So I just created a react native project using the command

react-native init "project-name"

I went into the app level build.gradle to connect firebase and I had an error saying could not resolve symbol 'android' on the line

import com.android.build.OutputFile

However, it popped up saying "android framework is detected in the project click to configure" so I did this, but then it said cannot resolve symbol 'build' on the same line, I have no idea why it's saying this as I have made the project the same way before and never had this problem, any ideas?

In my case I was able to solve this by following those steps:

  1. Comment out the line like this: // import com.android.build.OutputFile
  2. Sync the project (click "Sync now")
  3. Comment in the line again like this: import com.android.build.OutputFile
  4. Sync again.

This might not work for everybody. In my case said import worked until I changed something somewhere in the project and suddenly the import failed. If the import never worked for you, this might not be the solution, but otherwise worth a try.

  • I'm really surprised, but this solution worked for me!! Thanks for the posting! My problem was with com.android.build.gradle.LibraryExtension, but it basically was the same issue. By the way, I was using that import in a number of places, so I commented out all usages before I ran the gradle sync. – Tom Rutchik Jan 25 '23 at 21:29
  • Thanks for the suggestion. Unfotunately it' hasn't worked for me... – Lauro235 Feb 27 '23 at 20:10

the thing that worked for me was

1- replace this line in build.gradle(:app)

def abi = output.getFilter(OutputFile.ABI)

with:

def abi = output.getFilter(com.android.build.OutputFile.ABI)

2- and click on sync project with gradle files (the elephant with blue arrow)

    As I set import of Output file, it was automatically removing the line for import, replacing this code really helped, Thank you for saving my day!! – Ayush Katuwal Apr 02 '22 at 09:26
  • Thanks for the suggestion, unfortunately it hasn't worked for me. – Lauro235 Feb 27 '23 at 20:11
  • @Lauro235 could you give more input, maybe I can help. – shiraz27 Mar 01 '23 at 06:56
  • Thanks Shiraz. I initialised with npx create-react-ntaive-app "dependencies": { "expo": "~47.0.12", "expo-splash-screen": "~0.17.5", "expo-status-bar": "~1.4.2", "react": "18.1.0", "react-native": "0.70.5", "react-native-auth0": "^2.17.1" }, "devDependencies": { "@babel/core": "^7.12.9", "metro-react-native-babel-preset": "^0.75.1", "react-native-dotenv": "^3.4.7" }, Android has always had a problem with BuildConfig I can run app with dev-client, but attempting development builds fail due to build config.. – Lauro235 Mar 01 '23 at 11:01
  • this might be coming late but here's my try: 1. try my solution 2. try cleaning the project and rebuilding it by selecting Build > clean project and then build > rebuild project from the Android studio menu. 3. select file > invalidate caches / restart from the Android studio menu. – shiraz27 Mar 09 '23 at 22:17

if you want to find the exact problem, go to the Android folder and assembleRelease using the terminal window:

 cd android
 .\gradlew assembleRelease

my problem was with the crashlytics package that was needed another version of the react-native-firebase/app package

installing the recommended version solved my problem

Try double click on build word in your code such as Build.VERSION, not in the import com.android.build.OutputFile. then if it show press ALT + Enter, you should do it.

Change the classpath 'com.android.tools.build:gradle:3.4.1' to 3.4.2 in your package build.gradle file

For me, i was using

classpath 'com.android.tools.build:gradle:3.4.1'

Then i have just changed the version to 3.4.2 an the problem was fixed.

Be sure you have classpath 'com.android.tools.build:gradle:2.2.0' in the dependencies block of your app level build.gradle file.

    classpath 'com.android.tools.build:gradle:2.2.0' should be in the dependencies of Buildscript block not in the dependencies block of app level build.gradle – Habib Kazemi Jul 25 '19 at 18:47
