Hey everyone,  
Currently I am using the ionic file plugin in capacitor. When I want to build this app I keep getting the following errors:

error: package android.support.v4.content does not exist  
public class FileProvider extends android.support.v4.content.FileProvider {}

Can anyone help me?

Capacitor 2.x uses AndroidX so I guess any plugin that uses the older Android support libraries won’t work.

Which plugin are you using exactly? The [Ionic Native one](https://ionicframework.com/docs/native/file)? Are you aware that there’s a [Filesystem API](https://capacitor.ionicframework.com/docs/apis/filesystem) that comes with Capacitor?

Hi! Same error, when I try to build for Android with Ionic Package:

```auto
/android/capacitor-cordova-android-plugins/src/main/java/org/apache/cordova/camera/CameraLauncher.java:40: error: package android.support.v4.content does not exist
import android.support.v4.content.FileProvider;

```

I saw it’s because Camera plugin uses AndroidX, but I am not able to find how to fix the issue! ☹

What should I do?  
Thanks!

I use “jetifier” for this on building my node\_modules. To rebuild I remove the node\_modules directory then run “npm i” to reinstall and jetifer will run after its complete and fixes those references.

> **[jetifier](https://www.npmjs.com/package/jetifier)**
>
> jetifier from Android Studio, in npm package format

Then in my package.json:

```auto
"scripts": {
    "ng": "ng",
    "start": "ng serve",
    "build": "ng build",
    "lint": "ng lint",
    "postinstall": "jetifier"
  }

```

I solved the following with

> npm install -D jetifier

**package.json** ( changes )  
change line  
“build”: “ng build”  
change to  
“build”: “npx jetifier && ng build”

**NOTE:**  
“postinstall”:“npx jetifier”
