I have the template code for my "Helloworld" app written in javascript and react-native on Windows. I connected my android emulator and wanted to launch the app on it. The following happens when I run "react-native run-android" command. Node.js opens as a separate window and it's written "Loading dependency graph, done". However, in the terminal window, there is following error message:
>User helloworld $ react-native run-android
Starting JS server...

Make sure you have an Android emulator running or a device connected and have
set up your Android development environment:

-Concerning whether emulator is connected:
$ adb devices
List of devices attached
emulator-5554 device
(Works similarly for my Android smartphone). USB debugging is enabled.
-Concerning what I have tried to solve the problem:
- My user is set as administrator.
I had JDK11.0.1 version. I installed JDK1.8.0_201 and it is now set as my java version.
User helloworld $ java -version java version "1.8.0_201"I created ".gradle" folder in my project's directory in case there are problems with accessing/creating this kind of folder.
-I specified the path for sdk.dir in local.properties file
-My OS is Windows 8.1. Gradle's version is 4.7.
-I have installed Android Studio, JDK8 and 11.
-I am using GitBash for the terminal purposes.
-I have the following system's environment variables:
ANDROID_HOME = c:\Users\User\AppData\Local\Android\Sdk
GRADLE_HOME = C:\Users\User.gradle\wrapper\dists\gradle-4.7-all\4cret0dgl5o3b21weaoncl7ys\gradle-4.7
JAVA_HOME = C:\Program Files\Java\jdk1.8.0_201

In case you are interested what was in the question before: My initial problem was that there just was not any error shown, but still nothing was launched on the emulator. I went around that by putting my project's "android" folder into Android Studio and it launched the app on my smartphone. However, when I introduced small changes to App.js, the project could not be updated due to some unknown error, and I couldn't reopen it as a new project. So I had to solve this problem by trying to run the app by using "react-native run-android" through terminal, and now I'm at this state of the problem.
