在 Android Studio 上运行应用程序，模拟器打开，但不显示应用程序

Question

hope you all doin fine.

I try to run my code in Android Studio(btw. if i do it on Visual Studio its the same), and the code is clean, he opens up the Virtual Device but doesnt show my app.

Launching lib\\main.dart on Android SDK built for x86 in debug mode... Running Gradle task 'assembleDebug'... e: java.io.IOException: Cannot run program "C:\\Users\\Tigran\\Desktop\\jdk-12.0.2\\bin\\java" (in directory "C:\\Users\\Tigran\\AppData\\Local\\kotlin\\daemon"): CreateProcess error=2, Das System kann die angegebene Datei nicht finden FAILURE: Build failed with an exception What went wrong: Execution failed for task ':app:compileDebugKotlin'. java.io.IOException: Cannot run program "C:\\Users\\Tigran\\Desktop\\jdk-12.0.2\\bin\\java": CreateProcess error=2, Das System kann die angegebene Datei nicht finden Try: Run with --stacktrace option to get the stack trace. Run with --info or --debug option to get more log output. Run with --scan to get full insights. Get more help at https://help.gradle.org BUILD FAILED in 2m 26s Finished with error: Gradle task assembleDebug failed with exit code 1

This is the error im getting back. And i can remember that when i updated Android Studio there was a little check mark on deleting directories or smth like that, and i did hit that, so i think it stands in some connection to this problem.

Does anyone know how to solve this problem?

I think the solution to this problem is as follows:

1-Open your flutter Project directory.

2-Change directory to android directory in your flutter project directory.

3-Pub get with file pubspec.yaml .

4-Clean Gradle and build gradle , if you need use this command ./gradlew clean build .

5- Run Project.

If that doesn't work, you should reinstall the Java JDK and repeat the same steps .
