Installing the Android SDK on a Windows system can sometimes be problematic, especially when the setup fails to detect the installed JDK. This guide provides practical solutions to help you overcome this common issue.
Understanding the Issue
When attempting to install the Android SDK, you might encounter an error message stating that the JDK installation cannot be found, even though it is installed on your system. This issue is prevalent on Windows 7 x64 systems but can also occur on other versions of Windows.
Step-by-Step Solutions
1. The Simple Back-Next Trick
One of the simplest and most effective solutions is to:
- Press the Back button when you receive the notification that the JDK cannot be found.
- Then press the Next button again. This often resolves the issue and allows the installer to detect the JDK.
2. Setting Environment Variables
If the Back-Next trick does not work, you can try setting the JAVA_HOME environment variable:
- Open the Start Menu and search for “Environment Variables”.
- Click on “Edit the system environment variables”.
- Under the “System Properties” window, click on the “Environment Variables” button.
- In the “System variables” section, click “New” and set the variable name to
JAVA_HOMEand the variable value to the path of your JDK installation (e.g.,C:/Program Files/Java/jdk1.8.0_11). - Click “OK” to save the changes.
Make sure to use forward slashes (/) instead of backslashes (\) in the path.
3. Modifying the Path Variable
Another method involves modifying the system Path variable:
- Open the “Environment Variables” window as described above.
- In the “System variables” section, find the
Pathvariable and click “Edit”. - Add the JDK path to the beginning of the Path variable (e.g.,
%JAVA_HOME%;C:\...). - Click “OK” to save the changes.
4. Using the Zip Archive
If the above methods do not work, you can try downloading the .zip archive of the SDK instead of the .exe installer:
- Download the .zip archive from the official Android developer website.
- Extract the contents of the archive to a directory of your choice.
- Run the
SDK Manager.exefrom the extracted directory.
Conclusion
By following these steps, you should be able to resolve the issue where the Android SDK installation does not find the JDK on your Windows system. These solutions are effective and have helped many developers successfully install the Android SDK.
