pod 'react-native-document-edoc2', :path => '../node_modules/react-native-document-edoc2`

Android

// file: android/settings.gradle
...

include ':react-native-document-edoc2'
project(':react-native-document-edoc2').projectDir = new File(rootProject.projectDir, '../node_modules/react-native-document-edoc2/android')

// file: android/app/build.gradle
...

dependencies {
    ...
    compile project(':react-native-document-edoc2')
}

// file: MainApplication.java
...

import com.reactnativedocumentpicker.ReactNativeDocumentPicker;; // Import package

public class MainApplication extends Application implements ReactApplication {

   /**
   * A list of packages used by the app. If the app uses additional views
   * or modules besides the default ones, add more packages here.
   */
    @Override
    protected List<ReactPackage> getPackages() {
      return Arrays.<ReactPackage>asList(
          new MainReactPackage(),
            new ReactNativeDocumentPicker() // Add package
      );
    }
...
}

Example

import { DocumentPicker, DocumentPickerUtil } from 'react-native-document-edoc2';

// iPhone/Android
DocumentPicker.show({
      filetype: [DocumentPickerUtil.images()],
    },(error,res) => {
      // Android
      console.log(
         res.uri,
         res.type, // mime type
         res.fileName,
         res.fileSize
      );
    });

// iPad
const {pageX, pageY} = event.nativeEvent;

DocumentPicker.show({
  top: pageY,
  left: pageX,
  filetype: ['public.image'],
}, (error, url) => {
  alert(url);
});

How to send it back ?

I recommend using https://github.com/johanneslumpe/react-native-fs I had to modify Uploader.m so it would use NSFileCoordinator with NSFileCoordinatorReadingForUploading option.

I added a check for file length that would be thrown into RNFS catch block.

if ([fileData length] == 0) {
    NSError *errorUp = [NSError errorWithDomain:@"com.whatever.yourapp" code:77 userInfo:[NSDictionary dictionaryWithObject:@"empty" forKey:NSLocalizedDescriptionKey]];
    _params.errorCallback(errorUp);
    return;
}

let url = "file://whatever/com.bla.bla/file.ext"; //The url you received from the DocumentPicker

// I STRONGLY RECOMMEND ADDING A SMALL SETTIMEOUT before uploading the url you just got.
const split = url.split('/');
const name = split.pop();
const inbox = split.pop();
const realPath = `${RNFS.TemporaryDirectoryPath}${inbox}/${name}`;

const uploadBegin = (response) => {
  const jobId = response.jobId;
  console.log('UPLOAD HAS BEGUN! JobId: ' + jobId);
};

const uploadProgress = (response) => {
  const percentage = Math.floor((response.totalBytesSent/response.totalBytesExpectedToSend) * 100);
  console.log('UPLOAD IS ' + percentage + '% DONE!');
};

RNFS.uploadFiles({
   toUrl: uploadUrl,
   files: [{
      name,
      filename:name,
      filepath: realPath,
    }],
   method: 'POST',
   headers: {
      'Accept': 'application/json',
   },
   begin: uploadBegin,
   beginCallback: uploadBegin, // Don't ask me, only way I made it work as of 1.5.1
   progressCallback: uploadProgress,
   progress: uploadProgress
   })
   .then((response) => {
     console.log(response,"<<< Response");
     if (response.statusCode == 200) { //You might not be getting a statusCode at all. Check
        console.log('FILES UPLOADED!');
      } else {
        console.log('SERVER ERROR');
       }
     })
     .catch((err) => {
       if (err.description) {
         switch (err.description) {
           case "cancelled":
             console.log("Upload cancelled");
             break;
           case "empty"
             console.log("Empty file");
           default:
            //Unknown
         }
       } else {
        //Weird
       }
       console.log(err);
    });

File Type

All type of Files 'public.allFiles' or DocumentPickerUtil.allFiles() Only PDF 'public.pdf' or DocumentPickerUtil.pdf() Audio 'public.audio' or DocumentPickerUtil.audio() Plain Text 'public.plainText' or DocumentPickerUtil.plainText()

Reminder

You need to enable iCloud Documents to access iCloud

Halp wanted: Improvements

• Fix Xcode warning about constraints
• support options for the UIDocumentMenuViewController
• Handle Upload by itself ?
