After creating a react native project, I tried to run it on my android device. I enter adb devices into the terminal, I saw my device. I ran react-native run-android. And after a while Task 'installDebug' not found in project ':app' popped up.

I ran gradlew tasks and I did not see installDebug under the install tasks. I am sure that I set up the environment variables correctly, including android SDK, JDK. I tried reinstalling react-native. I put the location of my sdk in local.properties under android folder. I ran gradlew installDebug and installDebug not found in root project '[app's name]' appeared. None of the solutions on the internet worked.

Can anyone please help me to sort out this? Thank you.

I also faced the same problem. Here is what works for me.

I opened the Android Project in Android Studio. This can be located at YourReactNativeProjectFolder/android

When I opened this project in Android Studio, it was missing the configuration. Wait for some time and allow Android Studio to configure it and ask you to update the Gradle. Update the Gradle and now you can run your project from the Android Studio or using the command line "npx react-native run-android"

I hope that it will be helpful.

try the following command at the project root:

cd android && ./gradlew assembleDebug && ./gradlew installDebug

The solution is loading the /android folder in the Android Studio and let it update the Gradle. After that you will be able to run react-native run-android

1.- npx react-native run-android raises metro terminal(stay open metro).

2.- open proyect in Android in the folder android and launch Emulator on Device.(wait....).

3.- later android launch the app and Device error.

4.- in terminal type 'adb reverse tcp:8081 tcp:8081'(in the folder android).

5.- in Device press reload
