> we are facing a similar issue where existing cordova implementation to
read a file from downloads folder is working but not in android 11. Have tried
all possible changes suggested to use fileentry object to get reference and
then copy to a location where application has access to but read itself is
failing. Cordova version used is 9.x and cordova-file-plugin has been used to
read file. Required feature is to allow user to select a file from device and
upload it. Upload to server is in base64 format. Kindly advise
>
> @alex-steinberg - can you please share your code snippet and clarify
whether you are using cordova 9 or cordova 10?
@alex-steinberg - We have set targetSdkVersion to 30 in config.xml file and
created build using platform 9.1.0.
Below code works fine in lower android version (till android 10). In android
11 while reading a **pdf file** from download loaction, we get error as **GET
file:///storage/emulated/0/Download/Test.pdf net::ERR_ACCESS_DENIED**
this.fileChooser.open()
.then(uri => {
let fileName = null;
let fileExtension = null;
let fileType = null;
let isvalid = true;
this.filePath.resolveNativePath(uri)
.then(filePath => {
return this.base64EncodeFile(filePath);
}).then((base64Data: any)=>{
console.log(base64Data);
})
.catch(err => console.log(err));
})
.catch(e => console.log(e));
}
base64EncodeFile(src){
return new Promise((resolve, reject) => {
let xhr = new XMLHttpRequest();
xhr.onload = function () {
let reader = new FileReader();
reader.onloadend = function () {
let result = {
base64: reader.result,
size: xhr.response.size,
type: xhr.response.type
}
resolve(result);
}
reader.readAsDataURL(xhr.response);
};
xhr.open('GET', src);
xhr.responseType = 'blob';
xhr.send();
});
}
We have also tried below code
To copy from download folder to internal storage. It gives
**{"code":1,"message":"NOT_FOUND_ERR"}** error
pathsrc : file:///storage/emulated/0/Download/Test.pdf
fileName : Test.pdf
this.file.copyFile(pathsrc, fileName, this.file.dataDirectory, fileName).
then((result) => { console.log('file copied :' + result);
}).catch(err => console.log("copied err "+
JSON.stringify(err)));;
Below code is using copyTo method, it gives error as **FileError {code: 1}**
window.resolveLocalFileSystemURL(pathsrc, function (fileSystem) {
fileSystem.getFile(fileName, {
create: false, // try true first to make sure that there are
no other problems around
exclusive: false
}, function (fileEntry) {
window.resolveLocalFileSystemURL(window.cordova.file.externalDataDirectory ,
function (newFileEntry) {
fileEntry.copyTo(newFileEntry, fileName, function (result) {
console.log("save successfully:", result);
}, function (err) {
console.log("err-fileEntry.copyTo: ",err);
});
}, function (err) {
console.log("err-window.resolveLocalFileSystemURL: ",err);
});
}, function (err) {
console.log("err-fileSystem.getFile: ",err);
});
}, function (err) {
console.log("err-resolveLocalFileSystemURL: ",err);
});
