Won't find Android studio emulator. #1

maotora · 2018-01-15T13:21:09Z

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.

The text was updated successfully, but these errors were encountered:

@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.

enero-o · 2018-03-27T20:25:36Z

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 · 2018-04-04T11:52:07Z

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 · 2018-08-23T07:59:21Z

@maotora , any thing?

himankpathak · 2018-08-23T12:46:18Z

Facing the same issue, any fix yet?

jitish1 · 2018-10-11T17:53:25Z

Hi, this might resolve the issue ---

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

maotora · 2018-10-12T07:07:42Z

I didn't work, sadly.

moonstruck · 2018-10-12T12:28:47Z

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?

jitish1 · 2018-10-16T13:25:11Z

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

maotora · 2018-10-17T08:05:23Z

Now I feel stupid..

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.
Ran npm install & react-native link
Ran react-native run-android

Gets a different error.

@maotora Give the dev branch a try.

maotora · 2018-10-23T10:23:43Z

@moonstruck that's the only branch I have.

moonstruck · 2018-10-23T10:47:51Z

@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

devt3000 · 2019-04-26T22:55:29Z

Hey, is the dev branch still working?

I found that specifically adding the emulator path (and in fact the platform-tools) folders to my PATH environment variable, those issues go away. Why it doesn't append to the ANDROID_SDK_ROOT environment variable in Windows I'm not sure.

RichardFisher8410 · 2020-04-01T14:45:38Z

Hi Guys, if anyone still has this issue. An easy fix is just to open the 'android' folder from your react-native project in android studio and build directly from there. None of the other solutions above worked for me. however this worked straight away.

where did you build? I dont have a build button when I go into Android studio -> Android folder.

Make sure you're opening the build.gradle file found in the /android directory in your react-native app folder when opening in Android Studio. Then you should be able to press the green 'play' button at the top of Android Studio. If this doesn't work make sure you've opened the emulator first and have it selected in the dropdown menu next to the 'play' button. Hope this helps :)

vaibhavarora14 · 2020-11-19T09:01:24Z

Flutter is able to detect open emulator, but react-native is not able to.
Facing same issue as others are facing it here.
What's the final call for resolution?
