How to set Java SDK path in AndroidStudio?

问题:

I had JAVA SDk 1.7.0_21 installed and I installed 1.7.0_45 today after uninstalling the previous version. Now AndroidStudio has stopped compiling projects and says that it cant locate the 1.7.0_21 folder. How can I set the new path for Java SDK? I have changed the environment variables also but didnt work.

回答1:

In IntelliJ IDEA (and likely the same in Android Studio) go to File > Project Structure > [Platform Settings] > SDKs. You'll need to either update you current SDK configuration to use the new directory, or define a new one and then change your project's settings to use the new one.

Go to File> Project Structure (or press Ctrl+Alt+Shift+S), A popup will open now go to SDK Location Tab you will find JDK Location there refer this image to be more clear.

I tried updating all of my SDKs by just going into the Project Structure > Platform Settings > SDKs and changing the Java SDK, but that didn't work, so I had to recreate the configurations from scratch.

Here's how to create your SDKs with the latest Java:

1. In Project Structure > Platform Settings > SDKs, click the "+" button to add a new SDK.
2. In the pop-up, go into your Android SDK folder and click "Choose"
3. Another pop-up will appear asking for which SDK and JDK you want to use. Choose any Android SDK and the 1.7 JDK.
4. Go to Project Structure > Project Settings > Project and change your Project SDK to the one you just created. You should see the name of the SDK contain the new Java version that you installed.

This problem arises due to incompatible JDK version. Download and install latest JDK(currently its 8) from java official site in case you are using previous versions. Then in Android Studio go to File->Project Structure->SDK location -> JDK location and set it to 'C:\Program Files\Java\jdk1.8.0_121' (Default location of JDK). Gradle sync your project and you are all set...

C:\Program Files\Android\Android Studio\jre\bin>java -version
openjdk version "1.8.0_76-release"
OpenJDK Runtime Environment (build 1.8.0_76-release-b03)
OpenJDK 64-Bit Server VM (build 25.76-b03, mixed mode)

Somehow the Studio installer would install another version under:

C:\Program Files\Android\Android Studio\jre\jre\bin>java -version
openjdk version "1.8.0_76-release"
OpenJDK Runtime Environment (build 1.8.0_76-release-b03)
OpenJDK 64-Bit Server VM (build 25.76-b03, mixed mode)

where the latest version was installed the Java DevKit installer in:

C:\Program Files\Java\jre1.8.0_121\bin>java -version
java version "1.8.0_121"
Java(TM) SE Runtime Environment (build 1.8.0_121-b13)
Java HotSpot(TM) 64-Bit Server VM (build 25.121-b13, mixed mode)

Need to clean up the Android Studio so it would use the proper latest 1.8.0 versions.

According to How to set Java SDK path in AndroidStudio? one could override with a specific JDK but when I renamed

C:\Program Files\Android\Android Studio\jre\jre\

to:

C:\Program Files\Android\Android Studio\jre\oldjre\

And restarted Android Studio, it would complain that the jre was invalid. When I tried to aecify an JDK to pick the one in C:\Program Files\Java\jre1.8.0_121\bin or:

C:\Program Files\Java\jre1.8.0_121\

It said that these folders are invalid. So I guess that the embedded version must have some special purpose.
