Android: Error cannot find symbol NotificationCompat.DecoratedMediaCustomViewStyle

Question

I'm following android's documentation on creating a custom notification for media playback controls. I read that it was recommended to set the style of the notification to DecoratedMediaCustomViewStyle, however this gives me the following compilation error.

error: cannot find symbol class DecoratedMediaCustomViewStyle

I'm importing DecoratedMediaCustomViewStyle from android.support.v4.app.NotificationCompat. When I try and use DecoratedCustomViewStyle, my media playback buttons in my notification do not work. But when I exclude setting the style, then my buttons work but the notification isn't decorated with the large icon and title.

Any help is appreciated.

Answer 1

This worked for me rather

import androidx.core.app.NotificationCompat; 

instead of android.support.v4.media.app.NotificationCompat OR android.support.v4.app.NotificationCompat

Answer 2

I found it. I had to import from android.support.v4.media.app.NotificationCompat instead of android.support.v4.app.NotificationCompat.

Answer 3

I have been getting this error for a npm package I use (/@aws-amplify/pushnotification) when assembling release build (./gradlew assembleRelease) in a react-native project.

Resolved with Jetifier, which can be done by:

yarn add jetifier --dev or npm install jetifier --save-dev

Then adding these to scripts in package.json:

  "postinstall": "jetify",
  "jetify": "npx jetify"

Then run yarn run jetifier or npm run jetifier

./gradlew clean && ./gradlew assembleRelease and build is successful. I assume androidx related issue.
