App crashes while reading file on android, Error: java.lang.NumberFormatException

See original GitHub issue

Versions:

"react-native-fetch-blob": "0.10.8"
"react-native": "0.49.5"

I was reading a file using this code:

RNFetchBlob.fs
      .readFile(filePath, "ascii")
      .then(data => {
        this.showProgressModal = true;
        ...
      }).catch(e){}

On Android device I got this error and app crashes:

java.lang.NumberFormatException: For input string: "raw:/storage/emulated/0/Download/Bittrexv1.csv"
                                                                             at java.lang.Long.parseLong(Long.java:590)

                                                                             at java.util.concurrent.ThreadPoolExecutor.runWorker(ThreadPoolExecutor.java:1162)
                                                                             at java.util.concurrent.ThreadPoolExecutor$Worker.run(ThreadPoolExecutor.java:636)
                                                                             at java.lang.Thread.run(Thread.java:764)

PS. Its working fine on Android emulator and ios simulator. Haven’t tested on ios device yet. Please let me know if more information is needed to debug the issue, Thanks!

simple workaround just for now.

const filePath = item.uri.split('raw%3A')[1].replace(/\%2F/gm, '/');
RNFetchBlob.fs.readFile(filePath, 'utf8').then(...)
