Troubleshooting Common Issues

Build Failure - SDK Path Error:

• Problem: When running npx react-native run-android, the build failed with an exception stating that the SDK location was not found. Specifically, it mentioned a "Trailing char < > at index 40" error, indicating an issue with the SDK path.

• Resolution:

  • Verified the local.properties file in the D:\MyProject\android directory.

  • Ensured that the sdk.dir path was correctly set to C:\\Users\\shubh\\AppData\\Local\\Android\\Sdk with no trailing spaces or hidden characters.

  • The local.properties file was recreated using a command to avoid any formatting issues.

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

Environment Variable Issues - ANDROID_HOME:

• Problem: The ANDROID_HOME environment variable was not set correctly, leading to issues in locating the Android SDK.

• Resolution:

  • The ANDROID_HOME environment variable was manually set to the correct SDK path.

  • The variable was verified and set permanently in the system's environment variables.

Final Build Failure - Java Dependency Issue:

• Problem: The build failed again with an error related to Java dependencies, specifically involving a "Trailing char < > at index 40."

• Resolution:

  • Ensured that the local.properties file had no hidden or extra characters.

  • Rechecked and corrected the local.properties file, ensuring the SDK path was correctly formatted.

  • Rebuilt the project using the gradlew clean command to ensure a clean environment.

• The issues were resolved by carefully verifying and correcting the SDK path in the local.properties file, setting the ANDROID_HOME environment variable, and ensuring no extraneous characters were causing the build to fail.
