操作无法完成。 找不到 Java 运行时。 有关安装 Java 的信息，请访问 http://www.java.com

Question

I couldn't run the flutter app on android emulator or android phone. I installed the recently released android studio for arm-mac platform on m1 mac. Please answer if I am doing anything wrong here or is it the problem with the release itself.

Debug console output:

The operation couldn’t be completed. Unable to locate a Java Runtime.
Please visit http://www.java.com for information on installing Java.

Exception: Gradle task assembleDebug failed with exit code 1

flutter doctor -v output :

Go to Applications then right click on Android Studio, then choose "Show Package Contents", create a new folder inside jre named jdk and copy the contents of jre to jdk

Answer 2

I was able to fix my issues by doing the following, I sync my project with Gradle files

I downloaded Java 8 (but I don't think this guy did the work)

Answer 3

I encountered this issue because I didn't have Java installed. If you can't see a Java icon under System Preferences, Java 7 or later versions is not installed. Link to java.com
