Solved: Android SDK file not found: adb Error in Flutter
Introduction
Flutter is a popular cross-platform development framework for building apps for mobile, web, and desktop platforms. However, as with any complex framework, developers may encounter errors while building and running their applications. One such error is the “Android SDK file not found: adb” error, which can prevent your Flutter app from running on an emulator or physical device. In this article, we will discuss the causes of this error and provide you with step-by-step solutions to resolve it.
What is the Adb Error in Flutter?
The Adb error is caused when the Android SDK tools are missing from your system PATH environment variable. Adb (Android Debug Bridge) is a tool that allows you to communicate with an emulator or connected Android device for development purposes. Without adb, your Flutter app will not be able to compile and run correctly.
Causes of the Adb Error in Flutter
Here are some common causes of the Adb error in Flutter:
- Android SDK tools not installed or uninstalled incorrectly
- Android SDK tools not added to the system PATH environment variable
- Incorrectly configured environment variables
