Addressing Network Issues

The "Gradle Failed to Sync" error can sometimes be caused by network problems or improper proxy settings. Let's take a closer look at how to troubleshoot and fix these network-related issues.

Checking Internet Connection

First, make sure your device has a stable and reliable internet connection. Check the connectivity status of your device or test it with other web-based applications. If you're getting slow or no internet, it's likely the network is causing the Gradle sync failure.

Configuring Proxy Settings

Proxy settings can also cause network problems causing gradle sync failures. If your device uses a proxy server, make sure it's set up right for Gradle. Here's how to configure proxy settings for gradle:

  1. Open the Android Studio settings and go to the "Gradle" section.
  2. Find the "Gradle JVM arguments" field and add this line: -Dhttp.proxyHost=your_proxy_host -Dhttp.proxyPort=your_proxy_port
  3. Replace "your_proxy_host" and "your_proxy_port" with your proxy server's details.
  4. Save the changes and try to fix gradle sync issues due to internet connection by syncing your project again.

By fixing network issues and ensuring a stable internet connection and correct proxy settings, you can often solve the "Gradle Failed to Sync" error in Android Studio.
