Won't find Android studio emulator.

[maotora]

Hi,

am running your app on an android studio emulator and it looks like this demo can't find it!

Whenever I run react-native run-android it gives error

Scanning 767 folders for symlinks in /home/user/Projects/Phones/react-native-track-player-demo/node_modules (7ms)
JS server already running.
Building and installing the app on the device (cd android && ./gradlew installDebug)...
Could not install the app on the device, read the error above for details.
Make sure you have an Android emulator running or a device connected and have
set up your Android development environment:
https://facebook.github.io/react-native/docs/android-setup.html

My emulator is up and other projects can use it and install apps normally.

@maotora You may specify which emulator to run on like ..
react-native run-android --deviceId emulator-5554

To get list of emulators run
adb devices -l

@moonstruck Hi.

Thanks for replying.

I tried your method unfortunately still fails.

The problem is not that it cant find the Android Emulator, There's an error in compiling your projects, have you linked your dependencies well ?

[maotora]

Hi @aivene25 ,
Thank you for your response but it still doesn't work.

I re-cloned the project, then ran yarn then react-native link then ran yarn again then npm run start and lastly react-native run android still same issue.

[ithustle]

@maotora , any thing?

[himankpathak]

Facing the same issue, any fix yet?

[jitish1]

Hi, this might resolve the issue ---

1. Just run sudo chmod -R 777 react-native-track-player-demo(Project Name) after that
2. npm install
3. react-native link
4. react-native run android

[maotora]

I didn't work, sadly.

This repo is not active for last couple of months.
Try the new example Instead.

Hello @moonstruck ,

I tried your solution and it gave a different error.

I can see some light in this, do you have any solutions to this issue?

Hi @maotora
change your version in package.json
"react-native-track-player": "git+https://github.com/rm3rdmodules/react-native-track-player.git#dev",

[maotora]

Now I feel stupid..

1. Changed the "react-native-track-player" to "git+https://github.com/rm3rdmodules/react-native-track-player.git#dev" and "version" to "0.0.2" in package.json.

2. Ran npm install & react-native link

3. Ran react-native run-android

Gets a different error.

[moonstruck]

@maotora Give the dev branch a try.

[maotora]

@moonstruck that's the only branch I have.

[moonstruck]

@maotora Open emulator and try this
git clone https://github.com/react-native-kit/react-native-track-player.git
git checkout dev
cd example
yarn install
react-native run-android
