Why Is My Gradle Daemon Failing to Start in Android Studio and How Can I Fix It?

Troubleshooting "Unable to Start the Daemon Process" Error in Android Studio Gradle Project

Android Studio users may encounter an error stating, "Unable to start the daemon process. This problem might be caused by incorrect configuration of the daemon." This error often occurs during project initialization and can be frustrating to resolve.

Understanding the Error

The error message indicates that the Gradle daemon, a separate process that handles project builds, cannot be started. This could be due to incorrect Java Virtual Machine (JVM) settings, specifically related to memory allocation.

Cause of the Problem

In the provided example, the user is experiencing a memory allocation issue. The error message suggests that the JVM ran out of memory while initializing the object heap, possibly due to a large project or insufficient memory allocation settings.

Solution

The suggested solution involves adjusting the JVM memory settings in the Gradle properties file:

1. Open the project's gradle.properties file in Android Studio.
2. Add the following line to the end of the file: org.gradle.jvmargs=-Xmx1024m
3. This line increases the maximum heap size for the JVM to 1024 megabytes (1GB).
4. Save the file, close and reopen the project, or simply clean and rebuild it.

Expected Result

After making these changes, the Gradle daemon should start successfully and the project should build without the "Unable to start the daemon process" error. If the issue persists, it is recommended to increase the heap size further or investigate other potential causes, such as antivirus software interference or incompatible plugins.
