Example

Checkout this example of a basic gallery app with infinite scroll:
https://github.com/bamlab/rn-camera-roll/tree/master/example

Setup

First, install the package:

npm install rn-camera-roll

Then, follow those instructions:

iOS

The Camera Roll iOS API is part of react-native. You have to import node_modules/react-native/Libraries/CameraRoll/RCTCameraRoll.xcodeproj by following the libraries linking instructions.

Android

Update your gradle files

For react-native >= v0.15, this command will do it automatically:

react-native link rn-camera-roll

For react-native = v0.14 You will have to update them manually:

In android/settings.gradle, add:

include ':rn-camera-roll'
project(':rn-camera-roll').projectDir = new File(settingsDir, '../node_modules/rn-camera-roll/android')

In android/app/build.gradle add:

dependencies {
  ...
  compile project(':rn-camera-roll')
}

Register the package into your MainActivity

package com.example;

import android.app.Activity;
import android.os.Bundle;
import android.view.KeyEvent;

import com.facebook.react.LifecycleState;
import com.facebook.react.ReactInstanceManager;
import com.facebook.react.ReactRootView;
import com.facebook.react.modules.core.DefaultHardwareBackBtnHandler;
import com.facebook.react.shell.MainReactPackage;
import com.facebook.soloader.SoLoader;

// IMPORT HERE
import fr.bamlab.rncameraroll.CameraRollPackage;
// ---

public class MainActivity extends Activity implements DefaultHardwareBackBtnHandler {

    private ReactInstanceManager mReactInstanceManager;
    private ReactRootView mReactRootView;

    @Override
    protected void onCreate(Bundle savedInstanceState) {
        super.onCreate(savedInstanceState);
        mReactRootView = new ReactRootView(this);

        mReactInstanceManager = ReactInstanceManager.builder()
                .setApplication(getApplication())
                .setBundleAssetName("index.android.bundle")
                .setJSMainModuleName("index.android")
                .addPackage(new MainReactPackage())

                // REGISTER PACKAGE HERE
                .addPackage(new CameraRollPackage())
                // ---
                .setUseDeveloperSupport(BuildConfig.DEBUG)
                .setInitialLifecycleState(LifecycleState.RESUMED)
                .build();

        mReactRootView.startReactApplication(mReactInstanceManager, "example", null);

        setContentView(mReactRootView);
    }

    ...

Usage

You can use the getPhotos API as you would with the iOS API with the after and the first params. You can use both the promise syntax or the callback syntax.

import CameraRoll from 'rn-camera-roll';

onPhotosFetchedSuccess(data) {
  const photos = data.edges.map((asset) => {
    return asset.node.image;
  });
  console.log(photos);
  /**
  On Android, this should log something like:
  [
    {
      "uri": "file:/storage/emulated/0/DCIM/Camera/IMG_20160120_172426830.jpg",
      "width":3006,
      "height":5344,
      "orientation": 90
    },
    {
      "uri": "file:/storage/emulated/0/DCIM/Camera/IMG_20160116_153526816_TOP.jpg",
      "width": 5344,
      "height": 3006,
      "orientation": 0
    }
    ...
  ]
  **/
}

onPhotosFetchError(err) {
  // Handle error here
}

fetchPhotos(count = 10, after) {
  CameraRoll.getPhotos({
    // take the first n photos after given photo uri
    first: count,
    // after
    after: "file:/storage/emulated/0/DCIM/Camera/IMG_20151126_115520477.jpg",
  }, this.onPhotosFetchedSuccess.bind(this), this.onPhotosFetchError.bind(this));
}
