Install Android Studio
Android Studio is an Android integrated development environment (IDE) that is officially distributed by Google. It is based on IntelliJ IDEA and uses the open source Gradle build system.

keytool.exe file path Add to environment variable
If you have installed Android Studio, add keytool.exe to your PATH.
keytool.exe is the file used to sign the application. Android must be signed by the application before it can be deployed to Google Play. So for distribution, Android uses Java’s keytool.exe to create a public and private key pair, and stores the two generated keys in the keystore.
To add the keytool.exe file to your PATH:
First press the Windows key + R and type sysdm.cpl in the Run window. When you type sysdm.cpl, the System Properties window of Control Panel appears.
In the System Properties window, click Environment Variables on the Advanced tab and select PATH. Then click [Edit] to add the path below.
C:\Program Files\Android\Android Studio\jre\bin
The above path may vary depending on the path where Android Studio is installed.
After adding the path, you should check to make sure it is set up properly. Open the cmd window and type keytool.
If keytool is typed and you see the following screen, the setting is correct.
