This project was able to be built a couple of days ago. However, without any changes, I face the aforementioned error.

I googled and found the following pages:

react-native run-android: daemon startup failed

can't compile and run my react native app

I did tried both of them, but none of them worked.

Any Ideas??????

• javascript
• react-native

• did you try deleting the signing file? app\build\intermediates\signing_config\debug\out\signing-config.json – X3R0 Commented Sep 1, 2019 at 7:58
• also did you try closing the cli tool and all open files, and closing the server, then emptying the build folder. then rebuilding it? – X3R0 Commented Sep 1, 2019 at 7:59
• 1 the links I mentioned in question, suggested your solutions. I did the same, I even delete the whole build folder. Still no changes in error. – Ata Iravani Commented Sep 1, 2019 at 8:04

Solution 1: Delete the android/app/build folder and try to build again. It should work

Solution 2: run npm i --save @react-native-community/cli-platform-android

1. First make sure your are on cmd admin
2. run cd android && gradlew clean
3. If it give you error while gradlew clean then goto project/android/app/build/intermediates/ and delete signing_config folder
4. run gradlew clean
5. run react-native run-android

Most likely some of your dependencies changed, made a big update and overrode some of your dependencies. So, do the following:

1. Remove all your ^ from the package.json. That is saying to NPM or YARN that is OK to update to a more updated version of your packages. Usually, you don't want that as this might happen.

2. Nuke your node_modules and re install everything.

Delete ./android/app/build/ folder And try to run again. Worked for me

Try updating the Node to the version 10.17.0. It helped me.

I was getting same error because this line was missing in manifest file

 xmlns:android="http://schemas.android.com/apk/res/android" 

Close your IDE, and run the cmd as administrator to compile the project

I fixed this problem with this steps:

• Remove the folder /node_modules
• Run yarn install or npm install
• From android studio, select Build/Clean Project

After trying what they say and it didn't work, I went back to the latest version of the git, ran npm install, and it ran perfectly.
