Error migrating to AndroidX

[SystemBlad]

Hi,
I using this great library and I was trying to migrate my react native project to AndroidX but the following error is show:

Error:
package android.support.v4.content does not exist

In the file:
android\src\main\java\com\vinzscam\reactnativefileviewer\RNFileViewerModule.java

Line:
8

Do you know when I will be able to use this library with AndroidX?

Thanks.

I ran into this same issue. Opened up #50

[vinzscam]

AndroidX is not yet included in react-native projects. #50 includes many unnecessary files and it doesn't keep retro compatibility with current projects.

I would recommend to append the following snippet to your android/app/build.gradle file:

preBuild.doFirst {
    ant.replaceregexp(match:'android.support.v4.content.', replace:'androidx.core.content.', flags:'g', byline:true) {
        fileset(dir: '../../node_modules/react-native-file-viewer/android/src/main/java/com/vinzscam/reactnativefileviewer', includes: '*.java')
    }
}

Let me know if that works.

@vinzscam is working using the snippet code thanks.

FWIW. The AndroidX migration stuff was merged into React Native. facebook/react-native#23112. It seems like its coming in 0.60.

When I do this, in Android Studio, the project seems to build fine, but when i run react-native run-android, it gives me the same errors again
