更新到 Android Studio 4.2 后无法构建我的项目

Question

I have recently upgraded to Android Studio 4.2. I can no longer build my project.

Android Studio non-stop trying to start Gradle Daemon , but cannot do so:

Starting Gradle Daemon...
Gradle Daemon started in 5 s 92 ms
Starting Gradle Daemon...
Gradle Daemon started in 4 s 406 ms
Starting Gradle Daemon...
Gradle Daemon started in 2 s 968 ms
Starting Gradle Daemon...
Gradle Daemon started in 2 s 937 ms
Starting Gradle Daemon...

I think as a result of this, dozens of OpenJDK Platform binaries are being generated in my TaskManager . This processes never stops until my machine runs out of memory. In such cases, very frequently, Android Studio is crashing.

When I do get to point where Android Studio stops building, it shows me an error: (I am sorry I am posting error image. My laptop is frozen that it is not possible to copy the error message.)

Answer 1

Studio tries to import previous.vmoptions and sanitize them to work with the garbage collector used by JDK 11. If that process fails, the IDE may not start for certain users who set custom VM options in the.vmoptions file.

In order to resolve this problem, try:

We recommend commenting out custom options in.vmoptions (using the “#” character). The.vmoptions file can be found in the following locations:

Windows

C:\Users\YourUserName\AppData[Local|Roaming]\Google\AndroidStudio4.2\studio64.exe.vmoptions

Answer 2

Potential solutions:

Solution 1.

Restart your machine. Then re-open your project. It should fix the issues.

Solution 2.

It is possible that Android Studio 4.2 is having issues due to an invalid Android Studio configuration imported from a previous version of Android Studio or an incompatible plugin

Go to these folders:

C:\Users\YourUserName\AppData\Local\Google

C:\Users\YourUserName\AppData\Roaming\Google

Find Android Studio 4.1 or similar directory of previous version of Android Studio. Delete (or rename, for backup purposes) the directory, depending on the Android Studio version, and start Android Studio again.

Answer 3

Try opening build.gradle and there at the top you will see JDK not recognized dialog click on it and choose your JDK. It will work.
