@kunalukey/react-native-mediastore

NOTE: This module extends the react-native-delete-media module to support deleting videos as well

react-native-mediastore is a react native module used to delete media on android using the new scoped storage. It only supports Android.

It uses the native MediaStore.createDeleteRequest function to launch the android activity responsible for asking the user permission to delete a media file.

Getting started

Installing

$ npm install @kunalukey/react-native-mediastore

Library configuration

1. Append the following lines to android/settings.gradle:

   include 'kunalukey_react-native-mediastore'
   project(':kunalukey_react-native-mediastore').projectDir = new File(rootProject.projectDir, '../node_modules/@kunalukey/react-native-mediastore/android')

2. Insert the following lines inside the dependencies block in android/app/build.gradle:

     implementation project(':kunalukey_react-native-mediastore')

3. Add the following lines to your imports in android/app/src/main/java/com/[projectname]/MainActivity.java:

       import com.kunalukey.mediastore.DeleteMediaModule;
       import android.os.Bundle;

4. Create the OnCreate method in MainActivity.java, if you already have an OnCreate function just add the init line:

   @Override
   public void onCreate(Bundle savedInstanceState) {
       super.onCreate(savedInstanceState);
       DeleteMediaModule.init(this);
   }

   Your MainActivity.java file should look like this:

   import com.facebook.react.ReactActivity;
   import com.facebook.react.ReactActivityDelegate;
   import com.facebook.react.defaults.DefaultNewArchitectureEntryPoint;
   import com.facebook.react.defaults.DefaultReactActivityDelegate;
   
   import com.rtndeletemedia.DeleteMediaModule;
   import android.os.Bundle;
   
   public class MainActivity extends ReactActivity {
   
   @Override
     public void onCreate(Bundle savedInstanceState) {
         super.onCreate(savedInstanceState);
         DeleteMediaModule.init(this);
     }
   ...
   ...
   }
   

5. Make sure to rebuild using yarn android.

Linking

This module was created using the new Turbo Native Modules. It needs to have the New Architecture enabled in the android/gradle.properties file.

If you're project is not using New Architecture, you'll need to link the library manually.

To do so:

1. Follow the steps in the Library configuration section.

2. In the android/app/src/main/java/com/[projectname]/MainApplication.java file, add:

   • import com.kunalukey.mediastore.DeleteMediaPackage; to the list of imports at the top of the file.

   • packages.add(new DeleteMediaPackage()); to the getPackages() method.

Note: If you the this error while trying to use the module [TypeError: Cannot read property 'deletePhotos' / 'deleteVideos' of null] you probably need to manually link it.

Permissions

You will need to add the WRITE_EXTERNAL_STORAGE permission to your android manifest

<manifest xmlns:android="http://schemas.android.com/apk/res/android">

    <uses-permission android:name="android.permission.WRITE_EXTERNAL_STORAGE"/>

    <application
      ...
    </application>
</manifest>

And make sure to request it before calling any functions from this module.

Usage

Here is a simple example of using the library.

import { PermissionsAndroid, Platform } from "react-native";
import { DeleteMedia, ErrorCodes } from "@kunalukey/react-native-mediastore";

async function hasAndroidPermission() {
  const permission = PermissionsAndroid.PERMISSIONS.WRITE_EXTERNAL_STORAGE;

  const hasPermission = await PermissionsAndroid.check(permission);
  if (hasPermission) {
    return true;
  }

  const status = await PermissionsAndroid.request(permission);
  return status === "granted";
}

async function performDelete() {
  if (Platform.OS !== "android") {
    return;
  }

  if (!(await hasAndroidPermission())) {
    return;
  }

  const photoURI = "file:///storage/emulated/0/DCIM/Camera/photo.jpg";
  const videoURI = "file:///storage/emulated/0/DCIM/Camera/video.mp4";

  // Delete photo
  DeleteMedia.deletePhotos([uri])
    .then(() => {
      console.log("Image deleted");
    })
    .catch((e) => {
      const message = e.message;
      const code: ErrorCodes = e.code;

      switch (code) {
        case "ERROR_USER_REJECTED":
          console.log("Image deletion denied by user");
          break;
        default:
          console.log(message);
          break;
      }
    });

  // Delete video  
  DeleteMedia.deleteVideos([uri])
    .then(() => {
      console.log("Video deleted");
    })
    .catch((e) => {
      const message = e.message;
      const code: ErrorCodes = e.code;

      switch (code) {
        case "ERROR_USER_REJECTED":
          console.log("Video deletion denied by user");
          break;
        default:
          console.log(message);
          break;
      }
    });
}
