How Can I run react-native app in my mobile because avd is too slow

Please help me. My React Native app is not running in my mobile. It works fine on the android simulator, but the performance is quiet bad.
The error is:
$ react-native run-android

Try React Native environment to upgrade your environment because there is a thread in here Grovy Error

It's simple , just connect your mobile with Android studio and on the developing mode , then select the device from Android studio and run the project the app will simply open on your phone , unless you don't have any errors in enviornment.

React Native, why react-native run-android not working?

I'm trying to run react native run-android after I update my project file, but whenever I run react-native it throws an error. When I created that project and that command it worked fine but when I edit and add some files like apps/redux, apps/components, screens etc it stopped working. Can anyone tell me why it's not working?

you either need to create a virtual device or connect a physical device with USB debuging enabled (https://developer.android.com/studio/debug/dev-options).
To create a virtual device, open android studio and select AVD manager from Configure menu and create a new virtual device downloading required packages.

In case you are using a virtual device with Android studio then try to manually run the emulator BEFORE react-native run-android.
(open android studio > Tools > AVD Manager > Create Virtual Device)

Or repeat the official installation guide:

error Command failed: ./gradlew app:installDebug. Run CLI with --verbose flag for more details.
But it runs if I run it as root `sudo react-native run-andoid'.
How can I make the project run without being root??

I found out from reading the post by Medium that u have to give permission to every folder explicitly when u encounter a permission issue when installing react native and realated tools, so that u can run the app without being sudo. Otherwise the files installed by sudo can only be run as sudo.
Use the below command to give access to the current user for that specific folder
sudo chown -R $(whoami) ~/Documents/Myapplicationfolder

SDK location on android studio : /home/rojib/Android/Sdk, Is there something wrong ?

Try this
enter this line to your package.json file in scripts
"android": "ANDROID_HOME='Your android SDK Location' node node_modules/react-native/local-cli/cli.js run-android",
and after enter this line open terminal and run this
npm run android
hope it'll work for you...
