Troubleshooting "undefined is not an object (evaluating 'RNSound.IsAndroid')"

paulmelnikow opened this issue 5 years ago · comments

The most common problem developers experience with this library is undefined is not an object (evaluating 'RNSound.IsAndroid').

This is caused by the library's native code not being linked. This is a tooling issue and seems to have a variety of different specific resolutions, depending on your environment.

react-native link react-native-sound
cd ios
pod install

fixed my problem

None of these fixed the issue in IOS at RN 0.60.4, also manual linking is not working at all.. So what to do?

@BenjaminLiCN i found this worked after I ran XCode -> clean build folder and then pod install

If I get it right, I can never get this to work when my App is made with Expo? I am new to React-native and just did buy a course to learn and wanted to try to implement react-native-sound and keep getting this error. My package.json looks like this: { "main": "node_modules/expo/AppEntry.js", "scripts": { "start": "expo start", "android": "expo start --android", "ios": "expo start --ios", "web": "expo start --web", "eject": "expo eject" }, "dependencies": { "expo": "^33.0.0", "pod": "^0.9.0", "react": "16.8.3", "react-dom": "^16.8.6", "react-native": "https://github.com/expo/react-native/archive/sdk-33.0.0.tar.gz", "react-native-sound": "^0.11.0", "react-native-web": "^0.11.4", "react-navigation": "^3.11.0" }, "devDependencies": { "babel-preset-expo": "^5.1.1" }, "private": true }

Edit: I guess I have to use this then? https://docs.expo.io/versions/latest/sdk/audio/

Edit 2: That seems to be it. You can't use native modules with Expo unless you want to work around it: https://docs.expo.io/versions/latest/expokit/eject/

*I will just leave this here in case it helps other people. I am probably not the only beginner trying to do this. Feel free to delete it if this does not belong here :)

@VictorVermeulen correct. It's not possible to use any module not supported by Expo when you're using expo, so your issue does not really belong here, and is a natural cause. So yes, if you're using Expo, you need to use the expo-av library (which is very unstable afaik..).

Anyway.

I'm getting this error on Android (not iOS) after linking. I've checked the manual linking steps as well, but it looks right to me (except the manual steps say compile while all other lines in my RN project say implementation so I'm assuming that the instructions are old..?

Here are screenshots from the changes applied in my project after linking (not displaying iOS here since it works there):

Adam Gerthel · Answer 11 · Wed Feb 19 2020 03:48:56 GMT+0800 (China Standard Time)

I just set up a brand new project using react-native init followed by yarn install react-native-sound and react-native link react-native-sound and got these changes after linking:

As you can see, one change is missing here, namely new RNSoundPackage(), in MainApplication.java,.

I eventually got past this error, but I have no idea how. Probably a combination of rebuilding node_modules, removing old builds, running ./gradlew cleanBuildCache etc.

Trevor Smith · Answer 13 · Sat Apr 25 2020 09:34:26 GMT+0800 (China Standard Time)

I had this issue when working with Android Studio and got past it, although my mistake was a pretty amateur one (note that this will be Android Studio specific). In the documentation, the React developers mention that you need to run both

$npx react-native start

and

$npx react-native run-android

to get the app running on your emulator. Well, the second command threw an error for me ("missing tool.jar" - that was a whole other nightmare to figure out), and there is a typo in the documentation that I found confusing. Since I could get my app to show up in the emulator while just running the first command, however, I continued only doing that. Turns out that the "react-native link react-native-sound" CLI command will not link this and other libraries properly if you don't actually run the second command. After managing to run "npx react-native run-android" without errors, I tried the "react-native link react-native-sound" command and it worked.

Beginner's mistake, but hopefully I will save somebody else some time by putting it here.

When I run "npx react-native run-android"
Still facing the issue for android "undefined is not an object (evaluating 'RNSound.IsAndroid')".
Anyone got the solution to resolve it. Please reply need urgently.

Richard Denton · Answer 15 · Wed Jun 03 2020 14:45:29 GMT+0800 (China Standard Time)

I fixed by performing the following

Stop any react-native processes you have running.
Uninstall your app from your emulator / phone.
Do react-native link react-native-sound
Clear Android build cache with cd android && ./gradlew cleanBuildCache
Start react-native with npm run start or whatever
Do a fresh build with npm run android or whatever.

enestatli · Answer 16 · Sat Aug 29 2020 23:43:06 GMT+0800 (China Standard Time)

In my case, I am able to solve this error, by re-linking the libraries react-native link (not only the react-native-sound) and installing the app npm run android again.

on Android Emulator:
"react": "16.13.1",
"react-native": "0.63.1",
"react-native-sound": "^0.11.0",

tatsianaBukzheleva · Answer 17 · Fri Oct 23 2020 16:12:19 GMT+0800 (China Standard Time)

Fixed this bug on react-native 0.61.5:
add in Podfile
pod 'RNSound', :path => '../node_modules/react-native-sound'
pod install

Trip Shanti · Answer 18 · Wed Dec 30 2020 19:52:49 GMT+0800 (China Standard Time)

RN 0.63.*

yarn
cd ios && pod install

Then you must close and re-compile app. Simply running yarn and pod install will cause OP's error.

I use this function successfully sovled my problem. anyone who use Expo can try this way.
