TLDR

To resolve the "no JDK found" problem when installing Android Studio on Windows 7, firstly install the JDK from Oracle's JDK download page. Then, assign your JAVA_HOME environment variable to your JDK install path (like C:\Program Files\Java\jdk1.8.0_231). Lastly, adjust your system Path to have the JDK's bin directory (like ;C:\Program Files\Java\jdk1.8.0_231\bin). Validate the setup with java -version and javac -version commands in your command prompt.

Setting environment variables

Proper configuration of environment variables is critical, as Windows requires JAVA_HOME and Path.

  • Assign JAVA_HOME to the root directory of the JDK installation, not the bin folder, with the Path variable pointing to %JAVA_HOME%\bin.
  • If JAVA_HOME still doesn't work, try creating a new system variable named ANDROID_STUDIO_JDK and set it to the JDK path.
  • The changes take effect after a system restart.
  • To check your environment variables, run exports or set in your console.

Configuring Android Studio

Post-installation, Android Studio will need some configuration adjustments.

  • Update your Android Studio's Project Structure with the new SDK path if you've relocated the SDK.
  • Make sure the correct SDK platforms and tools are installed via the SDK manager.
  • Correct any invalid paths in the SDK templates if prompted by Android Studio.

Troubleshooting installation issues

A few common mishaps to look out for if you encounter issues:

  • Compatibility issues may arise with JDK 1.7, as Android Studio needs JDK 1.8 or later.
  • Incorrect paths or typos in your environment variables can cause errors in the JAVA_HOME or Path.
  • Multiple JDK installations may cause clashes.
  • A fresh JDK installation may be needed if problems persist.

Tips for advanced setup

For an optimized setup, consider these:

  • Do follow the detailed installation steps with images from the official documentation if they're available.
  • Combine different solutions from across the internet.
  • Having both the JDK and JRE paths in your Path variable could sometimes be favourable

Choosing the right JDK version

Not every JDK version fits all.

  • Depending on your project needs, consider getting a specific JDK version from AdoptOpenJDK or other providers.
  • If needed, pick the stable LTS release for peace of mind.

In a team? Share your setup!

When working with a team, standardize your development environment.

  • Set the JDK path in the gradle.properties file.
  • Share your environment variable setup with the team.
