HI, I am working on react-native new version, I have implement the html converter to pdf and got the base64 data. I have tried to download file in my Download folder. I am try download using this library but get the Permission denied error. I am add a android permissions, WRITE_EXTERNAL_STORAGE and <action android:name="android.intent.action.DOWNLOAD_COMPLETE"/>

But got the this error:

Error: Permission denied
    at Object.fn [as writeFile] (index.bundle?platfor…&minify=false:10730)
    at Object.writeFile (index.bundle?platfor…minify=false:334448)

Code:

createAndSavePDF = async() => {
        let options = {
            html: '<h1>This is a test PDF</h1>',
            fileName: 'test',
            directory: 'Download',
            base64: true
        };
        let file = await RNHTMLtoPDF.convert(options)

        // RNFetchBlob.fs.dirs.DownloadDir it's getting the download folder from internal storage
        let filePath = RNFetchBlob.fs.dirs.DownloadDir + '/testPDF.pdf';
        
        RNFetchBlob.fs.writeFile(filePath, file.base64, 'base64')
            .then(response => {
                console.log('Success Log: ', response);
            })
            .catch(errors => {
                console.log(" Error Log: ", errors);
            })
    }

I am working on debug mode on system.

Got the same problem in Android 10 when trying to copy a file with cp to Downloads directory.

    <application
        ...
        android:requestLegacyExternalStorage="true"
       ...
</application>

in AndroidManifesl.xml seems to help. Don't know if it is the issue with the library.

android:requestLegacyExternalStorage="true" its not found on targetSDKversion:28

On Android 10, you should to ask permissions through PermissionsAndroid

Try something like:

createAndSavePDF = async() => {
try {
    const granted = await PermissionsAndroid.request(
      PermissionsAndroid.PERMISSIONS.WRITE_EXTERNAL_STORAGE,
      {
        title: 'Cool Photo App Camera Permission',
        message:
          'Cool Photo App needs access to your camera ' +
          'so you can take awesome pictures.',
        buttonNeutral: 'Ask Me Later',
        buttonNegative: 'Cancel',
        buttonPositive: 'OK',
      },
    );
    if (granted === PermissionsAndroid.RESULTS.GRANTED) {
      console.log('You can use the camera');
 let options = {
            html: '<h1>This is a test PDF</h1>',
            fileName: 'test',
            directory: 'Download',
            base64: true
        };
        let file = await RNHTMLtoPDF.convert(options)

        // RNFetchBlob.fs.dirs.DownloadDir it's getting the download folder from internal storage
        let filePath = RNFetchBlob.fs.dirs.DownloadDir + '/testPDF.pdf';
        
        RNFetchBlob.fs.writeFile(filePath, file.base64, 'base64')
            .then(response => {
                console.log('Success Log: ', response);
            })
            .catch(errors => {
                console.log(" Error Log: ", errors);
            })
    } else {
      console.log('Camera permission denied');
    }
  } catch (err) {
    console.warn(err);
  }
       
    }

I'm also getting the same problem. @Peretz30 I asked for permission as well on the Android side through PermissionAndroid. After allowing permission, it is saying permission denied as an error. Anyone can help?

[Haseeba393]

@Pyroboomka I tried your listed method and now it is working perfect

This one works for me

i already have android:requestLegacyExternalStorage="true" in AndroidManifesl.xml. i always have permission denied no matter what i do.

try {
        const granted = await PermissionsAndroid.request(
          PermissionsAndroid.PERMISSIONS.WRITE_EXTERNAL_STORAGE,
          {
            title: 'Storage Permission Required',
            message: 'App needs access to your storage to download Photos',
          },
        );
        if (granted === PermissionsAndroid.RESULTS.GRANTED) {
          // Once user grant the permission start downloading
          console.log('Storage Permission Granted.');
          downloadImage();
        } else {
          // If permission denied then show alert
          alert('Storage Permission Not Granted');
        }
      } catch (err) {
        // To handle permission related exception
        console.warn(err);
      }

any fix in 2023 ? thanks
