## Description
Using Cordova 10.0.0 and cordova-plugin-camera 5.0.0, when I call
camera.getPicture() and use FileReader.readAsArrayBuffer() on the resulting
FILE_URI, the camera app seems to run OK but the result is {}, i.e. an empty
object. This is when the saveToPhotoAlbum option is false. (When that option
is true, getPicture() results in "Error capturing image".)
## Information
I'm using a Pixel 2 XL emulator from the latest Android Studio for Linux,
targeting Android 7.1.1 (API 25). (Other than that, I don't use Studio; I just
use the cordova command line.) I haven't tried this on a physical phone, nor
have I tried it on iOS.
### Command or Code
Here's the relevant code:
` let options= {quality: 100,
destinationType: Camera.DestinationType.FILE_URI,
sourceType: Camera.PictureSourceType.CAMERA,
encodingType: Camera.EncodingType.PNG,
targetWidth: 600,
targetHeight: 600,
mediaType: Camera.MediaType.PICTURE,
correctOrientation: true,
saveToPhotoAlbum: false
} ;
let photo_url= await new Promise((resolve, reject) =>
navigator.camera.getPicture(function(result) {
alert('in getPicture success,
result=['+JSON.stringify(result)+']') ;
resolve(result) ;
}, function(err) {
alert('in getPicture error, err=['+JSON.stringify(err)+']') ;
reject(err) ;
}, options)) ;
let img_file_entry= await url_to_entry(photo_url) ;
let img_data= await read_file_binary(img_file_entry) ;
`
... and here are those two routines from a short file IO library:
`async function read_file_binary(file_entry) {
// file_entry.fullPath looks correct at this point
return new Promise((resolve, reject) => {
file_entry.file(file => {
let reader = new FileReader() ;
reader.onloadend= function(e) {
resolve(this.result) ; // this.result is now an empty
object {}
} ;
reader.readAsArrayBuffer(file) ;
}) ;
}) ;
}
function url_to_entry(url) {
return new Promise((resolve, reject) => resolveLocalFileSystemURL(url,
resolve, reject)) ;
}
`
