Optimize Toolset

I’ve always been into building performant and accessible sites, but lately I’ve been taking it extremely seriously. So much so that I’ve been building a tool to help me optimize and monitor the sites that I build to make sure that I’m making an attempt to offer the best experience to those who visit them. If you’re into performant, accessible and SEO friendly sites, you might like it too! You can check it out at Optimize Toolset.

About

Hi, 👋, I’m Ryan Hefner  and I built this site for me, and you! The goal of this site was to provide an easy way for me to check the stats on my npm packages, both for prioritizing issues and updates, and to give me a little kick in the pants to keep up on stuff.

As I was building it, I realized that I was actually using the tool to build the tool, and figured I might as well put this out there and hopefully others will find it to be a fast and useful way to search and browse npm packages as I have.

If you’re interested in other things I’m working on, follow me on Twitter or check out the open source projects I’ve been publishing on GitHub.

I am also working on a Twitter bot for this site to tweet the most popular, newest, random packages from npm. Please follow that account now and it will start sending out packages soon–ish.

Open Software & Tools

This site wouldn’t be possible without the immense generosity and tireless efforts from the people who make contributions to the world and share their work via open source initiatives. Thank you 🙏

Readme

react-native-delete-media

Supports Android MIT License

react-native-delete-media 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

$ yarn add react-native-delete-media

or

$ npm install react-native-delete-media

Library configuration

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

    include 'react-native-delete-media'
    project(':react-native-delete-media').projectDir = new File(rootProject.projectDir, '../node_modules/react-native-delete-media/android')
  2. Insert the following lines inside the dependencies block in android/app/build.gradle:

      implementation project(':react-native-delete-media')
  3. Add the following lines to your imports in android/app/src/main/java/com/[projectname]/MainActivity.java:

        import com.rtndeletemedia.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.rtndeletemedia.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' 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 "react-native-delete-media";

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 DeleteImage() {
  if (Platform.OS !== "android") {
    return;
  }

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

  const uri = "file:///storage/emulated/0/DCIM/Camera/photo.jpg";

  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;
      }
    });
}
