React Native：无法确定任务“：app：installDebug”的依赖关系

Question

I`ve been trying to run the default React Native App in my Android Emulator from Android Studio.

Yesterday I got the message that the Android sdk cant be found so i created the local.properties file in my android folder with (sdk.dir = C:\\Users"MyUserName"\\AppData\\Local\\Android\\Sdk).

That worked but now i get another problem:

FAILURE: Build failed with an exception.

* What went wrong:
Could not determine the dependencies of task ':app:installDebug'.
> java.io.IOException: Die Syntax fuer den Dateinamen, Verzeichnisnamen oder die 
Datentraegerbezeichnung ist falsch

* Try:
Run with --stacktrace option to get the stack trace. Run with --info or --debug option to get 
more log output. Run with --scan to get full insights.

* Get more help at https://help.gradle.org

BUILD FAILED in 11s

error Failed to install the app. Make sure you have the Android development environment set up: 
https://reactnative.dev/docs/environment-setup. Run CLI with --verbose flag for more details.
Error: Command failed: gradlew.bat app:installDebug -PreactNativeDevServerPort=8081

I tried cd android -> gradlew clean but got the same Problem.

I also tried npm install --save-dev jetifier -> npx jetify -> npx react-native run-android but got the same Problem.

I googled for about 4 hours but cant find anything the solves my problem.

Im pretty new to react and react native but thanks in advance for your help.

Use \\\\ instead of \\ in your pathvariable in local.properties

So this:

"sdk.dir = C:\\Users"MyUserName"\\AppData\\Local\\Android\\Sdk"

becomes this:

"sdk.dir = C:\\\\\\Users"MyUserName"\\\\\\AppData\\\\\\Local\\\\\\Android\\\\\\Sdk"
