Out of memory error when writing big files say 50Mb -100Mb on Android.

//const base64Data is read from "RNFS.readFile(item.uri, 'base64')" function...

const isPlatformAndroid = (Platform.OS === 'android');
 const folder = isPlatformAndroid ?"RNFS.ExternalStorageDirectoryPath/"+appName+"/Vids/" : "RNFS.DocumentDirectoryPath/"+appName+"/Vids/";
const fileName = new Date().getTime() + .mp4;
const file_path_ = isPlatformAndroid ? "file://+"folder"+"fileName" : "file://+"folder"+"fileName";

                                              // write the file with options 'base64'
                                                RNFS.writeFile(file_path_, base64Data, 'base64')
                                                    .then(() => {})
                                                    .catch(error =>  console.log(error.message));
