How to Set Java SDK Path in Android Studio?

16 Jun, 2021
The Java SDK for Android is a sophisticated suite of tools for managing, monitoring, profiling, and debugging Java code written in Android Studio. But sometimes as software is unpredictable you might be caught in an error that Android Studio stopped compiling projects and says that it can’t locate the 1.7.0_21 folder. Well, this is exactly what is referred to as a missing Java SDK Path. 
There are several methods that can help you resolve this issue, the ones which have the highest score in fixing this problem are mentioned below:
Navigate to File > Project Structure > SDK Location. Upon navigating there you will find that a tab named “JDK Location”, select that and then you can set the JDK path for the current project on which you’re working.

Chances are that you might be rocking an older version of Android Studio, if yes then
Navigate to File > Project Structure > [Platform Settings] > SDKs
You’ll then need to either update your current SDK setup to make use of the new directory or create a new directory and then adjust the settings in your project to make use of the new directory. This will make it applicable to the present project.
Sometimes only updating your SDKs won’t allow you to compile projects just because the SDK has lived its life and requires an update to itself. In that scenario, you’ll need to recreate the configurations from 0.
Navigate to Project Structure > Platform Settings > SDKs and click the “+” button.Go to your Android SDK folder and select “Choose” on the pop-up.A new pop-up window will open, asking which SDK and JDK you’d want to use. Select any Android SDK and the JDK 1.7.
Navigate to Project Structure > Platform Settings > SDKs and click the “+” button.
Go to your Android SDK folder and select “Choose” on the pop-up.
A new pop-up window will open, asking which SDK and JDK you’d want to use. Select any Android SDK and the JDK 1.7.
Note: Change your Project SDK to the one you just established under Project Structure > Project Settings > Project. The name of the SDK should now include the new Java version that you installed.
If you want to be a Geek and the above methods are just too much GUI for you, you might want to handle the SDK path using the terminal. In order to achieve that using the command line, follow the below commands in the Android Studio’s Terminal
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)
then
C:\Program Files\Android\Android Studio\jre\oldjre\
and just like that, you’ve achieved the desired result
Note: the ‘oldjre‘ here refers to your old JRE path
If you are on Android Version 3.2 or older then you’ll be having the option of using the embedded JDK & SDK for your project and that is one of the optimal ways you can fix this issue as Android Studio will handle the management of the services in the Backend!
Navigate to File > Project Structure > JDK Location and Checkmark the box saying “Use embedded JDK (recommended)”.

If all the above-mentioned ways didn’t work out for you, the best you can do is to get the SDK path of another Android Studio Project and then providing that path to your particular project (as in Method #1)
Press Ctrl (Command on Mac) + Alt + Shift + S
Then in the SDK Location tab, you will find your SDK Location, just copy it and paste it in the SDK Location as mentioned in Method #1.
