Understanding the CommandInvocationFailure Error

The “commandinvokationfailure” error essentially means a command failed to execute correctly.

Common Causes of the Error

  • Incorrect JDK Path: The build tools might be looking for the JDK in the wrong location. This is common if you have multiple JDK versions installed or have recently moved your JDK installation.
  • Corrupted JDK Installation: A corrupted JDK installation can prevent the build tools from accessing necessary files.
  • Environment Variable Issues: Incorrectly configured JAVA_HOME or PATH environment variables can also lead to this error.
  • Compatibility Issues: Occasionally, compatibility issues between your project’s Gradle version, the Android SDK, and the JDK can cause build failures.
  • Missing Dependencies: Missing or outdated dependencies in your project can sometimes trigger this error.

Troubleshooting the “commandinvokationfailure failed to build apk c program files java jdk1.8.0_121” Error

Here’s a step-by-step guide to troubleshoot this error and get your APK building successfully:

  1. Verify JDK Installation: Ensure that JDK 1.8.0_121 (or a compatible version) is correctly installed on your system. Try running java -version and javac -version from your command prompt to check if the JDK is accessible.

  2. Check JDK Path in Android Studio: Open your project in Android Studio and navigate to File > Project Structure > SDK Location. Ensure the JDK location points to the correct directory. If not, update it to the correct path “C:Program FilesJavajdk1.8.0_121” or wherever your JDK is installed.

  3. Set Environment Variables: Set the JAVA_HOME environment variable to your JDK installation directory and update the PATH variable to include the JDK’s bin directory. This ensures that the build tools can locate the necessary Java executables.

  4. Invalidate Caches and Restart: In Android Studio, go to File > Invalidate Caches / Restart. This can resolve issues related to cached build configurations.

Advanced Troubleshooting Steps

If the above steps don’t resolve the issue, try these advanced solutions:

  1. Update Gradle and Android SDK: Ensure that you’re using the latest versions of Gradle and the Android SDK. Outdated versions can sometimes lead to compatibility issues.
