Unable to locate ADB.

If you are facing the issue of not being able to locate ADB, try the following solutions:

1. Check if Android SDK is installed on your computer. ADB is a part of the Android SDK, so if it's not installed, you won't be able to locate ADB.

2. Add the path of the Android SDK to your environment variables. To do this, go to System Properties > Advanced > Environment Variables > System Variables > Path. Click on Edit and add the path of the Android SDK to the list.

3. Check if ADB is installed correctly. Open the command prompt and enter "adb version" to check if ADB is installed and working properly.

4. If you are using a third-party tool like Genymotion or BlueStacks, make sure that the ADB binary is included in the installation directory.

5. If you are still unable to locate ADB, try reinstalling the Android SDK or the third-party tool you are using.

6. If none of the above solutions work, try using a different computer or contact the support team of the software you are using for further assistance.
