraryUsageDescription" file="*-Info.plist" mode="merge">
    <string>need photo library access to get pictures from there</string>
</edit-config>

<edit-config target="NSLocationWhenInUseUsageDescription" file="*-Info.plist" mode="merge">
    <string>need location access to find things nearby</string>
</edit-config>

<edit-config target="NSPhotoLibraryAddUsageDescription" file="*-Info.plist" mode="merge">
    <string>need photo library access to save pictures there</string>
</edit-config>

camera

camera.getPicture(successCallback, errorCallback, options)

Takes a photo using the camera, or retrieves a photo from the device's image gallery. The image is passed to the success callback as a Base64-encoded String, or as the URI for the image file.

The camera.getPicture function opens the device's default camera application that allows users to snap pictures by default - this behavior occurs, when Camera.sourceType equals Camera.PictureSourceType.CAMERA. Once the user snaps the photo, the camera application closes and the application is restored.

If Camera.sourceType is Camera.PictureSourceType.PHOTOLIBRARY or Camera.PictureSourceType.SAVEDPHOTOALBUM, then a dialog displays that allows users to select an existing image.

The return value is sent to the cameraSuccess callback function, in one of the following formats, depending on the specified cameraOptions:

• A String containing the Base64-encoded photo image.
• A String representing the image file location on local storage (default).

You can do whatever you want with the encoded image or URI, for example:

• Render the image in an <img> tag, as in the example below
• Save the data locally (LocalStorage, Lawnchair, etc.)
• Post the data to a remote server

NOTE: Photo resolution on newer devices is quite good. Photos selected from the device's gallery are not downscaled to a lower quality, even if a quality parameter is specified. To avoid common memory problems, set Camera.destinationType to FILE_URI rather than DATA_URL.

camera.getPicture Errata

Example

Take a photo and retrieve the image's file location:

navigator.camera.getPicture(onSuccess, onFail, { quality: 50,
    destinationType: Camera.DestinationType.FILE_URI });

function onSuccess(imageURI) {
    var image = document.getElementById('myImage');
    image.src = imageURI;
}

function onFail(message) {
    alert('Failed because: ' + message);
}

Take a photo and retrieve it as a Base64-encoded image:

/**
 * Warning: Using DATA_URL is not recommended! The DATA_URL destination
 * type is very memory intensive, even with a low quality setting. Using it
 * can result in out of memory errors and application crashes. Use FILE_URI
 * or NATIVE_URI instead.
 */
navigator.camera.getPicture(onSuccess, onFail, { quality: 25,
    destinationType: Camera.DestinationType.DATA_URL
});

function onSuccess(imageData) {
    var image = document.getElementById('myImage');
    image.src = "data:image/jpeg;base64," + imageData;
}

function onFail(message) {
    alert('Failed because: ' + message);
}

Preferences (iOS)

• CameraUsesGeolocation (boolean, defaults to false). For capturing JPEGs, set to true to get geolocation data in the EXIF header. This will trigger a request for geolocation permissions if set to true.

   <preference name="CameraUsesGeolocation" value="false" />
  

Amazon Fire OS Quirks

Amazon Fire OS uses intents to launch the camera activity on the device to capture images, and on phones with low memory, the Cordova activity may be killed. In this scenario, the image may not appear when the Cordova activity is restored.

Android Quirks

Android uses intents to launch the camera activity on the device to capture images, and on phones with low memory, the Cordova activity may be killed. In this scenario, the result from the plugin call will be delivered via the resume event. See the Android Lifecycle guide for more information. The pendingResult.result value will contain the value that would be passed to the callbacks (either the URI/URL or an error message). Check the pendingResult.pluginStatus to determine whether or not the call was successful.

Browser Quirks

Can only return photos as Base64-encoded image.

Firefox OS Quirks

Camera plugin is currently implemented using Web Activities.

iOS Quirks

Including a JavaScript alert() in either of the callback functions can cause problems. Wrap the alert within a setTimeout() to allow the iOS image picker or popover to fully close before the alert displays:

setTimeout(function() {
    // do your thing here!
}, 0);

Windows Phone 7 Quirks

Invoking the native camera application while the device is connected via Zune does not work, and triggers an error callback.

Windows quirks

On Windows Phone 8.1 using SAVEDPHOTOALBUM or PHOTOLIBRARY as a source type causes application to suspend until file picker returns the selected image and then restore with start page as defined in app's config.xml. In case when camera.getPicture was called from different page, this will lead to reloading start page from scratch and success and error callbacks will never be called.

To avoid this we suggest using SPA pattern or call camera.getPicture only from your app's start page.

More information about Windows Phone 8.1 picker APIs is here: How to continue your Windows Phone app after calling a file picker

Tizen Quirks

Tizen only supports a destinationType of Camera.DestinationType.FILE_URI and a sourceType of Camera.PictureSourceType.PHOTOLIBRARY.

CameraOptions Errata

Amazon Fire OS Quirks

• Any cameraDirection value results in a back-facing photo.

• Ignores the allowEdit parameter.

• Camera.PictureSourceType.PHOTOLIBRARY and Camera.PictureSourceType.SAVEDPHOTOALBUM both display the same photo album.

Android Quirks

• Any cameraDirection value results in a back-facing photo.

• allowEdit is unpredictable on Android and it should not be used! The Android implementation of this plugin tries to find and use an application on the user's device to do image cropping. The plugin has no control over what application the user selects to perform the image cropping and it is very possible that the user could choose an incompatible option and cause the plugin to fail. This sometimes works because most devices come with an application that handles cropping in a way that is compatible with this plugin (Google Plus Photos), but it is unwise to rely on that being the case. If image editing is essential to your application, consider seeking a third party library or plugin that provides its own image editing utility for a more robust solution.

• Camera.PictureSourceType.PHOTOLIBRARY and Camera.PictureSourceType.SAVEDPHOTOALBUM both display the same photo album.

• Ignores the encodingType parameter if the image is unedited (i.e. quality is 100, correctOrientation is false, and no targetHeight or targetWidth are specified). The CAMERA source will always return the JPEG file given by the native camera and the PHOTOLIBRARY and SAVEDPHOTOALBUM sources will return the selected file in its existing encoding.

BlackBerry 10 Quirks

• Ignores the quality parameter.

• Ignores the allowEdit parameter.

• Camera.MediaType is not supported.

• Ignores the correctOrientation parameter.

• Ignores the cameraDirection parameter.

Firefox OS Quirks

• Ignores the quality parameter.

• Camera.DestinationType is ignored and equals 1 (image file URI)

• Ignores the allowEdit parameter.

• Ignores the PictureSourceType parameter (user chooses it in a dialog window)

• Ignores the encodingType

• Ignores the targetWidth and targetHeight

• Camera.MediaType is not supported.

• Ignores the correctOrientation parameter.

• Ignores the cameraDirection parameter.

iOS Quirks

• When using destinationType.FILE_URI, photos are saved in the application's temporary directory. The contents of the application's temporary directory is deleted when the application ends.

• When using destinationType.NATIVE_URI and sourceType.CAMERA, photos are saved in the saved photo album regardless on the value of saveToPhotoAlbum parameter.

• When using destinationType.NATIVE_URI and sourceType.PHOTOLIBRARY or sourceType.SAVEDPHOTOALBUM, all editing options are ignored and link is returned to original picture.

Tizen Quirks

• options not supported

• always returns a FILE URI

Windows Phone 7 and 8 Quirks

• Ignores the allowEdit parameter.

• Ignores the correctOrientation parameter.

• Ignores the cameraDirection parameter.

• Ignores the saveToPhotoAlbum parameter. IMPORTANT: All images taken with the WP8/8 Cordova camera API are always copied to the phone's camera roll. Depending on the user's settings, this could also mean the image is auto-uploaded to their OneDrive. This could potentially mean the image is available to a wider audience than your app intended. If this is a blocker for your application, you will need to implement the CameraCaptureTask as documented on MSDN. You may also comment or up-vote the related issue in the issue tracker.

• Ignores the mediaType property of cameraOptions as the Windows Phone SDK does not provide a way to choose videos from PHOTOLIBRARY.

Sample: Take Pictures, Select Pictures from the Picture Library, and Get Thumbnails

The Camera plugin allows you to do things like open the device's Camera app and take a picture, or open the file picker and select one. The code snippets in this section demonstrate different tasks including:

• Open the Camera app and take a Picture
• Take a picture and return thumbnails (resized picture)
• Take a picture and generate a FileEntry object
• Select a file from the picture library
• Select a JPEG image and return thumbnails (resized image)
• Select an image and generate a FileEntry object

Take a Picture

Before you can take a picture, you need to set some Camera plugin options to pass into the Camera plugin's getPicture function. Here is a common set of recommendations. In this example, you create the object that you will use for the Camera options, and set the sourceType dynamically to support both the Camera app and the file picker.

function setOptions(srcType) {
    var options = {
        // Some common settings are 20, 50, and 100
        quality: 50,
        destinationType: Camera.DestinationType.FILE_URI,
        // In this app, dynamically set the picture source, Camera or photo gallery
        sourceType: srcType,
        encodingType: Camera.EncodingType.JPEG,
        mediaType: Camera.MediaType.PICTURE,
        allowEdit: true,
        correctOrientation: true  //Corrects Android orientation quirks
    }
    return options;
}

Typically, you want to use a FILE_URI instead of a DATA_URL to avoid most memory issues. JPEG is the recommended encoding type for Android.

You take a picture by passing in the options object to getPicture, which takes a CameraOptions object as the third argument. When you call setOptions, pass Camera.PictureSourceType.CAMERA as the picture source.

function openCamera(selection) {

    var srcType = Camera.PictureSourceType.CAMERA;
    var options = setOptions(srcType);
    var func = createNewFileEntry;

    navigator.camera.getPicture(function cameraSuccess(imageUri) {

        displayImage(imageUri);
        // You may choose to copy the picture, save it somewhere, or upload.
        func(imageUri);

    }, function cameraError(error) {
        console.debug("Unable to obtain picture: " + error, "app");

    }, options);
}

Once you take the picture, you can display it or do something else. In this example, call the app's displayImage function from the preceding code.

function displayImage(imgUri) {

    var elem = document.getElementById('imageFile');
    elem.src = imgUri;
}

To display the image on some platforms, you might need to include the main part of the URI in the Content-Security-Policy <meta> element in index.html. For example, on Windows 10, you can include ms-appdata: in your <meta> element. Here is an example.

<meta http-equiv="Content-Security-Policy" content="default-src 'self' data: gap: ms-appdata: https://ssl.gstatic.com 'unsafe-eval'; style-src 'self' 'unsafe-inline'; media-src *">

Take a Picture and Return Thumbnails (Resize the Picture)

To get smaller images, you can return a resized image by passing both targetHeight and targetWidth values with your CameraOptions object. In this example, you resize the returned image to fit in a 100px by 100px box (the aspect ratio is maintained, so 100px is either the height or width, whichever is greater in the source).

function openCamera(selection) {

    var srcType = Camera.PictureSourceType.CAMERA;
    var options = setOptions(srcType);
    var func = createNewFileEntry;

    if (selection == "camera-thmb") {
        options.targetHeight = 100;
        options.targetWidth = 100;
    }

    navigator.camera.getPicture(function cameraSuccess(imageUri) {

        // Do something

    }, function cameraError(error) {
        console.debug("Unable to obtain picture: " + error, "app");

    }, options);
}

Select a File from the Picture Library

When selecting a file using the file picker, you also need to set the CameraOptions object. In this example, set the sourceType to Camera.PictureSourceType.SAVEDPHOTOALBUM. To open the file picker, call getPicture just as you did in the previous example, passing in the success and error callbacks along with CameraOptions object.

function openFilePicker(selection) {

    var srcType = Camera.PictureSourceType.SAVEDPHOTOALBUM;
    var options = setOptions(srcType);
    var func = createNewFileEntry;

    navigator.camera.getPicture(function cameraSuccess(imageUri) {

        // Do something

    }, function cameraError(error) {
        console.debug("Unable to obtain picture: " + error, "app");

    }, options);
}

Select an Image and Return Thumbnails (resized images)

Resizing a file selected with the file picker works just like resizing using the Camera app; set the targetHeight and targetWidth options.

function openFilePicker(selection) {

    var srcType = Camera.PictureSourceType.SAVEDPHOTOALBUM;
    var options = setOptions(srcType);
    var func = createNewFileEntry;

    if (selection == "picker-thmb") {
        // To downscale a selected image,
        // Camera.EncodingType (e.g., JPEG) must match the selected image type.
        options.targetHeight = 100;
        options.targetWidth = 100;
    }

    navigator.camera.getPicture(function cameraSuccess(imageUri) {

        // Do something with image

    }, function cameraError(error) {
        console.debug("Unable to obtain picture: " + error, "app");

    }, options);
}

Take a picture and get a FileEntry Object

If you want to do something like copy the image to another location, or upload it somewhere using the FileTransfer plugin, you need to get a FileEntry object for the returned picture. To do that, call window.resolveLocalFileSystemURL on the file URI returned by the Camera app. If you need to use a FileEntry object, set the destinationType to Camera.DestinationType.FILE_URI in your CameraOptions object (this is also the default value).

Note You need the File plugin to call window.resolveLocalFileSystemURL.

Here is the call to window.resolveLocalFileSystemURL. The image URI is passed to this function from the success callback of getPicture. The success handler of resolveLocalFileSystemURL receives the FileEntry object.

function getFileEntry(imgUri) {
    window.resolveLocalFileSystemURL(imgUri, function success(fileEntry) {

        // Do something with the FileEntry object, like write to it, upload it, etc.
        // writeFile(fileEntry, imgUri);
        console.log("got file: " + fileEntry.fullPath);
        // displayFileData(fileEntry.nativeURL, "Native URL");

    }, function () {
      // If don't get the FileEntry (which may happen when testing
      // on some emulators), copy to a new FileEntry.
        createNewFileEntry(imgUri);
    });
}

In the example shown in the preceding code, you call the app's createNewFileEntry function if you don't get a valid FileEntry object. The image URI returned from the Camera app should result in a valid FileEntry, but platform behavior on some emulators may be different for files returned from the file picker.

Note To see an example of writing to a FileEntry, see the File plugin README.

The code shown here creates a file in your app's cache (in sandboxed storage) named tempFile.jpeg. With the new FileEntry object, you can copy the image to the file or do something else like upload it.

function createNewFileEntry(imgUri) {
    window.resolveLocalFileSystemURL(cordova.file.cacheDirectory, function success(dirEntry) {

        // JPEG file
        dirEntry.getFile("tempFile.jpeg", { create: true, exclusive: false }, function (fileEntry) {

            // Do something with it, like write to it, upload it, etc.
            // writeFile(fileEntry, imgUri);
            console.log("got file: " + fileEntry.fullPath);
            // displayFileData(fileEntry.fullPath, "File copied to");

        }, onErrorCreateFile);

    }, onErrorResolveUrl);
}
