Ionic-native: File: checkFile(path, file) - FILE_NOT_FOUND

[pacMakaveli]

I'm submitting a ...
[x] bug report

Current behavior:

As per the File.checkFile documentation, when using this function, the directory argument can be a string.

MyClass

  checkFileExistence(fileName: string) {
    return this.fileService.checkFile(this.fileService.photosDir, fileName).then(() => {
      console.log('File exists');
      return this.fileService.getFile(this.fileService.photosDir, fileName);
    }, (error) => {
      console.log('File does not exist');
      console.error(error);
      return this.fileService.copyFile(this.fileService.tempDir, fileName, 'photos');
    })
  }

FileService

  public checkFile(directory: string, file: string): Promise<boolean> {
    return this.file.checkFile(directory, file)
  }

And this is my output when first executing the Function which creates the File. Which is correct because the File doesn't exist, yet.

[Log] File does not exist (ion-dev.js, line 156)
[Error] FileError {code: 1, message: "NOT_FOUND_ERR"}

    n (polyfills.js:2:28181)

However, when running it again, I get this:

Which is not correct because the File was previously created by the same function.

Expected behavior:

If I resolve the Directory in the checkFile function, like this:

Note: MyClass hasn't changed so I'm not going to put it again.

FileService

  public checkFile(directory: string, file: string): Promise<boolean> {
    return this.resolveDirectory(directory).then((resolvedDirectory: DirectoryEntry) => {
      return this.file.checkFile(resolvedDirectory.nativeURL, file)
    })
  }

This is my output.

...
[Log] File exists (ion-dev.js, line 156)
[Log] DirectoryEntry {isFile: false, isDirectory: true, name: "photos", fullPath: "/smartedi3/photos/", filesystem: FileSystem, …} (ion-dev.js, line 156)
[Log] cdv_photo_020.jpg (ion-dev.js, line 156)

I don't think this is necessarily a bug. However, the documentation should be changed to reflect this requirement as it's not that obvious that it needs to be a nativeURL string. Maybe instead of:

Param	Type	Details
path	string	Base FileSystem. Please refer to the iOS and Android filesystems above
file	string	Name of file to check

It should be:

Param	Type	Details
path	string	Directory nativeURL, obtained by resolveDirectoryURL
file	string	Name of file to check

I am facing same issue, receiving this error [{"code":1,"message":"NOT_FOUND_ERR"}] instead of a boolean false when file doesnt exists. I tried resolvedDirectoryUrl but that didnt work for me either. Know any other alternatives?

[pacMakaveli]

@pooja-gaikwad15 Worked for me. Add some relevant code and I'll have a look.

[pooja-gaikwad15]

var fileName = "data.json"; this.file.checkFile(this.file.applicationStorageDirectory, fileName) .then((result) => { console.log('file exists :' + result); },(error){ console.log('error : ' + JSON.stringify(error)});

Even tried checkFile function posted by you.. I am testing in android device.. [Iball-3G 1026-Q18 Android 4.4.2 API19]

[thecog19]

I also have this issue. Also testing on android.

EDIT: I will add more updates as i test different workarounds.

I'm having the same issue here. Constantly getting {"code":1,"message":"NOT_FOUND_ERR"} on both Android and iOS devices

Error when selected photo from Android gallery.

My solution:
// destinationType: this.camera.DestinationType.FILE_URI

Temporary image name generated by gallery (error):
IMG-20180105-WA0000.jpg?1515167526856

Correct name for new image (success):
IMG-20180105-WA0000.jpg

copyFile(imageData){
    let path = this.filePathUrl(imageData)
    let fileName = this.filePathName(imageData)
    let newPath = this.storageDirectory+'galeria/'
    let newFileName = fileName

    console.log('***********************************************')
    console.log('imageData')
    console.log(imageData)

    console.log('path')
    console.log(path)

    console.log('fileName')
    console.log(fileName)

    console.log('newPath')
    console.log(newPath)

    console.log('newFileName')
    console.log(newFileName)

    console.log('***********************************************')
    console.log('\n\n')

    this.file.copyFile(path, fileName, newPath, newFileName).then(data => {
      var itemSrc = data.nativeURL.replace(/^file:\/\//, '');
      this.imageFileName = itemSrc;
    }, err => {
      console.log(JSON.stringify(err))
    })
  }

filePathName(imageData){
    if(this.platform.is('android') && this.sourceType == 'galeria') {
      var nome = imageData.substr(imageData.lastIndexOf('/') + 1);
      nome = nome.split('?')
      return nome[0]
    }    
    return imageData.substr(imageData.lastIndexOf('/') + 1);
}
filePathUrl(imageData){
    return imageData.replace(this.filePathName(imageData), '');
}

I hope it works for you.

@pooja-gaikwad15, checkFile and checkDirectory never return false! The API is confusing. They return (a Promise returning) true if the thing exists, and an error (rejected Promise) otherwise.

[cyptus]

got this not found error because the passed file directory was not ending with /

[juusechec]

Adding '/' works for me!

Hi guys,
After so much trying, I found this solution to store images

let UUID = 'empleado-' + (new Date().getTime()).toString(16);

` // imagen = data:image/jpeg;base64,/9j/4........
let realData = imagen.split(",")[1];
let blob = this.b64toBlob(realData, 'image/jpeg');

this.file.checkDir(this.file.externalApplicationStorageDirectory, 'DirectorioFotos')
    .then(_ => {
      this.file.writeFile(this.file.externalApplicationStorageDirectory + 'DirectorioFotos/', UUID + '.jpg', blob).then(response => {
        // ACTION
      }).catch(err => {
        // ACTION
      })
    })
    .catch(err => {
      this.file.createDir(this.file.externalApplicationStorageDirectory, 'DirectorioFotos', false).then(result => {
        this.file.writeFile(this.file.externalApplicationStorageDirectory + 'DirectorioFotos/', UUID + '.jpg', blob).then(response => {
          // ACTION
        }).catch(err => {
          // ACTION
        })
      })
    });`

`b64toBlob(b64Data, contentType) {
contentType = contentType || '';
var sliceSize = 512;
var byteCharacters = atob(b64Data);
var byteArrays = [];

for (var offset = 0; offset < byteCharacters.length; offset += sliceSize) {
  var slice = byteCharacters.slice(offset, offset + sliceSize);

  var byteNumbers = new Array(slice.length);
  for (var i = 0; i < slice.length; i++) {
    byteNumbers[i] = slice.charCodeAt(i);
  }

  var byteArray = new Uint8Array(byteNumbers);

  byteArrays.push(byteArray);
}

var blob = new Blob(byteArrays, {type: contentType});
return blob;

}`

I hope someone is helpful
